Setting up a Software Development Environment for Mac OS, Ubuntu Linux and Windows

Sean E. O'Connor


I show how to set up a software development environment for Mac OS Ubuntu Linux and Windows When we're done, we'll be able to develop programs in C, C++, Python, Javascript, Java, and Lisp using Unix tools.

SYSTEM SETUP - Mac OS - Ubuntu Linux - Windows

Ubuntu Linux

I will install on an early era MacBook Pro: MacBook Pro (17-inch, Early 2009) running OS X El Capitan.

You can read through this excellent guide, which shows how to install a boot loader so you can dual-boot Mac OS and Linux, and how to convert and load a Linux distribution onto a USB drive so you can install Linux. How to install Linux on a Mac (the definitive guide)

Now you've got your USB drive containing the Linux distribution plugged into your Mac and your Ethernet cable hooked up to your internet provider. Boot up and hold down the Option key. Select the EFI Boot icon in the boot device menu.

Booting from the USB Boot Drive

Now go through the Ubuntu installation process. Pretty straightforward for the most part. You'll want to select both Download updates while installing Ubuntu and Install third-party software for graphics,...

Download Updates and Third Party Software.

You'll see This computer currently has no detected operating systems. Select Something else. Now you'll format the main disk drive (be careful that you don't overwrite your Mac OS drive, and create swap space. Format the Linux boot drive as Ext4 journaling file system with mount point /, then create a swap drive.

On the other hand, if you are reinstalling Linux, it's slightly different,

Enter user name and password. You will be the superuser.

Here's the Ubuntu desktop:

Finish up the Ubuntu installation by updating and upgrading all software. The upgrade will take some time.

sudo apt-get update sudo apt-get upgrade

You'll need to explicitly install the Wireless driver. I found it by looking at Broadcom Linux Wireless Drivers Install using the line below and reboot after you install.

sudo apt install bcmwl-kernel-source

Fixing cursor flicker. Go to System Settings > Displays. You will see two displays: a red and a green. Turn off the green display.

To read a USB drive formatted in Extended FAT format, install the drivers.

sudo apt-get install exfat-utils exfat-fuse

Install Vim first so you can edit files. To install file sharing across computers, find out your username

users seanoconnor

then install Samba

sudo apt-get install samba sudo smbpasswd -a seanoconnor mkdir /home/seanoconnor/share sudo cp /etc/samba/smb.conf ~

Edit the smb.conf file by adding these lines to the end,

[share] path = /home/seanoconnor/share valid users = seanoconnor read only = no

sudo apt-get install smbclient sudo service smbd restart

To speed up SMB sharing, (it still takes a minute or two on my Mac), add the IP addresses and hostnames of all your local computers to the /etc/hosts file

hostname seanoconnor-MacBookPro

The last two entries are my Ubuntu Linux computer and my Mac OS computer, localhost ... 333.333.3.33 seanoconnor-MacBookPro 333.333.3.34 Artificer

Go into the file manager, into Home directory, and in Properties, turn on sharing in Local Network Share and allow others to create and delete files. Now you can see your shared drive on another computer under the share name seanoconnor-mac, directory share with login password whatever you set for samba

Back on Mac OS, mount the shared remote directory,

cd ~/Desktop mkdir Ubuntu mount -t smbfs //seanoconnor:iforget@seanoconnor-MacBookPro/Desktop ~/Desktop/Ubuntu

To add a sort of Multitouch, install the touchegg app which runs as a daemon in user space.

sudo apt install touchegg

Edit or create a file ~/.xprofile in your home directory which reconfigures some keys and runs touchegg as a background process upon startup.

seanoconnor@seanoconnor-MacBookPro:~$ cat .xprofile synclient ClickFinger3=0 synclient TapButton3=0 touchegg &

Configure the gestures in the file ~/.config/touchegg/touchegg.conf ... ... # Three finger drag moves windows. ...

Then reboot so that touchegg gets loaded upon startup.

For debugging you can kill the background touchegg process, then run touchegg from the terminal window, and see commands being executed.

Mac OS runs .bash_profile first then .bashrc because it makes all terminal windows login windows. Not so for Ubuntu. So open Terminal->Preferences->Profiles->Edit->Command and turn on Run command as login shell.

Some other utilites you'll want to install are: Thunderbird email , Screenshot , Quadrapassel , Cheese Webcam Booth

Mac OS

You get everything installed out of the box.

Developer Tools Mac

Mac OS X comes with most of the the Unix utilities make, diff, gcc, g++ (the clang equivalent), lldb, etc. already installed. To get even more recent versions, you can install the free Xcode IDE.

Developer Tools Ubuntu Linux

Naturally, you've got all the unix tools or can easily install them using sudo apt-get from the terminal.

UNIX Tools Windows

Load Cygwin utilities from Cygwin home. Choose download to disk without installing to C:/Install/Cygwin Use direct connection and pick a mirror site. Next, run setup.exe. Pick view=full. Now select all the defaults and also be sure to add bash, bison, byacc, cvs, ctags, diff, flex, gcc, g++, gdb, hexedit, ncurses, make, python, sed, tar, zip and unzip. Then run setup again but this time install from the local disk. You'll get a cygwin icon on the desktop which you can launch shell commands from.

Bash Settings

I'm using the BASH shell. Read the Beginner's Guide, Tutorial, and Reference then go to your home directory, under C:/Documents and Settings/Sean Erik O'Connor and place the bash startup files .bash_login, .bash_logout and .bashrc there.

If your user name in your /home directory contains spaces, it will cause trouble. cygwin gets it from the windows logon name. You can edit the /etc/passwd file and change the Cygwin user name (first field), then rename your directory.

I use Git for source code control. It's out of the box in Mac OS and you can install in Ubuntu Linux using

sudo apt install git

It's described in the Git Pro 2 Book. Here's an example of how I set up my Git repository for my Primpoly project using local repositories.

Git Configuration.

In your .bashrc file in home directory, add the location of the local Git repository,

#------------- Git ------- # Location of git repository. export GITREPOS="${web_dir}/private/repos"

The bash parameter ${web_dir} points to my top level web directory on my disk.

In your home directory $HOME, edit the file .gitconfig to add your email and user name plus your default editor,

[user] email = name = Sean E. O'Connor [core] editor = vim excludesfile = /Users/seanoconnor/.gitignore [merge] tool = opendiff conflictstyle = diff3 [difftool] prompt = false # Don't prompt the user to hit RETURN before the next file difference. [difftool "opendiff"] # cmd = echo 'base(ancestor base for the merge) = ' \"$BASE\" 'local(file on current branch) = ' \"$LOCAL\" 'remote(file to be merged) = ' \"$REMOTE\" 'merged(what mergetool should write) = ' \"$MERGED\" cmd = opendiff \"$LOCAL\" \"$REMOTE\" -merge \"$MERGED\" [mergetool "opendiff"] cmd = opendiff \"$LOCAL\" \"$REMOTE\" -ancestor \"$BASE\" -merge \"$MERGED\" trustExitCode = true [push] default = simple [credential] helper = cache [alias] unstage = reset HEAD -- uncheckin = checkout --

and which files to ignore globally by git,

$ cd $ cat .gitignore *.html

Create a Bare Repository

Create a local directory to serve as the Git repository, make a subdirectory for the project, then initialize the repository.

cd $web_dir/private $ mkdir repos ; cd repos $ mkdir Primpoly ; cd Primpoly $ git --bare init Initialized empty Git repository in $web_dir/private/repos/Primpoly/ $ la HEAD branches/ config description hooks/ info/ objects/ refs/

Add Files to Source Code Control

Go to the directory containing the source files and initialize Git.

cd ~/Desktop/Sean/WebSite/Mathematics/AbstractAlgebra/PrimitivePolynomials/Project/SourceCode/Primpoly $ git init Initialized empty Git repository in /Users/seanoconnor/Desktop/Sean/WebSite/Mathematics/AbstractAlgebra/PrimitivePolynomials/Project/SourceCode/Primpoly/.git/

Place the source files under source code control. We don't add the html files since they are automatically generated.

$ git add *.cpp *.h /FactorTables $ git status On branch master Initial commit Changes to be committed: (use "git rm --cached ..." to unstage) new file: FactorTables/c02minus.txt ... new file: FactorTables/c12plus.txt new file: Primpoly.cpp ... new file: ppUnitTest.h Untracked files: (use "git add ..." to include in what will be committed) Primpoly.cpp.html ... ppUnitTest.h.html

Your files are staged now. When ready, do a commit,

$ git commit -m "Initial import from SVN." [master (root-commit) 75fa9b1] Initial import from SVN. 32 files changed, 46548 insertions(+) create mode 100755 FactorTables/c02minus.txt ... create mode 100755 FactorTables/c12plus.txt create mode 100755 Primpoly.cpp ... create mode 100755 ppUnitTest.h

Now we let the local directory Primpoly know about the remote repository.

$ git remote add origin $GITREPOS/Primpoly/ $ git remote show origin $ git remote -v origin ${web_dir}/private/repos/Primpoly/ (fetch) origin ${web_dir}/private/repos/Primpoly/ (push)

Then we push up to the remote repository,

$ git push origin master Counting objects: 35, done. Delta compression using up to 8 threads. Compressing objects: 100% (35/35), done. Writing objects: 100% (35/35), 1.10 MiB | 0 bytes/s, done. Total 35 (delta 2), reused 0 (delta 0) To $GITREPOS/Primpoly/ * [new branch] master -> master

To avoid specifying origin and master each time you pull and push, you can track the remote repository,

$ git pull There is no tracking information for the current branch. Please specify which branch you want to merge with. See git-pull(1) for details. git pull If you wish to set tracking information for this branch you can do so with: git branch --set-upstream-to=origin/ master $ git branch --set-upstream-to=origin/master Branch master set up to track remote branch master from origin.

Verify the git repository is set up correctly by doing a test clone from the remote repository, and verify there are no differences between it and your local repository,

$ cd ~/Desktop $ git clone $GITREPOS/Primpoly Cloning into 'Primpoly'... done. $ diff -r ~/Desktop/Primpoly \ ~/Desktop/Sean/WebSite/Mathematics/AbstractAlgebra/PrimitivePolynomials/Project/SourceCode/Primpoly

You can use Mac OS X mergetool/opendiff to resolve conflicts.

$ git mergetool


Somewhat long in the tooth, I use make


C++ Compilers

Start by reading the textbooks A Tour of C++ by Bjarne Stroustrup and The C++ Programming Language, 4th Edition then read the latest updates in the C++ Super-FAQ and the C FAQ

Mac OS X development tools contain the clang C++ and C compilers. They come with XCode.

Linux To get C++ and C working in Ubuntu Linux, install clang and explicity install one of its libraries,

sudo apt-get install clang sudo apt-get install libc++-dev

Compiles will fail, as shown here,

$ cat foo.cpp #include #include using namespace std; int main(int argc,char** argv) { string s(argv[0]); cout << s << endl; } $ clang++ -std=c++11 -stdlib=libc++ foo.cpp In file included from foo.cpp:1: /usr/include/c++/v1/string:1940:16: error: 'is_nothrow_copy_constructible' is not a class, namespace, or enumeration _NOEXCEPT_(is_nothrow_copy_constructible::value) ^ /usr/include/c++/v1/type_traits:3090:51: note: 'is_nothrow_copy_constructible' declared here template struct _LIBCPP_TYPE_VIS_ONLY is_nothrow_copy_constructible ^ In file included from foo.cpp:1: /usr/include/c++/v1/string:1938:44: error: 'basic_string<_CharT, _Traits, _Allocator>' is missing exception specification 'noexcept(is_nothrow_copy_constructible::value)' basic_string<_CharT, _Traits, _Allocator>::basic_string(const allocator_type& __a) ^ /usr/include/c++/v1/string:1326:40: note: previous declaration is here _LIBCPP_INLINE_VISIBILITY explicit basic_string(const allocator_type& __a) ^ 2 errors generated. # This is OK if we switch to the older GNU library. $ clang++ -std=c++11 -stdlib=libstdc++ foo.cpp

You must fix this STL bug by editing the file /usr/include/c++/v1/string and after line 1938, put this patch,

template inline _LIBCPP_INLINE_VISIBILITY basic_string<_CharT, _Traits, _Allocator>::basic_string(const allocator_type& __a) // Insert patch #if _LIBCPP_STD_VER <= 14 _NOEXCEPT_(is_nothrow_copy_constructible::value) #else _NOEXCEPT #endif // End of patch : __r_(__a) { #if _LIBCPP_DEBUG_LEVEL >= 2 __get_db()->__insert_c(this); #endif __zero(); }

If that doesn't work, change your makefiles by replacing the default library -stdlib=libc++, with the older GNU library -stdlib=libstdc++

Windows You can use the C++ compiler in the Cygwin development tools or you can download Visual Studio Express and follow instructions.

C++ GUIs

I haven't tried them yet but the C++ GUIs FoxTookit and WxWidgets sound interesting. WxWidgets looks a lot like Windows API with classes. Here is a tutorial ending up with source code for a tetris game.

LLDB Debugger

I use the lldb debugger in the llvm toolchain which comes installed on Mac OS X.

# Load executable compiled with -g option. lldb Bin/Primpoly.exe (lldb) target create "Bin/Primpoly.exe" Current executable set to 'Bin/Primpoly.exe' (x86_64). # Set a breakpoint in the code.

Go to Python and download the latest version of Python from the site. Go to custom and make sure it installs into the correct directories on the system.

Windows On a Windows system, install into C:\Program Files\Python Go to Start/Control Panel/System/Advanced/Environment Variables and add the string ;C:\Python31; to the end of the path. For cygwin, in your Bash profile in your home directory, /cygdrive/c/cygwin/home/.bashrc, put PATH="/cygdrive/c/Python31:${PATH}" or else you can do a symbolic link, cd /usr/bin ; rm python ; ln -s /cygdrive/c/Python31/python3 python"

Mac or Linux Place code in your .bash_profile to set the path to Python 3.x Then run python -V to check the version is 3x and type quit() to exit. Keep the tutorial and library reference handy. Or better yet, download the whole set.

If you program LISP already, Python is very similar.

Common Lisp

My parser generator project is coded in Common Lisp.

Macs Download the install package for the binary from Steel Bank Common Lisp. Unpack and follow instructions.

$ sudo INSTALL_ROOT=/usr/local sh ... SBCL has been installed: binary /usr/local/bin/sbcl core and contribs in /usr/local/lib/sbcl/

You'll get a bare-bones command line REPL. Try running $ sbcl from the command line and try (car '(a b c)) and (cdr '(a b)) and (quit) For convenience, I load my LISP parser generator project files in the SBCL startup file .sbclrc

(load "LR(1)AndLALR(1)ParserGenerator.lsp") (load "LR(1)AndLALR(1)Parser.lsp") (test-parser-generator) (test-parser)

However, your life will be much easier if youw download and install Slime Unpack and install the slime directory in /Applications/slime then install this .emacs file in your home directory:

(setq inferior-lisp-program "/usr/local/bin/sbcl") (add-to-list 'load-path "/Applications/slime") (require 'slime) (slime-setup)

Vim, Ctags, Emacs, Slime, Steel Bank Common Lisp.

You should also install Emacs Invoke Emacs and with the command M-x slime go into Lisp interaction mode. Useful REPL commands are Control-c Control-p to move back one prompt, Control-c Control-n to move forward, Control-a and Control-e to go to beginning and end of the line, Control-x o to switch between buffers, Control-C Control-D d to lookup documentation for a symbol, and Control-X Control-S to exit emacs.

For LISP documentation online see

I've also used CLISP and XLISP.


  1. Mac or Windows On either Mac OS X or Windows, install Java from Oracle Java Downloads
  2. Mac Install Netbeans for Mac OS X
  3. Windows After installing Java, click on the downloaded executable file jdk-NuN-nb-N_N_N-win-ml.exe to install the Java SDK. This includes the Java runtime environment as well as the compiler (javac), interpreter (java), debugger (jdb), applet viewer (appletviewer). The SDK is installed into C:\Program Files\Java\jdkN.N.N_NN/bin and the NetBeans IDE is installed into C:\Program Files\netbeans-N.N.N. It will appear as an icon on the desktop.

    In Settings->System->Advanced->Environment Variables, under System Variables, edit the path to include ...;C:\Program Files\Java\jdkN.N.N_NN\bin;...

    Now open a DOS or Cygwin command window and test run the Java compiler, interpreter, and debugger javac -version, java -version, and jdb -version. You should get back version number N.N.N_NN

  4. Now that you're set up, begin programming by reading the introductory Java language tutorial Java Tutorial. For the GUI, read Java Swing Tutorial, and for reference the Java API.

Octave is a free MATLAB clone. On Macs you need to install gnuplot. Download the gnuplot source and unpack it into a directory. Run ./configure --with-readline=builtin, then run make and finally sudo make install.

Wise words from, In a nutshell, this is a problem with OSX itself. Apple chose to ship Leopard with an emulated libreadline package. But the emulation is incomplete, and programs that link against it expecting a "real" libreadline fail with erros like the ones you quote. I suggest complaining to Apple. They should hear from their users that their choice of libraries was not good. Meanwhile, your options are either (1) delete the broken libreadline that shipped with Leopard and replace it with the real gnu libreadline (2) tell gnuplot not to use libreadline at all ./configure --with-readline=builtin

Run from /Applications. It comes up in a terminal window. In the window, cd to your working directory containing your MATLAB .m files. Type the name of your MATLAB function or type the name of the .m file if you have just an inline main program. Plots will pop up in a separate window using the X11 windowing system.

VIM Programmer's Editor

Download gvim from Vim. I compile from source for my MacBookPro. Also install the Vim Tutorial Book, vimbook-OPL.pdf in the same directory under subdirectory /Notes. Don't forget the Vim User Manual, FAQ and download instructions.

In Ubuntu Linux, do

sudo apt-get install vim sudo apt-get install vim-gnome

To do file differences, load the first file, ignore whitespace with :diffopt=iwhite, then do :diffsplit <second file name> :diffupdate will resync if needed. Put my customized file .vimrc and also FunctionHeaderTemplate.txt etc into C:/Program Files/vim or ~ (Unix home directory). Here is my .vimrc

Lisp Files

When you right click on a file name with a .lsp extension, you should see Vim in the Open With list. If you can't see it, run regedit, go to HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Explorer/FileExts/ .lsp/OpenWithList. You'll see Names a, b, c, d, etc. Change one of them or add a new one with (for example) Name=b, Type=REG_SZ and Data=gvim.exe. Make sure Name=MRUList with Type=REG_SZ has Data=c in its list.

If you can't get gvim to open a *.lsp file in explorer when you click on the file name, run regedit, go to HKEY_CURRENT_USER/Software/Classes/Applications/gvim.exe create subdirectories /shell/open/command in command, let the name=(Default), Type=REG_SZ and the Data= "C:\Program Files\vim\vim71\gvim.exe" "%1" Now you should be able to associate *.lsp files with gvim.exe HKEY_CLASSES_ROOT/.lsp has Name=(Default), Type=REG_SZ, Data=Vim.Application.

C, C++ and CTags

Edit C:/Program Files/vim71/syntax/c.vim and add the keyword uint to the list of keywords beginning with int.

You should also install Exuberant ctags to make your programming life easier. Follow instructions on how to compile the source on Mac OS X. You may need to edit the makefile to set the C compiler and its compile and link flags properly. To use it, let's say your C++ source code is in /Sean/Project/SourceCode. Go up one directory and generate a tags file,

cd /Sean/Project
ctags -R

In VIM, do :set tags=./tags,tags,/Sean/Project/tags. Now, when you edit a C++ file in VIM, go to a function name and do Ctrl-] to zap to the definition of the function and Ctrl-T to get back. If there are duplicates, use :ts, e.g. :ts operator = shows a list of possibilities to pick.

C++ operators will cause trouble, so edit the tags file to eliminate spaces using :1,$s/operator /operator/g to convert tags such as "operator +=" to "operator+=" for example. Also set the flag at the top of the ctags file to indicate UNSORTED, i.e. don't use binary search. To jump, highlight operator+= with the mouse, then hit Ctrl-], or use :tag operator+=. If there is ambiguity, use the command :ts operator+= and select the tag you wish to jump to.

Perl Files

To properly syntax-color Perl files with the *.prl file name extension, edit C:/Program Files/vim71/syntax/perl.vim and add *.prl to the lines below:

" Perl
if has("fname_case")
  au BufNewFile,BufRead *.pl,*.PL,*.prl call FTCheck_pl()
  au BufNewFile,BufRead *.pl,*.prl call FTCheck_pl()
