1. Compilers, Make and SubVersion
UNIX/LINUX Tool Chain
Compilers, Make and SubVersion

2. Introduction As Software Engineers we need several things
Competency in the OS commands
Ability to create and manipulate text files
Compilers
Make
Version control
This presentation is about the last three of these

3. Execution A command that is typed must be on the path
The installation of most commands puts the executable on the path
The output of a compiler is not usually on the path
So to test X we must specify ./X
This directs to the current directory

4. Compilers There are two standard GNU compilers
gcc is the C compiler
g++ is the C++ compiler
The default behavior is to create an executable called a.out
This will be executed with ./a.out
See next page

6. Compile Options -c – compile only -o file – output file name
Many others as well
Most of these we will not need

7. Make Make was invented on a UNIX system We used GNU make on Windows
Not too much new here
The windows make needed more path information since a Windows program may execute things not on the path

8. SubVersion Commands
Our approach previously used a Windows File Explorer plugin
None of that anymore
Now we have to use the console SubVersion commands
There is only one command: svn
It is the options that make it do different things

9. SVN Options svn checkout url svn update url svn add url svn delete url
Checkout can be abbreviated co
svn update url
Update can be abbreviated up
svn add url
Announces the SubVersion a new file to be added
Must be followed by a commit
svn delete url
Also requires a delete
svn commit url
Commit abbreviation ci

10. SVN URL In the previous screen the URLs refers to the repository
This may be either:
svn://…
For example either of these: svn checkout cppunit-code svn checkout svn://svn.code.sf.net/p/cppunit/code/trunk cppunit-code

11. Finally We should now be ready for a project on UNIX
Then we will be real software engineers
