An exercise (from Accelerated C++ Chapter 4) that I have come across recently requires me to partition the program. i.e. instead of writing the entire program in one main.cpp file, I need to split to over multiple C++ source files (with extension .cpp) and header files (with extension .h).
To add C++ source (.cpp) or header (.h) files, do the followings in Code::Block.
- File –> New –> File
- Select C/C++ source (or C/C++ header)
- Click Go
- Click “next”
- Select C++, then “next”
- Set the file path of the C++ source file accordingly (e.g. same location as the main.cpp file). Name the file to xxx.cpp (or xxx.h)
- To make the source file compilable, select “Debug” and “Release” under the Add file option. (If forgotten this step, see the “How to set build target” section below)
- Now the source file should appear under Workspace –> ProjectName –> Sources
- To compile the file, simply right-click the filename, and click “Build file”.
How to set build target
Assuming we have forgotten to perform step 7 above (or for whatever other reasons), we can always set that target again to enable smooth file build.
- Right-click the project name
- Build targets tab
- Under the Build target files section in bottom right, check the (currently not checked) files, click OK.
- Next time when you right-click the file and build file, Code::Block should build the file accordingly.
