This is a minimal example of how a custom CMake toolchain file can be used to compile projects that use the cc65 compiler/assembler.
In this example there are two assembly source files (source1.s and
source2.s), a header file (header1.inc) that is included by one of the
source files, and a linker configuration file (linker.cfg). The files can be
found in the src directory. A change in any of these files will trigger
recompilation.
More source files, custom build rules, etc., can be specified in
CMakeLists.txt. The build outputs a binary file
cc65_toolchain_example.bin in the build directory.
You can probably find these from your favorite package manager, or you can install them manually.
- cc65
- CMake
- Ninja
The dependency handling doesn't work with the Makefile generator for some reason, so I recommend using Ninja.
If you're on Windows, the build.sh script won't work (it might work in MinGW
and definitely should work on WSL, though). In that case you can run the
commands manually, or make a batch script for cmd.
Simply run ./build.sh to build the project. Remove the build directory if
you want a clean build.
