Support using ccache when building gengetopt and ragel #732

Closed jeshwanthreddy13 closed 5 months ago

jeshwanthreddy13 commented 5 months ago

Fixes #639

Implemented ccache support when building gengetopt and ragel in file 'build-3rdparty.py'.
Added 'CC' and 'CXX' paramters when executing './configure' so as to inject 'ccache' when '--compiler-launcher=ccache' is used.

Additional Notes:

Added a new function "detect_compiler_presence" for detecting if a particular compiler is present or not.
Respective 'C' and 'C++' compilers are added to CC and CXX respectively by checking if the specific compilers can be executed.
Compiler launcher is added in 'CC' and 'CXX' only if the parameter is passed during build.

Hi!

Please take a look at the part of task about cross-compilation. We can't just use CC and CXX because they're set to cross-compiler, not native compiler.

Okay, so we need to make sure that CC and CXX are always passed with native compilers instead of the cross compilers for ragel and gengetopt?

gavv commented 5 months ago

Yes, because they are build tools running during build.
