Title: Observations on using CodeBlocks_wx33_64.cbp and friends
Post by: everSome on August 20, 2025, 09:23:52 pm

I've generalized my version of the *_wx33_64.cbp files to the form used in src/CodeBlocks_wx33_64.cbp where in the project wide compiler options begin with

Code

			<Add option="-Wall" />
			<Add option="-m64" />
			<Add option="$(#CB_RELEASE_TYPE)" />

with one caveat. I removed the option

Code

			<Add option="$(#CB_CPP_STD)" />

from all the target compiler option lists and moved it into the Project compiler list so that I now use the combination:

Code

			<Add option="-Wall" />
			<Add option="-m64" />
			<Add option="$(#CB_CPP_STD)" />
			<Add option="$(#CB_RELEASE_TYPE)" />

Doing it this way allows one to define CB_CPP_STD as "-std=gnu17 -std=gnu++20". This works when using a variant of CompilerMINGW as it uses the specifications CFlags and CPPFlags in

Code

src\plugins\compilergcc\resources\compilers\options_common_sort.xml

to determine what is inappropriate for C or C++ compilations.

The current lists therein are sufficient for distinguishing where it is
appropriate to use "-std=gnu17" versus "-std=gnu++20".

Nonetheless, these CFlags and CPPFlags specs could use a minor update. Seems both gcc and clang support the new CFlags, but of the as yet future C++ standard, g++ uses std=c++26 -std=gnu++26 where clang++ uses -std=c++2c -std=gnu++2c
