What is the makefile option to debug mixed C and CPP programs?

Question

My project is developed in C and call functions written in CPP. With the following option: OPTS = -g I can debug only my C programs. How to allow gdb debugger to step into the CPP programs.

Best,

`-g` should work for C++ too. We'll need more details (aka a [mcve]). — HolyBlackCat, Oct 03 '21 at 12:07
`OPTS` is not part of the implicit rules of gmake. What is your compile rule for C? What is your compile rule for C++? — Eljay, Oct 03 '21 at 12:18

With GCC and Clang compilers both C flags and C++ flags are separate, I suspect your -g is only being passed to the c files and not the cpp files. Ensure you set both CFLAGS and CXXFLAGS with -g. See here for a example https://stackoverflow.com/a/23407800/2729443
