After CMake update from 3.7.2 to 3.21.0, the try compile a simple test program is broken

I have a working cmake (3.7.2) with toolchain file for my gnu based cross-compiler. After update cmake to 3.21.0 it is not able to compile a simple test program.

Output:

-- The C compiler identification is GNU 4.6.4
-- The CXX compiler identification is GNU 4.6.4
-- Detecting C compiler ABI info
CMake Error: Generator: execution of make failed. Make command was:  -f Makefile cmTC_79efc/fast &&

  The C compiler

    '<compiler-root-path>/tricore/v4.6.6.1/bin/tricore-gcc.exe'

  is not able to compile a simple test program.

  It fails with the following output:

  CMake will not be able to correctly generate this project.

I have search a long time for this problem, but i don't find a solution.
I have found some solution which are nearly the same, they describe what is to do if try_compile will not work.
But I have a working toolchain-file (and so on) for V3.7.2 but the same will not work with V3.21.0.
Also i have not found that something must be changed at the toolchain-file while updateing.

Thanks for all helpful answers.

Solution

  • I found the problem, in my toolchain-file there is the line
    SET(CMAKE_MAKE_PROGRAM "${COMPILER_ROOT_DIR}/bin/make.exe")
    and it must be
    SET(CMAKE_MAKE_PROGRAM "${COMPILER_ROOT_DIR}/bin/make.exe" CACHE INTERNAL "")
    For whatever reason the first one will work in V3.7.2 and not in V3.21.0.
    The second works in both
