How to configure toolchains to generate build files for unit tests?

Question

Hi There, 
 
 I am trying to generate build files for unit tests according to nRF5 SDK for Mesh v5.0.0. It could succeed. I try everything, it still cannot work. (In windows 10) 
 
 1. Enter "cmake -G Ninja -DBUILD_HOST=ON -DCMAKE_BUILD_TYPE=Debug .." 
 CMake Error at C:/Program Files/CMake/share/cmake-3.21/Modules/CMakeTestCCompiler.cmake:66 (message): The C compiler 
 "C:/MinGW/bin/gcc.exe" 
 is not able to compile a simple test program. 
 It fails with the following output: 
 Change Dir: C:/BLE/Mesh/sdk/blecom/nrf5_SDK_for_Mesh_v5.0.0_src/build_host/CMakeFiles/CMakeTmp 
 Run Build Command(s):C:/ProgramData/chocolatey/bin/ninja.exe cmTC_e3c7c && [1/2] Building C object CMakeFiles\cmTC_e3c7c.dir	estCCompiler.c.obj FAILED: CMakeFiles/cmTC_e3c7c.dir/testCCompiler.c.obj C:\MinGW\bin\gcc.exe --std=gnu99 -ffunction-sections -fdata-sections -fno-strict-aliasing -fno-builtin --short-enums -m32 -Wall -Wextra -Werror=implicit-function-declaration -Wno-format -Wno-unused-parameter -Wno-missing-field-initializers -Wno-expansion-to-defined -mno-ms-bitfields -o CMakeFiles\cmTC_e3c7c.dir	estCCompiler.c.obj -c C:\BLE\Mesh\sdk\blecom

 CMake will not be able to correctly generate this project. Call Stack (most recent call first): CMakeLists.txt:75 (enable_language);

Hi, 
 I assume that you have successfully installed the dependencies listed under Optional: Additional tools for building unit tests (host) , and that you are following the instructions under Generating build files for unit tests (host) . 
 I do not get similar errors when trying this in my end, so it is probably because of a difference between our systems. 
 From what terminal are you issuing the build command? (cmd.exe? git bash? WSL shell?) From what path are you issuing the build command? Is what you printed the full printout, or were there more printed to the console? What is your version of MinGW? Did you "git checkout 7cc41dd" from the CMock directory, in order to use the same version of CMock as in the tool listing?
