New description:

 When I was trying to install minetest it's dependency irrlichtmt failed to
 build. The log contains all the details about what went wrong. Some of the
 errors include:

 {{{

 irrlicht-1.9.0mt10/include/irrString.h:955:26: error: use of undeclared
 identifier 'mbstowcs'
 :info:build                 const size_t written =
 mbstowcs(&destination[0], source, (size_t)sourceSize);

 irrlicht-1.9.0mt10/include/irrString.h:1001:52: error: cannot initialize a
 parameter of type 'wchar_t' with an lvalue of type 'const wchar_t *'
 :info:build                 const size_t written =
 wcstombs(&destination[0], source, destination.size());
 :info:build
 ^~~~~~
 :info:build /usr/include/wchar.h:148:42: note: passing argument to
 parameter here
 :info:build size_t  wcrtomb(char * __restrict, wchar_t, mbstate_t *
 __restrict);
 }}}

 Currently the irrlichtmt port being used is version 1.9.0mt10. The newest
 version is irrlicht-1.9.0mt14. I downloaded this version and it was able
 to build it successfully. I just had to specify the compiler to use. This
 is the command I used to make the cmake step work:


 {{{
 cmake . -DBUILD_SHARED_LIBS=OFF -D CMAKE_C_COMPILER=clang-mp-16 -D
 CMAKE_CXX_COMPILER=clang++-mp-16
 }}}

 I picked clang-mp-16 because it was already on my system. I don't know if
 an older version would work. From the error message I saw it looks like a
 compiler that supports CXX17 should work.

 This is where I downloaded irrlichtmt:
