configure: WARNING: You are running configure with the compiler (clang) set to a different value from that used by gnustep-make (x86_64-pc-linux-gnu-g++).  To avoid conflicts/problems, reconfigure/reinstall gnustep-make to use CXX=clang or run the gnustep-base configure again with your CXX environment variable set to x86_64-pc-linux-gnu-g++

This error is telling you that the gnustep-base library was built using one form of exception handling, but that the gnustep-make package you are using is building code to use the other form of exception handling ... with the consequence that exception handling would be broken in the program you are building. So,
      somehow your gnustep-base and gnustep-make package are incompatible, and you need to replace one of them with a version configured to match the other."
