make[2]: *** [CMakeFiles/path_planning.dir/src/main.cpp.o] Error 1
make[1]: *** [CMakeFiles/path_planning.dir/all] Error 2
make: *** [all] Error 2

How do I fix these fatal errors? I installed cmake using brew, and these errors started appearing when I upgraded to a new Mac.

Does this have something to do with the preferences in cmake itself?

Answer 1

I see the same error in npm install hummus or when I try clang++ test.cpp for

      #include <cstdint>

      int main(int argc, char **argv) {
         return 0;
      } 

To compile, add the Mac SDK to the include paths:

clang++ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk test.cpp
