Error: “no member named 'uint8_t' in the global namespace” on MacOS

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?

回答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
