Re: [Tinycc-devel] Unable to find include directories by tcc on Catalina

[Peng Yu]

I reinstalled CommandLineTools by the following command. clang and gcc
became these. But clang still does not work. Is there a way to let tcc
install use gcc instead of clang?

$ sudo rm -rf /Library/Developer/CommandLineTools
$ xcode-select --install
$ clang --version
Apple clang version 12.0.0 (clang-1200.0.32.29)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
$ gcc --version
Configured with:
--prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple clang version 12.0.0 (clang-1200.0.32.28)

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
$ which gcc
/Library/Developer/CommandLineTools/usr/bin/gcc
$ which clang

$ gcc -E - <<< '#include <stdlib.h>' > /dev/null || echo "$?"
$ clang -E - <<< '#include <stdlib.h>' > /dev/null || echo "$?"
