Runit runs fine on MacOS, but the nix package definition declares that it only works on Linux.
I figured I could modify it to allow for the MacOS directions (which I did follow and worked fine).

Compilation, however, fails upon trying to compile tryuwtmpx.c, shown below:

The output of cc-conf is just cc.
cc --version puts out
clang version 7.1.0 (tags/RELEASE_710/final)
Target: x86_64-apple-darwin19.4.0
Thread model: posix
InstalledDir: /nix/store/r9rg4hqk1lga7w3dcxnkdg6c88cm8lfr-clang-7.1.0/bin
By default, runit uses gcc to compile. gcc --version puts out
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin19.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
So I guess my question is what exactly is the difference between cc and gcc here? Is it just a version issue? is it the IncludeDir flag on gcc? How would I go about fixing this?
I work on a project that utilizes runit to run it, and am slowly trying to build out a nix-shell to manage it. Any tips or assistance would be greatly appreciated!
