Can not build due to missing libgmp on macOS Monterey 12.5.1

[chiro-hiro]

Build error

error: linking with `cc` failed: exit status: 1
[....]
  = note: ld: library not found for -lgmp
          clang: error: linker command failed with exit code 1 (use -v to see invocation)
          

error: could not compile `ecdsa-mpc` due to previous error

How to fix?

Install GMP with homebrew:

brew install gmp

Make sure gmp linked:

brew link --force gmp

Create file .cargo/config in source code folder:

[target.x86_64-apple-darwin]
rustflags = [
  "-L", "/opt/homebrew/lib",
  "-L", "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib",
  "-C", "link-arg=-undefined",
  "-C", "link-arg=dynamic_lookup",
]

[target.aarch64-apple-darwin]
rustflags = [
  "-L", "/opt/homebrew/lib",
  "-L", "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib",
  "-C", "link-arg=-undefined",
  "-C", "link-arg=dynamic_lookup",
]

These flags was used to guide rustc to look up libraries from homebrew. I'm prefer an official patch.

I recall that when I had this problem on new Mac Apple Silicon , I installed the lib:

brew install gmp
I have checked what had been installed:
brew list gmp

/opt/homebrew/Cellar/gmp/6.2.1_1/include/ (2 files)
/opt/homebrew/Cellar/gmp/6.2.1_1/lib/libgmp.10.dylib
/opt/homebrew/Cellar/gmp/6.2.1_1/lib/libgmpxx.4.dylib
/opt/homebrew/Cellar/gmp/6.2.1_1/lib/pkgconfig/ (2 files)
/opt/homebrew/Cellar/gmp/6.2.1_1/lib/ (4 other files)
/opt/homebrew/Cellar/gmp/6.2.1_1/share/info/ (3 files)

and then I found that required library files already have symlinks in /opt/homebrew/lib, so that adding

export LIBRARY_PATH=/opt/homebrew/lib

to .profile ( or .zprofile ) solved the issue

Adding a .cargo/config could solve this problem for everyone. We just needed to figure out what is the different between arch and OS version?.
