Cargo build fails ld: library not found for -lmcrypt on Apple sillicon

I have installed mcrypt on my apple m1 chip using a brew and pecl

$ which mcrypt
/opt/homebrew/bin/mcrypt

$ pecl list
Installed packages, channel pecl.php.net:
=========================================
Package Version State
mcrypt  1.0.4   stable

However, when I build my personal Rust project locally, it fails to link libraries as follows. Is there some configuration that I am doing wrong or is there a parameter that I need to specify during the build?

= note: ld: library not found for -lmcrypt
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

Solution

  • I solved this issue. Just needed to export the $LIBRARY_PATH explicitly by typing:

    export LIBRARY_PATH=$LIBRARY_PATH:/opt/homebrew/opt/mcrypt/lib/
