I was running a bundle install on a rails application and was receiving a failure when attempting to install mysql2:
make "DESTDIR=" compiling client.c compiling infile.c compiling mysql2_ext.c compiling result.c compiling statement.c linking shared-object mysql2/mysql2.bundle ld: library not found for -lssl clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [mysql2.bundle] Error 1 make failed, exit code 2
The issue turned out to be missing headers on OSX, resolved by installing the pkg located here:
To fix this, navigate to this location, open a finder window, and run the pkg file located there:
cd /Library/Developer/CommandLineTools/Packages/ open .
And run macOS_SDK_headers_for_macOS_10.14.pkg.
