ld: warning: ignoring duplicate libraries: '-lSystem'
ld: library 'System' not found
collect2: error: ld returned 1 exit status
gprbuild: link of main.adb failed

This happens when gprbuild starts linking. i believe this is a macos related issue.

Please say

• what version of macOS you're using, and which architecture (Apple (M1, etc) or Intel silicon)
• what version of GNAT you're using, and where you got it from

and I'll try to help.
