I'm trying to compile a program on Mac OSX Catalina, and I'm running into the following error:
[USER:~/Seisan/PRO]$make all
cd ../LIB; /Library/Developer/CommandLineTools/usr/bin/make all; cd ../PRO

When I run which gcc, I get /usr/local/bin/gcc. I have updated Xcode by doing: xcode-select --install. I have XQuartz installed. What could be the issue? Thanks for the help.
