ld: file not found: /usr/lib/crt1.o

Question

When trying to compile Fortran using PGI on Mac OS X Sierra, I get the error

ld: file not found: /usr/lib/crt1.o

I found a workaround for older Mac OS X versions (http://www.pgroup.com/userforum/viewtopic.php?t=4578)

sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/lib/crt1.o /usr/lib/crt1.o 

However, with Sierra, System Integrity Protection prevents writing in /usr/bin. How can I solve this problem?

I tried linking into /usr/local/bin/ (which is permitted), but then, how can I make sure the compiler searches for library in that path?

Answer 1

Installing just the Command Line Tools for Mac OS X solved the problem. Do this in your terminal:

xcode-select --install

Answer 2

Installing Lazarus on MacOS X : worked for me
