Hi ! I am using a Mac OS X 10.6.8. I have downloaded GNU Pascal for Mac Os from http://www.microbizz.nl/gpc.html together with Apple’s Mac OS X assembler and linker (cctools-576) (binary). I got the following error : gp test.pas /usr/bin/ld: can't locate file for: -lcrt1.o collect2: ld returned 1 exit status I should be happy to know how to "fix" this "problem". Thanks in advance for help. Baudouin
