compiler errors after upgrade to Leopard

[pboz39]

Hi,

I'm a beginning programmer focused on Fortran for the moment. I had gfortran up and running on my imac (Intel Core2 duo) until I upgraded to Leopard last weekend. Now every time I try to run the compiler (even with scripts that I know are good) I get an error that says :

/usr/bin/ld: warning unknown -macosx_version_min parameter value: 10.5.6 ignored (using 10.4)
/usr/bin/ld: can't locate file for: -lcrt1.10.5.o
collect2: ld returned 1 exit status

Based on the error it's clear that something didn't transfer from Tiger to Leopard, but I've tried reinstalling xCode and the gnu compiler, and the gfortran for xcode plugin, and still get the same error. I'd appreciate any suggestions.

Thanks for your time.

SDK may still be set to 10.4. Also set the deployment target to 10.5.
