Hi, all of a sudden I cannot compile using gfortran on my 64 bit RHEL 4.0 machine ?!

I have been compiling in the following way for as logn as I can remember:

gfortran -O3 -o d2dump d2dump.f90

but now I get the following message:

ld: crtbegin.o: No such file: No such file or directory

d2dump.f90 is a very simple fortran code of a few lines, in fact written in f77. It compiles without problem using g77 instead of gfortran (I have to change the filename to d2dump.f first.)and then I can run ./d2dump.

This problem occured out of the blue yesterday. My suspcion is that some new options must have been installed, because this problem appear soon after I had run up2date. (But it could be something else.)

Can any one advise?

Cheers

Really I have no idea, but here's a dumb question: Is there, in fact, a crtbegin.o file anywhere in the filesystem? A crtbegin.* something else? Maybe your update erased old compiled object files ( a not uncommon event ) and you have to remake them. Just a suggestion
