[gmx-users] Error: C compiler cannot create executables

Hi,

This is the important part:

The configure script tries to compile a really trivial program, without 
any options whatsoever (just cc filename.c), and your compiler says:

> /usr/bin/ld: cannot open crt1.o: No such file or directory

Both gcc 2.95 and GNU libc version 1 are pretty old, but they should 
work with gromacs, so something must be misconfigured on your systems. 
Check the documentation/support for your OS and make sure you can 
compile a C program such as:

int
main()
{
;
return 0;
}



Cheers,

Erik
