Ok, I did not acquired to compile gromacs with intel yet, but now I'm also facing problems with PGI compilers (which also has the extra problem of needin to be redownloaded soon).
Just in case someone asks: I'm trying to benchmark gromacs in A64s with different compilers. ;)
Well, PGI is dieing here:

I googled this kind of error, but it's only reported to LAM... in that case, they basically recomend to pass the -Wl flag to the linker.
Did anybody here faced this problem before? How it was solved? And exactly how culd I pas that extra flag just to the linker (tried straight the LDFLAGS, then the ./configure does not find that the compiler can produce executables... :p )?
Thanks you all for all the help. Promisse to send the results of the benchs to here when they are finished. :)
Thanks again,
Jones

The single precision FFTW3 library. You probably didn't include "--
enable-float". Go through the detailed instructions at
