Re: installing gcc various versions

[Ivan Marin <ispmarin@gmail.com>]

Usually the problem is not the compiler, but the link line. Check if
the paths are ok, and if the libraries are really there. Also, check
if there are static (.a) and shared (.so) libraries on the path.


LIBS= -L/opt/acml4.2.0/gfortran64_mp_int64/lib -lacml_mv -lgfortran -lpthread

Also, the LIB and the LD_LIBRARY_PATH are a little different:

/opt/acml4.2.0/gfortran64_mp_int64/lib
/opt/acml4.2.0/gfortran64_mp/lib

Is these right?

Cheers,

Ivan
