Re: [Condor-users] condor_compile and lapack

[Hermann Zellner <Hermann1.Zellner@xxxxxxxxxxxxxxxxxxxxxx>]

Junaid,
I set the environment-variables of the condor_compile-skript manually
and tried to compile without the keyword condor_compile but with
the  libraries I got as you mentioned. Explicitly I added

condor_rt0.o libcondorzsyscall.a libz.a -lgcc libcomp_libstdc++.a
libcomp_libgcc.a libcomp_libgcc_eh.a

to my gcc command. But I got the same error. So I think the problem is
not related to the condor_compile-skript, but to the modified linker or
to the condor-libraries which are linked. Or did I miss a library?

I'm using gcc-3.3.5 and lapack 3.0. Has anyone succeeded to
condor_compile a program using lapack?

Thanks
Hermann Zellner
