ifort linking error

[simon932]

Dear all,

I am getting the following error at the final linking step for a fortran90 program:

This is on CentOS 6.4 and I am using the following version of ifortran:

ifort (IFORT) 12.1.6 20120821

I am quite beginner at this, and I was hoping someone more experienced could point me to what I might be doing wrong here.

Many thanks,

Simon

See this?

/cm/shared/apps/intel-cluster-runtime/3.6/composer_xe_2013_sp1.0.080/compiler/lib/intel64/libifcoremt.a(for_init.o):for_init.c:

That tells me you have at least some 14.0 libraries in your linking path. You are getting a mix of 14.0 and 12.1 libraries and this causes the link errors. Check your build environment and make sure you are "source"ing the correct ifortvars.sh file.

Thank you, indeed executing 'source /cm/shared/apps/intel/composer_xe/2011_sp1.12.361/bin/ifortvars.sh intel64' before compiling solved my problem!
