I still got the libiomp error. <BR /><BR />When I use -openmp in my flag, do I have to link with libiomp.so and libpthread?<BR /><BR />Regards<BR />shizoom Tue, 01 Mar 2011 15:14:52 GMT https://community.intel.com/t5/Intel-Fortran-Compiler/libiomp-so/m-p/753286#M9061 swang 2011-03-01T15:14:52Z https://community.intel.com/t5/Intel-Fortran-Compiler/libiomp-so/m-p/753287#M9062 -openmp sets -liomp5 -lpthread automatically. As the default is to link against .so, you will need the LD_LIBRARY_PATH setting (which is set up by sourceing the compilervars script).
