I tried the available link line advisor on Intel Software Network but did not succeed up to now to write correctly the linking command lines. With: $MKLPATH/libmkl_solver_sequential.a Wl,--start-group $MKLPATH/libmkl_intel.a $MKLPATH/libmkl_sequential.a $MKLPATH/libmkl_core.a -Wl,--end-group -lpthread the answer is (of course !) that dsyev ... are undefined references. Question : Where do I have to add the Lapack libraries ? In which order (before the group { }, after or in between ?) I am not a developper but only a base user of programming; any suggestion or receipe will be fruitful.

Can you provide your full link line? What is the value of $MKLPATH or at least the last bit of it? Could you provide the full output of the linker with all error messages?<BR /><BR />Thanks,<BR />Todd<BR /> Fri, 21 May 2010 16:12:55 GMT

I had forgotten to invoke the link with lapack and blas libraries ! (the = = sign for the load command was an error in the rewriting of the corresponding command line of my Makefile in the letter I sent you) It works now with: LIBS= -lmkl_solver_sequential \ -lmkl_lapack95 \ -lmkl_blas95 \ -lmkl_intel \ -lmkl_sequential \ -lmkl_core Thank you for your help Regards JLouis Bocquet Thu, 03 Jun 2010 14:18:15 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/linking-with-MKL-10-2-5-035-and-Lapack-for-Linux/m-p/815373#M4284 jlbocquet 2010-06-03T14:18:15Z
