f2py build with mkl lapack
Hi I'm trying to use fortran wrapper f2py with intel's mkl following is my command LIB='-L/opt/intel/Compiler/11.1/064/mkl/lib/em64t/ -lguide -lpthread -lmkl_core -lmkl_intel_lp64 -lmkl_sequential' INC=-I/opt/intel/Compiler/11.1/064/mkl/include f2py --fcompiler=intelem $INC $LIB -m solveLE -c solveLE2.f solveLE2.f is simple fortran code using lapack's linear equation solver SGESV ============= CALL SGESV(N, NRHS, A, LDA, IPIV, B, LDB, INFO) ============= When i use the command, compile was done. But when I use the solveLE.so, I received following error massage ================== $python test.py python: symbol lookup error: /opt/intel/Compiler/11.1/064/mkl/lib/em64t/libmkl_lapack.so: undefined symbol: mkl_lapack_sgetrf ================== I think "mkl_lapack_sgetrf" is defined in -lmkl_sequential. I don't know what should I do. Any help would be greatly appreciated! Sunghyun Kim Ph.D. Candidate Theoretical Condensed Matter Physics Group.

Linking order matters: if A needs B, A should appear before B, so -lpthread/-lguide should be at the end, mkl_intel_lp64 before mkl_core, and mkl_sequential in front of that. See the MKL manual for more details, David

I think "mkl_lapack_sgetrf" is defined in -lmkl_sequential.
I don't know what should I do.
Any help would be greatly appreciated!

See the MKL manual for more details,
You may also want to consult the MKL Link Line Advsior [1], which in your case recommends an ordering like: -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lpthread -lm [1]: http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor -Brad
thank you for your help I tried following orders and many combinations... ===================== LIB='-L/opt/intel/Compiler/11.1/064/mkl/lib/em64t/ -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lpthread -lm' LIB='-L/opt/intel/Compiler/11.1/064/mkl/lib/em64t/ -lmkl_solver_lp64_sequential -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lpthread -lm' ==================== but I still got following massage ================ undefined symbol: mkl_lapack_sgetrf ================ Sunghyun Kim Ph.D. Candidate Theoretical Condensed Matter Physics Group.
