static link problem (mkl 6.1, ic 8.1, Itanium)

I am trying to build astatically linked code using the above to test how it runs on a different machine where ic 8.1 is not available. When linking with
-L/opt/intel/mkl/lib/64 -lmkl_ipf -lmkl_lapack -lguide -lm -lpthread -static -static-libcxa
the compiler retruns me
/opt/intel/mkl/lib/64/libmkl_lapack.a(dgetrf_omp.o): In function `_dgetrf_omp_269__par_loop0':
dgetrf_omp.o(.text+0x1442): undefined reference to `dtrsm'
/opt/intel/mkl/lib/64/libmkl_lapack.a(dgetrf_omp.o): In function `_dgetrf_omp_319__par_loop1':
dgetrf_omp.o(.text+0x2002): undefined reference to `dtrsm'

What's wrong?Where does OpenMP come from?
There isneither -openmp nor -parallel in the command.

Thanks to all in advance.

Are you raising 3 or more issues here? I don't see any problem demonstrated, other than your backwards order of library references. As I'm sure you read, mkl itself is build with -openmp.

The _only_ issue I have is how to build a statically linked code using IC 8.x and MKL (i.e. independent portable binary)

Are you suggesting I should be using -static before mkl? Apart from that my order is exactly the same as in MKL 6.1 tech user notes.

So you are saying there are no two MKLs with and without -openmp.
There's only one and this is the reason why -lpthread must be _always_ used to link with MKL. Therefore I might havethe stackproblem because of the Linuxthreads limitations.
But I still should be able to build statically, shouldn't I?

dgetrf is an LAPACK function that calls dtrsm (a function in the BLAS). So you libmkl_ipf should come after libmkl_lapack. If you got this from the tech user notes you should probably submit a bug.


MKL is built with openmp and the function calls generated by this can be resolved in libguide which you already have on your link line.
