first time user ---makefile linking problems

ronald_haynes — Thu, 02 Mar 2006 23:54:42 GMT

Hi everyone, I have installed mkl 8.0.1. I have the intel fortran compiler installed (and working). I have included both the makefile and partial output below.

The environment variable MKLPATH is set in the shell.

Any help would be greatly appreciated.

Thanks,
R Haynes

Here is the makefile:
drive: driver.o odesolve.o mynewton_nor.o xfdjac.o xfdjac1.o
ifort -o drive ${MKLPATH}/libmkl_lapack.a ${MKLPATH}/libmkl_solver.a
${MKLPATH}/libguide.a -lpthread driver.o odesolve.o mynewton_nor.o
xfdjac.o xfdjac1.o
driver.o: driver.f
ifort -c driver.f

odesolve.o: odesolve.f
ifort -c odesolve.f

mynewton_nor.o: mynewton_nor.f
ifort -c mynewton_nor.f

xfdjac.o: xfdjac.f
ifort -c xfdjac.f

xfdjac1.o: xfdjac1.f
ifort -c xfdjac1.f

Here is the output:

ifort -o drive /opt/intel/mkl/8.0.1/lib/32/libmkl_lapack.a /opt/intel/mkl/8.0.1/lib/32/libmkl_solver.a

You must arrange so that the library searches occur after your .o files are loaded. Usually, this is done in something like the following fashion:
ifort -L/opt/intel/mkl/8.0.1/lib/32/ -openmp *.o -lmkl_lapack -lmkl_solver

Hi, thanks for the swift reponse. So I changed the makefile to:

drive: driver.o odesolve.o mynewton_nor.o xfdjac.o xfdjac1.o
ifort -L/opt/intel/mkl/8.0.1/lib/32/
driver.o odesolve.o mynewton_nor.o xfdjac.o xfdjac1.o
-lmkl_lapack -lmkl_solver -o drive

(everything else unchanged)
and make now gives the output below--- any thoughts?

$make

ifort -o drive -L/opt/intel/mkl/8.0.1/lib/32/

You didn't specify -lguide or -lpthread, which would be taken care of by -openmp or -parallel options to ifort. It looks like only mkl_lapack was searched successfully, as you are missing a bunch of references which the other mkl library should take care of. I haven't used 32-bit 8.0.1 myself.

Re: first time user ---makefile linking problems

After some discussion with members of the compiler team, a concensus was reached that you were correct in not using the -L and -l method for linking MKL. However, you should link the libguide provided with the compiler, not the one provided with MKL, unless you are using an old compiler version, where the libguide is older than the one provided with MKL.

ifort -o drive -i-static -openmp

driver.o odesolve.o mynewton_nor.o

xfdjac.o xfdjac1.o

${MKLPATH}/libmkl_lapack.a ${MKLPATH}/libmkl_solver.a

The -i-static option specifies linking against the libguide.a and other static libraries provided with the compiler. The function of -openmp at link time is to add -lguide -lpthread.

mkl_lapack depends from main MKL library (libmkl_ia32.a/libmkl.so). You should include libmkl_ia32.a (or libmkl.so) into your link line after including mkl_lapack library.
