Hi All,
I am trying to configure a software with intel MKL 2015.
I had used link lines(inplicit,explicit linking) : -liomp5 -lpthread -lm -ldl , as well as -L${MKLROOT}/lib/intel64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm -ldl
and -mkl=parallel , -I${MKLROOT}/include.
i am currently stuck with following configure error(implicit linking MKL):
checking for MKL BLAS configure:21747: mpiicpc -o conftest -std=c99 -fms-extensions -funsigned-char -pedantic -W -Wall -Wshadow -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Wunused -Wfloat-equal -fPIC -mkl=parallel -D_POSIX_SOURCE -DNDEBUG -O -Wl,-export-dynamic -L conftest.c -liomp5 -lpthread -lm -ldl icpc: command line warning #10006: ignoring unknown option '-Wnested-externs' icpc: warning #10315: specifying -lm before files may supersede the Intel(R) math library and affect performance /usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' configure:21747: $? = 1 configure: failed program was: ..........| #define HAVE_LIBXML_PARSER_H 1 | #define HAVE_LIBXML2 1 | /* end confdefs.h. */ | #include <mkl_blas.h> | int | main () | { | cblas_ddot(0, 0, 0, 0, 0); | ; | return 0; | } configure:21757: result: no configure:21979: error: in `/home/user/CODESATURNE/code_saturne-4.0.6': configure:21981: error: BLAS support is requested, but test for BLAS failed!

also the logs with explicir MKL linking:

Any help/hint will be very useful.
