GCC and MKL come from

GCC and MKL come from different vendors, and you need to follow the standard conventions of Unix/Linux in order to use them together. You need to specify (i) (using the -I option) the directory containing the MKL header files, (ii) (using the -L option) the directory containing the MKL libraries, and (iii) (using the -l options) the specific MKL libraries to link. A convenient tool to help you with these options is the MKL Link Line Advisor, available at https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/ .

Prash,

Prash, You need to copy the example code /opt/intel/composer_xe_2013_sp1.0.080/mkl/examples/spblasc/source to your directory to edit. For security consideration, the original file can not be changed. For the compiling error, You needs to add the include path for that file: /opt/intel/composer_xe_2013_sp1/mkl/include/ thanks, Chao

hi.,

thanks for your respons mecej4 and Chao Y (Intel).

even I tried both the methods the same error is still existing. i guess the error may be I have set some path variables.

and I also tried with includeing the path in program

#include " /opt/intel/composer_xe_2013_sp1.0.080/mkl/include/mkl_types.h"

and i got an error:

cspblas_dcsr.c: In function ‘main’:
cspblas_dcsr.c:191:9: warning: excess elements in array initializer [enabled by default]
cspblas_dcsr.c:191:9: warning: (near initialization for ‘values’) [enabled by default]

so plz help to sort out of this error. and other suggestions are welcomed.

thank u in advans

To understand the error

mecej4 — Mon, 28 Jul 2014 12:55:44 GMT

To understand the error messages shown in #5, we need to see the contents of file cspblas_dcsr.c. Likewise, in order to investigate the linker error we need to know the linking command used.

Have you followed the suggestions given earlier in this thread?
