How to use Intel's Math function library with gcc?

Question

I am trying the following: gcc -o foo foo.c -L /path/to/directory/containing/libimf.so -limf and I have used 'log2' function in foo.c. I want it to link with Intel optimized library function but I am getting the following error

/usr/bin/ld: skipping /path/to/libimf.so when searching for -limf

/usr/bin/ld: cannot find -limf

collect2: error: ld returned 1 exit status

I was using the wrong libimf.so for the linking. There were two different libimf.so at two different locations corresponds to Intel MIC and Intel IA64 architecture. It worked with correct one(IA-64).

Argument -L expects a directory, not a file.

It is directory path containing libimf.so. I edited the description. – user1669844 Aug 24 '17 at 17:09
