libiomp problem

roddur — Sun, 21 Dec 2008 05:40:21 GMT

i have installed ifort11.074 in fedora10.while i compile my threaded job , it shows error

error while loading shared libraries: libiomp5.so: cannot open shared object file: No such file or directory

while this library is present in the same file as .a version. a obvious workaround is compile the job statically. but my worry is why it cannot access the libiomp.so while it can access libiomp.a residing in the same dir.?

I don't know if it will solve your problem.

But make sure the library directory is in the ld path.

In Slackware, I put the path in /etc/ld.so.conf

pc:~$ cat /etc/ld.so.conf
/usr/local/ga-4-0-8/lib/LINUX64
/usr/local/intel/cce/10.1.012/lib
/usr/local/intel/fce/10.1.012/lib
/usr/local/intel/mkl/10.0.1.014/lib/em64t
/usr/local/lib
/usr/i486-slackware-linux/lib

After this you must run, as root, ldconfig command.

I am not sure, but there are another ways, such as put the library path in LD_LIBRARY_PATH, and export it.

As Rafael indicates, the expectation is that you set LD_LIBRARY_PATH, as sourcing one of the ifortvars scripts would do.
