libmkl_scalapack_lp64.so: undefined reference to

libmkl_scalapack_lp64.so: undefined reference to `MKL_SCALAPACK_INT'

When link with Intel® Math Kernel Library 10.2 update 2 on SGI* Workstation with Intel® Xeon processor, the following error is reported:

libmkl_scalapack_lp64.so: undefined reference to `MKL_SCALAPACK_INT'
libmkl_scalapack_lp64.so: undefined reference to `Cdsendrecv'

The cause of this issue happens only when SGI's MPI library and libmkl_blacs_sgimpt_lp64.a library from MKL are used.

This is a known issue and this will be fixed in the future versions.


Workaround to fix this issue:

Compile a C source file with the below two lines and link it in addition to MKL:

#include
int MKL_SCALAPACK_INT = (int) MPI_INT;

一般链接so动态链接库，如果报错：undefined reference to `XXX'

说明动态库中XXX没有定义，可以使用nm/objdump命令查看该动态库的符号表，使用命令：
nm -t libxxx.so |grep XXX
查看，一般情况下XXX的描述都是U或者Undefine，只要写一个程序实现后打包至该动态库即可。
