Have you fixed the problem?
On BG/Q, Version 4.6.5.
Here, the /libmass_simd.a is under /opt/ibmcmp/xlmass/bg/7.3/bglib64
(it may different from yours).
During cmake I added
-DCMAKE_C_FLAGS="-O3 -L/opt/ibmcmp/xlmass/bg/7.3/bglib64 -lmass_simd"
It works on my side, you may do a check by yourself. Please also pay
attention to the compiler you use. XL is different.
