Salutations! I get an error while compiling mpich-3.0.4 on 32-bit Arch Linux with GCC 4.8.2-3 (from Arch official repositories). I am getting the following error: /home/test/build/src/mpich-3.0.5/src/pm/hydra/tools/topo/hwloc/hwloc/include/private/cpuid.h:39: Error: symbol 'Lhwloc1' is already defined Makefile:708: recipe for target 'topology-x86.lo' failed Any help would be greatly appreciated!
