Hi, I am getting a compilation error while trying to compile MPICH on my Mac desktop. I installed the latest GNU compilers using Homebrew.

gcc -v Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/local/Cellar/gcc/5.2.0/libexec/gcc/x86_64-apple-darwin14.5.0/5.2.0/lto-wrapper Target: x86_64-apple-darwin14.5.0 Configured with: ../configure --build=x86_64-apple-darwin14.5.0 --prefix=/usr/local/Cellar/gcc/5.2.0 --libdir=/usr/local/Cellar/gcc/5.2.0/lib/gcc/5 --enable-languages=c,c++,objc,obj-c++,fortran --program-suffix=-5 --with-gmp=/usr/local/opt/gmp --with-mpfr=/usr/local/opt/mpfr --with-mpc=/usr/local/opt/libmpc --with-isl=/usr/local/opt/isl --with-system-zlib --enable-libstdcxx-time=yes --enable-stage1-checking --enable-checking=release --enable-lto --with-build-config=bootstrap-debug --disable-werror --with-pkgversion='Homebrew gcc 5.2.0' --with-bugurl=https://github.com/Homebrew/homebrew/issues --enable-plugin --disable-nls --enable-multilib Thread model: posix gcc version 5.2.0 (Homebrew gcc 5.2.0)

I am getting the following error while compiling MPICH: CC src/mpltrmem.lo /var/folders/qf/q3tp7kgn0gz6qj5_c2nr4qqm001qq3/T//ccyirdXM.s:491:suffix or operands invalid for `movq' /var/folders/qf/q3tp7kgn0gz6qj5_c2nr4qqm001qq3/T//ccyirdXM.s:495:suffix or operands invalid for `movq' make[2]: *** [src/mpltrmem.lo] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 I have attached the configure log c.txt and the make log m.txt.
