[Llvm-bgq-discuss] mpic++11 Runtime Error on Cetus

[Hal Finkel]

Hi Michael,

How are you linking? The underlying bgclang wrapper script should add the necessary directories (/bgsys/drivers/ppcfloor/gnu-linux-4.7.2/powerpc64-bgq-linux/lib in this case) to your rpath so everything functions correctly.
