Can you try compiling without the -qkeyword=__volatile__? It looks like XLC now has some support for GCC-style inline assembly, but it doesn't seem to be working in this case. If that doesn't work, try setting CFLAGS and CXXFLAGS to include -qnokeyword=asm, which should disable GCC inline assembly entirely. I don't have access to a linux cluster with the XL compilers, so I can't verify this. But it should work. Brian
No good sadly. The same error continues to appear. I had actually initially attempted to compile without -qkeyword=__volatile__, but had hoped to force xlc to recognize it. This is obviously more of an XL issue, especially as I've since found that everything works flawlessly in 32-bit mode. If anyone has more suggestions, I'd love the help as I'm lost at this point. Thanks for the help thus far, Justin.
