Short version ============= MTT turned up a problem with -std=gnu99 on OS X Leopard, which ships with the gcc 4.0 compiler (OS X Snow Leopard ships with gcc 4.2, and doesn't have a problem). Does anyone have gcc 4.0 on Linux? I'm wondering if the same problem would occur.
More details: ============= >From our friends at Absoft: ----- The -std=gnu99 is causing the problem when used with gcc-4.0 ( the default on Leopard with Apple's XCode 3.1 development tools ): BigMac:ompi cag$ gcc --version -std=gnu99 -c conftest.s conftest.s:2:3: error: invalid preprocessing directive #_gsym_test_func conftest.s:5:3: error: invalid preprocessing directive #_gsym_test_func BigMac:ompi cag$ gcc-4.0 -std=gnu99 -c conftest.s conftest.s:2:3: error: invalid preprocessing directive #_gsym_test_func conftest.s:5:3: error: invalid preprocessing directive #_gsym_test_func BigMac:ompi cag$ gcc-4.2 -std=gnu99 -c conftest.s BigMac:ompi cag$ On Snow Leopard with Apple's XCode 3.2 development tools, the default compiler is 4.2. ----- The compile line he's talking about in particular is from a configure test in opal/config/opal_config_asm.m4, where we're looking for assembly global symbols. The source that we're trying to compile is: ----- .text # _gsym_test_func .globl _gsym_test_func _gsym_test_func: # _gsym_test_func ----- (configure tries a few prefixes) But the "#" token with the -std=gnu99 option is causing failures where it shouldn't (i.e., it causes configure to abort because all the assembly tests looking for the global symbols error out due to the # token. So I think we either need to find a workaround for this assembly test or whack the idea of the C99 stuff. :-( On Jan 24, 2011, at 10:29 AM, Nathan Hjelm wrote: > No, they didn't get added (adding them now).
