I am moving it into the Trac system to raise its visibility. I believe it could be moved toward resolution by someone -- a newcomer, perhaps -- who was willing to spend some time doing Internet searching on the profiling options of various C compilers. Original description:[[BR]] '''The profiling options used in config/init/defaults.pm are specific to gcc. This should probably be specified in the relevant hints file.''' The relevant code in ''config/init/defaults.pm'' is this: {{{ if ( $conf->options->get('profile') ) { $conf->data->set( cc_debug => "" -pg "", ld_debug => "" -pg "", ); } }}} In the original ticket, Infinoid subsequently commented: ''This flag convinces gcc to generate profiling code specifically for the GNU profiler, `gprof`. I find it *extremely* unlikely that this flag would be available and/or mean the same thing for other compilers ...'' In addition, Andy Dougherty commented: ''[These options] are gcc-specific. A plain `-p` is common on Unix systems, but `-pg` is gcc-specific. For example, with Sun's C compiler, `-xpg` would be the equivalent flag. (Though Sun's C compiler also has other profile options selected by `-xprofile` ...)''
