in a project for a LD_PRELOAD module, i like to use -no-undefined because undefined symbols will not work in it at all. i would like to see a link error up front rather than random runtime failures. googling around shows patches from 6-8 years ago. they refer to an older glibc bug (which at this point makes it a bug on decade old systems) that should be accounted for, but otherwise there wasnt any response to the proposed patch. is there any real reason for Linux not supporting something so basic as -no-undefined ? especially considering it only needs one linker flag (-Wl,--no-undefined) ? -mike
