Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed|2005-07-19 05:27:40 |2016-8-31 --- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- Presumably it should be -pthread (the more portable option) not -pthreads (the redundant, Solaris-only option). It's currently only documented as valid for Solaris: https://gcc.gnu.org/onlinedocs/gcc/Solaris-2-Options.html and RS/6000 & PowerPC: https://gcc.gnu.org/onlinedocs/gcc/RS_002f6000-and-PowerPC-Options.html It should also be listed at: https://gcc.gnu.org/onlinedocs/gcc/GNU_002fLinux-Options.html
