Linker options ============== Use "-Wl,OPTION" to pass "OPTION" to the linker. ... which means a proper header is missing for Assembler options. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Component|target |driver Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2010-09-20 09:30:32 date| | Summary|gcc 4.5.1 -march=corei7 |Header missing for assembler |fails |option help. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45731 ^ permalink raw reply [flat|nested] 4+ messages in thread
