You typed a '1' instead of an 'l'. And you forgot the comma. No, wait a minute, I was wrong. The actual problem is that you aren't correctly describing what you've done. Cut and paste stuff from your shell into your email, don't just make it up or you'll inevitably get it wrong. Fortunately I can still tell what the actual error is: > the error i get now is: > > /usr/lib/gcc/i686-pc-mingw32/3.4.4../../../../i686-pc-mingw32/bin/ld: > unrecognized emulation mode: no-cygwin > Supported Emulations: i386pe > collect2: ld returned exit status > > at the prompt i did a ls /lib/gcc/i686-pc-mingw32 and it returned > 3.4.4 so that seems right. > > any clues or suggestions?? thanks all in advance! It's not a linker option in that sense; you just need to make sure you've passed it to gcc or g++ along with all the .o files and it knows how to drive the linker from that. So just remove your -Wl altogether; the plain old "-mno-cygwin" that you have immediately after the "g++" will do the job. The effect it has is to cause g++.exe to pass different -L options to ld. cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
