Hi,

I'm trying to port a linux application to mac with Qt... And I've read in some forums that libnsl isn't supported on Mac, that it's included on libc. But I've tried to just erase the link -lnsl, and adding -lc, but it always stops at the same compilation line returning lots of undefined symbols but ending with the same single error: collect2: ld returned 1 exit status

any Ideas on how to fix this issue?

I even downloaded fink and apt-get commands to see if I could apt-get install libnsl but it doesn't find that package...


this is what Qt returns when I take -lnsl out:
