pthread support is part of the system library, no need for anything external. There actually is a /usr/lib/libpthread.dylib already present, and it's a symlink to libSystem.dylib.

Perhaps something else is wrong here.

Andre, what tool are you using to compile the program? If you're using gcc in the Terminal, it might help if you posted the command you're using, and the error message(s) you're getting. The full gcc manual is available on-line. Did you use the "-pthreads" flag in your gcc command?

I suppose libpthread is not the problem then. I'm not sure which gcc compiler i'm using. If i have to download that, then im not using one at all. I'm not very experienced in building in Unix. When i ./configure, that part runs fine, however during the 'make' part i get
Undefined symbols:
_GETLONG
_GETSHORT
_PUTSHORT
collect2: ld returned 1 exit status
make: * [ettercap] Error 1
ettercap is the program i am compiling. any ideas?

Andre,

Did you try tele_player's advice in your other thread ? After running configure, edit the Makefile as he suggests, then run 'make'...

Mac OS X 10.4 includes this library in the /usr/lib/ folder; the item in this location is a symlink which points to libSystem.B.dylib in the same folder.

Did you install Xcode?

the following will return the version of gcc that you are using.

gcc --version
