aircrack-ng @1.2-rc1: Undefined symbols _strnlen _dprintf

[jbwmyoung@…]

I've been having some trouble installing aircrack.

The build fails, and I get the error: command execution failed The log file is attached.

I am running OSX 10.6.8. I have tried cleaning and updating the port tree.

Initially, I was trying to do it from source (instructions: ​http://www.aircrack-ng.org/doku.php?id=install_aircrack), but was running into all sorts of errors (e.g. endian.h missing, lots of @GOTOFFS in the sha1). I tried to debug with no success. I do have command line tools installed, and if I do a search I see multiple endian.h files on my computer.

i.e. strnlen and dprintf are missing, presumably because 10.6.x's libc did not have them. strnlen is easy to fix, because it is easily implemented. Not sure the same thing holds for dprintf, though. If you want a quick fix, updating to a more recent version of OS X (for example one that still receives security updates) is advisable, but let's see what Ryan has to say on this.

Thanks for the info. If at all possible, I'd like to avoid updating to a newer OS. However, I understand that it is possible that applications/ports will only support current OSs.

The upstream ticket has moved to ​https://github.com/aircrack-ng/aircrack-ng/issues/1682. The developers have closed it without fixing it, on the basis that Snow Leopard is old. They appear to be willing to accept a patch to fix the problem, if you or someone would like to provide them with one. There is an additional problem on Snow Leopard, filed as ​https://github.com/aircrack-ng/aircrack-ng/issues/1717, which has been similarly closed without a fix.

Fixed in [6629d980fa6cdd2d451e38751ba8bd89cde29117/macports-ports] by using the legacysupport portgroup.

There is an additional problem on Snow Leopard, filed as ​https://github.com/aircrack-ng/aircrack-ng/issues/1717, which has been similarly closed without a fix.

Fixed in [500cc2acef92ba899ac0e8486d69f1aac09d19a4/macports-ports] by blacklisting clang < 503.
