IPX tools build error - Slack 7

["Bill Layer" <b.layer@vikingelectronics.com>]

I'm trying to get the greg@caldera.com IPX tools built under Slack7 / 2.2.13, and am encountering the following fatal errors when I 'make' or 'make all' (pardon my paste):

billbob_linux:~/ipx-1.0$ ls

Can someone shed light on the issue? I'm not a C programmer, but I am guessing that either the ipx.h header file or the program itself is broken.

If one of you can compile it successfully, I would be in your debt if you could send me the binaries. BTW, the greg@caldera.com mail addr is also broken :/

thanks,
Bill
