Which system is this on? I'd guess this is Solaris 9 or worse because that's the only system that I know which is broken enough not to have getopt_long.

Added Irix to the "broken" list in the wiki. getopt_long is a GNU extension, so... yeah. But I really like long options. :-(

I googled a getopt_long implementation and the file has 540 lines. That's a lot.

So plan B:
Grab a text editor and edit main.cpp. Remove the "g_LongOpts" array in lines 13 to 27. In line 117/119, change the calls to getopt_long(argc, argv, , g_LongOpts, &iOptIndex) into getopt(arc, argv, ).

If you got any problems with that, tell me which version of znc you are looking at and I'll patch main.cpp for you. (And yes, this will remove support for long options like --foreground and --debug from znc and make only the short forms like -f and -D work).

fantastic!!
will give it a try right away!
and i couldn't care less about long options anyway :-)

i'll try 0.096 first but wouldn't mind any other version either

okay, that worked like a charm but one more issue came up:

http://predef.sourceforge.net/preos.html says that irix can be identified via #ifdef sgi, so could you change line 489 in Csocket.cpp from
#if defined(sun) || defined(_WIN32) || (defined(__NetBSD_Version) && NetBSD_Version < 4000000000)
into
#if defined(sgi) || defined(sun) || defined(_WIN32) || (defined(__NetBSD_Version) && NetBSD_Version < 4000000000)

that worked just as well as the solution before!
had to replace install.sh with a real one and all was fine. now i'm the proud owner of a nice and current znc package for irix :-)

i have to say this was the best support i got in years. normally it's like that: "what? not linux? don't care." :-P

and for what it's worth the patch:

So you do know that irix is dead since almost 5 years? Good. :-)

For the getopt_long problem I did a proper patch which has the same effect as the one you got, but with the difference that we still use getopt_long() if it is available:
http://git.znc.in/?p=psychon/znc.git;a=commitdiff;h=2afe2a77629012b24d8d270437e94e98d1657ffc

I'll forward the change to Csocket.cpp the right person.
