WorldServer trying to read 0x0000

Okay, the world server works... except not really.

It crashes within 10 seconds after entering the world. Before it crashes, I can walk, talk to the fairy NPC, and even kill jellies. In the distance, I can see text bubbles saying:

The gang of hooligans hav
recently been increasing in

That's exactly how the bubbles look. ("hav" is not a typo I made) They reappear and disappear around the screen, and in random spots. (The arrow of the txt bubble points at the ground... and there's nothing there. It looks as if the ground is talking. )

Here's the debugger output

Program received signal SIGABRT, Aborted.
In select$DARWIN_EXTSN () ()

Callstack:

#0 0x924966f2 select$DARWIN_EXTSN() (??:??)
#1 0x1de1 CWorldServer::ServerLoop(this=0x700000) (World Server/worldserver.cpp:328)
#2 0xfd4c CServerSocket::StartServer(this=0x700000) (Common/SocketServer.cpp:186)
#3 0x479cd main(argc=1, argv=0xbffffa50) (World Server/main.cpp:71)

If I leave the Rose window open after the server crashes, the bubbles multiply in number. The screen is literally filled with a bunch of text bubbles.

(Note I'm using v131)

Paste a couple lines around 328 in WorldServer.cpp (So paste 310 - 350 or so)

i posted a thread long time ago what needs to be done to port osrose rev80 to linux and if i remember right i even gave some experimental port there. why dont you use that as a start for porting to osx/bsd? all rose emulators share huge chunks of code so it will be definately worth to take a look.

Looks like there's a lot of mixup between pthread and FDS, because of the lines
" if(!Config.usethreads)
FillFDS( &fds );"
&fds is never filled, and therefore when you call select, it tries to access random memory, and OSX apparently has stricter memory management than Windows does.

Are you speaking of the zrose server? I checked that out and it looked like it had a lot of functions missing. To use it as a base would be beyond my programming skills unfortunately.

I think the server just isn't coded for OS's with strict memory management. I'd have to recode a lot of stuff I bet, and that's beyond my skill as a programmer as of now. Thank you all for your help. I'm just going to run it on my Windows PC. It would have been nice to have it on my macbook, 'cause the fan is a lot quieter. Oh well.

Why don't you do a Windows Partition (BootCamp) or even use VMware for Mac to have a Windows virtual server (it's called VMWare Fusion I think for Mac).

no i spoke of my own port. it was rev80 that time so it should be suited.
