I'm working on porting amule to OS/2, starting with the command line client. I've gotton it up to linking, but I'm getting unresolved external errors. While I'm pretty good with C, I haven't done too much with C++. Perhaps I'm missing something obvious. Even if you can't tell me the solition, it would be good to know what theses symbols have in common that might cause an error.
Using OS/2 I'm compiling with gcc 3.3.5, but it is calling the OS/2 linker ilink. Most UNIX utilities have been ported to OS/2, although you might find a few of the command line arguments unfamilar, things work a lot like they do on UNIX.
I made some small changes to the makefiles. I took out the "-lpthread" and "-ggdb" parameter.l
First there error:
