Helloooooooooo again, I'm getting several linking errors. This is not the only problems, but it is one I've never seen before. It says something along the lines of undefined reference to `SUBSYS::SUBSYS[not-in-charge]()' I've googled it and pretty much people are saying that this is due to libraries having been compiled with a different version of g++ than is currently being used. Is that correct? I've been looking through the option of GCC, and have noticed a few option dealing with application binary interfaces: -fabi-version=n Wabi ***************************************** Doing a full recompile would take a really long time, so I thought I'd first check if they might make a difference. Would setting -fabi-version=0 help ? Thanks again, Yamin ---------------------------------------- This mail sent through www.mywaterloo.ca
