The code is on http://code.google.com/p/zxstuff/source/checkout and here is the Code::Blocks Project zxStuff.zip <http://gcc.1065356.n5.nabble.com/file/n983603/zxStuff.zip> , my problem is that the compiler thinks zxVECTOR_resize & zxVECTOR_opAdd are undefined and just stop there (the stopping is desired btw). I cannot for the life of me figure out why this is. -- View this message in context: http://gcc.1065356.n5.nabble.com/Confusing-undefined-function-which-I-know-is-defined-tp983603.html Sent from the gcc - Help mailing list archive at Nabble.com.
