PLEASE HELP! Josh

I just had a very similar problem. I have been using the library fine under Visual Studio, and I am trying to test my code on Linux now. Any help would be greatly appreciated.

If we exclude error in a library, when symbol is actually missing, there are not so many reasons that may cause undefined symbol error: 1. Library is missing from link command 2. Library is binary incompatible with test module code. The reason could be: different compiler version or different compilation options used for library and test module. 3. For some compilers. library should be listed before object files that refer to it. 4. Library is built improperly. Some object files are missing, for example. Using nm command usually allows to detect this. HTH. Gennadiy "Josh" wrote in message news:20060707165513.95719.qmail@web35302.mail.mud.yahoo.com...
