I have been racking my brain trying to figure out how to resolve a duplicate function error (LNK2005) and have been unsuccessful. I have followed direction on the following link as well: http://msdn.microsoft.com/en-us/library/72zdcz6f(v=VS.80).aspx Attached is a printscreen of where the error occurs. The following are issues I have come across:
1. One thing I noted in the output build report is that after invoking the linker with LINK.exe, one of the linker parameters that prints is /incremental:no, though when I look under Solution Explorer\Properties\Configuration Properties\Linker\General\Enable Incremental Linking the setting is Yes(/Incremental). Is there a setting somewhere that is causing an over-ride of the setting? I have done a build/clean for the project.
2. I have specified under Solution Explorer\Properties\Configuration Properties\Linker\Input\Ignore Specific Library the mfcs90ud.lib file. I added it back as an additional dependency. Though I still have problems with this lib file.
