So I have a Visual Studio 2010 project that uses external libraries and in order to get it compile without LNK2005 I had to juggle arround with the order of the libraries in the linker settings.

I got it to compile fine in release mode, but for whatever reasons I don’t manage to get it to compile without LNK errors in debug.

Is there no way to generally ignore LNK2005 and tell the linker to simply use whatever he encounters first?

Thanks!

//edit: here are some of the errors output of the PARTICULAR problem. however I already tried to solve that in different ways with each solution giving me different linker problems. hence i’m looking for general solution to ignore LNK2005

    You may try the linker-option /FORCE (Force File Output in the Linker General tab of the Project Properties). This will force the linker to create a exe/dll even when such errors occur. But its left to you to find out if this exe does work at all or even correctly. After all i would not recommend this strategy.

    Linker errors can sometimes be tedious to solve, but usually it has to be done only after migrating or setting up a project. This may take quite a while – it sometimes took me more then a day, but it should be done properly.
