static GUI library statically linking SFML

[kennyrkun]

I'm writing a basic GUI system using SFML. It links SFML statically into it, and the lib itself is meant to be statically linked. Apparently this is bad, but I'm not sure how.

LNK4006 _vorbis_encode_init already defined in vorbisenc.lib(vorbisenc.obj); second definition ignored  SFUI    P:\aRepositories\SFUI\SFUI\vorbis.lib(vorbisenc.obj)

I am still able to link this library into main applications, and it works fine. But I don't like these warnings and I'd like to know if there's anything I can do to get rid of them, of there's a proper way to do what I'm wanting to do. The idea is that the main application ships with no extra dlls or installers.

What's your verbose build command? Sounds to me you're double linking stuff.

here's Visual Studio's verbose build output

Did you raise the warning levels? Never seen these warnings otherwise. I mean there are even some warnings for system libs. In the end those are just warnings that can be ignored.

Yes, I use W4 level for my release builds.

If SFML is statically linked to its dependencies, then your SFUI library shouldn't need to link in SFML's dependencies.

(I'm looking at line 114 of your pastebin - your SFUI lib is linking SFML static libs AND its dependencies)
