error LNK2005: * already defined in *.lib(*.obj)

Problem:

When I build Seahorse in branch bsquare, sometimes I got lots of linking error like this

error LNK2005: * already defined in *.obj

I’m sure it had been successful built before, but it doesn’t work now.

Solution:

I found it can be avoid if putting /FORCE:MULTIPLE into build options.

Right click on project -> Properties -> Linker -> Command Line -> Additional Options -> add /FORCE:MULTIPLE

(It just a first-add, please see the first reference for root cause.)
