I have a project consisting of one main project, 3 projects that use boost and several other projects that reference static libraries. These 3 projects use momentum. But I can’t build my main project. I have a lot of error LNK2005: .... already defined in ...
mistakes. As I understand it, activate the automatic linking of libraries with both of these projects. I tried using BOOST_ALL_NO_LIB , but that did not work. After adding this macro, I still have unresolved characters, but the override errors are still here. How can I solve this problem?
UPD1: there are about 400 + errors. Here is the first one:
