Building projects with older libraries

Question

I am trying to build an old project, last build with visual studio 2003. I've upgraded the project and source code to visual studio 2019. Everything compiles. I am getting a lot of undefined globals from the stl. The project that I am building uses a lot of libraries which were probably built with visual studio 2003 and there appear to be some stl incompatibilites.

Is there any way that this can work, or do I need to rebuild those libraries with visual studio 2019? I haven't been able to locate the source code for those libraries so rebuilding them isn't really an option.

Answer 1

yes, I am building x86 debug and all libraries have been added.

As I said in the original post, my project is including libraries that have not been built since visual studio 2003. There appears to be a mismatch between the stl used in those libraries and the stl used by vs2019. I think I need to rebuild those libraries, but the source code is gone, so that's not an option.

I'm just trying to find out if there is any way that I can get this working without rebuilding those libraries.
