A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games.

VS 2010 is generating .lib and .exp files for a normal project, why?

6 posts in this topic

I never paid much attention to this, so I dont know if it started all of suddem or if it was doing that since the begining...but I dont know why those are being generated.

Searching google a bit looks like its because my project have stuff with __declspec(dllexport), but I didnt wrote any of those, nor I can find any of those using vs find entire solution..

Im afraid my project config files may be glitched or my compilation times can be greater than theyd need to be due the generation of those annoying files..

The only external stuff Im using on my project is boost, and Im using the boost serialization stuff, witch requires a lib linkage..perhaps is boost the guilt one? anything should I do or care about?

I would imagine Boost does some stuff, and it's also very likely the Microsoft CRT does some futzing too, especially if you use the run-time-linked libraries.


With that said this will have very, very negiligible impact on final compile time and you're making a mountain out of a molehill. Sometimes things need to be exported for stuff to Just Work and VIsual Studio is mature enough that basic kinks like this would have been worked out. :)

If you add
dumpbin /exports $(TargetPath)
as a post-build event for the dll/exe project generating the lib & exp, the build output will tell you what functions are being exported.

I know VS 2008 has a bug where certain build options will cause the project to export std::_Init_locks which in turn will generate an exp & lib for otherwise non-exporting projects. I don't know if they fixed it though.
