[Solved] Linking with binary libraries compiled with other MSVC version

[goetz]

From an ABI (Application Binary Interface) view this should not make any difference. It's more a question of SP1 or not. I once got bitten by this when I used the precompiled libs that the Trolls provide; these were built with VS2005+SP1, I had no SP1 installed (and could not upgrade for some reason). I could not link my application against these DLLs and went off to compile Qt by hand, so that they depend on the very same libs and version my installation provided.

I know, all this is a big nightmare :-(

If you can grab the sources of the lib you use, it would be best to compile it yourself.

Unfortunately, it's impossible. Thank you for explanation.

No problem, you're welcome. We've now ended with three virtual machines, one for VS2005 without SP1, one for VS2005+SP1 and one for VS2008 each. That's only to separate from the different dependencies.

yes, Volker is right about SP1 and it can be a root of problem I think.

I am recompiling now and will report about result to compete the topic.

Yes, the SP1 was a root of the problem.

Thanks all for assistance.

Linking is safe (fails at build time), the painful part comes when you use the library and when deploying. Definitely not a recommended thing to do.

When I install service pack then the used library is the same. Thank you for recommendation.

You must install both runtimes (MSVCRT, MSVCP) on the target machine. There are installers from Microsoft for that (vcredist exe or an MSI include); you must execute both .exe or include both MSI snippets.

Thanks. It seems that I can eliminate library without SP1.
