I work on C/C++ using Visual Studio 2008. I believe that I am not concerned about which runtime libraries are being used by my code as I have the developer setup. But when the executable is shipped, the runtime libraries being used need to be shipped alongwith. Am I right?
If yes, how can I identify which shared libraries are actually getting used? Or are there any libraries that we can ship without having to know this?
You’re correct, you need to ship a version of the C runtime libraries that matches the version you linked your application against. If you’re compiling with Visual Studio 2008, then you want to use the Microsoft Visual C++ 2008 Redistributable Package. As other folks mentioned, you can inspect your application’s manifest file to see exactly which version of the C runtime libraries it’s linked against.
Before shipping, it’s always best to install your product on a clean (i.e., non-developer) virtual machine and run Microsoft’s Dependency Walker utility to verify that your application uses the correct C runtime libraries.
