C++ Question Getting static library to link with any compiler

[Zatnikitelman]

I'm working on a utility static library (.lib) for stuff I'm doing in Orbiter, and I can get it to compile fine with other VC++2008 projects with lots of help from dbeachy1, but I can't get it to compile with a VC++2010 project. I was able to get rid of a C1047 Error, but now I'm being hit with an LNK2001 error:

error LNK2001: unresolved external symbol "public: static void __cdecl std::_String_base::_Xran(void)" (?_Xran@_String_base@std@@SAXXZ)

Everything I've found via Google tells me that the problem is the .lib was built in VS2008 while I'm trying to build in 2010. I know it's possible, otherwise how would I be able to compile against Orbiter's own static libraries?
Thanks for any help,
Matt

I know it's possible, otherwise how would I be able to compile against Orbiter's own static libraries?

That's probably because std::_String_base::_Xran(void) function isn't used by Orbiter's static libraries.

Ok, is there a way to find out where it's used or, how do I not use it? Googling for it just gives me results of people with errors like mine.

My best guess is that it's used by a 'string' class you use in your code of the static library. If there are no many different operations on strings, you could try replace them with C char[]s.

You could use various tricks depending on your project. Would need to see code to be more specific. In the end you can usually resort to doing a dynamic linkage. I have had success in compiling orbiter add-ons with MinGW.

From one of the forums about this ( http://social.msdn.microsoft.com/forums/en-US/vcgeneral/thread/5ac28a31-3339-4db1-90f4-68edad360309 )

I figured out that newly built cryptolib.lib went to different folder and the main app was trying to link to old .lib file. As soon as paths were fixed the issue resolved.

It also suggested:

I got rid of this problem by just doing a "Rebuild All" of my project.

Have you tried these?

@orb: I got rid of all references to std::string in my library code, but I still have the same error when using the library. It only occurs when I include the class in my library, if I comment out the class, but still #include the file, it compiles fine.

@Hielor: until I get things worked out, I've been doing doing rebuild instead of just build and of course it's still throwing the error.
