Compiler = Visual Studio 2005 Express (VS8) Angelsciprt Version = 2.15 I opened up the angelscript project for VS8, compiled it, copied the output library "angelscriptd.lib" to my project's directory, and added the library to my linker's dependency list. Now when I include "angelscript.h" I get the following link errors:

Angelscript documentation provides the following nugget of wisdom:

Quote: When compiling the static library you have to make sure that the correct compiler settings are used so that you don't get conflicts in linkage with the CRT functions. This happens if you for example compile the library with dynamically linked multi-threaded CRT and your application with statically linked single-threaded CRT.

Well, I see I'm getting CRT errors, but how do I figure out if my compiler settings are the same? I assume this is with respect to single-threaded/multi-threaded/multi-threaded DLL and Release/Debug. I think that they're both set to single-threaded debug, but I'm not sure how to check. And if something else is the problem, I really don't know what else to do.

Hi,

I'm currently experiencing the same problems with incorporating the AngelScript library into my MFC based project (SDI application, statically linked with MFC, using VC6).

Any advice would be very much appreciated, thanks! Meanwhile I'll try to find out on my own how to link the lib in order to fit with my application.

Hi polaris2013,

just managed to get the lib compiled and linked to match my MFC app (VC6) both for debug and release. Mainly had to do with the runtime library selection. Additionally the release build didn't compile at all, I had to copy the configuration from the debug build again and adjust it for release.

Let me know if you need the details.

Oh, well I solved it but since somebody else was wondering about the answer I'll go ahead and say what fixed it. There was a setting under

Project -> Properties -> Configuration Properties -> C/C++ -> Code Generation

that I had to change. Turns out multi-threaded debug was the way to go instead of single-threaded debug. Anyway, that was obviously not an obvious place to hide that setting so I hope this helps someone.

Thanks for giving the solution for this problem while I was away. I'll try to explain this better in the manual. And also fix the release build for the library.
