the Demo can not compile,why?

[sssa2000]

the demo:
Extras/test_BulletOde.cpp

i create a project, and include the ode's lib and bullet's lib
but complier report:

why?

[Dirk Gregorius]

You must link the CRT library dynamically

[sssa2000]

sorry, can you tell me how can i do it?
thanks!

[Dirk Gregorius]

You need to make sure that the libraries you want to use both link to C Runtime (CRT) DLL instead to the static LIB. I don't know if these are available precompiled. You can easily build these libraries yourself:

1) Open the Solution
2) Right - click onto each project -> choose "Properties"
3) In the new window open Configuration Properties -> C/C++ -> Code Generation
4) Then in the right hand side window (in the middle) swith the entry "Runtime Library" to "Multithreaded DLL"

i have try it,but it not slove the problem.

[Dirk Gregorius]

Did you build both libraries with these settings and your own application?
