More issues with Linking in VS2010

[ireg]

I am new to bullet and I'm trying to get a Hello World project of sorts started. I am working with Visual Studio 2010 (possibly 64 bit but not sure) in Windows 7 x64bit. I followed the steps given in the wiki, but when compiling I get a bunch of unresolved external symbol errors, attached below. I did a search on the forum and it looks like several other people have had similar issues. I've tried various solutions but nothing has worked so far.

I've already checked that the Link Library Dependencies option in the project properties page is set to Yes. I've also manually added BulletCollision.lib, BulletDynamics.lib, and LinearMath.lib into the project, and added that folder to the "%bullet_dir%\msvc\2010\lib\Release" folder to the additional libraries directory option. Nothing helped.

I can't figure out what I'm doing wrong. My hunch is that it might be an issue of mismatch between using 32bit vs 64bit features somewhere, but I don't know where to look.

Take a look here http://bulletphysics.org/Bullet/phpBB3/ ... f=9&t=5621 I had the same issues. I am using 64bit windows 7 and I am using VS2010 you will find so long as your trying to compile an x86 program no issues come up from that.

Have you added the additional dependencies in the linkers additional dependencies? Perhaps give a show of your layout, do take a look at how my config looked there are pictures on there and basically the same 20 odd linker errors :p
