dgGetIdentityMatrix() - Unresolved external symbol

Postby Hattress » Fri Nov 21, 2014 6:43 am

Hi everyone,
I am experiencing this "unresolved external" error when trying to compile my project. The same issue is found using the "Getting started" sample tutorial.

I suspect it might be code not updated for the latest version - or am I simply doing something wrong? Other Newton functions runs fine.

Code: Select all
Error   1   error LNK2019: unresolved external symbol "class dgMatrix const & __cdecl dgGetIdentityMatrix(void)" (?dgGetIdentityMatrix@@YAABVdgMatrix@@XZ) referenced in function _main   C:\Users\User\Documents\Visual Studio 2013\Projects\source\source\source.obj   source

I'm not sure if I understood your question... I am using project_vs2013_dll and Newton.DLL in Visual Studio project folder.

but of you are compiling the DLL and the DLL links, then there are not external references.
are you trying to call that function yourself?

Yes, that is correct.
The odd thing is that it ONLY happens to the matrix function!
Do you have any guide on how to make the libraries static?

Update: I believe I have found the problem, you also have to link the core_d.lib. Have not seen this referenced anywhere, but it's fixed now.
