CUDA 4.0 RC / thrust and dynamic runtime libraries under MSVC /MD

[GoogleCodeExporter]

Hi,

a code compiling with cuda3.2 is no longer with cuda 4.0 if the windows runtime 
libraries as choosen as dynamic.

In the cuda 4.0 SDK, the marching cube example is using thrust and is 
compiling/working.

By default, this project is using static runtime libraries /MT
A soon as I compiles with dynamic runtime libraries /MD, I obtain a bunch of 
warnings relatives to std::basic_string and linking errors...
(since my software uses compiled libraries that link dynamically I have no 
choice on this option)

This happens, as soon as the project and .cu files are compiled with /MD and 
only one thrust header file is included (a function call is not even required)

(sorry for the french output...)

PLEASE HELP ME!!!

This is not a Thrust issue.

You need to ensure that all your project's source files are compiled with 
consistent code generation options such that the same MS runtime library is 
linked in.

All the sources ARE compiled with consistent code generation.

Please try the "marching cube" example in the cuda 4.0, there is only 2 source 
files.
By default they are compiled with /MT -> no problem
and now try to compile them with /MD -> link errors

There is no problem when no Thrust files are included. And the same code is 
working correctly with cuda 3.2 + Thrust 1.3.

So please reconsider the question ;)

Actually I simply tried to compile it with cuda 3.2 and the Thrust library 
distributed in the cuda 4.0 RC toolkit and it is working.
So you should have right, it is not a Thrust issue.
Do you think the problem can come from cuda 4.0 nvcc?

It's possible this is an nvcc issue.
