one question about "Directshow + CUDA

[vuarnet0318]

Hello...all , I'm Eric...
I checked CUDA Zone Forum and found this article...
http://forums.nvidia.com/index.php?showtopic=86779&hl=

I want to create one directshow transform filter combined with MyCudaProj.dll (<-- I created it)
Now I use "LoadLibrary" function to load *.dll ...
But it always can't be loaded...
I'm sure *.dll is ok, cuz I test it with VS2005 console project successfully... confused.gif

Another way I think is to add *.cu in Directshow Filter proj ...
In order to let Directshow transform function call function of *.cu successfully,
I add (Extern "C") to define the function of *.cu...
But... the Vs2005 compiler always shows this message

nullnull.obj : error LNK2019: unresolved external symbol _TestHelloCUDA@0 referenced in function "private: virtual long __thiscall CNullNull::Transform(struct IMediaSample *)" (?Transform@CNullNull@@EAEJPAUIMediaSample@@@Z)
1>Debug\nullnull.ax : fatal error LNK1120: 1 unresolved externals

Did you have any experience about this...
I also check my project setting many times, but nothing happened... pinch.gif>_<

makefile有问题.link时没加上包含TestHelloCUDA的obj文件.(好像是xxx.cu.obj?)

I just copy the *.obj file about *.dll ...
But it still has nothing...

Can you share more detail about your experience ...thanks~~! ^^

otherwis... I create ststic library to be used in Directshow Filter function...
But get the information as below ...
Error Message : LNK 2019 unresolved external symbol ....

I add extern "C" to define my cuda function...

nothing happened... how sad... >_<"
