QtPlugin using CUDA Libraries

[mane02]

Hi Guys!

Actually I'm developing a desktop application showing OpenEXR images. OpenEXR is an open HDR format so tone mapping is neccessary to show a rgb picture on screen. Users of the application should be capable to implement their own tone mappers. So I implemented a plugin interface and also use it myself to implement different tone mappers an filter functions. The application is compiled in 64bit.
One function is using the CUDA-API by Nvidia and is already running fine within another software. The plugin implementation using CUDA is compiling an linking. But QPluginLoader::instance() returns 0 when try loading the plugin with CUDA. When removing CUDA the plugin is loaded. So I guess the plugin interface is implemented correct in the plugin. Has anyone experiences with CUDA (or may be other external libraries) used in QtPlugins???

I'm thankful for every help!!!

Hi and welcome to devnet,

Did you check the value of errorString() ?

Hi,

thanks for your try to help me, but I solved it already. I had forgotten to copy the CUDA.dlls into my directory so the plugins couldn't be loaded due to their dependencies to CUDA.

Bye!
