yes, the GL interoperability of cuda requires this call to be within the context handling part of OpenSG (Window/Window tasks). > But if that is the case, why I can successful build and install the whole > library? Thanks. that most likely is a bug in the CMake setup for the tutorials (I'll have a look). The system lib builds because cmake detects cuda and links the correct libraries, the tutorial cmake setup seems to miss this part. Shared libraries are also less sensitive against missing symbols, you have to force missing symbol detection during linking, by default it is not checked. Normally I would expect the linker to pick up this transitive dependency as long as it could find dependent libs within the LD_LIBRARY_PATH, could you post the complete output. Which rocks version are you using so I can try it in the same environment. kind regards gerrit ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
