PluggableGeometryExample not building, Segmentation Fault and General Question #407

Closed GTO2013 closed 3 years ago

GTO2013 commented 4 years ago

Hi, I am currently researching how to build an ospray module. I have tried to compile the bilinear_patch module but it doesn't compile when you set the OSPRAY_MODULE_BILINEAR_PATCHflag. This is because in script/superbuild/build_ospray.cmake you are using the BUILD_OSPRAY_CI_TESTScmake variable in line 144. Is this intended?

I have also tried to run ospExamples, which ran fine on v2.0. The recent version depends on OIDN now. I have set the flags to compile that module, but when I run the ospExamples I just get a segmentation fault.

I also have a basic question: How do you do a partial build (only on changed files) without a full rebuild?

Thank you!

A very late reply, so sorry about that.

The crash of ospExamples when OIDN could not be found is fixed.

Then, superbuild. It is mainly for "build once". If you like to play around with OSPRay's CMake options, you need to do that in the ospray/build subfolder (which superbuild created), not in the top-level build directory. Building there is also incremental, i.e. only changed files are re-built.
