Build All failed.`

When I hit the build all option in CMake this is what I get. I was able to run all the binaries solutions including the ones with Optix. So far I have cuda 11.1, optix, cmake(visual studios 2019), and I am trying to run this on a rtx 2060.

looking a bit deeper into the problem it looks like Cmake is having a hard time with target_link_libraries(gvdb PUBLIC cuda.lib) in gvdb_library->CmakeList.txt. I have tried redownloading Cuda 11.1 and Cuda 10.2 but to no avail.

[NBickford-NV]

Hmm - CUDA 11.1 + OptiX + Visual Studio 2019 is one of the platforms we test on, so this is definitely an issue! It sounds like somehow CMake is finding the CUDA include directory at C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.1\include, but not including the directory at C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.1\lib\x64 to the linker. By any chance, did you get any interesting messages during CMake configuration (or if you delete the cache and re-configure the CMake project) - especially at the top, where CMake says where it found CUDA paths?

Thanks!

I know for sure I have re-configured the project many times. I have not been able to find anything strange in the Cmake build. However, this is what I get as the full build of the project:

I just tried deleting all the cash and re-building it. I got this 'The CUDA compiler identification is NVIDIA 11.1.105' along with ncvv linking properly. Which seems very normal. I also got this notice 'host_defines.h is an internal header file and must not be used directly. This file will be removed in a future CUDA release. Please use cuda_runtime_api.h or cuda_runtime.h instead.'.

[NBickford-NV]

Ah, so is the linker error fixed now?

Looks like the host_defines.h warning was coming from a radix sort file which we no longer use (we use Thrust instead) - so it should be fixed now if one pulls the latest code!

[capslpop]

Hmm, I just downloaded the latest code and tried compiling it but I still got the same linking error: cannot open file 'cuda.lib'

[NBickford-NV]

OK, I managed to reproduce the issue! The key is that you're building using Ninja, instead of from within Visual Studio. Ninja can't find the directory containing cuda.lib for some reason, which is why it failed. (I reproduced this by using the x64 Native Tools Command Prompt for VS 2019 along with cmake -GNinja.)

I think I've just fixed this by adding some code in gvdb_library's CMakeLists.txt to get the absolute path to cuda.lib, which seems to make it work for Ninja!

I don't know enough about Ninja to know why adding the x64 lib path to the user's PATH doesn't seem to help Ninja here, or why this works in Visual Studio but not in Ninja, but let me know if this fixed it!

[capslpop]

Yes, it works! Thank you so much! I have been scratching my head on this issue for a while now. It is very satisfying to see the build succeeded! Thanks again!
