Error compiling on Windows 10, Optix 7.3

[drperpen]

Hi,
I get errors of this type, all of them related to optix_program.vcxproj:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\include\xutility(1309): error : expected a "(" [E:\dev\instant-ngp\build\optix_program.vcxproj]

Not sure if this is Visual Studio 2019 related or Optix related.
Thanks!

To be able to help, further information about your compiler versions, cmake version, operating system, GPU(s), as well as full logs are required.

Hi @Tom94 and thank you for your reply and your amazing project, which I believe sets a milestone, if not a turning point, in the field of 3d representation from 2d images. Gratulieren und vielen Danke!

I made it work with no issues on Ubuntu 18.04, but still struggling on Windows 10. My GPU is Nvidia Quadro GTX 5000 (16 Gb) and here is the output of the files build:

@drperpen try clearing the cmake cache or removing/renaming the build folder and run the cmake commands to configure and build in a developer command line, if you aren't already using that. also pass in visual studio as the generated target solution by passing this to cmake while configuring:

cmake -G "Visual Studio 16 2019" ...

CUDA extensions for building with Visual Studio are installed part of the CUDA installation if it finds the Visual Studio toolchain and other toolchains like Ninja may default to some MSVC version that didn't get that CUDA installer treatment.

I have a feeling, it may be due cmake generating for another toolchain but more likely, the build environment not being set in command line. Default cmd doesn't set the env vars for building... You will have to search on windows for something like this instead of cmd x64 Native Tools Command Prompt for VS 2019 It is only installed with Visual Studio along with command line toolchain... sometimes you will need to specify this to be installed in the installer or sometimes you will need to create a blank project in visual studio community edition to skip past visual studio pro free trial trap.

Actually, it is not related to Optix.

I experience similar error with MS VS 19, CUDA 11.3 and Optix 7.4

After I upgrade CUDA to 11.6, the errors are gone

[drperpen]

Thanks, using CUDA 11.6 and Cmake GUI made it.
