NeRF

Repo: https://github.com/NVlabs/instant-ngp

Steps (see their readme also)

install CUDA toolkit https://developer.nvidia.com/cuda-downloads?target_os=Windows&target_arch=x86_64&target_version=10&target_type=exe_local
- you can remove all the extras, like geforce experience and docs etc *i installed 11.4
install cmake https://cmake.org/download/ (latest release, not RC), i took 3.22.5 *3.23 doesnt work?
install optional (for DLSS) https://vulkan.lunarg.com/sdk/home#windows (base sdk only)
make folder somewhere, lets say E:\apps\NeRF\
open command prompt into that folder *note should use "Developer Command prompt for VS 2019" (search from start menu, if not found, you have vs in different drive?) "D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\VsDevCmd.bat" ?
cd into that folder E:\apps\NeRF
git clone --recursive https://github.com/nvlabs/instant-ngp
cd instant-ngp
cmake . -B build
cmake --build build --config RelWithDebInfo -j 16

IMPORTANT NOTES

Install all tools into default locations and everything is 100x easier! (vs, cuda, cmake..) *most of these errors happened before i did that
2022 is not supportet yet, NVlabs/instant-ngp#132 (comment)
VS2019 requires desktop development with c++
VCTargetsPath REQUIRES backslash in the end: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\

ERRORS

NOTE: wrong msbuild version is runned, 2022, even though where msbuild returns 2019 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\vsdevcmd\core msbuild.bat

Solution: 2019 didnt have c++ tools intalled! even though the msbuild folder was there..?

Random fix test, path had extra \ coming from this screen: (this fix not needed in the end?) @REM Add path to MSBuild Binaries @REM if exist "%VSINSTALLDIR%\MSBuild\Current\Bin" ( if exist "%VSINSTALLDIR%MSBuild\Current\Bin" ( @REM set "PATH=%VSINSTALLDIR%\MSBuild\Current\Bin;%PATH%" set "PATH=%VSINSTALLDIR%MSBuild\Current\Bin;%PATH%" ) else ( set /A __VSCMD_msbuild_failcount=__VSCMD_msbuild_failcount+1 )

delete build/ folder, it was generated when had that version installed?

"D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat" The input line is too long. The syntax of the command is incorrect.

In my case it was caused by the PATH environment variable being too long. The errors were solved after removing some unnecessary lines from PATH. https://intellij-support.jetbrains.com/hc/en-us/community/posts/360009001580-I-can-not-build-CUDA-project

No CUDA toolset found.

install cuda, i used 11.4

-- The CUDA compiler identification is unknown, Failed to detect a default CUDA architecture.

(doesnt fix it) set TCNN_CUDA_ARCHITECTURES=86 delete old build/ folder (but doesnt fix it)

if added "set TCNN_CUDA_ARCHITECTURES=86", then error "CMAKE_CUDA_ARCHITECTURES must be valid if set"

delete old build/ folder (but doesnt fix it) install older version of CMAKE 3.22.5

No CMAKE_CUDA_COMPILER could be found

copying these files from extracked cuda installer temp folder didnt help, and the files were already there mitsuba-renderer/mitsuba2#103 (comment)

add this to CMakeList.txt

set(CMAKE_CUDA_COMPILER "D:/sdk/CUDA/bin/")

CUDA_ARCHITECTURES is empty for target "cmTC_5d02e"

downgrade to cmake 3.21, doesnt help

"I managed to correct this issue by fully uninstalling Visual Studio and CUDA and reinstalling both on the system drive without changing the installation path" NVlabs/instant-ngp#461 (comment) *im using d: drive path

Please verify the CUDA Toolkit is installed properly or define the CudaToolkitDir property to resolve this error

these variables are empty? since the props was copied from temp, not yet set? Text="CudaToolkitDir : '$(CudaToolkitDir)'" />

if set in cmd, set CudaToolkitDir="D:/sdk/CUDA/bin/" then other errors

can set it manually in cmake.txt, but then error:

note its wrong msbuild, Failed to run MSBuild command: d:/Program Files/Microsoft Visual Studio/2022/Community/MSBuild/Current/Bin/amd64/MSBuild.exe to get the value of VCTargetsPath:
