Support GPU version for Windows #10

Closed flferretti closed 7 months ago

Solution to issue cannot be found in the documentation.

Issue

With #9 we tried to add GPU support for warp, yet the Windows builds fail with:

nvcc fatal   : Could not set up the environment for Microsoft Visual Studio using 'C:/Program Files/Microsoft Visual Studio/2022/Enterprise/VC/Tools/MSVC/14.29.30133/bin/HostX64/x64/../../../../../../../VC/Auxiliary/Build/vcvars64.bat'

This might be due to the fact vcvars64.bat appends values to PATH each time it is called, making the PATH too long to be processed by nvcc. As a result, when trying to compile main.cu, the error reported above is raised

Adding:

set NVCC_APPEND_FLAGS="%NVCC_APPEND_FLAGS% --use-local-env"

to the build script on Windows should solve the problem, see https://github.com/conda-forge/colmap-feedstock/pull/38#issuecomment-2022414291 and https://github.com/conda-forge/nvcc-feedstock/issues/76 .
