Can't compile Mitsuba3 on Windows 10

[aantg]

Hello!

I want to use double precision render variants. As they are not there by default, I have to compile Mitsuba myself. Based on relevant topic in documentation I followed steps below:

1. git clone --recursive https://github.com/mitsuba-renderer/mitsuba3 --branch v3.5.2

2. cmake -G "Visual Studio 17 2022" -A x64 -B build -DMI_ENABLE_EMBREE=0

Command output

cmake -G "Visual Studio 17 2022" -A x64 -B build -DMI_ENABLE_EMBREE=0

3. Modified enabled variants list in mitsuba.conf file:

Modified list

    "enabled": [
        "scalar_rgb", "scalar_rgb_double", "cuda_ad_rgb", "cuda_ad_rgb_double"

4. Opened mitsuba.sln, changed configuration to Release, pressed Build Solution and build process failed after a while with lots of warnings and link errors LNK2001:

I also tried steps from documentation as-is (except that I cloned with --branch v3.5.2) and had no luck.

My configuration:

• Windows 10
• Visual Studio 2022 (Community Edition) Version 17.11.5 (Classic C++ Applications development task installed)
• cmake 3.30.5 (64bit)
• git 2.44.0 (64bit)
• Python 3.11.8 (64bit)

Where is my mistake? What should I do to successfully build Mitsuba? Also after that I would like to add Mitsuba to my python virtual environment, how to do it in a better way?

Hi @aantg

If you combine v3.5.2. with the default set of variants. Do you still get the error message?

I think you might have a mitsuba package already installed on your system. Uninstall it before trying to compile the project yourself.

Hello.

If you combine v3.5.2. with the default set of variants. Do you still get the error message?

Can't compile with the default set of variants either.

I think you might have a mitsuba package already installed on your system. Uninstall it before trying to compile the project yourself.

I pip installed mitsuba inside virtual environments. Don't think this installs should be visible outside.

May it be because of some missed component(s) of Visual Studio, which development task should be installed? I also have VS2019 installed may there be some conflicts?

[njroussel]

I checked our CI, it's running the exact MSVC compiler verisons as you.
I have no idea of what is going on

@aantg Instead of building from Visual Studio, could you try something like this from the terminal?

cmake --build build --config Release -j

where build is your build Directory where the CMake configure step was run.
