Is it possible to build the PhysX in a wsl2 system that uses XMing for the GUI?

[shutengW]

Hi,

I am new to PhysX and I wonder if it is possible to build it in my WSL2?

I tried it and the following error pops:

./generate_projects.sh

Hi @shutengW did you look at our platform readme already? https://github.com/NVIDIA-Omniverse/PhysX/blob/release/104.2/physx/documentation/platformreadme/linux/README_LINUX.md

You will want to use preset 1 as well I would assume.

[shutengW]

Hi, Yes, I did have a look at it. I am pretty sure all the libs are installed. I did have used preset 1, and the error remains as shown below. And I am pretty sure all the packages are properly installed. So I am a little confused whether this could work out in my WSL2. Any hints would be really appreciated.

and fyi I installed gcc in my Ubuntu. I did not use clang..

gcc --version

It works by installing the clang compiler. I have figured this out. Thx. Although I am still not sure why gcc does not work...

[preist-nvidia]

Ok good, but yes I agree that gcc should also work.
