Bug report

• AirSim Version/#commit: git clone https://github.com/Microsoft/AirSim.git
• UE/Unity version: 4.25.4
• autopilot version: N/A
• OS Version: N/A

What's the issue you encountered?

I do like this, everything is well before I run the command ./build.sh.

I think it's the cmake error

but I don't know how to solve this.

Thans!

Seems to be a linker error from the line - usr/bin/ld: 找不到 -lstdc++ Try installing libstdc++-8-dev package and run the script again

I have done this, too.

I think the last package is about ROS, so I didn't install it.

[wq1148927746]

However, it is still error.

[wq1148927746]

I encounter another problem about GPU.

When I try to run UE, There was a mistake, too.

Maybe this is related to the settings of GPU?

However, I can use GPU in PyTorch. And nivdia-smi is perfectly normal.

But, the bar of graph in setting displays as follows:

I am new to ubuntu and GPU.

Thank you!

[wq1148927746]

I use a GPU of nvidia 3060TI

[nikhil-sethi]

What kernel version are you using @wq1148927746? There are known GPU issues with an AMD-Nvidia configuration. I have a similar configuration and a lot of the gpu issues were resolved after 5.6-5.7 kernel versions. Also, in my case the 'llvmpipe' was showing when I had Nvidia-optimus enabled in the BIOS. Try setting it to only the dedicated GPU option and see if it changes.

Thanks! I solved this problem. But I still error in ./build.sh.

[lovettchris]

This solved the problem for me:

sudo apt-get install libstdc++-8-dev

I see this in the setup.sh so I'm not sure what that didn't work, but running it manually fixed the build.
