Build failed in Linux, VSCode

[Napat-Osaka]

I am trying to build Falcon following the readme for Linux. Half way through the build the following error appeared. This is a fresh clone from Git, I already ran setup.sh, and VSCode is the newest version. Ubuntu version and GPU model should also be in order as well.

The following is from cmake, just the default preset switch as the readme said to

Any advices to the right direction would be highly appreciated.

We only tested this on Ubuntu 22.04 LTS with gcc. Specifically for USD you need to compile with gcc.

Thanks for the reply ! Ubuntu version should be just about right.

Sorry for such a newbie question but can you elaborate more on how can I set it up to compile with gcc ? I thought I already doing so after I changed the preset to Linux/GCC, or do you meant CXX_COMPILER must also change from g++ -> gcc ? I tried that just in case but no luck. I also tried switching gcc versions (10-11-12), with not much success either.

Using the Linux/GCC preset is all that should be needed actually. Not sure why you see the compilation errors. The CI on github does build the Linux/GCC successfully. I'll retrigger a build to see if that's still the case.

@skallweitNV Hi, can you replicate the same error on your side ? I would really loved to get an update even if that is the case and there is something wrong with the setting on my machine.

I have updated the CI config and ran a Linux/GCC build on GitHub. It works fine.
