Build error after updating ubuntu about physx-rs HOT 7 CLOSED

UPDATE I cloned the project and tried to build it, same error. I'm not sure it can be build on newest ubuntu anymore.

from physx-rs.

Installing g++-11 and running export CXX=g++-11 fixed it

from physx-rs.

Can this be moved to somewhere else? would be nice having it up so someone else might see it, so I'm not closing the issue.

I'm going to guess export CXX=g++-11 isn't the important part; rather that installing g++-11 also installed libstdc++ which you were missing.

I have that library but I'm unsure of what the problem actually is. I've read that the ciso646 header is unavailable in c++ greater than 17...I've literally installed all versions of clang and g++ now, and I could only find this header in include/c++/9 or 11..I'll have to double check when I get - home, also I'm a c++ novice, I'm not familiar with the eco system so it's possible that I messed something up along the way. All I know is I upgraded to Ubuntu 22 and the build broke..so it might happen to others as well

I resolved it somehow but I'm not sure how, after 12 hours of installing packages and compilers it suddenly worked.

@tgolsson @mlp1802 solution for me was:
sudo apt install libc++-11-dev
export CXX=g++-11
