Agree re ubuntu not being the last word on things. OP wants a cross-platform dev environment though. If a platform that is primarily for free unix is obviously broken on a major linux distro, it's a bad omen for its multiplatform prospects.
Yeah, or it's a bug that needs to be filed with the relevant authority.
There are honestly a lot of major linux distros now.
If your cross-platform environment's users are all Gentoo, Fedora, NixOS, Exherbo, Arch Linux, your own homebrew distro, and some OSes with another kernel(s), you may have really achieved cross-platform support without finding Ubuntu support.
My favorite cross-platform project supports Ubuntu, but is lacking Fedora support. It was a major stumbling block for me (just one day), but the dependencies are nothing special, you can compile libuv and libgmp, ncurses, openssl, and libsigsegv pretty much anywhere that I care about (Mac, Linux, BSD).
The only time it mattered for me is when I've got half an hour to give a presentation and the audience is supposed to compile and install the stuff I'm using, but unexpectedly found to be using Fedora and I don't know what packages to tell them to get.
