Portal not start on linux
- gentoo linux (but using steam-runtime)
- steam client updated today and portal installed today too
- installation verified
- play
- "unable to load filesystem_steam.so"

I can't find the library anywhere on my system... any help/udate/fix or someone with that library taken from other games?

Launching the game strace I can see that it's caused from a dlopen() system call (that's why using ldd on all the other libraries there's no static dependency on filesystem_steam.so)

Trying with the beta there's another error:
"not enough space for media/StartupVids.txt"
Launching the game with "-novid" option avoid the message, but the game crash after few seconds.

Thank's in advance

I don't think it supports Linux. According to the store page at least, I don't see it anywhere.

Well the game is installable on steam for linux, and there are native linux executables (no wine or whatever). Really hope that valve support one of his games on his own platform.

reinstalled a couple of time and still not start. On these last reinstall even with the beta it complain with the missing "filesystem_steam.so". Do you know how I can have support for this game? Thank's again in advance.

Portal worked fine on Fedora 19 -> 22 and I even finished the game, but after a disk crash, and re-installation on Fedora 23, I get this error, again. Looking at my backups, the filesystem_steam.so file didn't exist before the crash, either. afaict, it should work.

I was installing my games on a separate partition, /data/SteamGames/ and this prevented both Portal and Portal 2 from successfully launching. Installing the game under the default user home area ~/.local/share/steam/... solved the issue.

Likely, the issue lies with the steam launcher, and not the game itself. Someone forgot to include filesystem_steam.so in the package. :(
