Adding New Linux Libraries: Steam Client

Amzo

Amzo

I was playing about getting steam to work using the Linux binary emulation. Surprising enough. It only needs glibc 1.12; Which I used by setting up a custom Linux jail from Arch Linux rollback server. (Works great, I may add.)

However. I currently managed to get Steam to run, update and execute after initial bootstrapping. However the last issue I have with running Steam is the libraries Steam bootstraps. Which are saved in $HOME/.steam/. I can't get the binary to use these libraries.

Do libraries need to be branded as well? brandelf -t linux Or do you need to add that path to Linux ldconfig? /compat/linux/sbin/ldconfig -r $HOME/.steam/ Well either way I'm having a tough time getting it to find its libraries. Even setting LD_CONFIG_PATH.

Anyone have any ideas?
 
Well I finally got it to detect the libraries, but it hangs. I think this is probably due to the system calls not being implemented:

Code: 
+ ./steam

Looks like steam didn't shutdown cleanly, scheduling immediate update check

Patches for the needed system calls are:

http://lev.vlakno.cz/~rdivacky/patches/linux_epoll.patch

So I'll try again later on, with the epoll patch.
 
Well unfortunately, when I compile with the patch, I'm giving the following errors when trying to kldload linux (after a reboot into the new kernel of course):
Code: 
exec format error

I'm not sure of the issue of this yet, as the module loads when I recompile the kernel and all modules without the patch. So I'm pretty much stuck at a dead end until I can solve that.

I also doubt it will ever be in ports as of yet. It needs a custom Linux base in /compat/linux, the kernel will possibly need patching (may already have the system calls implemented in 10).
 
TF2 Dedicated server

[size=-1][Separate thread merged in. -- Mod][/size]

Hello, I want to know if I need to install something special to make a dedicated server for Team Fortress 2. I mean what software I need to make it run nice beside of FreeBSD of course.
 
Re: TF2 Dedicated server

Hello,

I've patched the kernel of FreeBSD 10.0-PRERELEASE r260296M by epoll patch and fixed all compile errors. I also fixed the kqueue() call in linux_epoll_create(). But there is another problem: Steam updates itself and next starts saying:
Code: 
Fatal Error: Failed to load libsteam.so
In dmesg I see:
Code: 
linux: pid 1125 (steam): syscall eventfd2 not implemented
According to amd64/linux32/linux32_dummy.c, eventfd2() was added in Linux-2.6.27 and it's not implemented in the Linuxator yet.

Steam found libsteam.so:
Code: 
linux_open("/lib/libsteam.so",0x0,013)		 = 8 (0x8)
read(8,"\^?ELF\^A\^A\^A\0\0\0\0\0\0\0\0"...,512) = 512 (0x200)
linux_fstat64(0x8,0xffff9658,0x282d1fc4,0x0,0x82fd280,0x6) = 0 (0x0)
linux_mmap2(0x0,0x344a40,0x5,0x802,0x8,0x6)	 = 735055872 (0x2bd01000)
linux_mmap2(0x2c02f000,0x15000,0x3,0x812,0x8,0x6) = 738390016 (0x2c02f000)
linux_mmap2(0x2c044000,0x1a40,0x3,0x32,0xffffffff,0x6) = 738476032 (0x2c044000)
close(8)					 = 0 (0x0)
munmap(0x2af84000,16605)			 = 0 (0x0)
munmap(0x2bd01000,3426880)			 = 0 (0x0)
but I don't know why it couldn't load it.

Hello, could you please explain in detail how you even get that far? If I download the client from here (unpackaged):

https://developer.valvesoftware.com/wiki/Steam_under_Linux

After extracting and executing the steam.sh script in my $HOME/.local/share/Steam/ directory, I only get:

Code: 
$ ./steam.sh
Error: Unsupported Operating System
./steam.sh: line 69: STEAMOS: unbound variable
