Re: [SOLVED] steam: missing libc.so.6

Yep, totally weird.  I am logged in with user lllars, which is my normal everyday user and this is my normal everyday computer.  I run other programs which are located in subdirectories of /home/lllars/ all the time.  Here is the output of my /etc/fstab:

# 
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
shm                    /dev/shm      tmpfs     nodev,nosuid        0      0
/dev/sda2 / ext4 defaults,relatime 0 1
/dev/sda5 /home ext4 defaults,relatime 0 1
/dev/sda6 swap swap defaults 0 0

/dev/sda1	/win	auto	user,noauto	0	0

none /proc/bus/usb usbfs auto,busgid=108,busmode=0775,devgid=108,devmode=0664 0 0

Agreed that this doesn't seem like a steam bug, but rather just that something is a little strange with my computer.  I don't know what else could cause a permission denied error.  As I said before I even tried to run it as root, and still got premission denied.

Also, as I said before, I've experienced a similar problem with xampp, which I traced back to the script trying to run the following (another permission denied error):

lllars ~ $ ls -l /opt/lampp/bin/php-5.4.7 
-rwxr-xr-x 1 root root 10216136 Sep 30  2012 /opt/lampp/bin/php-5.4.7
lllars ~ $ /opt/lampp/bin/php-5.4.7 
bash: /opt/lampp/bin/php-5.4.7: Permission denied
lars ~ (1) $ su
Password: 
root /home/lllars # /opt/lampp/bin/php-5.4.7 
bash: /opt/lampp/bin/php-5.4.7: Permission denied

Any ideas about what else could cause such an error would be appreciated

https://wiki.archlinux.org/index.php/fstab

i'm not really an expert, but take a look at the options, maybe adding the "exec" option for the /home ... however the "default" should contain the exec option for ext4, but ... lampp is on your root partition and same issue. weired indeed... maybe try lsattr <filename> on those files, but i don't know of any attributes that forbids execution, but maybe we can see something ...

Also try to post this issues permission/libc issue under a different category of the forum, like System administration here: https://bbs.archlinux.org/viewforum.php?id=50 and refer to this forum, maybe someone with more experience will see the topic and find a solution for this.

Re: [SOLVED] steam: missing libc.so.6

Looking at /usr/bin/ldd on my system, that error message ("not a dynamic executable") gets printed if:

1) RTLDLIST is empty in /usr/bin/ldd,
2) None of the items in RTLDLIST are executable, or
3) Every item in RTLDLIST returns 1 (check with 'echo $?') when run as "$rtld --verify path/to/steam"

On my system, RTLDLIST is "/usr/lib/ld-linux.so.2 /usr/lib64/ld-linux-x86-64.so.2 /usr/libx32/ld-linux-x32.so.2", and running "/usr/lib/ld-linux.so.2 --verify steam" returns status 0, which is success.

Which of those steps is failing on your machine?

Re: [SOLVED] steam: missing libc.so.6

Solved!  Holy smokes this actually got fixed!!

There was a problem with my /usr/lib/ld-linux.so.2.  It was pointing to ld-linux.so.2.old.  I'd guess I probably did this long ago as a jury-rig solution to some since forgotten problem.

lllars ~ $ ls -l /usr/lib/ld-linux*
lrwxrwxrwx 1 root root     17 Nov  9 13:39 /usr/lib/ld-linux.so.2 -> ld-linux.so.2_old
-rw-r--r-- 1 root root 149345 Mar  1  2012 /usr/lib/ld-linux.so.2_old
lrwxrwxrwx 1 root root     10 Oct 25 11:29 /usr/lib/ld-linux-x86-64.so.2 -> ld-2.18.so

Interestingly, after removing the bad link, and then having pacman re-install lib32-glibc, it recreated the bad link.  The solution was to remove both the bad link, and ld-linux.so.2_old, and then reinstall lib32-glibc:

lllars ~ $ sudo unlink /usr/lib/ld-linux.so.2
lllars ~ $ sudo mv /usr/lib/ld-linux.so.2_old ./ 
lllars ~ (1) $ sudo pacman -S lib32-glibc
warning: lib32-glibc-2.18-10 is up to date -- reinstalling
...(full output not copied here)...
lllars ~ $ ls -l /usr/lib/ld-linux*
lrwxrwxrwx 1 root root 22 Nov  9 09:55 /usr/lib/ld-linux.so.2 -> ../lib32/ld-linux.so.2
lrwxrwxrwx 1 root root 10 Oct 25 11:29 /usr/lib/ld-linux-x86-64.so.2 -> ld-2.18.so

I actually stumbled upon this solution on my own.  I was taking LyCC's advice of posting in the sys admin section.  While typing up the post, I realized I should confirm that I can run some 32-bit programs.  I knew I'd run some in the past, but couldn't bring any to mind, so was googling around for an example of a 32-bit program to run in Arch.  One of my search results was this thread, detailing someone trying to run skype but missing an ld-linux link: https://bbs.archlinux.org/viewtopic.php?id=145568

Thanks everyone for the help.  ColdPie, it looks like your post would have quickly led me to the solution, had I not been stumbling onto it at the same time you were writing.

Re: [SOLVED] steam: missing libc.so.6

Out of curiosity, how did you find that info ColdPie?  Looking through the source code for ldd? I see no mention of it in the man page.

ldd is a shell script, so "source code" is a bit of an exaggeration, but yeah. I often do that if I can't puzzle out what an error means, since reading the code often points to what /actually/ failed.

Re: [SOLVED] steam: missing libc.so.6

Today I had this problem after a power outage while Steam homepage was open on my screen. I tried:
- Reinstalling Steam
- Reinstalling lib32-glibc
- Deleting all Steam files (~/.steam, ~/.steampath, ~/.steampid, ~/.local/share/Steam)
- Checking if there is a slash at the end of $HOME
- Updating all my video drivers (AMD, open source)

None worked. Fortunately, I was able to solve it after about an hour trial and error. I did:

- Uninstall Steam and delete all of its files
- Delete libc.so.6 link in /usr/lib32 "sudo rm -rf /usr/lib32/libc.so.6"
- Reinstall glibc "sudo pacman -S glibc lib32-glibc"
- Reinstall Steam

Steam now works perfectly after these. I hope this helps someone else who couldn't solve it with other methods.

(I am new here, sorry for formatting mistakes)
