[SOLVED] atom cannot start because libgtk-x11-2.0.so.0 is not found, but ldd can locate it

Hi everyone!

I've installed Atom editor on my Crunchbang VM. Atom depends on libc6>=2.15, but the stable Waldorf has libc6 2.13, so I had to set up dynamic linking as described here

After that, I get another issue trying to run atom:

Code:

andrey@crunchbang:~$ atom
andrey@crunchbang:~$ /usr/share/atom/atom: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

,which is strange, because the library is there and ldd can find it too:

Code:

andrey@crunchbang:~$ locate libgtk-x11-2.0.so.0
/usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0
/usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0.2400.10
/usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0
/usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0.2400.10
andrey@crunchbang:~$ ldd /usr/share/atom/atom 
...
	libgtk-x11-2.0.so.0 => /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0 (0x00007fef7aba6000)
	libgdk-x11-2.0.so.0 => /usr/lib/x86_64-linux-gnu/libgdk-x11-2.0.so.0 (0x00007fef7a8f3000)
...

There is plenty of similar questions on LQ and on the web, but most of them were solved by installing libgtk (which I already have). I have also checked that symbolic link /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0 correctly points to /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0.2400.10, and even installed i386 version which seemed to help some people with their programs. Nothing helped so far, and I'm at a dead end here.

By the way, when I simply upgraded libc6 from the testing branch, I was able to run Atom right away without problems. However, the upgrade also broke my locale program and who knows what else, so I don't want to go the unstable way anymore.

Any ideas how to solve this? Thanks a lot!

Sounds like there has been a code change since libc6 2.13 which is needed and libc6 2.15 (or greater) has the necessary routine. Run 'ldd' on 'atom' to check its dependancies. See if libc6 2.15 has been backported(?).

ldd does say that required library is not found:

Code:

andrey@crunchbang:/opt/pycharm$ ldd /usr/share/atom/atom 
/usr/share/atom/atom: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by /usr/share/atom/atom)
/usr/share/atom/atom: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by /usr/share/atom/libchromiumcontent.so)
/usr/share/atom/atom: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by /usr/share/atom/libgcrypt.so.11)
/usr/share/atom/atom: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by /usr/share/atom/libgcrypt.so.11)

Atom also used to show similar message before I "patched" it as described in the mentioned GitHub comment, but now doesn't. I guess ldd simply can't know that newer version of libc is linked dynamically when Atom is run, hence the "not found" error.

Looks lke the issue is not with libc6, but with libgtk.

Turned out, it was my mistake. Details are not very clear to me, but apparently this dynamic loader uses separate ld.so.conf from the directory where libc6 2.19 resides, and I should've inserted the paths from /ect/ld.so.conf.d/*.conf files there. It's described in the instruction, I've just misunderstood the step.
