Hi,
slackware 10.1 kernel 2.4.29
After I upgraded to dropline 2.10.0 from 2.8.3, xmms 1.2.10 will not open. The error I get is:
~:$ xmms unable to open port `/dev/ttyS1' (Permission denied) unable to open port `/dev/ttyS1' (Permission denied) *** glibc detected *** free(): invalid pointer: 0x4078bc79 *** Aborted
As su I get only the last line of the error about glibc
Dropline is the gnome version for slack.
How to resolve?
Am I correct in assuming that the call to xmms is from an xterm (not a console)?
I can't think of why a non-customized xmms startup might want to open a serial port ... something to do with lirc, perhaps? or displaying information to a LCD panel connected to a serial port? I'm really groping here... but that problem is surely just permissions for the non-root user. Check permissions with "ls -l /dev/ttyS1" and, probably, add the userid involved to the device's group. For example, on a stock Debian system, this command reports:
crw-rw---- 1 root dialout 4, 65 Mar 14 2002 /dev/ttyS1
So adding the userid to dialout (in /etc/group) would eliminate this error.
The other one is, probably, a bigger deal, suggesting a libc6 mismatch.Since dropline is a Slackware-specific customization of Gnome, it (naturally) isn't in the Debian packaging system, so I don't know the details of its dependencies (and I suspect the list on the Dropline Home Page is incomplete)... but I wonder if your install of it caused an update to libc6 (aka glibc), or some other change to the symlinks that involve libc6. Check the timestamps on whatever /lib/libc.so.6 is a symlink to, and on the symlink itself to see, if this happened. If it did, you may need to update xmms (I show the current Debian-Sid version as 1.2.10-2, requiring libc6 (>= 2.3.2.ds1-4), but these extraversion numbers tend to be VERY distro-specific, so you need to see what Slackware is actually doing here) to use a newer libc6. Or, depending on the details, you may need to fix the symlink. Or ... well, it depends on what you find, I suppose.
The Changelog for Dropline does include this line, Dated April 07 --
Updated to glib2-2.6.4-i686-1dl.tgz
-- which raises the possibility that this change in turn forced soe change to glibc (which is different from glib2, BTW, so don't get mixed up by the similarity of names).
(I ran into a similar problem recently involving a more specialized library. A Debian upgrade modified its symlinks, and because I had an old version of the library on the system, in addition to the current version, it made the symlink to the wrong version. Easy to fix once I tracked it down, but puzzling until I found the almost-duplicate library.)
Finally, take a look at the first "known issue" on this page:
http://www.dropline.net/gnome/support.php
Since I don't know the details of how you installed the prior version of Dropline, I don't know if it affected your install of xmms. But you'll want to think about whether this is relevant to your circumstances.
If you post again on this, please include:
complete output of "ldd /usr/bin/xmms"
complete output of "ls -l /lib/libc6*"(modified appropriately if I've guessed wrong about where Slackware puts xmms).
