[Bug 660257] [NEW] linking fails with binutils 2.20.51.20101009-0ubuntu1: cannot use --sysroot

Public bug reported:

Binary package hint: ghc6

I am using the ghc6 package version 6.12.1-13ubuntu1 on Natty Narwhal:

ghc no longer works:

Apparently, --sysroot is disabled in the newer binutils:
https://bugs.launchpad.net/ubuntu/+bug/598389

I don't know whether this is a problem that should be resolved in GHC or
in binutils.

Let me know if I should provide more information.

Thanks!

The bug has been reported and fixed upstream:

   http://bitbucket.org/rg3/youtube-dl/issue/164/youtube-dl-20100714
-does-not-download

I hope to see the patch in Ubuntu soon.

Thanks for maintaining the package!

[Bug 286906] Re: Unable to use libmozjs.so in an application, because of library path problem.

[Miciah Dashiel Butler Masters]

I work on the ELinks Web browser ().  ELinks has
(presently very minimal) support for ECMAScript via SpiderMonkey, so
this issue affects ELinks as well.

Until recently, I had been building ELinks with libmozjs1d and libmozjs-
dev.  However, xulrunner-1.9.1, on which firefox-3.5 depends, conflicts
with libmozjs-dev.  In order to be able to update to the latest release
of Firefox, I have changed ELinks to be compatible with the new
interfaces in the new xulrunner, and I have manually added some symlinks
(/usr/lib/libmozjs.so -> xulrunner-1.9.1.1/libmozjs.so and
/usr/include/mozjs -> xulrunner-1.9.1.1/unstable).

ELinks's ECMAScript support is optional, and Ubuntu's ELinks package
does not enable it, although Debian's does, and my own build does, so
this issue with ELinks does not necessarily cause another bug in Ubuntu,
but it is inconvenient for me and anybody else who wants to enable
ECMAScript in ELinks on Ubuntu.

Please let me know how the ELinks project should proceed to maintain
compability with Ubuntu.  Many thanks!

[Bug 398416] Re: Window gets white after some time

[Miciah Dashiel Butler Masters]

I confirm the issue with Gwibber running with the Awesome window
manager.  I also confirm that the patch resolves the issue.  Thank you!

BTW, FYI, BBQ, Awesome itself handles notifications: the C code allows
the Lua code to interface with D-BUS, and notifications are handled by
the Naughty library (cf. /usr/share/awesome/lib/naughty.lua).  No
notification daemon is required with Awesome.

[Bug 344163] Re: Default config uses bad check_mail setting.

[Miciah Dashiel Butler Masters]

If no spool file is set, the check_mail feature also causes multitail to
wake up every 10 milliseconds.

This bug is easily verified using strace(1) or powertop(1):

1. unset the MAIL environmental variable (e.g. using `env -u MAIL`);

2. run multitail with the default setting of 'check_mail:5' in
/etc/multitail.conf; and

3. use strace or powertop to see that multitail wakes up every 10ms
because of timeout on select(2).

4. Then add 'check_mail:0' to ~/.multitailrc;

5. run multitail again; and

6. use strace or powertop to see that multitail calls select(2) without
a timeout.

The concerned routines are wait_for_keypress in mt.c and
do_check_for_mail in misc.c.  wait_for_keypress contains the select(2)
loop for multitail.  It also calls do_check_for_mail in every iteration
of the select(2) loop.  wait_for_keypress checks msf_last_check in
computing the time until the mail next needs to be checked, and it uses
this time as an upper bound for the timeout for the select(2) call.
do_check_for_mail is supposed to reset msf_last_check to the current
time whenever it checks mail.  The problem is that if mail_spool_file is
NULL, do_check_for_mail returns immediately.  Thus msf_last_check is
never updated, and wait_for_keypress always gives select(2) a very short
timeout.

Should I open a separate bug report regarding the excessive wakeups?  I
have a patch for this issue.

[Bug 285591] Re: paprefs versioned dependency on libpango1.0-0 is outdated

[Miciah Dashiel Butler Masters]

It appears that Launchpad lost my description of the problem, so I'll
rewrite it and hope that it doesn't appear twice.

My laptop runs Ubuntu Intrepid.  I installed the newest version of
paprefs, version 0.9.6-2ubuntu1:

   % apt-cache policy paprefs
   paprefs:
 Installed: 0.9.6-2ubuntu1
 Candidate: 0.9.6-2ubuntu1
 Version table:
*** 0.9.6-2ubuntu1 0
   900 http://us.archive.ubuntu.com intrepid/universe Packages
   100 /var/lib/dpkg/status
0.9.6-2 0
   500 http://ftp.us.debian.org sid/main Packages

paprefs failed to run:

   % paprefs
   paprefs: symbol lookup error: /usr/lib/libpangocairo-1.0.so.0: undefined 
symbol: cairo_has_show_text_glyphs
   zsh: exit 127   paprefs

I had an old version of libpango1.0-0:

   % apt-cache policy libpango1.0-0
   libpango1.0-0:
 Installed: 1.21.6-1
 Candidate: 1.22.0-0ubuntu1
 Version table:
1.22.0-0ubuntu1 0
   900 http://us.archive.ubuntu.com intrepid/main Packages
*** 1.21.6-1 0
   100 /var/lib/dpkg/status
1.20.5-3 0
   500 http://ftp.us.debian.org sid/main Packages

So I upgraded to the newest version of libpango1.0-0, version
1.22.0-0ubuntu1:

   % apt-cache policy libpango1.0-0
   libpango1.0-0:
 Installed: 1.22.0-0ubuntu1
 Candidate: 1.22.0-0ubuntu1
 Version table:
*** 1.22.0-0ubuntu1 0
   900 http://us.archive.ubuntu.com intrepid/main Packages
   100 /var/lib/dpkg/status
1.20.5-3 0
   500 http://ftp.us.debian.org sid/main Packages

Then paprefs ran fine.

paprefs has a versioned dependency on libpango1.0-0 version 1.21.3:

  % apt-cache show paprefs|grep Depends:|grep -om1 'libpango1.0-0[^,]\+'
  libpango1.0-0 (>= 1.21.3)

Apparently, this dependency must be updated.

Thanks,

[Bug 64590] Re: Mistakes in elinks strings

[Miciah Dashiel Butler Masters]

Malcolm Parsons,

Your patch was posted to the ELinks Bugzilla:
.  I would like to commit
it to the upstream repository.  How shall I credit you in the AUTHORS
file?  Your E-mail address is not listed on Launchpad; would you prefer
just your name, or could you tell me (on Launchpad, on IRC, or via
E-mail) your E-mail address?
