symbol lookup error

[Bernard François]

Binary package hint: subcommander

When I start subcommander, nothing happens (no window opens).

When I start subcommander from the command line, I get the following output:

ber@ubuntu:~$ subcommander
subcommander: symbol lookup error: /usr/lib/libQtNetwork.so.4: undefined symbol: _ZN14QObjectPrivate15checkWindowRoleEv

I just renamed the settings folder in my home directory (.subcommander), but that didn't change anything. The output remains the same.

I just read the following on the site of subcommander:

> 2.0.0 has reached a point with beta 4 where it is better than 1.2. Moving to Qt4 is not finished but the biggest part (working copy view & repository view) is done.

As the error message is related to Qt, I guess the solution is to wait until there's a better version. I think this beta version should not have been in the ubuntu repositories (especially if the author explained that it's still work in progress).

I will uninstall subcommander and compile the 1.2 version myself.

For anyone interested in a workaround; I just managed to install subcommander 1.2. It was a rather tedious process, so here's a description of what I had to do:

1) remove subcommander using synaptic

2) download subcommander 1.2 from the site:
http://subcommander.tigris.org/servlets/ProjectDocumentList?folderID=2886&expandFolder=2886&folderID=2885

3) create a backup of the .subcommander directory in your home directory (if you want to continue working with previous settings)

4) install the following packages (over 100MB here):
libapr1-dev
libaprutil1-dev
libboost1.35-dev
libsvncpp1
libneon27-dev
libqt3-mt-dev

5) run the configure script in the directory from the archive (had to look at the source of the configure script to figure out which directory needed to be passed):
./configure --with-subversion="/usr"

6) create a symlink by issuing the following command:
ber@ubuntu:/usr/lib$ sudo cp -l /usr/lib/libsvn_ra_neon-1.so.1 /usr/lib/libsvn_ra_dav-1.so
This step is necessary to avoid a linking error (see https://bugs.launchpad.net/ubuntu/+source/subversion/+bug/286754).

7) compile by calling 'make'

8) install by calling 'sudo checkinstall' ('sudo make install' will work as well, but then you can't uninstall the package using synaptic / apt-get)

9) if installed with checkinstall, make sure to lock the subcommander package, so it's not upgraded automatically again to v2.0 (by selecting the package and using 'Lock Version' in the 'Package' menu).

10) remove the .subcommander directory in your home folder, and put the original .subcommander directory back in place (just overwriting the directory didn't work)

11) run the following command to avoid an error message being displayed when running subcommander:
sudo chmod +r /etc/qt3/qt_plugins_3.3rc
(clue found at http://forum.kde.org/qsettings-failed-open-file-etc-qt3-qt-plugins-3-3rc-t-31383.html)

12) run subcommander

13) in case you did restore your old .subcommander directory, and/or the graphical diff tool is not working, you need to go to the "Tools > Settings... > Diff/Merge" menu, and press the 'reset/builtin' buttons
(clue found at http://subcommander.tigris.org/issues/show_bug.cgi?id=187)

After this, I can finally succesfully run and use subcommander again!
