Description Stevan White 2003-06-10 09:33:32 UTC
Version:           2.1.5 (using KDE KDE 3.1.1a)
Installed from:    Mandrake RPMs
OS:          Linux

It looks like there's a problem building KDevelop that renders it useless when installed from distro rpm's.

This occurs in several linux distros (at least Redhat and Mandrake... do a Usenet search for 'kdevelop qt-mt'), so I'm reporting it here in the hope it can be fixed so it won't recur in the future.  Work-arounds have been proposed but they involve compiling and linking KDevelop.

Create a new project.  In wizard, leave everything as default, except to specify a project name.  Fails with following errors:
-----------------------------------------------------
shell-init: could not get current directory: getcwd: cannot access parent directories: No such file or directory
shell-init: could not get current directory: getcwd: cannot access parent directories: No such file or directory
configure: error: Qt (>= Qt 3.0.3) (library qt-mt) not found. Please check your installation!
For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!
warning: HermesView inherits unknown class 'QWidget'
warning: HermesDoc inherits unknown class 'QObject'
warning: HermesApp inherits unknown class 'KMainWindow'
-----------------------------------------------------

I have checked: /usr/lib/qt3/lib contains libqt-mt.so.3.1.2 and a link to it named libqt-mt.so, and /usr/lib/qt3/lib is listed in /etc/ld.so.conf.


From distro rpms, I had previously upgraded my KDE to 3.1.3a. Since finding this problem, I have upgraded KDevelop to build 2.1.5-5mdk, to no avail.

More info:

Work-around:  Allow project creation to fail, then under
"Project->Options...->Compiler Options->Linker Flags", in Additional flags, put

     -L/usr/X11R6/lib -L/usr/lib/qt3 -lGL -lXmu -lXrender -lXft -lXext -lX11
-lSM -lICE -lXt

Got idea from config.log file.  It seemed to indicate the problem wasn't really
with finding qt3, or with the qt-mt library, but with finding libraries
referenced by qt-mt.  

I think I've seen this before.  Maybe has something to do with new gcc?

 -L/usr/X11R6/lib -lXmu -lXrender -lXft -lXext -lX11 -lSM -lICE -lXt

works as well
Comment 3 Thiago Macieira 2003-06-10 15:17:24 UTC
This does not appear to be a KDE/KDevelop bug at all. Please report to the 
distributions' bug tracking systems. 
 
Besides, KDevelop 2.x is no longer being developed. Please upgrade. 
Comment 4 Stevan White 2003-06-10 22:23:34 UTC
KDevelop 2 is being distributed.  There are lots of people reporting the same
problem on the net.  Surely a bugfix could be released.

If you feel that this isn't your problem, please tell me whose problem it is, so
I can report it to them.

The bug in KDevelop is that it reports that libqt-mt cannot be found, although
in fact it has found that library.  In fact, the test it runs is to attempt to
link it with gcc, and this test fails because it has failed to link in other
libraries needed by libqt-mt.

As far as upgrading is concerned, I'll wait until my distro releases an rpm, but
thanks for the advice!
Comment 5 Thiago Macieira 2003-06-11 01:29:17 UTC
I'm not part of the KDevelop team, so I won't close this bug again. But I'm sure they 
have already closed bugs with messages "KDevelop 2.x is no longer developed 
and no further patches to it will be released". 
 
As for your problem, does it only happen with installed RPM packages? If you 
install from source it doesn't happen? If that's the case, then it's most surely a 
packaging bug (= report to your distribution), not a KDE bug. 
Comment 6 Harald Fernengel 2003-06-11 11:05:59 UTC
Mandrake updated the compiler and the auto* tools to versions that are incompatible with 
KDevelop 2.x. KDevelop 2.x is a KDE 2.x product designed to develop KDE 2.x apps and has 
been patched to also support KDE 3.x. Please understand that the development team is too 
small to support two branches _and_ several distros, especially when they put the newest stuff 
on the DVDs without checking that the old stuff still works. 
Check KDevelop 3.x, if you don't like it, you can create a new project with it and import it as 
custom project in KDevelop 2.x, that should work. 
At least SuSE has some entries in their knowledge base how to make KDevelop work with SuSE 
8.x, you might want to check if your distro has something similar. 
Comment 7 Stevan White 2003-06-12 03:41:17 UTC
OK, I'm convinced this would be more effectively treated as a bug with version
choices in package dependencies than with KDevelop itself, so I'll leave it closed.

Mandrake knew about this well before the latest release.  I have to think they
could have done something.
    http://qa.mandrakesoft.com/show_bug.cgi?id=1751

However, it isn't just a Mandrake issue  Red Hat people are reporting the same
problem.

This isn't a very good way to handle bug reports on different branches.  Instead
of pooh-poohing, then closing, reports about a (widely-distributed) branch on
the grounds that the branch no longer has your interest, it would be better to
have two branches for bug reports, with an automatic message for bug reporters
to the effect that a branch isn't being actively developed.  That way, valid
reports of problems that have not been resolved won't get marked RESOLVED INVALID.
