[gentoo-dev] Using new (masked) qt-x11-3.0.0 ebuild

[gentoo-dev] Using new (masked) qt-x11-3.0.0 ebuild

[Dan Armak]

Hi all,

Due to requests by developers of qt3 apps, I have committed a (masked) 
x11-libs/qt-x11-3.0.0 ebuild and accompanying files.

It's masked because portage doesn't (yet) have the right dependency 
specification functionality. If I say DEPEND=">=x11-libs/qt-x11-2.2", 
qt-x11-3.0.0 will be used if available. Someday someone will add this 
functionality, the deadline being the release of KDE3 around Feb. 2002. 
(Please do it earlier though!)

So if you just emerge this masked ebuild, portage will think it 
fullfills dependencies of qt-2.x and set QTDIR so that kde2/qt2 apps won't 
compile (or emerge).

Temporary fix: rename or move the directory /usr/lib/qt-x11-3.0.0 to some 
other location, e.g. /usr/lib/qt3. Then, kde2/qt2 apps will emerge correctly. 

To build things against your qt3 which is now in a non-standard location, 
copy the file /etc/env.d/45qt-x11-3.0.0 to e.g. /etc/env.d/45qt3 and update 
all paths in the new copy of the file. Then run env-update and relogin. That 
takes care of runtime dynamic linking. To compile against this qt (outside of 
portage), export QTDIR as appropriate or pass --with-qt-dir to your configure 
or whatever.

Hi,

I've installed the ebuild and tried to make it work correctly. I noticed
that qt3 has quite some font related problems. Reading the mailists on
trolltech.com, the only (temporary) solution is to disable the
anti-aliasing. During the configure phase I thus suggest adding
'-no-xft' until this matter has been resolved.

Additionally I also noticed that /etc/X11/XftConfig and
/usr/X11/lib/X11/XftConfig aren't the same file. Maybe the X
installation should be adapted to create a symlink from one to the other
instead.

Best regards,

I have problem with AA-fonts in Gtk+ 1.3 (what will be 2.0) after I
reinstalled my system to rc6. Does anyone else have these problems?

If you have this problem, which x11-base/xfree do you have?
Also, did you install this version from a clean system (ie not upgrading
X from an old version) if not, which version did you have installed
before?

I've noticed this too. Let's dig into this and find the problem, I spent
several hours this weekend trying to get Gtk+ 2 giving me AA-fonts but
didn't succeed (probably looking in the wrong places)...

I'm installed from scratch this weekend, so everthing is as new as it
could be, XFree 4.1.0 thus. The qt3 problem is not limited to gentoo,
I've had it too on Rocklinux and Redhat 7.2 and it's been acknowledge on
the Trolltech's mailinglist by several users. I guess this can only be
resolved by Trolltech in the next version. As a sidenote, AA works
perfectly with Qt2 and with the X test programs, thus in my case it has
nothing to do with the system.

Good luck, I hope you find it. I'm planning to have a look at GdkXft
soon to add AA support to Gtk 1.2.

Which X test programs do you mean? I tried xterm -fa and it works nice
on my system, but for some reason it doesn't work in Gtk+ 2. It works
however with the same Gtk+ on my other system (and worked before I did a
reinstall).

Ok, it should be easy enough.

Just x11perf and xterm -fa, nothing esoteric ;-)

It's strange that it doesn't work now anymore. I haven't got experience
with Gtk+2, so I can't help you much :-(

Hi,

I've put a new updated version of the ebuild on cv a little while ago. All 
installation problems should be resolved now. BTW, please contact me if/when 
you have any positive data on problems caused by my CXXFLAGS patch - I 
understand the font problems you talked about have been conffirmed as generic 
qt problems, and not my doing?

Hi,

about your CXXFLAGS patch, I'm not so sure I like it. It doesn't cause
any problems, but it's not according to the qmake specifications. During
compilation of qt -O3 and -O2 is both passed to gcc since the
optimization flags are put into another qmake flag. In fact to be really
correct, the CXXFLAGS should be parsed and each setting should be
assigned to the correct qmake flags (QMAKE_CC, QMAKE_CFLAGS,
QMAKE_CFLAGS_DEPS, QMAKE_CFLAGS_WARN_ON, QMAKE_CFLAGS_WARN_OFF,
QMAKE_CFLAGS_RELEASE, QMAKE_CFLAGS_DEBUG, QMAKE_CFLAGS_SHLIB and
QMAKE_CFLAGS_THREAD). I don't know however if it's worth the effort of
parsing the global CXXFLAGS. Another thought also crossed my mind, it
might be interesting to subdivide the build setting in make.conf in a
similar way and create the global CXXFLAGS out of finer tuning
variables. Don't know what you guys think about this, but imho it might
be interesting for at least qt and probably for other ebuilds. I think
this might be easy to add without creating an incompatible make.conf.

Yes, the font problems are not due to your doing, but I would definately
add the -no-xft switch until trolltech resolves this matter. Using xft
everything really looks horrible and imho unusable. This might then
again be removed when a next release of qt3 fixes the problem. Also
don't forget to update the 45qt-x11-3.0.0 file to use
/usr/lib/qt-x11-free-3.0.0 instead of /usr/lib/qt-x11-3.0.0.

Hm. Sounds intimidating :-) I suppose I'll remove the patch for now. BTW I've 
put a similar patch into the qt-2.3.2 ebuild, what do you think of that? I 
don't much mind what I do with the qt-3.0 ebuild, because you're almost 
certainly the only one who's using it right now.

You're right; I'll do that.

I've upated the ebuild to install into /usr/lib/qt-x11-3.0.0, so that the 
45... file is correct.

I don't think that with qt2 this can be a problem since it doesn't use
tmake or qmake globally while qt3 ships with qmake as its default build
system.
