[gentoo-dev] gcc and qt

[gentoo-dev] gcc and qt

[Pieter Breed]

Hi

I am just reporting two problems I had and what I did to fix it for me...

The gcc version that 'emerge world -u' tried to install (gcc-3.2.1-r6) does 
not contain/make the correct /usr/bin/gcc file.  The file is just not there 
after I merge it.  The version I have now that works is gcc-3.2.1-r1.  Even 
if I do a tar tjf on the .tbz2 file for the 3.2.1-r6 package it does not show 
/usr/bin/gcc...

The other thing is that the newest Qt (qt-3.1.1) breaks my mono-spaced fonts.  
I am not a font buff so I just mean 'all fonts where chars are of equal 
width'  Also it (obviously) only breaks fonts for programs (typically KDE) 
that uses the Qt font subsystem.  I say this because my gnome programs (like 
gvim) display these fonts correcty.  Also the other vairable width fonts are 
displayed correctly everywhere.  The version of Qt that I use now (and which 
does not have the problem) is qt-3.1.0-r1.  I friend of mine has a similar 
problem and the fix was the same too ..

regards
good luck on 1.4

Pieter,
Did you emerge QT 3.1.1 then reemerge the KDE libs? I don't know if this
is "overkill" but is it possible that would have fixed the situation?

I've seen quite a few people mention the surprise of emerging a new QT
lib, then having KDE break... I sort of assume this to happen since you
are changing the underlying lib, but maybe I am the one that is
mistaken.

I've done this so much now that I've not ever bothered to check if
emerge can detect this... i.e. I upgrade from 3.0 to 3.1 QT, does emerge
know that I should recompile my KDE libs? (base/lib, and annything else
important).

I wouldn't normally do this unless its required, as it takes so long :(,
so it would be great if emerge could suggest or warn me about it.

Any thoughts?

This shouldn't be necessary when upgrading from qt 3.1.0 to 3.1.1.

The most we can do with the current portage featureset, and have done, is emit 
a warning message after qt is emerged.

One thing is that freetype versions below 2.1.3 do not support compressed 
bitmapped fonts (pcf.gz) as available in stock xfree. The option so is to 
either upgrade, or to unpack those fonts. With the new qt it now uses 
fontconfig/xft2.

Please report a bug on bugs.gentoo.org, so we can keep track of this issue 
more easily, etc.

[gentoo-dev] Java and Mozilla (GCC 3 issue)

[Dafydd Walters]

I don't know if the Java plug-in issue for Mozilla has been addressed for
the upcoming 1.4 release, but I found a couple of interesting web pages
describing how to build the JDK from source using GCC 3, so that it will
work properly as a plug-in for Mozilla.

http://hints.linuxfromscratch.org/hints/javafromscratch.txt

http://archive.linuxfromscratch.org/mail-archives/lfs-dev/2002/08/0659.html

Is anyone currently working on an ebuild to do this?

I see that bug  10462 (Mozilla does not work with Java plugins) is marked as
resolved and a duplicate of bug 9016 (Ebuilds that help you to make a
working mozilla with java and gentoo-1.4), but the fix described in the
latter (compiling Mozilla with GCC 2.95.3) does not seem to be a good
long-term fix for this issue.

One thing.  The source code you download from Sun, is not the same source
code that they use for their binary release.  I am not sure of the
differences, but  I believe the affected areas are in Hotspot.  I would love
to see a benchmark done on this.

I didn't know that.  However, I think it might still be nice to have a
source-code ebuild of the JDK (this is very much in keeping with
Gentoo's philosophy, after all), even if it does not correspond to Sun's
"latest and greatest", as the Mozilla plug-in "breakage" is quite
annoying (for me anyway; I'm sure others agree).

Is anyone aware of work being done on such an ebuild?

I have done such an ebuild a few months ago, it is called sun-j2sdk and
is in portage. You have to download the source manually though due to
licence contraints.

With this ebuild you get a working java plugin for gcc-3.2 systems,
