[Dqt-users] DQT CVS fails to build (no matching function call to log4cxx::Logger::getLogger)

[Stuart L. <red...@ge...>]

Hi,
	I'm trying to install DancingQT, with the view of trialling its
suitability for a scottish country dancing group[1] I'm connected with,
as a possible replacement for their aging variable-speed tape deck.
With the price of laptops comming down, Linux becomming more user
friendly, and the high price of commercially available variable speed CD
players ... a software-based solution like DancingQT is a very
favourable option.

	At the moment, the test machine is my main desktop (a dual PIII 1GHz,
1GB RAM running Gentoo Linux/x86 2005.1), the target will likely be a
Celeron 366MHz laptop running the same OS.

	On compiling DancingQt, I get a number of error messages from gcc,
which abort the compilation...

	Here[2] you'll find the ebuild script I'm using to compile DQT from
CVS.  I get the same results doing it by hand, and via the build script.

	The library version (along with the features enabled) I'm using are as
follows:
> [ebuild   R   ] x11-libs/qt-3.3.4-r8  +cups +doc +gif +ipv6 +mysql +opengl +sqlite
> [ebuild   R   ] media-sound/jack-audio-connection-kit-0.99.0-r1  +alsa +doc 
> [ebuild   R   ] media-sound/alsaplayer-0.99.76  +alsa +doc +esd +flac +gtk +jack +mikmod +nls +opengl +vorbis
> [ebuild   R   ] dev-db/sqlite-3.2.1-r3  +doc
> [ebuild   R   ] media-libs/taglib-1.4
> [ebuild   R   ] dev-libs/log4cxx-0.9.7-r2  +doc +unicode

	I've looked at the source code, and although it looks correct, there's
something about it that gcc doesn't like.  I've tried both gcc 3.3.6 and
gcc 3.4.4, with and without security-hardening patches.

	Google doesn't turn up much either... so I'm at a loss as to what's
causing this problem.  Ultimately, I'd like to release this package into
the tree so it can gain more exposure, as there are a number of dancing
groups looking for such a solution.
