Description Ville Skyttä 2006-05-30 21:27:25 UTC

qt4's debuginfo package is useless:

$ rpm -qlp
http://fedoraproject.org/extras/development/i386/debug/qt4-debuginfo-4.1.3-5.fc6.i386.rpm
(contains no files)

More info: http://fedoraproject.org/wiki/Packaging/Debuginfo

Comment 1 Rex Dieter 2006-06-08 13:02:02 UTC

Looks like qmake is to blame, it uses (by default):
QMAKE_STRIP             = strip
QMAKE_STRIPFLAGS_LIB    += --strip-unneeded

So, at least for the initial qt4 (rpm) build, I'll have to override these
(default) values.

Comment 2 Rex Dieter 2006-06-08 20:38:05 UTC

This will also affect all(most?) apps/libraries built against qt4 using qmake. 
They will also end up with useless -debuginfo rpms.  For example, see
texmaker-debuginfo-1.3 currently in Extras.

2 options:
(1) Disable QT_STRIP (unconditionally).  patch mkspecs/%{platform}/qmake.conf:
QMAKE_STRIP = /bin/true

(2) Create a new QMAKESPEC, named, say, debuginfo(*), cloning mkspecs/default to
mkspecs/debuginfo, and then modify mkspecs/debuginfo/qmake.conf to include instead:
QMAKE_STRIP = /bin/true
Default behavior would stay the same (ie, include the ability to strip, which
matches upstream default behavior), while allowing a different QMAKESPEC for
packagers who want/need (useful) -debuginfo rpms.  This would require packagers
to use:
qmake4 -spec debuginfo
and/or set
export QMAKESPEC=debuginfo
before running qmake4.

(*) debuginfo is the first name I came up with.  Can use any new/unique name here.

Comment 3 Rex Dieter 2006-06-08 20:40:37 UTC

It appears (un)setting
QMAKE_STRIP = 
works too.

Comment 4 Michael Möllney 2006-06-22 22:12:15 UTC

But where to find the qt4 debug libraries.

using in the qt .pro file:
CONFIG += debug

makes the linker complain about:
/usr/bin/ld: cannot find -lQtGui_debug

I can't find the package containing:
libQtGui_debug.so.4.1.3
and analog files.
Shouldn't this be also in this debuginfo???

or is the qt4-devel the right rpm?

Comment 5 Rex Dieter 2006-06-22 22:15:10 UTC

qt4 as-is isn't built with debug libraries (only ./configure --release).  If you
want/need that, please file another report.

Reclosing...
