Bug 333391 – Qt 4.6.3 is built without STL support

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Keith Rusler 2010-08-19 08:22:50 UTC]

Qt 4.6.3 doesn't build with STL which I need for my project.

Reproducible: Always

[Comment 1 Markos Chandras (RETIRED) 2010-08-19 22:16:50 UTC]

I assume we can add a use flag for it. Objections? Patches are always welcome

[Comment 2 Davide Pesavento (RETIRED) 2010-08-19 22:39:55 UTC]

WTF? We already pass -stl to the configure script...

[Comment 3 Keith Rusler 2010-08-20 00:46:04 UTC]

Well when I try use QString::fromStdString() etc like STL features in C++ it says they are not defined.

[Comment 4 Davide Pesavento (RETIRED) 2010-08-20 01:59:59 UTC]

I can't reproduce. Try re-emerging qt-core please.

[Comment 5 Keith Rusler 2010-08-20 03:35:56 UTC]

I just recompiled qt-core and can reproduce it again. I don't understand what is going on.

Attach /usr/share/qt4/mkspecs/gentoo/qconfig.pri please.

This shows that stl support is enabled.
So either you're doing something wrong or it's a gcc-4.5 issue.

[Comment 10 Keith Rusler 2010-08-21 15:27:15 UTC]

It might be a GCC-4.5.x bug, because I don't understand how I'm doing anything wrong. I've done it like it says to use that method in the documentation.

[Comment 11 Davide Pesavento (RETIRED) 2010-08-21 15:47:01 UTC]

I don't use gcc-4.5 myself, so I'm unable to debug this issue further. You can help by attaching a full build.log of x11-libs/qt-core.

[Comment 12 Bartosz Brachaczek 2010-09-02 19:15:25 UTC]

FWIW, I have world compiled with GCC 4.5.1 and my Qt 4.6.3 installation has proper STL support. My qconfig.pri differs from Keith's only in that I have a release build, not debug, and I have x86, not x86_64.

[Comment 13 Davide Pesavento (RETIRED) 2010-09-02 20:41:58 UTC]

Keith, attach your build.log for qt-core please.

[Comment 15 Keith Rusler 2010-09-02 23:56:26 UTC]

I experienced it also in Qt-4.7.0-rc1, I posted the build log

[Comment 16 Theo Chatzimichos (RETIRED) 2010-09-03 00:05:43 UTC]

build.log attached, reopening

[Comment 17 Keith Rusler 2010-09-03 00:29:35 UTC]

I fixed the issue. It seems that it was disabled in my KDE4 project using CMake. I had to use remove_definitions(-DQT_NO_STL) for it to work when building my CMake project with KDE4.
