Cannot build: Qt 4.8.1, Linux, error in qdrawhelper_sse2.cpp

[ChrisW67]

Hi All,
Perhaps someone can see the obvious problem with my attempt to build Qt 4.8.1 (or 4.8.0) on Linux using GCC.

@
$ make confclean
$ ./configure --prefix=/mnt/data/qt/qt-4.8.1 -plugin-sql-sqlite -opensource
--- 8< -- snip --
Qt is now configured for building. Just run 'gmake'.
Once everything is built, you must run 'gmake install'.
Qt will be installed into /mnt/data/qt/qt-4.8.1

To reconfigure, run 'gmake confclean' and 'configure'.
$ make

You could try hacking it by using the configure option -no-sse2

Hard to say what's going wrong, you've got a type 'Operator' that has not been defined, as to why, that may be a little tricky finding why.

Im out of topic, but yeah, another gentoo user here XD

Using -no-sse2 gets the process to a different failure point that seems related to ssse3. Adding -no-ssse3 gets me to more errors implying there might be some undesirable crossover with the system-wide Qt install (4.7.4).

I also found https://bugreports.qt-project.org/browse/QTBUG-14443 with an almost identical symptom caused by some private headers being installed system wide. Gentoo does this:
@
private-headers : Install Qt declarative private headers required by Qt-creator
QmlDesigner and QmlInspector plugins
@

painting/qdrawhelper_sse2.cpp does this:
@
include <private/qdrawhelper_x86_p.h>
@

so it could be picking up the unrelated
@
/usr/include/qt4/QtGui/private/qdrawhelper_x86_p.h
@

from the existing 4.7.4 install.

I'll keep chipping away at this and also look at how this is avoided in the Gentoo supplied builds for Qt.
