As per summary, check attached build log.

And _please_ try not to fix it in the wrong way:

So far a patch for qtjambi-4.5.0_p1 was added to qting-edge overlay.

It's not compatible with qtjambi-4.4.3, though...
Comment 3 Alistair Bush (RETIRED) gentoo-dev 2009-07-20 11:50:06 UTC
Ive had a look at this and have made some progress.  Now I have a completely new error :D

Will continue tomorrow....

Patch solving a part of the compilation errors.

I'm attaching what I managed to do yesterday about qtjambi-4.4.3. This solves the problem with const void* (the solution is taken from 4.5.0 code :P). But then again there is an issue about Qt Jambi generator generating wrong (too much of?) code:

     [make] ../cpp/com_trolltech_qt_core/qtjambishell_QRegExp.cpp: In function '_jobject* Java_com_trolltech_qt_core_QRegExp__1_1qt_1cap_1int__JI(JNIEnv*, _jobject*, jlong, jint)':                                                  
     [make] ../cpp/com_trolltech_qt_core/qtjambishell_QRegExp.cpp:120: error: redefinition of '_jobject* Java_com_trolltech_qt_core_QRegExp__1_1qt_1cap_1int__JI(JNIEnv*, _jobject*, jlong, jint)'                                    
     [make] ../cpp/com_trolltech_qt_core/qtjambishell_QRegExp.cpp:99: error: '_jobject* Java_com_trolltech_qt_core_QRegExp__1_1qt_1cap_1int__JI(JNIEnv*, _jobject*, jlong, jint)' previously defined here

When you take a look at cpp/com_trolltech_qt_core/qtjambishell_QRegExp.cpp, there really is a redefinition of '_jobject* Java_com_trolltech_qt_core_QRegExp__1_1qt_1cap_1int__JI(JNIEnv*, _jobject*, jlong, jint)', because the file contains this method 2 times, first commented as 'QRegExp::cap(int nth)' and second as 'QRegExp::cap(int nth) const'. I don't know if it's a Gentoo-related issue or not, anyway, qtjambi-4.5.0_p1 generates the first one method of these two.

Patch solving the compilation errors for qtjambi-4.4.3

By doing some fine tuning of typesystem*.xml files I managed to get qtjambi-4.4.3 compiling with gcc-4.4 and qt-4.5.2. I was basing on qtjambi-4.5.0_p1 code, but please someone review this patch as I'm not 100% sure that the manipulation of the Java stuff is done the proper way :)
Comment 6 Davide Pesavento gentoo-dev 2009-07-20 19:10:03 UTC
Wouldn't it be better to just bump qtjambi to 4.5.0_p1 (now in qting-edge) which already has a (very simple) patch?
Comment 7 Dominik Kapusta (RETIRED) gentoo-dev 2009-07-20 19:19:45 UTC
Seems a nice idea, since qt-*-4.5.1 is already marked stable, and people are going to have Qt 4.5.1 rather than 4.4.*. And I may be wrong, but I guess that I needed such a tricky patch for qtjambi-4.4.3 because it linked against Qt 4.5.2 libs (and not 4.4.*) on my system.

Moreover, I'm pretty sure that qtjambi-4.5.0_p1 patch doesn't break stuff ;) which I can't say about the 4.4.3 one.
Comment 8 Alistair Bush (RETIRED) gentoo-dev 2009-07-22 11:09:05 UTC
bumped to 4.5.0_p1
