Odd FTBFS in kdepim 3.5.13

Hello, I'm trying to rebuild kdepim 3.5.13 on redhat-based distributions, and on some variants, I get an FTBFS, not on other. It used to work before, so I'm disappointed. The FTBFS is: (taken from RHEL 5 x86) ---------- [ 1%] Building CXX object ktnef/gui/CMakeFiles/ktnef.dir/attachpropertydialogbase.cpp.o cd /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui && /usr/lib/ccache/c++ -D_FILE_OFFSET_BITS=64 -DHAVE_CONFIG_H -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=generic -fasynchronous-unwind-tables -DQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION -DQT_THREAD_SUPPORT -D_REENTRANT -include tqt.h -I/home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui -I/home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/ktnef -I/home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/libkdepim -I/opt/trinity/include -I/usr/lib/qt-3.3/include -I/opt/trinity/include/tqt -o CMakeFiles/ktnef.dir/attachpropertydialogbase.cpp.o -c /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp: In constructor 'AttachPropertyDialogBase::AttachPropertyDialogBase(QWidget*, const char*, bool, uint)': /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:101: error: invalid use of undefined type 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.h:21: error: forward declaration of 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:102: error: invalid use of undefined type 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.h:21: error: forward declaration of 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:103: error: invalid use of undefined type 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.h:21: error: forward declaration of 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:104: error: invalid use of undefined type 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.h:21: error: forward declaration of 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:105: error: invalid use of undefined type 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.h:21: error: forward declaration of 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:105: error: incomplete type 'KListView' used in nested name specifier /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:107: error: no matching function for call to 'QGridLayout::addMultiCellWidget(KListView*&, int, int, int, int)' /usr/lib/qt-3.3/include/qlayout.h:336: note: candidates are: void QGridLayout::addMultiCellWidget(QWidget*, int, int, int, int, int) /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp: In member function 'virtual void AttachPropertyDialogBase::languageChange()': /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:149: error: invalid use of undefined type 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.h:21: error: forward declaration of 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.cpp:150: error: invalid use of undefined type 'struct KListView' /home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build/ktnef/gui/attachpropertydialogbase.h:21: error: forward declaration of 'struct KListView' make[2]: *** [ktnef/gui/CMakeFiles/ktnef.dir/attachpropertydialogbase.cpp.o] Error 1 make[2]: Leaving directory `/home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build' make[1]: *** [ktnef/gui/CMakeFiles/ktnef.dir/all] Error 2 make[1]: Leaving directory `/home/albator/rpmbuild/BUILD/BUILD.el5.i386/kdepim/build' make: *** [all] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.53807 (%build) ---------- When looking in "attachpropertydialogbase.cpp", I see that it lacks the line: "#include <klistview.h> . That's why it fails. In a working build environment, the same file contains the include, and it compiles correctly. It looks like the "attachpropertydialogbase.cpp" and "attachpropertydialogbase.h" are both autogenerated with "uic". I tried running "uic" manually in both build environment, and I confirm that in one case, I get the "#include <klistview.h>", and in another case, i do not get it, and then it FTBFS. What could cause a different behaviour in the uic utility ? (Note: both build environment have same QT, kdelibs, etc ... versions) Thanks François
