moc: too many input files

[thorsten at staerk.de]

Dear buildsystem,

I often get an unsermake error that I can work around. The error is:

kde-devel at scorpio:~/kdelibs4_snapshot/kdeui> unsermake
creating ../kdeui/kshortcutdialog_simple.moc
moc: Too many input files specified
Usage: moc [options] <header-file>
    -o<file>           Write output to file rather than stdout
    -I<dir>            Add dir to the include path for header files
    -E                 Preprocess only; do not generate meta object code
    -D<macro>[=<def>]  Define macro, with optional definition
    -U<macro>          Undefine macro
    -i                 Do not generate an #include statement
    -p<path>           Path prefix for included file
    -f[<file>]         Force #include, optional file name
    -nw                Do not display warnings
    -v                 Display version of moc
Error creating ../kdeui/kshortcutdialog_simple.moc. Exit status 1.


OK, so I look what unsermake wants to do:


kde-devel at scorpio:~/kdelibs4_snapshot/kdeui> unsermake -n | head
echo 'creating ../kdeui/kshortcutdialog_simple.moc'
/home/kde-devel/qt-unstable/bin/moc  -DQT_THREAD_SUPPORT -D_REENTRANT 
-I/home/kde-devel/kdelibs4_snapshot/kdefx
-I/home/kde-devel/kdelibs4_snapshot/interfaces
-I/home/kde-devel/kdelibs4_snapshot/dcop
-I/home/kde-devel/kdelibs4_snapshot/libltdl
-I/home/kde-devel/kdelibs4_snapshot/kdefx -I../kdecore
-I/home/kde-devel/kdelibs4_snapshot/kdecore

-I/home/kde-devel/kde-unstable/include 
/home/kde-devel/kdelibs4_snapshot/kdeui/kshortcutdialog_simple.h
../kdeui/kshortcutdialog_simple.h -o ../kdeui/kshortcutdialog_simple.moc
...


OK, so we see, unsermake tries to use two identical input files instead of
one:
/home/kde-devel/kdelibs4_snapshot/kdeui/kshortcutdialog_simple.h and
../kdeui/kshortcutdialog_simple.h
I now issue this command manually with only one input file:


kde-devel at scorpio:~/kdelibs4_snapshot/kdeui>
/home/kde-devel/qt-unstable/bin/moc  -DQT_THREAD_SUPPORT -D_REENTRANT 
-I/home/kde-devel/kdelibs4_snapshot/kdefx
-I/home/kde-devel/kdelibs4_snapshot/interfaces
-I/home/kde-devel/kdelibs4_snapshot/dcop
-I/home/kde-devel/kdelibs4_snapshot/libltdl
-I/home/kde-devel/kdelibs4_snapshot/kdefx -I../kdecore
-I/home/kde-devel/kdelibs4_snapshot/kdecore
-I/home/kde-devel/kdelibs4_snapshot/kdeui
-I/home/kde-devel/kdelibs4_snapshot/kio
-I/home/kde-devel/kdelibs4_snapshot/kio/kio
-I/home/kde-devel/kdelibs4_snapshot/kio/kfile
-I/home/kde-devel/kdelibs4_snapshot -I/home/kde-devel/qt-unstable/include
-I/home/kde-devel/qt-unstable/include/Qt
-I/home/kde-devel/qt-unstable/include/QtCore
-I/home/kde-devel/qt-unstable/include/QtGui
-I/home/kde-devel/qt-unstable/include/QtXml
-I/home/kde-devel/qt-unstable/include/Qt3Support -I/usr/X11R6/include
-I/home/kde-devel/kde-unstable/include 
/home/kde-devel/kdelibs4_snapshot/kdeui/kshortcutdialog_simple.h  -o
../kdeui/kshortcutdialog_simple.moc
kde-devel at scorpio:~/kdelibs4_snapshot/kdeui>

and everything is okay again. Can't we do anything against unsermake
trying to do a moc with two identical input files ?
