The moc you use is not for Qt 4.1.4 Michael
I suggest that the build mechanery should be changed to test for the correct moc version. Any M4 wizards around?
I had this trouble with GCC 4.3 and edited: gcc-4_3-build/i686-pc-linux-gnu/libjava/classpath/native/jni/gtk-peer/Makefile (generated) to change "moc" to "moc-qt4"
Results for 4.3.0 20070716 (experimental) testsuite on i686-pc-linux-gnu http://gcc.gnu.org/ml/gcc-testresults/2007-07/msg00721.html
This Bug still occurs with: "gcc version 4.4.0 20090111 (experimental) [trunk revision 143259]" 1. Don't use cached valued of 'moc' for 'moc-qt4'. 2. Check default install location even if NOT on the path at: # /usr/local/Trolltech/Qt-4.4.3/bin/moc -v Qt Meta Object Compiler version 59 (Qt 4.4.3)
This should be fixed by: http://git.savannah.gnu.org/cgit/classpath.git/commit/?id=c814d82e5a435f93150cd28b7cf0f9d600ff400d which stores the moc-qt4 check separately and uses it in preference.
