All versions of Linux-2.6 I install qt and all other stuff in /usr; and do not set QTDIR, as it is not needed. Can /usr be added to the scripts/kconfig/Makefile? I attach a patch. The last two variables of: @set -e; for d in $$QTDIR /usr/share/qt* /usr/lib/qt*; do \ if [ -f $$d/include/qconfig.h ]; then DIR=$$d; break; fi; \ seem pointless as it is looking for a header file. The patch just adds /usr to the end; but I suggest that the line could be @set -e; for d in $$QTDIR /usr; do \ Chris Lingard
