Hello. I have FreeBSD 4.9 in /etc/make.conf CFLAGS= -O -pipe COPTFLAGS= -O -pipe kde compiles like this cc -DHAVE_CONFIG_H -I. -I. -I../.. -I/usr/local/include -I/usr/X11R6/include -UQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -pthread -DQT_THREAD_SUPPORT -I/usr/local/include -I/usr/local/include -I/usr/X11R6/include -D_GETOPT_H -D_THREAD_SAFE -DNDEBUG -O2 -O -pipe -march=pentiumpro -c `test -f 'xs_colors.c' || echo './'`xs_colors.c source='xs_hsv.c' object='xs_hsv.o' libtool=no \ there line -O2 -O -pipe -march=pentiumpro for every compilation file so my CFLAGS override default O2 kde flags? do i need to recompile kde with O2 flag? Will KDE work faster? Regards Dmitry. ___________________________________________________ . Account management: https://mail.kde.org/mailman/listinfo/kde. Archives: http://lists.kde.org/.
