It seems that powernow cool and quiet is not compiled since when I modprobe powernow_k8 says fatal module not found... So I got no cool and quiet... I tried to configure nad then compile the kernel make xconfig did not work and returned : /usr/bin/ld: cannot find -lqt collect2: ld returned 1 exit status make[1]: *** [scripts/kconfig/qconf] Error 1 make: *** [xconfig] Error 2 make menuconfig worked but then after saving the configuration I did make and give this error-- scripts/kconfig/confdata.c:88: warning: pointer targets in passing argument 1 of ‘conf_expand_value’ differ in signedness /usr/lib64/qt-3.3/bin/moc -i scripts/kconfig/qconf.h -o scripts/kconfig/qconf.moc HOSTCXX scripts/kconfig/qconf.o HOSTLD scripts/kconfig/qconf /usr/bin/ld: cannot find -lqt collect2: ld returned 1 exit status make[1]: *** [scripts/kconfig/qconf] Error 1 make: *** [xconfig] Error 2 [root@localhost linux]# make CHK include/linux/version.h make[1]: `arch/x86_64/kernel/asm-offsets.s' is up to date.
