Hi all, after a fresh install and full update of FC6, I'm unsuccesfull in installing CISCO VPN Client vpnclient-linux-x86_64-4.8.00.0490-k9.tar.gz in my AMD64 box: make -C /lib/modules/2.6.18-1.2798.fc6/build SUBDIRS=/root/vpnclient modules make[1]: Entering directory `/usr/src/kernels/2.6.18-1.2798.fc6-x86_64' CC [M] /root/vpnclient/linuxcniapi.o /root/vpnclient/linuxcniapi.c:12:26: error: linux/config.h: No such file or directory In file included from /root/vpnclient/Cniapi.h:15, from /root/vpnclient/linuxcniapi.c:27: /root/vpnclient/GenDefs.h:110:2: warning: #warning 64 bit yum list 'kernel*' return: ..... Installed Packages kernel.x86_64 2.6.18-1.2798.fc6 installed kernel-devel.x86_64 2.6.18-1.2798.fc6 installed kernel-headers.x86_64 2.6.18-1.2798.fc6 installed .... So, what I've missed?
