The new 4.92 installed nicely on this laptop... I am trying to get wireless networking going. I installed XEN. my kernel is 2.6.18-1.2747.el5xen I downloaded ipw3945-linux-1.2.0 This told me do download ieee80211-1.2.16 So when I try to compile ieee80211 it tells me find: /lib/modules/2.6.18-1.2747.el5xen/build/: No such file or directory egrep: /lib/modules/2.6.18-1.2747.el5xen/build//.config: No such file or directory egrep: /lib/modules/2.6.18-1.2747.el5xen/build//include/linux/autoconf.h: No such file or directory find: /lib/modules/2.6.18-1.2747.el5xen/build/: No such file or directory make: *** /lib/modules/2.6.18-1.2747.el5xen/build: No such file or directory. Stop. make: *** [modules] Error 2 the build directory is a symbolic link to /usr/src/kernels.... This directory is missing. What yum command do I execute to get it? THanks, Jerry
