Ok, so you've installed Fedora 7 from the livecd but your wifi doesn't work.
So now you haven't got an internet connection and you want to compile a driver like ndiswrapper, unfortunately the build environment is missing
(With an internet connection you could just run yum groupinstall "Development Tools" and yum install kernel-devel)
You have to copy the following rpms from
http://download.fedora.redhat.com/pu...386/os/Fedora/
to a cd or usb stick (Total size is ~13Mb) and install using rpm -Uhv as follows
rpm -Uhv
kernel-devel-2.6.21-1.3194.fc7.i686.rpm
rpm -Uhv
kernel-headers-2.6.21-1.3194.fc7.i386.rpm gcc-4.1.2-12.i386.rpm glibc-devel-2.6-3.i386.rpm glibc-headers-2.6-3.i386.rpm libgomp-4.1.2-12.i386.rpm
The total size of these rpms is only ~13Mb, so god knows why these aren't included on the install cd
btw, ndiswrapper-1.45 compiles fine on the Fedora 7 install kernel
