I'm trying to install NISTNet network simulator but when I "make" the program, the following error appears:
make: Entering directory '/home/sw/nistnet-3.0a/kernel'
make -C /lib/modules/2.6.20-1.2948.fc6/build M=/home/sw/nistnet-3.0a/kernel V=1
make: Entering an unknown directory
make: *** /lib/modules/2.6.20-1.2948.fc6/build: No such file or directory. Stop.
I have kernel-devel and kernel-headers packages installed but the build directory does not exists.
The directory /lib/modules/2.6.20-1.2948.fc6/build is a link that points to ../../../usr/src/kernels/2.6.20-1.2948.fc6-i586. Again, build folder is not there.
Thanks in advance
