change in kernel directories

[AbhijitG]

Hi,
I have upgraded from ubuntu 10.10 to 11.04.
& had uame -r > 2.6.38-15-generic-pae
Now the problem is when i want to build kernel modules it doesnt have build directory in location /lib/modules/2.6.38-15-generic-pae/
I can not compile the modules without those and with the previous kernel files :(
Plz Can anybody tell me what is happening?

/lib/modules/ is only cleaned when a kernel is purged. So you might have the kernel(s) subfolder(s) actually installed. Update the system and reinstall the missing kernel, then /lib/modules/ will have it.
