Hi,
I followed the wiki to rebuild the fedora 32 kernel from the fedora source tree (with the aim to enable a few configs and apply some patches - for now it is just trying to re-build the kernel).
I followed the instructions step by step but it seems that it is unable to find an include (during the fedpkg local step). Here are the steps I took and the output.
$ toolbox enter # I'm using silverblue
$ sudo dnf install fedpkg fedora-packager rpmdevtools ncurses-devel pesign grubby
...
Complete!
$ fedpkg clone -a kernel
Cloning into 'kernel'...
...
Resolving deltas: 100% (47534/47534), done.
$ cd kernel
$ sudo dnf builddep kernel.spec
...
Complete!
$ git checkout -b my_branch origin/f32
Branch 'my_branch' set up to track remote branch 'f32' from 'origin'.
Switched to a new branch 'my_branch'
$ sed -i 's/# define buildid .local/%define buildid .local/g' kernel.spec

I tried the same with export CPATH="/usr/include/:" (the location of /usr/include/elf.h) but I got the same error message.
