problem to compile fedora kernel: BTF/pahole

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hi,

while trying to recompiling  fedora 5.12.17 kernel, I got a final error:

scripts/link-vmlinux.sh: Line 214: 273523 Killed LLVM_OBJCOPY="${OBJCOPY}" ${PAHOLE} -J ${1}

"dwarves" is installed, so this should not happen.

The config file is taken from /boot/ and adjusted via "make menuconfig" to use GZIP compression instead of libstd. Besides this, no other changes
are done.

# make bzImage
.. message that pahole is missing ..
# dnf -y install dwarves

Any ideas why this is happening?
