While doing a make of linux kernel for 4.15.10 on arch Linux which is running 4.12.8-1-ARCH.
Getting below packages are missing, when trying to install there is no packages by that name.


root@osboxes linux-stable]# make -j4
Makefile:938: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop.

could not find any of 3 packages.

From arch repo found and Installed "pacman -Syy libelf". however when i query list packages dont see the libelf.
and make fails.

PS: Arch Linux is running in Virtual Box.

Try looking under elfutils. I have that on Crux and it includes libelf.

Could you suggest way to update all the packages and install development packages/tools which will enable for kernel compilation?


My Arch Linux is running 4.12.8-1-ARCH kernel , which is latest (month). Please note this is virtual Box image.


On this was building 4.15.10,

1 picked the current kernel config from /proc/config.gz
2. $[linux_src/] cp config .config
3. $[linux_src/] make defconfig
4. sudo pacman -Syy gnome-common yelp-tools intltool cvs docbook-xsl js185 ragel gperf ruby xorg-util-macros xf86-input-wacom base-devel openssh gtk-doc python2-dbus glib2-docs cmake

5. if i run: make defconfig

[root@osboxes linux-stable]# make defconfig
HOSTCC scripts/basic/fixdep
/usr/lib/gcc/x86_64-pc-linux-gnu/7.3.1/cc1: error while loading shared libraries: libmpfr.so.6: cannot open shared object file: No such file or directory
make[1]: *** [scripts/Makefile.host:90: scripts/basic/fixdep] Error 1
make: *** [Makefile:461: scripts_basic] Error 2

[root@osboxes linux-stable]# find / -iname "libmpfr.so.*"
/usr/lib/libmpfr.so.4.1.5
/usr/lib/libmpfr.so.4

It seems need to update packages...

I'm not sure exactly which instructions you're using, but I would run a 'make clean'. Then, pic a config file from the configs directory in the kernel sources. Debian-based systems have had trouble just grabbing the current config from /proc or /boot.

Install libmpfr6. If it isn't in the repos, then your version is too old to compile the kernel you want. After you clean up the sources, edit Makefile and change the revision to something unique, preceded by a '-'. Then run 'make oldconfig'. Then configure the kernel with make xconfig, or gconfig, or menuconfig, or plain old config if you want hours of mindless tedium. On Debian-based systems I usually build using 'make -jX deb-pkg'.

Are you using the sources from the repos?
