Subject: [PATCH] kbuild: rpm-pkg: add libelf-devel as alternative for
BuildRequires
Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due
to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b
("kbuild: add ability to make source rpm buildable using koji").
The relevant package name in openSUSE is libelf-devel.
Add it as an alternative package.
BTW, if it is impossible to solve the build requirement, the final
resort would be:
$ make RPMOPTS=--nodeps rpm-pkg
This passes --nodeps to the rpmbuild command so it will not verify
build dependencies. This is useful to test rpm builds on non-rpm
system. On Debian/Ubuntu, for example, you can install rpmbuild by
'apt-get install rpm'.
NOTE1:
Likewise, it is possible to bypass the build dependency check for
debian package builds:
$ make DPKG_FLAGS=-d deb-pkg
NOTE2:
The 'or' operator is supported since RPM 4.13. So, old distros such
as CentOS 7 will break. I suggest installing newer rpmbuild in such
cases.
