Re: [PATCH 11/19] kbuild: rpm-pkg: use a dummy string for _arch when undefined

[chenxiang (M)]

Hi,

I build the latest kernel (6.6-rc1) for arm64 platform on x86 server 
(with cross complile), and the complile command is as following:

export 
PATH=$PATH:/opt/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin/
export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-

make -j64 Image (ok)

make binrpm-pkg -j64 (failed)

But when complile binrpm-pkg, it is failed and the error info is as 
following:

rpmbuild -bb kernel.spec --define='_topdir 
/home/chenxiang/kernel/mainline/linux-next/rpmbuild' --target 
aarch64-linux --build-in-place --noprep --define='_smp_mflags %{nil}' 
$(rpm -q rpm >/dev/null 2>&1 || echo --nodeps) --without devel
rpmbuild: --build-in-place: unknown option
make[2]: *** [scripts/Makefile.package:92: binrpm-pkg] Error 1
make[1]: *** [/home/chenxiang/kernel/mainline/linux-next/Makefile:1538: 
binrpm-pkg] Error 2
make: *** [Makefile:234: __sub-make] Error 2

But it is ok with v6.5-rc7, so i bisect the kernel code and find the 
patch (kbuild: rpm-pkg: use a dummy string for _arch when undefined):

Do you have any idea about this issue?


Thanks
