I want to build an upstream kernel with the Debian image's configuration. My system is normally i386 but I use the
-amd64 variant
so I want to build that one.
My workflow is like this: I build kernels in a i386 jessie chroot. I use the upstream tarballs, copy the config file of the relevant debian kernel variant and then "make olddefconfig && make deb-pkg ..."
The problem is:
1. I can build pae kernels just fine using the config file of Debian's -686-pae image. It builds the kernel and creates i386 deb packages.
2. When I try to build -amd64 kernel, using the config file of the
-amd64 variant of the i386 package
(the one I've linked above), make deb-pkg creates deb packages with the
amd64 architecture
(the resulting deb files end in _amd64.deb, contrary to the packages I've linked above).
3. Instead, if I build with ARCH=i386 make olddefconfig && ARCH=i386 make deb-pkg, using the same config file from the -amd64 variant of the i386 package, the resulting debs are _i386.deb files, but this time
they're really i386, not even PAE
.
I compared the .config file from the (2) and (3) after the kernels are compiled, and they're same.
So, what is the procedure to follow building the -amd64 kernels but in i386 deb files?
I tested it and the correct invocation is:
Code:
Select all
make deb-pkg ARCH=x86_64 KBUILD_DEBARCH=i386
It builds a 64 bit kernel, but packages it for i386 architecture.
