Hello,
I am trying to build the linux kernel version 4.19.94 with xenomai 3.1 and the ipipe patch version 4.19.94-cip18-x86-10 on a debian 9 system.
I did not change anything in the kernel config except for disabling Hyper-V.
This works fine for the 64 bit kernel, but if I try to build a 32 bit kernel I get an error:
+ make -j 4
Makefile:590: include/config/auto.conf: No such file or directory

This output is from a 32 bit system, I get the same error if I try to build on a 64 bit system with "make ARCH=i386".
I have also checked the kernel config HAVE_IPIPE_SUPPORT via "make menuconfig", it says:
Symbol: HAVE_IPIPE_SUPPORT [=n]
x Type : bool
x Defined at kernel/ipipe/Kconfig:2
x Depends on: GENERIC_CLOCKEVENTS [=y]
x Selected by [n]:
x - X86 [=y] && X86_64 [=n]
Does this mean I can only build a 64 bit kernel with version 4.19.94 as there is no ipipe support for 32 bit or am I misinterpreting the HAVE_IPIPE_SUPPORT warning?
What else could be the issue?
Best regards
Jona

We've stopped supporting i386 configurations for the kernel. Even
vanilla i386 receives minimal testing, for many years now. Everyone is
at least on a 64-bit kernel if not also userland, possibly with compat
support for 32-bit applications. In fact, the latter is what we are also
using in one product.
