error: implicit declarations while compiling (xenomai3.1+ubuntu20.04)

error: implicit declarations while compiling (xenomai3.1+ubuntu20.04)

[João Costa]

Hello,

I am having some problems with a fresh install of Xenomai 3.1 and I was
hoping that someone could help me out solving those
 or by sharing some installation instructions for dummies.

*Test bench configuration:*
-Ubuntu server 20.04.2 running kernel 5.4.0-73-generic
-Xenomai version 3.1
-Kernel downloaded for patch/installation: linux-5.4.77.tar.gz (since I
could not find an exact match with ipipe patch and the kernel already
running)
-ipipe-core-5.4.77-x86-2.patch

*I am following this instructions:*
- https://www.programmersought.com/article/14375437246/
- had the need to install/change some packages " gcc libncurses-dev flex
bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev
libiberty-dev build-essential kernel-package"
- assumed that where is written:
$makeolddefconfig
it should be
$make oldconfig

*I am getting the following errors:*
*after running* " CONCURRENCY_LEVEL=8 make-kpkg  --rootcmd fakeroot
--initrd  --revision=1.0.0 kernel_image kernel_headers "
*#1*

 make[1]: *** [Makefile:1729: kernel] Error 2


*Notes:*
- I am not sure it my answers when executing the $make oldconfig were the
correct ones and/or can be related to these problems
- Also, the checks/unchecks in the kernel menu ($menuconfig) are not
exactly like the ones on those instructions since there are items that do
not appear or are enabled/embedded by default and cannot be unselected


Thanks

Strange. There was either a problem with patching the kernel (you can
cross-check by downloading a prepatched one from [1]), or you found a
.config that exposes a build error (then please share it).

[João Costa]

Thanks for your feedback.

I had no report of errors in the CLI while patching the kernel.
In attach you may find the .config file I am using.

I see that by default [1] goes to the ipipe-x86-4.19.y-cip
If I change the branch/tag to ipipe-core-5.4.77-x86-2 [2] will I by getting
the prepatched one for the version I was previously trying to use?

Thanks

Thanks, will give that a try.

Turn off CONFIG_HYPERV - neither needed nor supported (but the failure
mode is indeed unfortunate).

In general, as you are building a full-featured distro config, you will
likely get much more than you need. And have to wait for that much
longer. I can recommend "make localmodconfig" as alternative.

I guess it was enabled or because I could not find it in previously in the
"GUI" of  *menuconfig *or because is was one of those options that was
selected by default and could not be disabled.

I edited the file *.config* and disabled it as suggested.
Still I was getting this error:

So I followed your other suggestion of using "*make localmodconfig*"
instead and everything worked.

Just to be more precise, everything seemed to be going well until some
other errors shown up.
I have been fighting with these since then and I wasn't able to finish the
installation.
I will open a new and more generic thread.
