Hello all

I got this error and dont know what to do with that !

make[1]: *** No rule to make target 'host-python', needed by
'/home/user/cleta_buildroot/output/build/libevdev-1.8.0/.stamp_configured'.
Stop.
make: *** [Makefile:84: _all] Error 2
make: Leaving directory '/home/user/cleta_buildroot/buildroot'
user at LinuxDev:~/cleta_buildroot$


I already compiled with success bet I add some packages and got this.
I try to remove my change but got this error again... strange
Could I have a guidance to find from where problem come ?

(I compile the 2020.02.8 buildroot version for a specific imx6 board with
buildroot toolchain.)

[manu f]

ok, I remove libevdev in Target package =>libraries=>Other and its copile
without error!

(But I dont know if I realy need this lib... )

Well why it no compile with libdevdev ?
@ Thomas Petazzoni I saw you already got problem and make patch for
host-python interpreter...is there something to see with ?

host-python is definitely part of Buildroot 2020.02, so I'm not sure
how you can get this error. We would need more details, such as the
complete .config that reproduces the issue.

[Buildroot] No rule to make target 'host-python !!

[manu f]

Thanks peter.
What's mean Buildroot 2020.02.8-dirty?

About python37, yes I add this custom package but like you see I didn't
select it.
this config is without livdevdev and it compile right. but if I select it I
had th error I gave (do you think it could be a problem if I not set
libdevdev, I realy not sure I need it, sorry I didn't completly setupp this
buildroot jus modify some aspect and I am far to master all).

But its is strange that I have BR2_PACKAGE_PYTHON not set.
I will look later (I am not on my linux computer), I think I even havent
pithon item in menu-config...
Is this mean I have a problem with python dependencies ? I will check the
dependencies logic.

Peter, Its very strange that at your side you could compile with libdevdev
set and not me. Do you have an idea wher I could search?

Many thanks for helping.

Regards.

Emmanuel

[Buildroot] No rule to make target 'host-python !!

Hello Emmanuel,

This indicates normally a buildroot git repository at version
2020.02.8 (tag/branch) with local changes ('dirty')...

But the line '+# BR2_PACKAGE_PYTHON is not set' indicates that
there is no python package any longer with your build setup
(and so no host-python available needed by libevdev)...

Hard to judge without knowledge of your br-external but I would suspect
it contains a package/python directory with a python.mk file without
an '$(eval $(host-autotools-package))' line (or something like
that) and a Config.in file with BR2_PACKAGE_PYTHON_37 instead of
BR2_PACKAGE_PYTHON?

If so try to move .../br-exteranl/package/python to .../br-exteranl/package/python-37

Regards,
Peter

[Buildroot] No rule to make target 'host-python !!

[manu f]

You are right Peter!
You will find my python pakage joined.
Like I told you I am noob in kernel compil, so sure I made bad thing, but I
am here to learn.

So if I well understood even if I didnt select the package in menu config,
config.in and .mk file interferes with the build..
I use some other config.in and .mk file as model to build these file for my
package, so I make a mistake, if you could look them ?

Regards

(I remove the tar file in files directory cause it is to heavy to send, but
it's just python37 archive)

Besides the point I did not understand why you try to install some python37
binaries (or source?)....all vars in python37/python37.mk should be
named PYTHON37_... (instead of PYTHON_...) and the one in python37/Config.in
should be named BR2_PYTHON37...

Why not just enable the buildroot python3 package (will be python-3.8.6
when using buildroot-2020.02.8)?

Peter

[Buildroot] No rule to make target 'host-python !!

[manu f]

I will use the buildroot python package Peter.
In fact the app that I must deploy on the Kernel use the version 3.7, I
know it must work also with the version 3.8 but it was for me an exercise
to learn how to add a package! (not good result but I learn a lot with your
help)

Now I understand better how the .mk I made work with the build process.

Again thanks a lot for your help.

[Buildroot] No rule to make target 'host-python !!

Please stop using your custom BR2_EXTERNAL for the moment, and use plain
Buildroot, and verify there if this works.

If it does, then the problem is in your BR2_EXTERNAL tree. We cannot
debug problems that are caused by your custom BR2_EXTERNAL, in which
you're doing things that are very tricky and/or apparently unnecessary.

[Buildroot] No rule to make target 'host-python !! [SOLVED]

[manu f]

Hello,

Nothing very tricky in my BR2_EXTERNAL, unnecessary certainly !
I am in learning  curve so I think unnecessary things is inherent and
necessary :-)

But, well, I clone again from scratch my buildroot directory and no more
error !
it is the mystery of computing. ;-)
Thanks for your help, i learn a lot.

Regards
