If you're sure you only use standard python libs it's fairly easy.

make a recipe (name it how ever you like)

SCR_URI = "file://<your script>.py"

do_install() {
install -m 0755 <your script>.py ${bindir}/<your script>.py
}

RDEPENDS:${PN} += "python3-core"

in the image

IMAGE_INSTALL += "<your recipe name>"

---

if your script needs further libraries, reference them in the recipe with

RDEPENDS:${PN} += "python3-core dependency1 dependency2 dependency3..."

Then you call the result on your device with <your script>.py from any console

Maybe add a "#!/usr/bin/env python3" shebang as a first line to your script

Hello, 

Can anyone suggest how to make a python script executable on the yocto image? I 've been trying with the pyinstaller but didn't work, I made it executable on my laptop and transfer it to yocto image but didn't work also, 
Has any one tried it before? are there other alternatives? 

YP AB Intermittent failures meeting
===================================
Aug 26, 2021, 9 AM ET
https://windriver.zoom.us/j/3696693975

Attendees: Tony, Richard, Trevor, Randy, Alex, Saul, Sakib!


Summary:
========

It was a rough week for testing due to glibc-2.34 and rust
problems so we'll see if the next week let's us return to:
ptest results continue to improve but there's still room
for even more improvement.

The make/ninja load average limit is in but it's not clear
if it's effective yet and it breaks dunfell. Trevor investigating
(Aug 26!).

There's not much new this week, I've commented on a few existing
activities below and added "Aug 26" in most cases.


If anyone wants to help, we could use more eyes on the logs,
particularly the summary logs and understanding iostat #
when the dd test times out.



Plans for the week:
===================

Richard: biking and wait for QA results for M3.
Alex: SWAT plans. September email, training. libevent monotonic fix!
Sakib: hook more responsive load average in to latency test. (v3)
Trevor: patch to set PARALLEL_MAKE : -l 50
-> dunfell, gatesgarth, hardknott (Aug 5 - it's a priority)
Investigate dunfell which failed with this change.
- data on WR AB load average.
Saul: none
Randy: Gather more iostat data, graph it!

Meeting Notes:
==============

1. job server

- ninja could be patched with make's more responsive algorithm
next or is this good enough?

Aug 26:
Randy made some graphs that show that the -l NUM results
in the number of compile jobs oscillates *wildly* between 0 and 200
on a 192 core builder compiling chromium. What I did was:
$ bitbake -c cleansstate chromium-x11
$ bitbake -c configure chromium-x11
$ bitbake -c compile chromium-x11
and while that compile was running:
$ while [ ! -f /tmp/compiling-chromium-is-done ]; do \
cat /proc/loadavg >> procs-load.log ; sleep 0.5 ;
done
Results so far:
https://postimg.cc/gallery/3hjfYfG/f8f46c97
Next step is either:
a. collect data as above for an image build and see if the sub-optimal
ninja behaviour makes a difference
and/or
b. patch ninja with make's more responsive load avg
algorithm:
https://git.savannah.gnu.org/cgit/make.git/commit/?id=d8728efc8


- Richard suggested that we extract make's code for measuring the load
average to a separate binary and run it in the periodic io latency
test. Also can we translate it to python?
- Trevor is working on this and had some problems so next week.
(Aug 19 - Trevor is back from vaction so maybe next week.)

- Trevor to see if the load average change really did reduce load
on WR build systems. (Aug 19)

2. AB status

Trevor is learning about buildbot and working on a scheduling bug
(CentOS worker?)

bitbake layer setup tool should allow multiple backends:
eg: kas, a y-a-helper.

ptest cases are improving, we may be close to done!
Let's wait a week to see how things go.
(July29, Aug 5, Aug 19, we're not done...)

- lttng-tools ptest is failing. RP is working on it with upstream.
The timeout (done on Aug 5) increase hasn't helped.


3. Sakib's improvements to the logging are merged.

Sakib generated a summary of all high latency 'top' logs from
~July 23->July 29 by just running his summary script on the
merged raw top logs.

More analysis required....


Still relevant parts of
Previous Meeting Notes:
=======================


4. bitbake server timeout ( no change july 29, Aug 19)

"Timeout while waiting for a reply from the bitbake server (60s)"

5. io stalls (no update: July 29)

Richard said that it would make sense to write an ftrace utility
/ script to monitor io latency and we could install it with sudo
Ch^W mentioned ftrace on IRC.
Sakib and Randy will work on that but not for a week or two
or longer! (Aug 19).

Randy collected iostat data on 3 build server:
https://postimg.cc/gallery/8cN6LYB
We agreed that having -ty-2 be ~ 100 utilization for many hours
in a row is not acceptable and that a threshold of ~ 10 minutes
at 100% utilization may be a reasonable limt. I need to figure out
if I can get data on the fraction of IO done per IO clas since
we do use ionice to do clean-up and other activities.


../Randy

Please post the exact error that you're getting.

Sorry, I haven't posted the exact error because I thought it is quite specific to the recipe I'm building. My first question was also too vague, sorry for that. The problem is that it fails in building that package because of a missing file that should be populated by that dependency.

The error happens in the do_compile task:

| make[1]: *** No rule to make target 'm4_image.bin', needed by 'flash_linux_m40'.  Stop.                                                                                                                             
| make: *** [Makefile:23: flash_linux_m40] Error 2                                                                                                                                                                    
| WARNING: exit code 2 from a shell command.

So, the package expects that the file 'm4_image.bin' exists, and this file is generated by the dependency (it works well when building the yocto image, but not when building the SDK from scratch).

Thanks,
Alejandro

Hello,

We have a custom package recipe that has a build dependency with
another one (defined in yocto with the DEPENDS variable). If we build
an image that includes that package, bitbake will build the
dependency
before building the package, as expected. However, if we build the
SDK
associated to that image (with bitbake <image> -c populate_sdk), it
will fail in building that package because of a missing dependency.
Does anyone know what could be causing this behavior?

Can that recipe for dependency package actually be built for nativesdk?

Thanks,

Hi,

I'm trying to add a recipe for:
https://github.com/bootlin/libva-v4l2-request package. This library
heavily depends on actual kernel headers (see
PR.https://github.com/bootlin/libva-v4l2-request). I've bumped kernel
to 5.14-rc7 nad in recipe I'm trying to use what is suggested:

# This is how linux-libc-headers says to include custom uapi headers
CFLAGS_append += " -I ${STAGING_KERNEL_DIR}/include/uapi -I
${STAGING_KERNEL_DIR}/include "
do_configure[depends] += "virtual/kernel:do_shared_workdir"

Problem is that I see a lot of errors like:
kernel-source/include/linux/cache.h:6:10: fatal error: asm/cache.h: No
such file or directory
| 6 | #include <asm/cache.h>

or
recipe-sysroot/usr/include/bits/stdint-intn.h:27:19: note: previous
declaration of 'int64_t' was here
| 27 | typedef __int64_t int64_t;

I tried to compile this package manually on the host only difference
is that I used headers from 5.14 by make headers_install and
everything compiled fine. Any ideas on how to fix this issue?

Thanks and BR,

marek

2.30.2

Hi! 

I would like to implement an out-of-tree  ASoC Machine driver in my project. It #includes some in-tree header files such ../codecs/codecX.h. These are however not found when I try to build the recipe. I have followed the example project "hello-mod", but that doesn't require any in-tree header files, so it doesn't help in this case. 

What do I need to do in oder for Bitbake to find these headers ?
Thanks!

Hi Sergei,

Thanks for the advice, the latest ofono in oe-core master is 1.32, but
I am in branch Hardknott, so I copied ofono 1.32 from master to my
layer running Hardknott branch, but I could not build ofono 1.32 in
Hardknott:

ERROR: ParseError at
/build/oe-cor/../meta-solar/recipes-connectivity/ofono/ofono_1.32.bb:22:
unparsed line: 'SYSTEMD_SERVICE:${PN} = "ofono.service"'

I used ofono 1.30 and connman 1.37 in Zeus, both worked fine , but
both connman 1.39 and ofono 1.31 failed to work properly in oe-core
Hardknott branch, to narrow down if it is ofono issue or Yocto OE
build or other library issue, I was able to build ofono 1.30 for
Hardknott, I can confirm that ofono 1.30 failed just like the 1.31
stuck at the statement add_serial_device.

................
ofonod[2806]: ../ofono-1.30/plugins/udevng.c:add_serial_device()
Device is missing required OFONO_DRIVER property
ofonod[2806]: ../ofono-1.30/plugins/udevng.c:add_serial_device()
Device is missing required OFONO_DRIVER property
ofonod[2806]: ../ofono-1.30/plugins/udevng.c:add_serial_device()
Device is missing required OFONO_DRIVER property

If I run ofono 1.30 built from Zeus build, the ofonod would pass
missing OFONO_DRIVER property and kept it work:

......
ofonod[3712]: ../ofono-1.30/plugins/udevng.c:add_serial_device()
Device is missing required OFONO_DRIVER property

ofonod[3712]: ../ofono-1.30/plugins/udevng.c:create_modem() driver=ubloxqmi
ofonod[3712]: ../ofono-1.30/src/modem.c:ofono_modem_create() name:

/sys/devices/soc0/soc/2100000.aips-bus/2184200.usb/ci_hdrc.1/usb1/1-1
.....

So I don't think it is an oFono issue, but rather an OE Yocto build or
library issue, can anyone run oFono in oe-core Hardknott branch?

Thank you.

Kind regards,
