[yocto] [meta-anaconda][PATCH] packagegroup-installer-x11-anaconda: use libsdl2 instead of libsdl

[Yi Zhao]

The libsdl had been moved out of oe-core because it is obsolete. Switch
to libsdl2.

Re: [yocto] quilt-native-0.64-r0 do_install: oe_runmake failed

[Khem Raj]

error return code 126 means  Command invoked cannot execute so my
guess is the script is not marked executable. so may be try something
like

do_install_prepend() {
  chmod +x config/install-sh
}

might be you need to install gstreamer1.0-omx on target.

[yocto] Yocto Project Newcomer & Unassigned Bugs - Help Needed

[sjolley.yp.pm]

All,

 

The triage team is starting to try and collect up and classify bugs which a
newcomer to the project would be able to work on in a way which means people
can find them. They're being listed on the triage page under the appropriate
heading:

 

https://wiki.yoctoproject.org/wiki/Bug_Triage#Newcomer_Bugs

 

The idea is these bugs should be straight forward for a person to help work
on who doesn't have deep experience with the project.  If anyone can help,
please take ownership of the bug and send patches!  If anyone needs
help/advice there are people on irc who can likely do so, or some of the
more experienced contributors will likely be happy to help too.

 

Also, the triage team meets weekly and does its best to handle the bugs
reported into the Bugzilla. The number of people attending that meeting has
fallen, as have the number of people available to help fix bugs. One of the
things we hear users report is they don't know how to help. We (the triage
team) are therefore going to start reporting out the currently 297
unassigned or newcomer bugs.

 

We're hoping people may be able to spare some time now and again to help out
with these.  Bugs are split into two types, "true bugs" where things don't
work as they should and "enhancements" which are features we'd want to add
to the system.  There are also roughly four different "priority" classes
right now, "2.8", "2.9', "2.99" and "Future", the more pressing/urgent
issues being in "2.8" and then "2.9".

 

Please review this link and if a bug is something you would be able to help
with either take ownership of the bug, or send me (sjolley.yp...@gmail.com)
an e-mail with the bug number you would like and I will assign it to you
(please make sure you have a Bugzilla account).  The list is at:
https://wiki.yoctoproject.org/wiki/Bug_Triage#Unassigned_or_Newcomer_Bugs

 

Thanks,

 

Stephen K. Jolley

Re: [yocto] Segmentation fault | bitbake machine-image.bb | core dumped

[Randy MacLeod]

On 8/19/19 12:33 AM, jaymin.da...@vivaldi.net wrote:

Hi Randy,

Thanks for info.
But, as you can see from previous logs, I was getting core dumped issue 
at the time of bitbake (while building the image).

How can I find the cause of this type of core dumped?


Hi Jaymin,

While I'd like to help you with each step, I'm usually not going
to do that (unless you become a Wind River customer. :) )


To save us and anyone who might be reading this thread some time,
it looks like the program you are having trouble with is from a
meta-android layer or elsewhere. On ubuntu it's packaged in
android-sdk-ext4-utils:
   $ make_ext4fs

   Command 'make_ext4fs' not found, but can be installed with:

   sudo apt install android-sdk-ext4-utils  # version 8.1.0+r23-2, or
   sudo apt install android-tools-fsutils   # version 5.1.1.r38-1.1

Please read the rest of this email and let us know if you added
that layer into your conf/bblayers.conf file for reference.


Good luck,
../Randy


So, I wanted to confirm that bitbake wasn't preventing the
core file from being generated, so I used a private machine running
ubuntu-19.04 and replaced the gcc executable with my own program
as shown below. Since you already have an error happening,
you don't have to do this.


Here's my simple program in /tmp/hw.c

#include 
#include 

void  do_segv() {
  int *psplat = 0;
  int x = -1;
  x = *psplat;
}


int main(int c, char *v[]) {
  printf("Hello world\n");
  do_segv();

  exit(0);
}

Compile it:
gcc -g -o /tmp/hw /tmp/hw.c

Now set the kernel's core_pattern as explained in:
http://www.linuxhowtos.org/Tips%20and%20Tricks/coredump.htm

$ sudo su -
First save the old pattern:
# cat /proc/sys/kernel/core_pattern  > /root/old-core-pattern
# echo "core.%e.%p" > /proc/sys/kernel/core_pattern
# exit

Under your own user id:
$ ulimit -c unlimited

$ Test that we can generate a core dump outside of bitbake:
$ /tmp/hw
Hello world
Segmentation fault (core dumped)
$ file core.hw.20982
core.hw.20982: ELF 64-bit LSB core file, x86-64, version 1 (SYSV), 
SVR4-style, from '/tmp/hw', real uid: ..., execfn: '/tmp/hw', platform: 
'x86_64'


$ gdb /tmp/hw core.hw*
...

...
Reading symbols from /tmp/hw...
[New LWP 20982]
Core was generated by `/tmp/hw'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x55af3c18617a in do_segv () at /tmp/hw.c:12
12x = *psplat;
(gdb) bt
#0  0x55af3c18617a in do_segv () at /tmp/hw.c:12
#1  0x55af3c1861a7 in main (c=1, v=0x7ffc801bfc38) at /tmp/hw.c:20
(gdb)



So, now I want to use this as a test to confirm that I can generate
a core file when running bitbake to simulate your problem. In your
case, everything is setup so that you should be able to start debugging 
'make_ext4fs' but running bitbake, getting a core file, then running:

$ gdb make_ext4fs /path/to/core.pattern


I know that the OS doesn't depend on having a functioning compiler all
the time so I'm going to *save*, then over-write the compiler. You call
'gcc' to compile a program but it's actually a series of links on my
Ubuntu distro:

$ ls -l /usr/bin/gcc
lrwxrwxrwx 1 root root 5 Apr  4 00:23 /usr/bin/gcc -> gcc-8
$ ls -l /usr/bin/gcc-8
lrwxrwxrwx 1 root root 22 Apr  6 11:04 /usr/bin/gcc-8 -> 
x86_64-linux-gnu-gcc-8

$ ls -l /usr/bin/x86_64-linux-gnu-gcc-8
-rwxr-xr-x 1 root root 19336 Aug 19 14:53 /usr/bin/x86_64-linux-gnu-gcc-8


Copy the simple test program over the compiler executable BUT ...

SAVE IT FIRST!!!


# WARNING: only do this on a system that other people are not using:
$ sudo mv /usr/bin/x86_64-linux-gnu-gcc-8 \
  /usr/bin/x86_64-linux-gnu-gcc-8.orig
$ sudo cp /tmp/hw /usr/bin/x86_64-linux-gnu-gcc-8

Now, I know that m4-native is one of the first programs that use gcc
so I can run:
$ bitbake -c configure m4-native

...

Re: [yocto] [OE-core] Yocto Project Summit at ELCE Call for Particpation

[Paul Barker]

Hey folks,

I'm looking to submit a talk and I'm a little confused on when to register for 
the YP summit. Should I register now to get the discounted rate or should I 
wait until the list of accepted speakers is announced? Unlike for the main 
conference, it looks like the registration price goes up before the list of 
accepted speakers is released. It's also not very clear whether accepted 
speakers will be given complimentary registration.

Thanks,
Paul

Are you using a clean thud setup or updating the kernel to the current
HEAD? You shouldn't hit this issue following the versions use in the
thud branch of meta-raspberrypi. Long story short, the build system
doesn't take advantage of the precompiled dtb files available in the
Raspberry Pi firmware repository. It maintains a list of dtb as a
variable and compiles them while compiling the kernel. I suspect that
you have a bbappend which updates the kernel to current HEAD (includes a
dtb rename backport).

Hello all,

Can anyone help on where are the headers located in crossbuilds? Any
help appreciated.
The recipe:

[yocto] [meta-mingw] QEMU on thud mingw SDK is broken

[Sinan Kaya]

I noticed last week that qemu packaged into mingw sdk is broken while
the qemu in linux sdk works fine.

Qemu crashes very early while launching the kernel boot.
This used to work fine on sumo.

Does anybody see this problem too?

[yocto] Yocto Project Summit at ELCE Call for Particpation

[Philip Balister]

At the past few OopenEmbedded developer meetings, people have been
asking for more developer and user focused events like a miniconf.
Partly based on this feedback, there is a two day event sponsored by the
Yocto Project that provides a chance for people to talk about the Yocto
Project and OpenEmbedded. The CFP is a bit buried on the page and I like
to get it more exposure, so here the direct link:

https://events.linuxfoundation.org/wp-content/uploads/2019/08/Yocto-Project-Summit-2019-CFP-1.pdf

We'd like to see new faces talking. We know there are a lot of good
stories out there, that will help lots of people become better users and
developers.

The link to the event is here:

It is right here:

There is a link that lets you modify an existing registration by adding
'extras' to it, and yocto summit is one such. You need a registration code
for the original conference that came with the confirmation email.

[yocto] [meta-raspberrypi] Issues building bcm2835_bootfiles in Thud

[Phillip Marks]

We are building Thud for a raspberry-pi0+wifi and we've noticed that the
recipe bcm2835_bootfiles under meta-raspberrypi/recipes-bsp/bootfiles is
not pulling in the proprietary *.dtb modules from the firmware repository.
This is causing linux-raspberrypi to fail as it tries to build those
modules and fails on "no target found for bcm2708-rpi-0-w.dtb". How does
bcm2835_bootfiles pull in the Broadcom firmware modules and where in build
does it store them? We don't see them in tmp/work.

[yocto] [PATCH] In Yocto 2.7 powertop package is broken.

[Kaz Kylheku]

Hi all,

Via a .bbappend file in my own layers, I added the following patch to
build powertop, which is enabled when tools-profile is added to
EXTRA_IMAGE_FEATURES.

* recipes-profiling/powertop/files/posix-path-max-not-defined.patch:
Patch for build issue. The C++ code needs to including  which
defines the POSIX PATH_MAX preprocessor symbol.

I like the idea however this is going to break the autobuilders as they
already use full paths in the variable.

I've merged some of the other patches but this one will need a little
further thought so we don't break the existing install.

The existing code also allows for different path locations on
individual workers (e.g. different username) which this would break.

Cheers,

Richard

[yocto] Recipe svn-fetcher and scmdata

[Teemu K]

Hi,

I have some recipes that fetch sources directly from svn. I'd like to
keep the .svn to make it easier to commit changes. I checked that
those are by default removed and that there is scmdata - option if
those wanted to be kept.

I set the following src_uri:

SRC_URI = 
"svn://my.svn.server/svn/sw_components/program/;module=trunk;protocol=http;scmdata=keep"

Yet the .svn - data is removed from the sources under build -
directory. It is in under download directory though so I'm wondering
if I got this right in the first place?

I tried with devtool modify and it seems I ended up having .git -
directory there although sources are in svn. Maybe it's systems
'subtle' way of telling me to switch to git? ;)

But should the scmdata=keep option work like I'm thinking it should
and/or what I'm doing wrong?
