FFMPEG support on ptxdist 2013.03.0

Hi All,

I would like to enable the FFMPEG on BSP. I checked ptxdist 2013.03.0 ffmpeg.in rule file it is stated that
this package belongs to application section. When I checked the application section on menuconfig, it is
not showing up the ffmpeg there. I tried to copy the ffmpeg.in and ffmpeg.make to BSP rule but still it wont
show up in application section on menuconfig.

any idea how to bring in this ffmpeg package to the BSP without upgrading the ptxdist 2013.03.0?

Thank you in advance.

enabling BSP as full development environment

Hello Experts,

Is it possible we can enable the configuration of  BSP into a full development environment (enabling gcc
and linker)? Where you can do ./configure, make and install.

Hi All Expert,

For the past few weeks, I never encountered depletion of entropy until yesterday where I could not able to
access my cortex A8 development board through wireless because of not enough entropy.

Searching for possible solution, I encountered rng-tool and haveged tool that possible to increase
entropy. I tried to find the rng-tool package from ptxdist menu but I could not find it. Somebody has idea
where I could enable it in the ptxdist menu?

Thank you!

iptables-1.4.8 required mdsum

Hello All,

Downloaded the latest iptables.in and iptables.make from oselas git repository. I enabled the iptables in ptxdist menuconfig under networking.
When I build it, it encounter error:md5sum for 'iptables' ... missing. How do I add that missing md4sum? I could not find it in the ptxdist menu.

Any helps are appreciated.

Best regards,

Could not download package

I'm trying to build OSELAS.BSP-Pengutronix-Mini2440, but it stops trying to download libusb-1.0.18.tar.bz2 from sourceforge.net. It also tried to download the file from pengutronix.de and also failed. The file does appear to be at sourceforge but not in the same place that ptxdist is looking for it:
Am I missing something?

Thanks, Doug

ptxdist: error: ptxd_make_xpkg_init: please define <PKG>_VERSION

OK, so I solved the problem of the undefined symbols. Had to do a distclean to remove all references to the older toolchain I had been using. Now it gets to:
target: glibc.targetinstall
And emits the subject error message. Of course there's no hint as to where <PKG>_VERSION should be defined. Here's the final message from make:
make: *** [/home/doug/ptxdist/projects/OSELAS.BSP-Pengutronix-Mini2440/platform-mini2440/state/glibc.targetinstall] Error 1
TIA, Doug

Latest mini2440BSP bash pidof problems

Upgraded a system that has been working nicely with the previous BSP and 3.7
and having a few problems.

My main PHP script starts with:



and the error I get when I invoke:

./data.php   (from the directory where this script is located) is

./data.php line 3: ?php: No such file or directory

I can work around this problem by calling:

php5 data.php

The issue that I have not been able to work-around is, that in another
script I ensure that data.php is killed before trying to start it again.

So, in an initialise script I have:


kill `pidof data.php`

and the error I get is:

kill: usage: [-s sigspec | -n signum | -sigspec] pid | jobspec ...
or kill -l [sigspec]

The usage does not correspond to the usage options listed in the Busybox
docs for kill, so I am confused.

I have Googled and tried many other kill examples to no avail.

I have tried php, bash, awk from the previous working system to no avail
either.  I also tried disabling Busybox ash as initially I was getting ash
warnings when running the bash script, which also confused me. I also read
that pidof might not operate correctly on running scripts.

Should I try maintaining a list of PIDS and then refer to that list when I
want to kill my data.php?

Something has changed, any suggestions appreciated.

OK, so I tracked down the header files to 
sysroot-arm-v4t-linux-gnueabi/usr/include. sys/socket.h includes 
bits/socket.h, which in turn includes bits/socket_type.h, which does in 
fact declare SOCK_NONBLOCK and SOCK_CLOEXEC. So what am I missing here?
