Hi Ali,

Seems an interesting board, the Udoo. PengPod has Cortex-A8 while Udoo
has Cortex-A9. But machine name is armv7l in both cases, meaning the
same compiler flags may be used. If you want I can send you a project
by private mail (don't want to clutter the list with this) which
builds some home-brew externals and some externals from Pd-extended on
RPi and PengPod amongst others. If it would build on Udoo too, we'd
know a bit more.

Hello,
Looks like the Udoo is the same as the PengPod.
Is the PengPod  something like:  http://pandaboard.org/

?


Here's what i get:

ubuntu@imx6-qsdl:~$ uname -s

Linux

ubuntu@imx6-qsdl:~$ uname -a

Linux imx6-qsdl 3.0.35 #1 SMP PREEMPT Mon Aug 19 07:11:31 PDT 2013 armv7l
armv7l armv7l GNU/Linux

Hello Ali,

A while ago I've compiled home-brew Pd externals on Raspberry Pi and
PengPod Linux tablet, and found that for each ARM processor type you
can identify them by their proper name as returned by command uname
-m. For RPi this is armv6l and for PengPod armv7l. So I could define
individual flags for those ARM types in the makefiles.

There is no general approach to this, as makefiles in various Pd
extended libs can be very different. In the template makefile which is
used for many libs, the operating system is tested first with uname
-s. If it is Linux, the processor type is found with uname -m and
stored in variable CPU, which seems to be used for target 'showsetup'
only, not for setting specific flags. Anyway, if you get "No rule to
make target xxx.pd_linux" when trying to build a lib with template
makefile, I wonder what you get from your Udoo board with command
uname -s?

hello all,
i'm working with a Udoo board (http://Udoo.org)
i've successfully compiled PureData 0.45 from miller's site;
i'm now trying to compile some of the externals in the pd svn, but i'm
getting the same error for all.

for instance, when trying to compile nusmuk-audio, i.e.

http://sourceforge.net/p/pure-data/svn/17203/tree/trunk/externals/nusmuk/nusmuk-audio/

i get the following

ubuntu@imx6-qsdl:~/pd-externals/nusmuk/nusmuk-audio$ make

make: * No rule to make target `bq~.pd_linux', needed by `all'.
Stop.

I have contacted the developer (cyrille henry) and he adjusted the
MakeFile
to account for building for ARM; but i get the same error.  I notice,
incidentally, that i get the same error ("No rule to make target
xxx.pd_linux") for all other externals that i tried from the repository.

does anyone have any thoughts on how to resolve this?


thanks,


ali
