[uClinux-dev] [PATCH] elf2flt: rename Blackfin relocs

2009-06-04 Thread Mike Frysinger

We renamed all the Blackfin relocs in the toolchain to match other ports
(all caps and a R_BFIN_ prefix), so update elf2flt accordingly.

[uClinux-dev] Zeroconf with uClinux?

2009-06-04 Thread Krause Mathias (ST-CO/ENG4.3)

Hi all,

I am named to implement something zeroconf on our embedded linux system 
(uClinux on coldfire, 32bit). Currently I've no idea, where to start. I think, 
what I need is mDNS and IP local.
Is there anybody out there who made a bonjour-compatible device by running 
uClinux? Any hints where to start?

I already tried to cross-compile the apple bonjour, but as I am a bit 
inexpirienced in uClinux I ran into a lot of problems.
I also tried to cross-compile avahi (with most of the features disabled) but I 
also can't get it to compile.

Now, I read in a mailing list, that libavahi is included into uClinux-dist. 
Unfortunately I cannot find anything.
Any hints, starting points or help would be very appreciated.

Thanks,
Mathias

Re: [uClinux-dev] Zeroconf with uClinux?

2009-06-04 Thread Steve Bennett

We run the apple mdnsresponder on a few devices to advertise a web  
interface.


# ps | grep mDNS
  276 root   612 SmDNSResponderPosix -n myhost -t _http._tcp - 
p 80


Nothing special was required to get it going.

Cheers,
Steve

RE: [uClinux-dev] Zeroconf with uClinux?

2009-06-04 Thread Krause Mathias (ST-CO/ENG4.3)

Hi,

Thanks for that answer. In the meantime I got just exatly the same 
mDNSResponder running.
Now I want to use local IP so that 2 devices can reach each other just by 
connecting them to a switch and without setting up an ip adress before that. I 
think I need zeroconf therefore?

Regards,
Mathias

[uClinux-dev] for information : tutorial about uCllinux installation (MCF5329 Fire Engine module - Ubuntu 9.04)

2009-06-04 Thread Valentin Rouquette

Hello,

I made a tutorial (in French ... :-/ ) about the uCllinux installation
(with LTIB). It is an installation on the Freescale MCF5329 Fire
Engine module, and the development computer is under Ubuntu 9.04. It's
a summary of my experience.
I will translate this tutorial soon (I hope it will be done before this summer).

http://doc.ubuntu-fr.org/tutoriel/freescale_coldfire

Best Regards.

Val

Re: [uClinux-dev] building gcc 3.4.4

2009-06-04 Thread Jeff Bacon

Ok, so I've figured out that it has to point to my specific headers to
compile, and I've made it through almost all of the steps EXCEPT for
one of the last ones, step 8(repeated here):


8. gcc-3.4.4 (c++, etc)

   tar xvzf gcc-3.4.4.tar.gz
   cd gcc-3.4.4

   cp $(ATTACHED t-linux file) gcc/config/arm/
   vi gcc/config/arm/t-linux
  - remove all -Dinhibit_libc occruances
   vi gcc/config/arm/linux-elf.h
 -- remove line that defines LIBGCC_SPEC
   perl -pi -e 's/int namelen/unsigned int namelen/'
libjava/java/net/natInetAddressPosix.cc

   mkdir arm-linux
   cd arm-linux
   ../configure --target=arm-linux --disable-shared \
--prefix=/usr/local --with-headers=linux-2.4.x/include \
--with-gnu-as --with-gnu-ld --enable-multilib
   make
   make install


The compilation makes it almost all the way through until it hits the
section where it's working on libstdc++-v3, where it dies with this
error:

snip
checking for float.h... (cached) yes
checking for stdint.h... (cached) yes
checking for main in -lm... configure: error: Link tests are not
allowed after GCC_NO_EXECUTABLES.
make: *** [configure-target-libstdc++-v3] Error 1
[r...@localhost arm-linux]#


I'm so close I can taste it, can anyone (Greg??) help me out here? I'm
following Greg's instructions EXACTLY, so if anyone else has then they
would have had to have seen this error I would think. I'm building it
on the recommended Fedora Core 3 machine by the way...

 Well, if I look at the build directions for the gcc 4.2.1 toolchain on
 the snapgear website they essentially have the same steps but are
 using  --with-headers=linux-2.6.x/include instead or 2.4.x. I'm just
 wondering if I need to make the same modification for the 3.4.4 build
 steps, or if that was just something specific to gcc 4.2.1).
