Compiling toolchain

[Compizfox]

Hi,

I'm trying to compile ML for my 550D. I followed this guide: http://magiclantern.wikia.com/wiki/Build_instructions/Unified
But everytime I run summon-arm it stops with Error 2, though it doesn't show what the error is.

I don't know what to do. Could someone help me?

Thanks,

If you are running linux, then give up building and download a pre-built toolchain from https://launchpad.net/gcc-arm-embedded (specifically, download this: https://launchpad.net/gcc-arm-embedded/4.6/4.6-2012-q2-update/+download/gcc-arm-none-eabi-4_6-2012q2-20120614.tar.bz2 ). In makefile.inc say
  ARM_ABI=none-eabi
  ARM_PATH=<where_you_installed_toolchain>

It you're on Win, there's a pre-built toolchain there, too, but it's not enough to compile ML.

On Mac, I have no idea.

On Mac, I have no idea.

Summon-arm patched for ML like in the source code.

Yes I'm running Linux. Thank for the tip, I'll try the precompiled one! Maybe a good thing to put into that wiki article? Should save you a bunch of minutes compiling (and those errors, of course)

[Compizfox]

I installed the toolchain and modified the Makefile.inc like you said.

First I came across an error:

Code Select Expand

/bin/sh: line 2: readelf: command not found
make[1]: *** [autoexec] Error 1
But when I googled it, I found http://chdk.setepontos.com/index.php?topic=5971.msg74918#msg74918. It said to modify Makefile.inc at line 337 from readelf -l magiclantern | grep -C 2 MemSiz to $(ARM_BINPATH)/arm-none-eabi-readelf -l magiclantern | grep -C 2 MemSiz.
So I did that and when I build ML with make 550D it produces a autoexec.bin at ./platform/550D.109.

Is this really the only thing I need? My ML 2.2 installation has got a couple of other files like fonts.dat, retilin.lut and the folders doc and cropmks.
I tried to build with make zip but then I get this error:

Code Select Expand

debug.o: In function `run_test':
debug.c:(.text+0x26c): undefined reference to `dumpf'
collect2: ld returned 1 exit status
make[1]: *** [magiclantern] Error 1
make[1]: Leaving directory `/usr/src/magic-lantern/platform/60D.111'
make: *** [60D] Error 2

I can't find anything about that with Google.

When I place the autoexec.bin from ./platform/550D.109 at the root of my SD-card, and I boot my 550D, it shows nothing but a black screen.
Did I do something wrong?

[scrax]

So I did that and when I build ML with make 550D it produces a autoexec.bin at ./platform/550D.109.

try to comment out the line with dumpf in debug.c

[nanomad]

Btw, if you are on Mac or Windows (!) you can use the Yagarto toolchain just fine

[Compizfox]

try to comment out the line with dumpf in debug.c

Thanks, I found two lines in ./src/debug.c with dumpf and I commented them out both.
But now I get another error:

Looks like it's looking for the compiler at /bin/sh: /home/lars/arm-toolchain462/bin/arm-elf-gcc-4.6.2 although I set the right path in Makefile.inc. Do I have to set it somewhere else or something?

EDIT:
Ah I found it, the path at ./plugins/Makefile.top was wrong. Second attempt...

EDIT:
Found a second wrong path at ./platform/7D.123/Makefile. Corrected it, but still get the following errors:

Btw, if you are on Mac or Windows (!) you can use the Yagarto toolchain just fine

+1 for yagarto, makes compiling on mac super easy. No waiting for summon-arm, everything is pre-built. Just extract the files somewhere and you're set.

[Compizfox]

Yes!

make zip still doesn't work (I can't get to compile the docs or something). But when I tried make all, I just got one easy error (I needed to repair the readelf path (yes, again) in symtblgen.rb. After that I got a working autoexec.bin in ./platform/all/.
Copied that to my SD-card and now my 550D was actually booting. I just needed to place fonts.dat from ./src and cropmks to ML/DATA and now it's working.

But still haven't any clue on the documentation...

make 550D

Why are you making ml for all the other cameras.

[rambler]

I can't get to compile the docs

Compiling docs needs a bunch of other stuff installed (latex & pandoc + dependencies, to name the obvious).

make 550D

Why are you making ml for all the other cameras.

I tried making for only the 550D, but with that autoexec.bin on my SD-card my camera won't boot.

Compiling docs needs a bunch of other stuff installed (latex & pandoc + dependencies, to name the obvious).

I installed these:

sudo apt-get install python-matplotlib python-matplotlib-data python-matplotlib-doc python-matplotlib-dbg texlive-luatex python-docutils texlive-latex-base texlive-latex-recommended texlive-fonts-extra dvi2ps texlive-math-extra pandoc texlive-latex-extra ruby-full
Or isn't that enough? That is what the wiki said.

[nierymek]

Compizfox: I had the same problem in Ubuntu 12.04 - you have to find rst2latex (in my case: /usr/share/docutils/scripts/python2/rst2latex)
and symlink it to eg. /usr/sbin/rst2latex.py

[Compizfox]

Thank you very much! I'm gonna try it now!

And indeed, I'm running Linux Mint KDE Lisa.

EDIT:
Symlinked /usr/bin/rst2latex to /usr/sbin/rst2latex.py. Docs compiled without problems now. Thank you!

I installed 2 different toolchains: Sourcery and Launhpad.net  arm toolchains .. but the 2 of them make the same copiling error:

Not sure what's the cause, but when I get that I run make clean, then make, and works. Probably something in the linker script.

wow that's strange!  This was a completely new checkout of the code.. unchanged but Makefile.inc to point to my toolchain ... but your make clean and then remake did the trick! 

[mkrjf]

can you provide info on compiling on mac (and yagarto link does not help)
