Hallo,

I am a Fedora-Linux user and I tried to get cr2hdr to work.
First I tried to build it from the source using the method outlined here for Ubuntu:
https://bitbucket.org/hudson/magic-lantern/commits/50345b4d561151e4707c04e2b874e1f909bef6d9
But I gave up on the part of using dpkg to prepare the gcc compiler.

Luckily I came across the bitbucket archive of rufustfirefly
https://bitbucket.org/rufustfirefly/magic-lantern/downloads
where I can download a statically linked binary. Cool. 32 bit, I use 64, but it still works.

However when I call it with one of my files, it gives me:
[bastian@simpsus 20140712]$ ~/temp/cr2hdr-static.linux.x86.2014-06-19-f9a29c7c0685 IMG_0123.CR2
cr2hdr: a post processing tool for Dual ISO images

cr2hdr: print a message when overwriting the output file

Active options:
--amaze-edge    : use a temporary demosaic step (AMaZE) followed by edge-directed interpolation (default)
--cs2x2         : apply 2x2 chroma smoothing in noisy and aliased areas (default)

Input file      : IMG_0123.CR2
Camera          : Canon EOS M
Full size       : 0 x 0
Active area     : 0 x 0
Error: pgm width


which I cannot make any use of. Has somebody a hint for me to either
use cr2hdr on linux/fedora or
how to get rid of this error?

Thanks,
Bastian

Thanks for the hint.
I am new to the M and I have bought some cheap M42 lenses off Ebay with an M42 to EF adapter and an EF to EF-M adapter but I keep getting errors
"lens communication faulty, clean contacts" or
"lens firmware update failed"

What is that lens/adapter combination you are sportin on the M?
