Re: LyX on Mac: Error converting EPS to loadable format

Tue, 18 Sep 2007 02:57:49 -0700 

Hello,
the problem seemed to be an incompatibility of the ImageMagick and Ghostscript versions that are shipped with MacTeX-2007 (I used 20070520). 

\ImageMagick 6.3.3 03/06/07 Q16 http://www.imagemagick.org
GPL Ghostscript 8.57 (2007-05-11)



LyX calls convertDefault.py, which calls ImageMagick's convert, which 
calls gs, with a parameter '-sDEVICE=pam' which my ghostscript does not 
support.


The following posting
http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=8353

suggest to change this parameter to -sDEVICE=bmpsep8. This did not work 
very well for my images.
This is what I did and seems to work (I am not sure of any side effects 
though this might imply):


Edit the file
/usr/local/lib/ImageMagick-6.3.3/config/delegates.xml
and replace the occurence of "-sDEVICE=pam" by "-sDEVICE=ppm".

Regards,
Konrad

Gerard,

thanks for your investigations!
I tried what you suggested but it still does not work.


My ImageMagick (convert) is I assume the one that is by default 
installed by the MacTeX package. It lives in the default locations 
/usr/local/bin and /usr/local/lib.


Nevertheless I tried to set the variables you suggested:


dhcp-50-221:~ khofbaue$ cat .MacOSX/environment.plist <?xml 
version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" 
"http://www.apple.com/DTDs/PropertyList-1.0.dtd";>

<plist version="1.0">
<dict>
        <key>DYLD_LIBRARY_PATH</key>
        <string>/usr/local/lib</string>
        <key>MAGICK_HOME</key>
        <string>/usr/local</string>
</dict>
</plist>


And I also reverted the security patch you mentioned:

dhcp-50-221:~ khofbaue$ ls /var/db/.AllowDYLDEnvironmentVariables

-rw-r--r--   1 root  wheel  0 Sep 18 10:27 
/var/db/.AllowDYLDEnvironmentVariables



I also rebooted and reconfigured LyX after these changes. I also 
(independently) tried to set the variables in LyX's info.plist.


However, LyX still does not display eps figures.

Any further ideas?

Thanks,
Konrad

Konrad,


I had the same problem recently as well.  I traced it  to my new 
installation of ImageMagick.



I had downloaded the latest version of ImageMagick onto my Mac (binary 
release from http://www.imagemagick.org/script/index.php) and 
installed it according to the instructions on the website.  Unlike my 
earlier installation, which placed the binary files in /usr/local/bin 
and library files in /usr/local/lib, this version put them in 
/usr/local/ImageMagick-6.3.5/bin and /usr/local/ImageMagick-6.3.5/lib 
.  The installation instructions say to define the environmental 
variables MAGICK_HOME=/usr/local/ImageMagick-6.3.5 and 
DYLD_LIBRARY_PATH=$MAGICK_HOME/lib.  This works fine when running LyX 
from a Terminal window.  However clicking on the LyX icon directly 
fails to provide these environmental variables to ImageMagick.



At first, searching the web, I found instructions to define these 
environmental variables through the RCEnvironment preference pane 
(freeware, http://www.rubicode.com/Software/RCEnvironment/).  However, 
I found that RCEnvironment only sets the MAGICK_HOME environment, but 
fails to set DYLD_LIBRARY_PATH.



After much frustration, I found that the problem can be traced to a 
recent (May 07) security update in Mac OS X 10.4.9 
(http://docs.info.apple.com/article.html?artnum=305509).  The 
workaround, as indicated on Apple's website, is either to modify the 
Info.plist file in the LyX.app folder (which didn't work for me, 
perhaps I am missing something) or restore the pre-update permission 
to set DYLD_LIBRARY_PATH (which worked, but presumably defeats the 
security update).  After implementing the suggested change (and using 
RCEnvironment to set MAGICK_HOME and DYLD_LIBRARY_PATH, and including 
/usr/local/ImageMagick-6.3.5/bin in the  LyX path), I got ImageMagick 
to work again.

Hello,


I am sure it is something on my side (as nobody else complained about 
this so far), but I cannot figure out where the problem is.



I fairly recently made a new install on an Intel-based Apple using a 
standard install of MacTeX-20070520.dmg, and I also updated to LyX 
1.5.1.



However, EPS files do not show up in LyX anymore (Error converting to 
loadable format). They are fine in the Latex output.



Removing the LyX-1.5 directory in ~/Library/Application Support (so 
that a new configuration is created) does not change anything.



Below the console output, the convert-version, and the (longish) 
debug output from "lyx -dbg graphics"


Basically, LyX uses convertDefault.py which complains about:
> Unknown device: pam
> Unrecoverable error: undefined in .uninstallpagedevice
> Operand stack:
>     defaultdevice

Any ideas what this could mean?

Thanks,

The console.log says:
