FuzzyOCR error on processing gif sample file
Downloaded and installed the latest FuzzyOCR 2.1c
Ran the tests and the jpg and png ones worked fine, but for the gif sample
I received:
spamassassin -t <ocr-gif.eml
giftopnm: error reading magic number
(null): EOF / read error reading magic number
Broken pipe
I have all the required files in place, any ideas? Other than that the
plugin looks good so far. Thanks.

You are probably missing more dependencies, like libpnm.
The symbols missing here are in the pnm library :)

Ok,
I installed libjpeg-devel, libpng-devel, and libtiff-devel, then I DL
and compiled netpbm-10.34 from source. it all went well, and now I
have all 3 of those convertor executables on my system. i then ran
some tests on your sample mails.
the gif sample works great. - exactly like in your README file.
the png sample gives me this error:
/usr/local/netpbm/bin/pngtopnm: symbol lookup error: /usr/local/
netpbm/bin/pngtopnm: undefined symbol: pnm_allocrow
ERROR pnm.c L213: read
and the jpeg sample gives me this error:
jpegtopnm: WRITING PPM FILE
/usr/local/netpbm/bin/jpegtopnm: symbol lookup error: /usr/local/
netpbm/bin/jpegtopnm: undefined symbol: pnm_allocrow
ERROR pnm.c L213: read
any ideas?
Thanks,
Devin

Re: FuzzyOCR install issues

Well,
I finally got everything working after realizing that there is a
RHEL4 package called netpbm-progs. So, i deleted everything i
installed from source, and installed all of the rpms instead. No
more errors. oddly enough, I only find 2 spam words in the sample
jpeg mail, as opposed to 4 in your README file.
Question:
there is the "focr_autodisable_score" parameter to skip FuzzyOcr if
there are already enough points. The problem is that FuzzyOcr runs
very early in the chain, and hence this feature is unusable. How can
I tell SA to run FuzzyOcr later or last?
Thanks,
Devin
FuzzyOCR install issues

Chris,
I am in the process of installing and testing FuzzyOcr, but i am
having some issues with netpbm.
I installed netpbm via yum and have version netpbm-10.25-2.EL4.2
installed now. the problem
is that giftopnm, jpegtopnm, and pngtopnm are nowhere to be found on
the system.
any suggestions? I'm on RHEL 4.1
Thanks,
Devin

FYI, I figured this problem out. I installed netpbm to /usr/local/netpbm/
and gocr was not able to find all the files easily. I reinstalled netpbm
to just /usr/local, recompiled gocr, and it works for the gifs now without
a problem. :)

Thanks. I removed the RHEL rpm for netpbm, installed 10.26 from source
(10.34 did not like RHEL 3 OS it seems) but still have issues with the gif
file. If anyone has a working system for RHEL 3 (centOS 3) and the new OCR
plugin, please post how you got it working. Thanks, and thanks for a great
plugin.

Your netpbm seems very old, I am using 10.34. This could be the cause,
try the newest version, though I can't guarrantee that this is the
cause. If that doesn't work, try saving the gif image from the
ocr-gif.eml sample and run the commands manually over the file to see
which step fails.

Hrm, I just ran the same command on the same file and it all worked fine.
Can you please tell me the versions of your toolchain? (giflib,
netpbm, gocr)
