[Digikam-users] KDCraw hates me!

[Paul Waldo]

Hi all, 

I am running Kubuntu Gutsy with the stock digikam installed. I have built and installed digikam 0.9.4-rc1 in /usr/local. I cannot edit raw images, as kdcraw is unable to decode the image. 

There seems to be two issues here: 

    1. kdcraw run from within digikam fails, saying it can't decode the image. When I try to run the command manually, it seems to work fine! 
    2. the new digikam is using the stock version in /usr/lib/libkdcraw3 , rather than the one in /usr/local/lib/libkdcraw3. This is not a big deal, as both are version 8.83. I'd certainly like to rectify this for when the versions differ! 

Here are my environment settings: 

paul at aphrodite /usr/local/src/graphics/digikam-0.9.4-rc1 
$ env|grep /usr/local 
LD_LIBRARY_PATH=/usr/local/lib: 
KDEDIR=/usr/local:/usr 
PATH=/usr/local/bin:/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/paul/bin 
MAN_PATH=/usr/local/man:/usr/local/man: 
PWD=/usr/local/src/graphics/digikam-0.9.4-rc1 
KDEDIRS=/usr/local:/usr 

Below is the (edited) output from running digikam then trying to edit a raw file.

So, just on a whim, I tried running the command manually, both the old and the new kdcraw: 

paul at aphrodite /usr/local/src/graphics/digikam-0.9.4-rc1 
$ /usr/lib/libkdcraw3/kdcraw -c -v -4 -H 4 -b 3.77 -w -q 3 -o 0 /media/camera/2008-05-25/photo2008-05-25_10-56-06-000023.crw > /dev/null

As you can see, both the old version and the new version decode the file just fine. Note that this happens only on Powershot G1 images. My Rebel raw images are decoded OK. Any ideas on why 

    1. kdcraw hates my G1 images? 
    2. dcraw is using the old kdcraw? 

Thanks in advance!
