Unable to convert : dcraw not found

[Kitof]

Hi,

I'm unable to convert .NEF to . JPG after a fresh docker install :

convertx  | stderr: sh: dcraw: not found
convertx  | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/1/DSC_0880.NEF" > "/tmp/gmSkKQBu".
convertx  | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o").
convertx  | 
convertx  | Failed to convert ./data/uploads/1/1/DSC_0880.NEF from nef to jpeg using graphicsmagick. error: Error: Command failed: gm convert "./data/uploads/1/1/DSC_0880.NEF" "./data/output/1/1/DSC_0880.jpg"
convertx  | sh: dcraw: not found
convertx  | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/1/DSC_0880.NEF" > "/tmp/gmSkKQBu".
convertx  | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o").

Any helps appreciated, thanks.

I thought graphicsmagick bundled dcraw but it seems like it don't. Maybe it is fixed in later versions of gm, could you test that?

dcraw should be compiled and added separately as add-on to GraphicsMagick according their official web page. Sombody already did something like that

I'm getting this same error now with the latest Dockerized version trying to convert a DNG Apple to jpg/png. convertx | stderr: sh: dcraw: not found convertx | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/4/IMG_9090.DNG" > "/tmp/gm8jjsMx". convertx | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o"). convertx | convertx | Failed to convert ./data/uploads/1/4/IMG_9090.DNG from dng to jpeg using graphicsmagick. error: Error: Command failed: gm convert ./data/uploads/1/4/IMG_9090.DNG ./data/output/1/4/IMG_9090.jpg convertx | sh: dcraw: not found convertx | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/4/IMG_9090.DNG" > "/tmp/gm8jjsMx". convertx | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o"). convertx | convertx | stderr: sh: dcraw: not found convertx | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/4/IMG_9091.DNG" > "/tmp/gmyc8c5V". convertx | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o"). convertx | convertx | Failed to convert ./data/uploads/1/4/IMG_9091.DNG from dng to jpeg using graphicsmagick. error: Error: Command failed: gm convert ./data/uploads/1/4/IMG_9091.DNG ./data/output/1/4/IMG_9091.jpg convertx | sh: dcraw: not found convertx | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/4/IMG_9091.DNG" > "/tmp/gmyc8c5V". convertx | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o").

oof i just tried to push a commit but this thing does not want to build on alpine linux! has anyone successfully done it? i can use apk add dcraw but then it throws up linker errors which lead to adding many many more packages and then it still doesn't install as expected for me. weird.

The problem as mentioned by @C4illin earlier is that the dcraw is not bundled in the GraphicsMagick, pull and compile it directly in the docker container to fix it.

apk add build-base wget https://www.dechifro.org/dcraw/dcraw.c gcc -o dcraw -O4 dcraw.c -lm -DNODEPS cp dcraw /usr/local/bin

OR use https://raw.githubusercontent.com/6by9/dcraw/refs/heads/master/dcraw.c

could add a RUN command to the image creation and sort this out 👍

@Kitof and others who want this: Could you test the latest :main image, anything missing?

EDIT: wait with this, it is a little broken now

[C4illin]

now it should be available on :main
