convert: Negative or zero image size

[rukka74]

Hi,

I have built ImageMagick 6.2.6 on a cross-compile environment (scratchbox) for an armv5b target. If I run convert like shown below from within scratchbox, which is using the remote shell to actually execute the binary on the target device everything works fine.
/volume1/opt/bin/convert -quality 75 -size 200x200 -geometry 200x200 /volume1/public/test/cmyk.jpg /volume1/public/test/convert/cmyk.jpg
(PS: I know that this command line is deprecated, but Gallery2 is still using it like that - and it works, so that shouldn't cause the problem).

If I then copy everything to the target device and run the same command, I get the following error:
convert: Negative or zero image size `/volume1/public/test/cmyk.jpg'.

Configure command was as follows:
--prefix=/opt --disable-installed --without-perl --with-magick-plus-plus=no


As you can see from below, all the required libs are found on the target.
./ld-linux.so.2 --list /volume1/opt/bin/convert
libMagick.so.10 => /volume1/opt/lib/libMagick.so.10 (0x40001000)
libWand.so.10 => /volume1/opt/lib/libWand.so.10 (0x4026a000)
libjpeg.so.62 => /volume1/opt/lib/libjpeg.so.62 (0x40304000)
libpng12.so.0 => /volume1/opt/lib/libpng12.so.0 (0x40329000)
libpthread.so.0 => /lib/libpthread.so.0 (0x4035d000)
libdl.so.2 => /lib/libdl.so.2 (0x403b5000)
libm.so.6 => /lib/libm.so.6 (0x403c0000)
libc.so.6 => /lib/libc.so.6 (0x4046c000)
/lib/ld-linux.so.2 => ./ld-linux.so.2 (0x2aaaa000)

Here you'll find the strace output from the successful execution in scratchbox and from the failed execution on the target

Maybe someone can give a hint?

Try the command without the -geometry option. The error you are getting is from the image resize method. Does that work? If so, try -resize 200x200 instead of -geometry. Does that work? If not, the command line parser is failing to interpret the 200x200 properly which most likely would indicate a compiler bug or C library bug.

Well, well.... it was a glibc issue.

The target device has libc.so.6 version 2.3.3 built with gcc 3.3.4 - the version on scratchbox is also 2.3.3 built with gcc 3.3.4 but still not the same.

after copying it to the target ImageMagick worked!

Thanks for your help!

can you tell me how you configure for you cross-compiling? thanks.
