Version: 1.8.2
os: gentoo
imagemagick: 7.0.5.7

run gscan2pdf from command line:

gene@go3:~# gscan2pdf

Not sure what "required ImageMagick libraries are not installed or not installed properly" this means. Any insight wil be appreciated.

I thing this is the symbol table of Q16.so:

Symbol table '.dynsym' contains 12 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND

It looks as though the perl bindings for imagemagick are broken. On Gentoo, rebuilding imagemagick should fix it.

Thanks Jeffrey. Tried this more than once. Changed the quantum depth to 32 and got this:

Can't find 'boot_ImageMagickQ32'.

Same as before only 32 instead of 16.

Thanks

Have you switched on the perl use flag for imagemagick? You'll need that.

[Gene]

My use flags:
[ebuild R ] media-gfx/imagemagick-7.0.5.7-r1:0/7.0.5.7::gentoo USE="X bzip2 corefonts cxx jpeg lcms openmp pango perl png q32 svg tiff truetype xml zlib -autotrace -djvu -fftw -fontconfig -fpx -graphviz -hdri -jbig -jpeg2k -lqr -lzma -opencl -openexr -postscript -q8 -raw -static-libs {-test} -webp -wmf" 0 KiB

Can see any here that need to be enabled? 'perl was already enbled.

Thanks

I'm guessing that removing q32 might fix it, as this is probably forcing q32 quantum depth, and perlmagick wants 16.
