i installed ImageMagick 7.1 via Chef/rpms using the ImageMagick.SPEC file in the 7.1 tar.gz

Imagemagick 7 use "magick" rather than "convert". Also try giving the full path to magick for where you installed Imagemagick 7.

Do you have two versions of IM installed?

What do you get from

Code: Select all

type -a convert

or

Code: Select all

type -a magick

[kamal2222ahmed]

$type -a convert
convert is /usr/bin/convert

$ type -a magick
magick is /usr/bin/magick

[kamal2222ahmed]

also:
$ which convert
/usr/bin/convert

[ec2-user@el2-ft110-app1 ~]$ which magick

Sorry, I do not see any difference and do not know why it is failing.

Is it the very same PDF image or a copy run from each account? Perhaps one copy is bad?

It looks like a permission issue to access the file from the first account.

[kamal2222ahmed]

could this be due to the fact that if we see ImageMagick.SPEC , the required RPMs are ALL -devel versions:

BuildRequires: bzip2-devel, freetype-devel, libjpeg-devel, libpng-devel
BuildRequires: libtiff-devel, giflib-devel, zlib-devel, perl-devel >= 5.8.1
BuildRequires: ghostscript-devel, djvulibre-devel
BuildRequires: libwmf-devel, jasper-devel, libtool-ltdl-devel
BuildRequires: libX11-devel, libXext-devel, libXt-devel
BuildRequires: lcms2-devel, libxml2-devel, librsvg2-devel, OpenEXR-devel
BuildRequires: fftw-devel, OpenEXR-devel, libwebp-devel
BuildRequires: jbigkit-devel
BuildRequires: openjpeg2-devel >= 2.1.0


but i have installed NON-DEVEL binary rpms ?

Sorry, I do not know much about installation on Linux

I've never seen convert try to create a file with the same name as in input PDF.

I suppose it tries to run Ghostscript. "-verbose" as the first option should tell you. Can both users run standalone Ghostscript?

"-debug all" may say where it is failing.
