Shazam! Use Image::Magick with Perlbrew in minutes
The open source ImageMagick software provides amazing tools for creating and manipulating images in over 100 formats. Unfortunately, installing ImageMagick’s Perl module under Perlbrew can be a frustrating and time-consuming task. However it doesn’t have to be this way - with the method described below you can have the module installed in minutes, no root access required!
You’ll need to have Perlbrew and a local Perl installation via Perlbrew on Unix-based platform. This has been tested on Perl 5.16.3 but should work on any modern Perl version.
Create a local directory: we will install ImageMagick here. Open up the terminal and enter the following:
Installing Image::Magick - don’t use CPAN
Although the Image::Magick module is available on CPAN, installing it via CPAN is usually a fruitless task as the process croaks on make. Instead download the whole ImageMagick tarball. Once downloaded, navigate to the tarball’s parent directory using the terminal and un-tar the archive with the following command
tar xvfz ImageMagick.tar.gz
Now change into the new directory:
Enter the following command, replacing [username], [path to CORE] and [path to Perl bin] with your system’s details. Remove the “–without-threads” text if your Perl was compiled with threads (here is how to check).
LDFLAGS=-L/home/[username]/perl5/perlbrew/perls/[path to CORE] \ ./configure --prefix /home/[username]/local \ --with-perl=/home/[username]/perl5/perlbrew/perls/[path to Perl bin] \ --enable-shared --without-threads
Here is a completed example for my system:
LDFLAGS=-L/home/sillymoose/perl5/perlbrew/perls/perl-5.16.3/lib/5.16.3/x86_64-linux/CORE \ ./configure --prefix /home/sillymoose/local \ --with-perl=/home/sillymoose/perl5/perlbrew/perls/perl-5.16.3/bin/perl \ --enable-shared --without-threads
Running this command should cause ImageMagick to run a series of configuration checks, at the end of which it will print a configuration summary, which should look something like this:
ImageMagick is configured as follows. Please verify that this configuration matches your expectations. Host system type: x86_64-unknown-linux-gnu Build system type: x86_64-unknown-linux-gnu Option Value ------------------------------------------------------------------------------- Shared libraries --enable-shared=yes yes Static libraries --enable-static=yes yes Module support --with-modules=no no GNU ld --with-gnu-ld=yes yes Quantum depth --with-quantum-depth=16 16 High Dynamic Range Imagery --enable-hdri=no no Delegate Configuration: BZLIB --with-bzlib=yes yes Autotrace --with-autotrace=no no Dejavu fonts --with-dejavu-font-dir=default /usr/share/fonts/dejavu/ DJVU --with-djvu=yes no DPS --with-dps=yes no FFTW --with-fftw=yes no FlashPIX --with-fpx=yes no FontConfig --with-fontconfig=yes no FreeType --with-freetype=yes yes GhostPCL None pcl6 (unknown) GhostXPS None gxps (unknown) Ghostscript None gs (9.10) Ghostscript fonts --with-gs-font-dir=default /usr/share/fonts/default/Type1/ Ghostscript lib --with-gslib=no no Graphviz --with-gvc=no JBIG --with-jbig=yes no JPEG v1 --with-jpeg=yes yes JPEG-2000 --with-jp2=yes yes LCMS v1 --with-lcms=yes yes LCMS v2 --with-lcms2=yes no LQR --with-lqr=yes no LTDL --with-ltdl=yes no LZMA --with-lzma=yes yes Magick++ --with-magick-plus-plus=yes no (failed tests) MUPDF --with-mupdf=no no OpenEXR --with-openexr=yes no PANGO --with-pango=yes no PERL --with-perl=/home/sillymoose/perl5/perlbrew/perls/perl-5.16.3/bin/perl /home/sillymoose/perl5/perlbrew/perls/perl-5.16.3/bin/perl PNG --with-png=yes yes RSVG --with-rsvg=no no TIFF --with-tiff=yes yes WEBP --with-webp=yes no Windows fonts --with-windows-font-dir= none WMF --with-wmf=no no X11 --with-x= yes XML --with-xml=yes yes ZLIB --with-zlib=yes yes
Check that the image file formats you expect to be working with are showing as “yes”. If any are showing as “no” that you require, you’ll need to install the appropriate C library (e.g. libpng for PNG files) and re-run the previous command.
To install ImageMagick and the Image::Magick Perl module, run this command:
Confirming that the Image::Magick module has installed is not quite straightforward either. With version Image Magick 6.8.8, the $VERSION variable is stored in the super class Image::Magick::Q16. Hence you’ll need to type:
perl -MImage::Magick::Q16\ 999
Which should yield:
Image::Magick::Q16 version 999 required--this is only version 6.88.
