Come installare rmagick su Ubuntu 10.04?

Ecco cosa ho fatto finora:

sudo apt-get install imagemagick libmagickcore-dev

Questo non ha generato alcun errore, quindi penso che ImageMagick sia installato correttamente. Quindi ho provato a installare la gemma:

sudo gem install rmagick

Ciò ha comportato il seguente errore:

ERROR:  Error installing rmagick:
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/usr/bin/ruby1.8


Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/rmagick-2.13.1 for inspection.

Cosa devo fare per installare rmagick su Ubuntu 10.04?

Penso che anche tu debba installare libmagickwand-dev dall'archivio ubuntu:

sudo apt-get install libmagickwand-dev

Questo pacchetto contiene il file MagickWand.h.

sudo apt-get install libmagickwand-dev imagemagick

Ho fatto il seguente passo per costruire dalla fonte

> wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
> tar -xzvf ImageMagick.tar.gz
> ./configure --prefix=/usr/local --with-x=no --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --disable-openmp
> make
> sudo make install
> sudo /sbin/ldconfig /usr/local
> sudo ln -f /usr/local/bin/Magick-config /usr/bin/Magick-config
> sudo PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ gem install rmagick

Risultato

Building native extensions.  This could take a while...

Ho avuto un problema simile e mi sono imbattuto in questo post: http://www.question-defense.com/2010/05/18/centos-linux-cant-install-rmagick-2-7-0-cant-find-magick -config

Dopo aver installato libmagick9-dev ho potuto installare rmagick gem senza problemi. Spero che sia di aiuto.

1. aptitude install imagemagick
2. aptitude install perlmagick

Secondo queste istruzioni .
