完整linux下配置RMagick步骤 解决RMagick.so cannot open shared object问题

如果你在安装RMagick的时候碰到类似这样的错误:

1RMagick.so: libWand.so.10: cannot open shared object file: No such file or directory -
问题应该是出在共享库的路径上..所以可以尝试在configure之前,先声明路径:

11)export LD_LIBRARY_PATH=/usr/local/lib

22)added "/usr/local/lib" to /etc/ld.so.conf , then

然后再configure , make ,make install..

送上我在linux上安装RMagick的步骤和经验..这个模块装起来也确实麻烦的很..需要的东西很多..而且路径问题折腾了我好久...闲话不说..下面是步骤

---------------------------------------------------------------------------------------------------

先来安装RMagick 的前提,就是下面这些个模块...

1)安装libjpg

wget http://www.ijg.org/files/jpegsrc.v6b.tar.gz

tar -xzvf jpegsrc.v6b.tar.gz

cd jpeg-6b/

./configure --enable-shared

make

make test

make install

2)安装libpng

wget http://easynews.dl.sourceforge.net/sourceforge/libpng/libpng-1.2.16.tar.bz2

tar -xvjf libpng-1.2.16.tar.bz2

./configure

make check

3)安装Freetype

wget http://superb-west.dl.sourceforge.net/sourceforge/freetype/freetype-2.3.2.tar.bz2

tar -xjvf freetype-2.3.2.tar.bz2

cd freetype-2.3.2

make

make

cp objs/.libs/*.so* /usr/local/lib/

cp -rv include/* /usr/local/include/

4)安装Ghostscript

wget http://umn.dl.sourceforge.net/sourceforge/ghostscript/ghostscript-8.54-gpl.tar.bz2

tar xjvf ghostscript-8.54-gpl.tar.bz2

cd ghostscript-8.54-gpl

./configure

make

make install

5）安装Ghostscript fonts

wget http://internap.dl.sourceforge.net/sourceforge/gs-fonts/ghostscript-fonts-std-8.11.tar.gz

tar -xvzf ghostscript-fonts-std-8.11.tar.gz

cp -rv fonts /usr/local/share/ghostscript/

6）安装ImageMagick

wget ftp://ftp.fifi.org/pub/ImageMagick/ImageMagick-6.3.2-9.tar.bz2

tar -xjvf ImageMagick-6.3.2-9.tar.bz2

cd ImageMagick-6.3.2

./configure --without-perl --without-magick-plus-plus

export PATH=$PATH:/usr/local/ImageMagic/bin

编辑:/etc/ld.so.conf,加入

/usr/local/ImageMagick/lib

执行：ldconfig 查看是否有异常..

确定有以下的配置信息出现：

Ghostscript None gs (8.54)

FreeType --with-freetype=yes yes

JPEG v1 --with-jpeg=yes yes

PNG --with-png=yes yes

接着，make install(run as root)

如果在安装后，系统报字体找不到，把usr/share/fonts/type1字体考到目录/usr/share/ghostscript/fonts/，就可以了。

---------------------------------------------------------------------------------------

至此结束了RMagick的前面步骤...现在就开始了RMagick的安装...比较简单了...你可以选择两种方式:

1. gem安装

gem install rmagick

成功后提示:

Bulk updating Gem source index for: http://gems.rubyforge.org
Building native extensions. This could take a while...

Successfully installed rmagick-X.Y.Z

2. 源码安装:

1) export LD_LIBRARY_PATH=/usr/local/lib

2) added "/usr/local/lib" to /etc/ld.so.conf , then

3) ./configure

4) make && make install

至此RMagick安装结束..

现在来测试下RMagick是否安装成功

irb -rubygems -r RMagick

irb(main):001:0> puts Magick::Long_version 如果输出一下信息则代表OK:
