在32位Centos6.4上安装GraphicsMagick

安装时，make总是有如下错误，最后几行
/bin/sh ./libtool  --tag=CC   --mode=link gcc -std=gnu99  -g -O2 -Wall -pthread -ldl -L/usr/lib -L/usr/lib -ldl -L/usr/lib -L/usr/lib -o utilities/gm utilities/gm.o magick/libGraphicsMagick.la

解决方法：

详细的安装步骤，需要把之前安装的libz换成最新：

#cd zlib-1.2.
#CFLAGS="-O3 -fPIC" ./configure --prefix=/usr/local/zlib/
#make
# make install
#cp   /usr/local/zlib/lib/libz.so.1.2.  /usr/lib/
#unlink /usr/lib/libz.so
#link /usr/lib/libz.so.1.2. /usr/lib/libz.so
 ...
 ....
#cd GraphicsMagick-1.3.
#./configure
#make
#make install

安装之后报错

gm: /lib/libz.so.: version `ZLIB_1.2.3.' not found (required by gm)

解决办法：
　　

[root@localhost GraphicsMagick-1.3.24]# cp /usr/local/lib/libz.so.1 /lib/
cp：是否覆盖"/lib/libz.so.1"？ y

[root@localhost GraphicsMagick-1.3.]# gm -version
