CentOS 기준으로 ImageMagick를 설치해보자.
의존성 모듈 설치
# yum install -y tcl-devel libpng-devel libjpeg-devel
# yum install -y ghostscript-devel bzip2-devel freetype-devel libtiff-devel zlib-devel
# yum install -y ImageMagick-c++ ImageMagick-c++-devel
imagemagick 설치
참고 사이트 http://www.imagemagick.org/script/install-source.php#unix
(configure시 CXX=CC CXXFLAGS=-O2 옵션을 주어 magicK++을 함께 설치한다)
# wget http://www.imagemagick.org/download/ImageMagick.tar.gz
# tar xvzf ImageMagick.tar.gz
# cd ImageMagick-7.0.4-0
# ./configure CXX=CC CXXFLAGS=-O2 --prefix=/usr/local
# make clean
# make
# make install
# /sbin/ldconfig /usr/local/lib
# /usr/local/bin/convert logo: logo.gif
# make check
