linux下編譯GD（freetype+libjpeg+libpng+gd-devel）

1、檢查freetype是否安裝
rpm -qa | grep freetype
沒有的話編譯freetype 這裡下載
./configure --prefix=/usr/local/freetype
make && make install 即可，沒有花頭
2、檢查libjpeg是否安裝
rpm -qa | grep libjpeg
沒有的話編譯libjpeg 這裡下載
我也沒裝libjpeg，下載好開始編譯
jpegsrc.v6b.tar.gz
tar -xzvf jpegsrc.v6b.tar.gz
cd jpeg-6b/
./configure --prefix=/usr/local/jpeg --enable-shared
make && make install
最後一步make install 出錯：
/usr/bin/install -c -m 644 jconfig.h /usr/local/jpeg/include/jconfig.h
/usr/bin/install: cannot create regular file `/usr/local/jpeg/include/jconfig.h': No such file or directory
make: *** [install-headers] Error 1
/usr/bin/install: cannot create regular file `/usr/local/jpeg/lib/libjpeg.so.62.0.0': No such file or directory
/usr/bin/install: cannot create regular file `/usr/local/jpeg/bin/cjpeg': No such file or directory
make: *** [install-lib] Error 1
難道安裝程式自己建立一下目錄都不行？？暈，我自己去建立目錄
mkdir -p /usr/local/jpeg/include
mkdir -p /usr/local/jpeg/lib
mkdir -p /usr/local/jpeg/bin
mkdir -p /usr/local/jpeg/man/man1
OK再編譯就成功了
3、檢查是否安裝了libpng
rpm -qa libpng
沒有的話編譯libpng 這裡下載
./configure --prefix=/usr/local/png
make && make install
4、安裝GD庫 這裡下載
tar -zxvf gd-2.0.35.tar.gz
cd gd-2.0.35
./configure --prefix=/usr/local/gd2
5、編譯PHP 這裡下載
tar -zxvf php-5.2.5.tar.gz
cd php-5.2.5
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-zlib --with-jpeg-dir=/usr/local/jpeg --with-png-dir=/usr/local/png --with-freetype-dir=/usr/local/freetype --enable-ftp --enable-sockets --with-gd=/usr/local/gd2 --enable-gd-native-ttf --with-ttf --enable-magic-quotes --with-iconv -enable-mbstring=all
OK 全部完成
PS：如果安裝有報錯:
configure.ac:64: error: possibly undefined macro: AM_ICONV
    If this token and others are legitimate, please use m4_pattern_allow.
    See the Autoconf documentation.
make: *** [configure] Error 1
需要安裝gettext 這裡下載
