安裝 GD 前需要安裝 jpeg-6b, libpng, zlib, freetype。以下是下载网址:

http://www.libgd.org/Downloads GD下载

ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz JPEG下载

http://www.libpng.org/pub/png/libpng.html png下载

http://www.zlib.net/zlib-1.2.3.tar.gz zlib下载

http://www.freetype.org/ freetype下载

1.安装zlib

tar zxvf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure
make
make install

2.安装libpng

tar zxvf libpng-1.2.29.tar.gz
cd libpng-1.2.29
cd scripts/
mv makefile.linux ../makefile
cd ..
make
make install
注意,这里的makefile不是用./configure生成,而是直接从scripts/里拷一个

3.安装freetype

tar zxvf freetype-2.1.10.tar.gz
cd freetype-2.1.10
./configure
make
make install

4.安装Jpeg

tar zxvf jpegsrc.v6b.tar.gz
cd jpeg-6b/
./configure --enable-shared
make
make test
make install
注意,这里configure一定要带--enable-shared参数,不然,不会生成共享库

5.安装GD

tar zxvf gd-2.0.33.tar.gz
cd gd-2.0.33
./configure --with-png --with-freetype --with-jpeg
make install

如果GD报错:configure.ac:64: warning: macro `AM_ICONV' not found in library
你就make clean一下,然后再make

如果你安装别的出现libtool没有找到,你就从/usr/bin/libtool cp 一个过来用就好了!

在64位下编译GD 如果/usr/bin/ld: /usr/local/lib/libz.a(compress.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
这说明zlib没用用-fPIC进行编译修改zlib的Makefile CFLAGS=-O3 -DUSE_MMAP -fPIC
make;make install然后再编译gd 就过去了!
