This article mainly explains "how to install GD under linux". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to install GD under linux.

Before installing GD, you need to install jpeg-6b, libpng, zlib, freetype. The following is the download URL:

Download http://www.libgd.org/Downloads GD

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

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

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

Download http://www.freetype.org/ freetype

1. Install zlib

Tar zxvf zlib-1.2.3.tar.gz

Cd zlib-1.2.3

. / configure

Make

Make install

two。 Install libpng

Tar zxvf libpng-1.2.29.tar.gz

Cd libpng-1.2.29

Cd scripts/

Mv makefile.linux.. / makefile

Cd..

Make

Make install

Note that the makefile here is not generated with. / configure, but is copied directly from scripts/.

3. Install freetype

Tar zxvf freetype-2.1.10.tar.gz

Cd freetype-2.1.10

. / configure

Make

Make install

4. Install Jpeg

Tar zxvf jpegsrc.v6b.tar.gz

Cd jpeg-6b/

. / configure-- enable-shared

Make

Make test

Make install

Note that configure must take the-- enable-shared parameter here, otherwise, no shared library will be generated.

5. Install GD

Tar zxvf gd-2.0.33.tar.gz

Cd gd-2.0.33

. / configure-- with-png-- with-freetype-- with-jpeg

Make install

If GD reports an error: configure.ac:64: warning: macro `AM_ICONV' not found in library

Just make clean for a moment, and then make.

If you install something else and libtool is not found, you can just come and use it from / usr/bin/libtool cp!

Compile GD under 64-bit if / 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

This shows that zlib does not use-fPIC to compile and modify zlib's Makefile CFLAGS=-O3-DUSE_MMAP-fPIC.

Make;make install and then compile gd and then it's over!
