# tar xvzf zlib-1.2.3.tar.gz
# cd zlib-1.2.3
# ./configure
# make && make install

Copy the code

3. Install freetype

# tar xvzf freetype-1.3.1.tar.gz
# cd freetype-1.3.1
# ./configure --prefix=/usr/local/freetype
# make && make install

Copy the code

There are multiple lines of errors similar to: ftdump.c:172:1: error: pasting "." and "glyph_object" does not give a valid preprocessing token

Solution: Modify the code in test/ftdump.c: Change Print_Mem( memory_footprint.##field, string ) to: Print_Mem( memory_footprint.field, string ) Change #define FOOTPRINT( field ) Save_Memory( &memory_footprint.##field ) to: #define FOOTPRINT( field ) Save_Memory( &memory_footprint.field ) Remake && make install Or modify Makefile.in:

1. Remove all: tttest in ttlib tttest ttpo
2. Delete
install:
cd $(FTLIBDIR); $(MAKE) -f $(MAKEFILE) install
cd $(FTTESTDIR); $ (MAKE) -f $(MAKEFILE) install
cd $(FTPODIR); $(MAKE) install
cd $(FTTESTDIR); $(MAKE) -f $(MAKEFILE) install
# ./configure --prefix =/usr/local/freetype
# make && make install

Copy code

4. Install libpng

# tar xvzf libpng-1.5.2.tar.gz
# cd libpng-1.5.2
# ./configure --prefix=/usr/local/libpng
# make && make install

Copy the code

5. Install jpegsrc

# tar xvzf jpegsrc.v6b.tar.gz
# cd jpegsrc.v6b
# ./configure --prefix=/usr/local/jpeg6 –enable-shared –enable-static
# make && make install

Copy code

Possible error: The prompt folder does not exist. It should be that the program cannot automatically create the folder. According to the error prompt, just create the file manually with mkdir. This time for example:

# mkdir -p /usr/local/jpeg6/include/
# mkdir -p /usr/local/jpeg6/lib/
# mkdir -p /usr/local/jpeg6/bin/cjpeg
# mkdir -p /usr/local/jpeg6/man/man1/

Copy the code

6. Install gettext (some have it directly, you can install the GD library first, report an error and then return to install it)

# tar xvzf gettext-0.16.1.tar.gz
# cd gettext-0.16.1
# ./configure --prefix=/usr/local/gettext
# make && make install

Copy the code

7. Install the GD library

# tar xvzf gd-2.0.35.tar.gz
# cd gd-2.0.35
# ./configure --prefix=/usr/local/gd --with-jpeg=/usr/ local/jpeg6 --with-png=/usr/local/libpng --with-freetype=/usr/local/freetype
# make
# make install

Copy code

configure...This step is possible Error: configure.ac:64: error: possibly undefined macro: AM_ICONV, you must install gettext (discussed in step 6)

8. Generate gd.so

# cd ../php-5.2.17/ext/gd/
#/usr/local/php5/bin/phpize
#./configure --with-php-config=/usr/local /php5/bin/php-config --with-jpeg-dir=/usr/local/jpeg6/ --with-png-dir=/usr/local/libpng/ --with-gd=/usr/local/gd / --with-freetype-dir=/usr/local/freetype/
# make && make install

Copy the code

At this time, at the end of make install, there will be the location where the gd library is stored, from that folder Copy gd.so to the extension library directory

9. Modify PHP.ini Add the following content to php.ini

extension=gd.so

Copy the code

10. After the installation is completed, restart the Apache service

# service httpd restart

Copy code
