Remove the tttest from the All:ttlib tttest ttpo 2. Delete Install CD $ (FTLIBDIR); $ (make)-F $ (MAKEFILE) Install CD $ (FTTESTDIR); $ (make)-F $ (MAKEFILE) Install CD $ (FTPODIR); $ (make) Install In the CD $ (FTTESTDIR); $ (make)-F $ (MAKEFILE) Install #./configure--prefix=/usr/local/freetype # Make && make install Copy Code 4, installation libpng # tar Xvzf libpng-1.5.2.tar.gz # CD libpng-1.5.2 #./configure--prefix=/usr/local/libpng # Make && make install Copy Code 5, Installation 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, should be the program can not automatically create folders, according to the error of the prompt, hand-use mkdir create files on it. 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 Code 6, install GetText (some directly have, you can install the GD library, error and then return to install) # tar Xvzf gettext-0.16.1.tar.gz # CD gettext-0.16.1 #./configure--prefix=/usr/local/gettext # Make && make install Copy Code 7. Install 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 ... Possible error in this step: configure.ac:64:error:possibly undefined macro:am_iconv, this must be installed GetText (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 Code At the end of make install there will be the location of GD inventory, from that folder to copy gd.so to the extension library directory 9, modify php.ini in the php.ini add the following content Extension=gd.so Copy Code 10. End of installation, restart Apache Service # Service httpd Restart Copy Code
