I am trying to use the Image functions within php.

example - imagefontwidth

I get this error

Fatal error: Call to undefined function: imagefontwidth() in _________ on line 10

So I read that I need to install the GD libraries when I configure PHP.

I have version 4.4.1 of PHP running.

the php documentation indicates the gd lib is included and I should use configure --with-gd so I did that.

./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-gd

I then read this

To enable GD-support configure PHP --with-gd[=DIR], where DIR is the GD base install directory. To use the recommended bundled version of the GD library (which was first bundled in PHP 4.3.0), use the configure option --with-gd. GD library requires libpng and libjpeg to compile.

this is where I need help...where do I put these files and what should the list look like.

Let me start there.

Thanks

Which distro is it you're using?
You can get the libraries and configure && make && make install them, as usual programs. Or run emerge / apt-get / whatever is applicable to your distro to get them.
http://www.libpng.org/pub/png/libpng.html - libpng
http://www.ijg.org/ - libjpeg
http://www.remotesensing.org/libtiff/ - libtiff (can also come in handy)

I have all these files downloaded along with zlib, as it is required also.

I did configure, make test, and make install for the zlib and the png...and the test passed. Now the JPEG part I am not sure about. I am uncertain what I need to do to get this configured right.

I did configure, make test...but I really dont know if it is working right....didnt say passed test like the other groups.




So if it is working what does my configure statement look like for the PHP....and how do I know it is working right.

./configure --with-gd --with-jpeg ????????????????

I am not good at this part unless the cookbook works and the details are exacting.

OK, I have the functions working now.

I did
configure
make
make test
make -n install

for zlib, png, jpeg


then I used this configure statement for php

[root@localhost /php441]# ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql -with-gd --with-jpeg-dir=/usr/bin/install --with-zlib-dir=user/bin/install --with-png-dir=/usr/bin/install

I still get the following errors when I test the make.

php image functions that I use work....but what are all these errors about?

Thanks for reading and thanks for helping

It has to do with the older version of libraries that don't support some things properly.
