hi yes i did try configuring using --with-gd=/usr/local/lib as this is where the libgd.so file is however i get the error

configure: error: Unable to find gd.h anywhere under /usr/local/lib

this file (gd.h) is held under /usr/local/include this is why i used /usr/local

is there anyway around this? can i simply move the file across?

Ah have you tried


You might try that. The other thing (this is how I usually compile programs, so it's easier to delete them if I need too) is you could recompile gd this way:

Then use this with PHP:

I've done that in the past with success.

Hi yes i have tried installind gd with the /usr/local/include path however it then complains it can find other file.

I've done as you said. I compiled gd with --prefix=/usr/local/gd, make, make install
this went ok

i then compiled php with --with-gd=/usr/local/gd, this worked ok too!

however when i ran make i recieve the error
ext/gd/.libs/gd.o: In function `php_image_filter_smooth':

( I included a small amount of the cod ebefore as i dont think its finding the functions in my gd)

any ideas.

also i'd just like to thank you for all your help so far.

Matt.

Mmmmmm....there might be some stuff left over from your old compiles of PHP. Try this:

cd into_your_php_dir
make clean
./configure --with-gd=/usr/local/gd
make
make install

My thought is PHP might be looking for functions in the wrong place. Give that a whirl and see if you have the same errors.

Hi sorry for the late reply i've been tied up in other business recently. ok this seems to have sorted something out however i still get the following error on compilation

ext/gd/.libs/gd.o: In function `zif_imagecreatefromstring':
/home/matt/php-5.2.0/ext/gd/gd.c:2300: undefined reference to `gdImageCreateFromPngCtx'

do i need a png library to fix this?

Thanks Again, Matt.

Yeppers you'll need to have libpng:

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

It's probably installed with your Distro though. Or you could always compile it yourself. Then wherever you compile it to use:
When you compile gd. After you've compiled gd with png support you'll need to recompile PHP with gd support. Kind of a dependency issue, but I think you're getting really close.

There's also a jpeg library you might want to use with gd:

http://www.ijg.org/

After you compile it enable it with:

Ok i installed both now so here what i did

libpng 1.2.16

./configure --prefix=/usr/local/libpng
make
make install

for jpeg6b (libjpeg)

./configure (using default prefix /usr/local)
make
make install

i then used the following for the php5 configure after i've run make clean again

'./configure' '--with-mysql=/usr/local/mysql' '--without-sqlite' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-zlib' '--with-gd=/usr/local/gd' '--with-iconv-dir' '--with-png=/usr/local/libpng' '--with-jpeg=/usr/local'

this runs ok and thought it was there but now i get the following when i run make

ext/gd/.libs/gd.o: In function `zif_imagecreatefromstring':
/home/matt/php-5.2.0/ext/gd/gd.c:2300: undefined reference to `gdImageCreateFromPngCtx'

any ideas?

Did you rebuild gd? You'll want to rebuild gd with the png and jpeg options:

Then try rebuilding PHP with these options:
