I'm using shared libgd.so.2.0.0 which supports jpeg, xpm, png and libz. Unfortunately php configure does NOT include
libpng and libz in its test, so it gets wrong results.
E.g.:

configure:15759: checking whether to include GD support
configure:16388: checking for gdImageString16 in -lgd
configure:16407: gcc -o conftest -g -O2  -DLINUX=2 -DMOD_SSL=206105 -DEAPI -DUSE

Support for GD was just added to the latest CVS.
Try a snapshot from snaps.php.net or checkout the latest CVS and configure with:

./configure 
"--with-jpeg-dir" \ 
"--with-png-dir" \ 
"--with-freetype-dir" \ 
"--with-gd" 

Beware - this will implicitly --enable-gd-native-ttf.

Please let me know how you get on.

--Wez.
 [2001-04-15 08:54 UTC] wez@php.net
Sorry - you also need --with-xpm-dir, and I meant to say GD 2.


 [2001-04-15 12:20 UTC] elkner at linofee dot org
Nope, --with-png-dir does not resolve the problem (that was
my first try). I can't use --with-freetype-dir, since freetype support is not part of the used gd lib.

Here the params I used:
./configure --prefix=/develop/sl7/proto/opt/php4 --with-apxs --enable-discard-path --with-config-file-path=/etc --enable-safe-mode --with-exec-dir=/opt/php/bin --with-openssl=/opt/ssl --enable-calendar --enable-ftp --with-gd=/usr/local --with-ldap --with-mysql --with-oci8=/opt/oracle --enable-sockets --with-regex=system --enable-sysvsem --enable-sysvshm --with-zlib=/usr/local --with-xpm-dir=/usr/X11R6 --with-jpeg-dir=/usr --enable-track-vars --with-png-dir=/usr

BTW: What for is the --with-sockets stuff (just for incl. of -lsockets ?)

 [2001-04-15 14:21 UTC] elkner at linofee dot org
I made a quick and dirty patch to configure, so that it
works:

Could you reverse your patch, and then:
rm config.cache
./configure
 --prefix=/develop/sl7/proto/opt/php4
 --with-apxs --enable-discard-path
 --with-config-file-path=/etc --enable-safe-mode
 --with-exec-dir=/opt/php/bin
 --with-openssl=/opt/ssl --enable-calendar
 --enable-ftp --with-ldap --with-mysql
 --with-oci8=/opt/oracle --enable-sockets
 --with-regex=system --enable-sysvsem
 --enable-sysvshm --with-zlib=/usr/local
 --with-xpm-dir=/usr/X11R6
 --with-jpeg-dir=/usr
 --enable-track-vars
 --with-png-dir=/usr
 --with-gd=/usr/local 

Let me know if it works; if it does not, I would like to see your config.log to find out what is going on.

BTW: --with-sockets enables the sockets extension - you probably don't need it.

User Reported:
-----------------
Works for some parts, but not all:
checking whether to include GD support... yes (static)
checking for gdImageString16 in -lgd... no
checking for gdImagePaletteCopy in -lgd... no
checking for gdImageColorClosestHWB in -lgd... no
checking for compress in -lz... no
checking for png_info_init in -lpng... yes
checking for gdImageColorResolve in -lgd... yes
checking for gdImageCreateFromPng in -lgd... yes
checking for gdImageCreateFromGif in -lgd... no
checking for gdImageWBMP in -lgd... yes
checking for gdImageCreateFromJpeg in -lgd... yes
checking for gdImageCreateFromXpm in -lgd... yes

To whom should I send the config.log? It is uncompressed about 120K,
compress about 11K - so probably not suitable for a mailing list?

Regards,
jens.

BTW: Any hints how to trace that problem:

# /etc/init.d/apachectl-1.3.19 start
Syntax error on line 233 of /opt/www/conf/httpd.conf:
API module structure `php4_module' in file /opt/www/libexec/libphp4.so is garbled - perhaps this is not an Apache module DSO?
/etc/init.d/apachectl start: httpd could not be started
-----------------

Please email me the config.log to mailto:wez@php.net

The garbled module problem is technically a different bug; I would suggest ensuring that gd links in correctly (or building without) and making sure that you do "./cvsclean; ./buildconf" before you configure.

Try latest CVS. If that doesn't work for you, reopen.
