Yes and I have partial solution. Not pretty though but it works for me at least.
So, problem caused by several things:
1. Build environment for self contained extensions (SCE) is generally broken
in PHP4. It wasn't work in past, it does not work now in one
particular case: when you have several PHP_ARG_WITH or PHP_ARG_ENABLE
in config.m4. In case of SCE, all of these macroses get positive
answer regardless of user input or library checks because of this code
in PHP_ARG_ANALYZE (acinclude.m4):
if test "$php_always_shared" = "yes"; then
ext_output="yes, shared"
ext_shared=yes
test "[$]$1" = "no" && $1=yes
fi
So, even if user states PHP_SOMETHING = no, this code will rewrite it to
PHP_SOMETHING = yes
This particulary touches 'readline', 'mysql', 'dba', 'interbase',
'mcrypt', 'mhash' and other extensions.
2. PHP-GTK suffers from other bug. It is also a problem with build
environment: when you do
#include "php_config.h"
in SCE module, then main PHP4 php_config.h which is installed on the
system is included, not locally created php_config.h which contains
proper definitions of HAVE_PHP_GTK and COMPILE_DL_PHP_GTK symbols.
In the CVS version of PHP4 header file which is generated as SCE config
file is renamed to config.h from php_config.h few days ago. But modules
themselves were not updated, so there are no modules in PHP4 than really
include config.h from the current directory, so HAVE_MODULENAME will be
undefined for all of them (if they are compiled as SCE) and all code
will be skipped due
#if HAVE_MODULENAME
<actual code>
#endif
in most of them.
This particulary touches PHP-GTK, mysql, dba, and most of other modules.
Solution for PHP-GTK is to pass -DHAVE_PHP_GTK=1 -DCOMPILE_DL_PHP_GTK=1 to configure
through CFLAGS. Or fix SCE build environment (macros in acinclude.m4, pear/pear.m4
and #include "php_config.h" in all modules).
