Hi!
I'm using PHP 4.2.0 on MandrakeLinux Cooker (post 8.2).
When I use the RPM of PHP 4.2.0 which is compiled like so:
%define external_modules bcmath bz2 calendar curl dba_bundle dbx dbase
exif filepro ftp gd gettext gmp imap ldap libphp_java mcrypt mhash ming
mysql odbc pdf pgsql posix readline recode session sablot shmop snmp
sybase sysvsem sysvshm unixODBC t1lib yp zlib zip xml xslt domxml
vpopmail pspell
./configure \
--disable-static \
--disable-debug \
--disable-rpath \
--enable-pic \
--enable-inline-optimization \
--prefix=%{_prefix} \
--with-config-file-path=%{_sysconfdir} \
--enable-magic-quotes \
--enable-debugger \
--enable-track-vars \
--enable-session \
--with-exec-dir=%{_bindir} \
--with-versioning \
--with-mod_charset \
--with-expat-dir=%{_prefix} \
--with-regex=php \
--without-dba \
--without-gdbm \
--without-db2 \
--without-db3 \
--enable-force-cgi-redirect \
--enable-track-vars \
--enable-trans-sid \
--enable-safe-mode \
--with-ctype \
--with-ttf \
--with-freetype-dir=%{_prefix} \
--with-openssl=%{_prefix} \
--without-aspell \
--without-kerberos \
`for i in %{external_modules}; do echo --without-${i} --disable-${i}; done`
As you can see, that's ripped from the SPEC file for the RPM. Mandrake
tries to build the main PHP binary/mod_php with as little support for
anything as possible and compiles everything needed as external modules.
The mysql.so extension is compiled like this:
%{phpsource}/buildext mysql php_mysql.c "-lmysqlclient_r -lmysqlclient
-lpthread -lz" \
"-DCOMPILE_DL_MYSQL -DHAVE_MYSQL"
recode.so is compiled like this:
%{phpsource}/buildext recode recode.c "/usr/lib/librecode.a
-lrecode" \
"-DCOMPILE_DL_RECODE -DHAVE_LIBRECODE -L/usr/lib"
Everything get's compiled with no error messages at all. However, when
I enable both mysql.so and recode.so in php.ini like below, php (binary)
dumps core:
extension=mysql.so
extension=recode.so
However, when I change the order (ie. I enable the recode.so extension
before mysql.so), PHP starts up just fine.
I noticed this behaviour in 4.1.2 and 4.2.0. I'm not sure if other
versions are affected as well.
Any ideas about why this is happening? Below is a strace of a dumping
php. Here's a backtrace of the same PHP:
