Why ? Previous Comments: ------------------------------------------------------------------------ [2002-09-09 10:49:23] sniper@php.net If you do 'ldd libphp4.so' is there libz in the listing? (that's the library for uncompress) And about the GD problems..are you sure you don't have different versions of GD installed in your system? ------------------------------------------------------------------------ [2002-09-09 08:26:41] pitrou@free.fr Well, after adding /usr/local/lib and doing ldconfig, I still get the error (which is in fact normal as /usr/local/lib is almost empty - for instance libgd.so is in /usr/lib which is already mentioned in /etc/ld.so.conf). A strange thing is that php-4.0.6 (compiled on the same machine with the same configure options) has no problems at all. Also, please note that Apache (version 1.3.26, BTW) is compiled with SSL support. ------------------------------------------------------------------------ [2002-09-09 08:12:24] sniper@php.net You propably don't have /usr/local/lib in /etc/ld.so.conf ? If not, add it and run /sbin/ldconfig and it should all be okay then.. ------------------------------------------------------------------------ [2002-09-09 08:05:31] pitrou@free.fr Hello, I've tried to upgrade from 4.0.6 to 4.2.3, both versions compiled from source. Although I've used the same options for 4.2.3 as for 4.0.6, when I try to restart Apache I have an error message. It seems it doesn't link to the needed extension libs. # apachectl configtest Syntax error on line 182 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/libexec/libphp4.so: undefined symbol: gdImagePngCtx Here is the configure command : ./configure --with-apxs \ --with-mysql=/usr/local \ --with-bz2 \ --with-zlib \ --with-gd \ If I remove --with-gd, I have a similar error message : # apachectl configtest Syntax error on line 182 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/libexec/libphp4.so: undefined symbol: uncompress So it is not a problem with GD but rather with the way PHP loads extensions. Is there anything I overlooked in the build/configuration process ? Or is it really a bug ? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19314&edit=1
