#19314 [NEW]: unable to startup Apache (undefined symbol)

From: pitrou@free.fr Operating system: Linux 2.4.19 PHP version: 4.2.3 PHP Bug Type: Apache related Bug description: unable to startup Apache (undefined symbol) 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 bug report at http://bugs.php.net/?id=19314&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19314&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19314&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19314&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19314&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19314&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=19314&r=support Expected behavior: http://bugs.php.net/fix.php?id=19314&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=19314&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=19314&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19314&r=globals
