#19937 [NEW]: dynamic extension loading fails

From: ryan.smith@openwave.com Operating system: AIX 5.1 PHP version: 4.2.3 PHP Bug Type: Dynamic loading Bug description: dynamic extension loading fails Attempting to dynamically load a module fails under AIX. The error message is: PHP Warning: Unable to load dynamic library '/usr/HTTPServer/libexec/firstmod.so' - Invalid argument in Unknown on line 0 This indicates that the failure occurs during the DL_LOAD. The module does exist, and can be loaded with dlopen() in a test program. PHP is being loaded as a dynamic module within the IBM HTTP server (based on Apache 1.3.12). PHP was configured with: CC='cc_r' \ CXX='xlC_r -E' \ './configure' \ '--enable-c9x-inline' \ '--enable-shared' \ '--with-apxs=/usr/HTTPServer/bin/apxs' \ '--without-mysql' \ '--with-ldap=/users/rysmith/apache/openldap-2.0.25_AIX' I've tried compiling the module in many ways: (Simple) cc -c test2.c cc -G -o firstmod.so test2.o (from sample IBM DSO makefile) xlC_r -c -I /users/rysmith/apache/php-4.2.3/Zend -I /users/rysmith/apache/php-4.2.3 -I/users/rysmith/apache/php-4.2.3/main -I/users/rysmith/apache/php-4.2.3/TSRM -DAIX=42 -U__STR__ -DAIX_BIND_PROCESSOR -DUSE_HSREGEX -O2 -DSHARED_MODULE firstmod.c && mv firstmod.o firstmod.lo ld -H512 -T512 -bhalt:4 -bM:SRE -bnoentry -bI:/users/rysmith/apache/php-4.2.3/ext/ryan/libphp4.exp -bE:`echo firstmod.so|sed -e 's:\.so$:.exp:'` -lc -o firstmod.so firstmod.lo Attempting to load the module from within a PHP script also fails in the same way. -- Edit bug report at http://bugs.php.net/?id=19937&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19937&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19937&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19937&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19937&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19937&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=19937&r=support Expected behavior: http://bugs.php.net/fix.php?id=19937&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=19937&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=19937&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19937&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=19937&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=19937&r=dst IIS Stability: http://bugs.php.net/fix.php?id=19937&r=isapi
