Bug #51276 [NEW]: php_load_extension is called when HAVE_LIBDL is not defined.

From: Operating system: Linux PHP version: 5.3.2 Package: Compile Failure Bug Type: Bug Bug description:php_load_extension is called when HAVE_LIBDL is not defined. Description: ------------ When HAVE_LIBDL is not defined in main/php_config.h, the function php_load_extension is not compiled in ext/standard/dl.c. However, the function php_load_php_extension_cb() will always be compiled with a call to php_load_extension. This causes compilation to fail with the following message: main/php_ini.o: In function `php_load_php_extension_cb': [path removed]/main/php_ini.c:350: undefined reference to `php_load_extension' collect2: ld returned 1 exit status make: *** [sapi/cli/php] Error 1 This appears to be the only place php_load_extension is called. Furthermore, php_load_php_extension_cb is only referenced by php_ini_register_extensions(), which is only called in at main/main.c:2021. It would seem that on architectures that don't HAVE_LIBDL, the preceding functions should be inside #if defined() checks. I found this bug while cross-compiling from x86_64 to powerpc but I don't believe it is a cross-compiling issue. Test script: --------------- CC=${CROSS_COMPILE}gcc ../php-5.3.2/configure --host=powerpc-unknown-linux make Expected result: ---------------- PHP should compile without errors. Actual result: -------------- main/php_ini.o: In function `php_load_php_extension_cb': [path removed]/main/php_ini.c:350: undefined reference to `php_load_extension' collect2: ld returned 1 exit status make: *** [sapi/cli/php] Error 1 -- Edit bug report at http://bugs.php.net/bug.php?id=51276&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51276&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51276&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51276&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51276&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51276&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51276&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51276&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51276&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51276&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51276&r=support Expected behavior: http://bugs.php.net/fix.php?id=51276&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51276&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51276&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51276&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51276&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51276&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51276&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51276&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51276&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51276&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51276&r=mysqlcfg
