I run: ../php-5.3.2/configure --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu --target=x86_64-redhat-linux-gnu make and get the same error. I do have libdl.so.2 in my lib64 directory. But if I apply the php-5.3.2-nolibdl-compile-error patch, does that mean that the PHP I compile will not be able to load extensions dynamically? ------------------------------------------------------------------------ [2010-03-11 18:08:41] tsteiner at nerdclub dot net 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 this bug report at http://bugs.php.net/bug.php?id=51276&edit=1
