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
