Description:
------------
Hi phper, There's a trouble with my extension, I just make a sample extension. compile is ok, but when i use ld() function to load my extension, it tells me that 'php: symbol lookup error: /usr/local/lib/php/extensions/no-debug-non-zts-20060613/tintin.so: undefined symbol: init_array'. I don't know why, can you help me? My php version is 5.2.17 and system is Ubuntu Server 64

Test script:
---------------
PHP_FUNCTION(tintin_split){
        zval *new_chars;
        init_array(new_chars);
}

I use this command to compile as follow:

cc -fpic -DCOMPILE_DL_TINTIN=1 -I/usr/local/include -I. -I../.. -I../../Zend -I../../main -I../../TSRM -c -o tintin.o tintin.c
cc -shared -L/usr/local/lib -L/usr/local/lib/php -L/usr/lib -L. -rdynamic -o tintin.so tintin.o
cp tintin.so /usr/local/lib/php/extensions/no-debug-non-zts-20060613/

plz *DO NOT* send your own question to bug-web, pecl-dev mail list is which you 
should trun to.

and for you question, as a comment, use -Wall, you will see a implicit declaration 
of function, 

and btw you should use php_ext_skel to generate/compile extension
