Had problems bootstrapping Inline module 'test_pl_5d2c'

Can't find 'boot_test_pl_5d2c' symbol in/inlinecase/_Inline
/lib/auto/test_pl_5d2c/test_pl_5d2c.dll
at /usr/lib/perl5/site_perl/5.8/Inline.pm line 500


at ./test.pl line 0
INIT failed--call queue aborted.


程序:
use Inline C => Config => MYEXTLIB => /inlinecase/mylib.so';
use Inline C;



print (add(1,2));

__DATA__
__C__
int add(int x,int y)
{
        hello(1);
        return x+y;       
}

没人知道？
