[asterisk-dev] Compiling Module outside of source tree

[Joe Lewis]

Hello;

I am new to this list, simply because I have had a question.  I want to 
get into module development for asterisk, and I've run into an "issue".  
Hopefully, it should be quick.

For my first task, I thought I'd reinvent the wheel, and create a simple 
MySQL CDR plugin.  However, every time I restart asterisk, I get the 
message :

[Sep 10 13:57:55] WARNING[3315]: loader.c:376 load_dynamic_module: 
Module 'cdr_mysql.so' did not register itself during load
[Sep 10 13:57:55] WARNING[3315]: res_crypto.c:480 crypto_load: Unable to 
open key directory '/usr/share/asterisk/keys'

I haven't even attempted to add the MySQL functionality (almost a "hello 
world"), so I'm starting very basic.  I've created a load() function, 
and an unload() function, along with the :

AST_MODULE_INFO (
  "MySQL CDR Log Backend",
  AST_MODFLAG_DEFAULT,
  "MySQL CDR Backend",
  .load = load_module,
  .unload = unload_module,
  .reload = reload,
);

sitting at the bottom.  In the load_module, it starts off with :

static int load_module(void) {
  int   res;
  res = 0;
  ast_log(LOG_ERROR,"test: debug message\n");

which leads me to believe that my load_module function isn't being 
called.  Truth be told (and I think this is where the culprit is), I 
think it is the way I am compiling my module.  Everything I have seen 
states that I should be compiling the module inside of the asterisk 
source tree, but I'd rather just compile it against the binary RPM's (if 
possible).  So I ask, is it possible to compile the module outside of 
the source tree?  My compilation lines are :

gcc -fPIC -I/usr/include -c cdr_mysql.c -o cdr_mysql.o
ld -L/usr/lib/mysql/ -shared -lcrypt -lpthread -lmysqlclient -E -rpath 
/usr/lib/mysql/ -o cdr_mysql.so cdr_mysql.o

Can anyone offer any advice?
