[asterisk-users] Dynamic loading changed in asterisk 1.4

[Mosiuoa Tsietsi]

Thanks Kevin,

After looking at the skeleton application, I inserted the line

*AST_MODULE_INFO_STANDARD(ASTERISK_GPL_KEY,"My Prepaid Application");*

To the end of the application. I also changed all references to
pbx_exec(chan,app,data) to include three parameters instead of four (I guess
the APIs have changed, the last parameter was an int).

I no longer get the original message about failure to load, however, I do
get a new message;

*asterisk: symbol lookup error: /usr/lib/asterisk/modules/app_prepaid.so:
undefined symbol: mysql_init *

Just so you know, I have res_config_mysql.so loaded already and I thought
this would provide this symbol. I have played around with my Makefile in
case it was a linking issue but cant seem to get it right. I enabled the
NOISY_BUILD var in the Makefile in the asterisk root directory, so the
actual gcc build command is displayed, which is:

*gcc -o app_prepaid.o -c app_prepaid.c -pthread
-I/opt/bristuff-0.4.0-RC3c/asterisk-1.4.21.2/include  -pipe -Wall
-Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -g3 -include
/opt/bristuff-0.4.0-RC3c/asterisk-1.4.21.2/include/asterisk/autoconfig.h
-march=i686  -O6 -fPIC -DAST_MODULE=\"app_prepaid\"   -MD -MT app_prepaid.o
-MF .app_prepaid.o.d -MP*

Any ideas? Thanks,

Mos
