Hi,
I am writing a script to create custom night-builds of wireshark 1.2.0
including dissectors for a set of idls.
My script follows wireshark's idl2wrs guide [1] and works flawlessly for a
single IDL. However, building multiple idl-dissectors leads to "multiple
definition" errors fro symbols `version', `plugin_register' and
`plugin_reg_handoff'. (See the end of the e--mail for an error-sample)
It seems that the symbol clash is cause because idl2wrs is generating code
sections like the following for _each_ dissector:
#ifndef ENABLE_STATIC
G_MODULE_EXPORT const gchar version[] = "0.0.1";
#endif
#ifndef ENABLE_STATIC
G_MODULE_EXPORT void
plugin_register(void)
{
....
}
G_MODULE_EXPORT void
plugin_reg_handoff(void){
...
}
#endif
Is idl2wrs to blame or am I doing something wrong? In case it is, can anyone
suggest a workaround?
Thanks in advance,
Alfonso Acosta

Error example.
When generating and building the following dissectors:
packet-tkcomcorbaapplication-idl.c packet-tkcomcorbaguiinstallation-idl.c
packet-tkcomcorbaguiloginterest-idl.c
packet-tkcomcorbagui-idl.c packet-tkcomcorbaguiinterest-idl.c
packet-tkcomcorbaprocesslist-idl.c
I get the following building errors:
