[Asterisk-Dev] Question about compiling a module for Asterisk with CPP stuff

[Leo Moll]

Hi Everybody!

I'm writing an extension module for my asterisk but I have a problem 
that I can't figure out. The compilation of the project makes no 
problem, the .so file is created correctly but the module is not loaded 
by the Asterisk.

In the log file I got the following error:

Feb  4 01:36:39 WARNING[13395]: 
/usr/lib/asterisk/modules/app_say_pattern.so: undefined symbol: _Znaj
Feb  4 01:36:39 WARNING[13395]: Loading module app_say_pattern.so failed!

The module contains some source files written in CPP but I have used 
only straight CPP without STL or similar stuff.

Here you can see an excerpt from my Makefile:

CFLAGS+=-ggdb
LDFLAGS+=-lstdc++

all: nlsLib app_say_pattern.so

nlsLib: nlsEngine.o nlsUtils.o nlsParser.o
    $(CC) $(CFLAGS) $(LDFLAGS) nlsEngine.o nlsUtils.o nlsParser.o -o nlsTest

CFLAGS+=-fPIC -I$(ASTERISKINC) -DAST_CONFIG_DIR=\"$(AST_CONFIG_DIR)\"

app_say_pattern.so: nlsEngine.o nlsParser.o nlsUtils.o app_say_pattern.o
    $(CC) -shared -Xlinker -x -o $@ nlsEngine.o nlsUtils.o app_say_pattern.o



Does anyone here have an idea what I'm doing wrong? Any help would be 
greatly appreciated.

Thank you in advance!
