[OpenSIPS-Users] debian packaging and compiler options

[Bogdan-Andrei Iancu]

Hi Kennard,

I personally use the the defaults from debian/rules .  If you want to 
take full advantage of all special flags that are pushed by Makefile, 
you can try to prevent the debian/rules to set a the flags by removing 
the lines:

CFLAGS = -Wall -g

ifneq (,$(findstring noopt,$(DEB_BUILD_OPTIONS)))
        CFLAGS += -O0
else
    CFLAGS += -O2
endif


By doing this, the CFLAGS env var will be empty and the Makefile will 
set the flags by itself.

Regards,
Bogdan
