[OpenSIPS-Users] Building Presences and PUA for OpenSIPS 1.6.1

[Steven C. Blair]

One more thing. My config is quit old and still references uri_db. This module did not build and does not seem to exist in the source for 1.6.1-notls. I didn't see any mention of this in any changelog. Has this module been moved or changed into another?

Thanks,Steve

Hello Steven,

There are no problems building the modules of the 1.6.1 release,
however the difficulty you describe is already known. To date no
correction has been made to the defective build configuration.

Take a look at the Makefile of a number of modules using libxml,
for example the one in modules/presence specifies:

DEFS+=-I$(SYSBASE)/include/libxml2 -I$(LOCALBASE)/include/libxml2 \
      -I$(LOCALBASE)/include
LIBS=-L$(SYSBASE)/include/lib  -L$(LOCALBASE)/lib -lxml2

...but hardcoding such values into the build configuration is risky
and often leads to runtime security problems or build failures like
the one you're describing. Do this instead:

DEFS+=`/pfx/bin/pkg-config --cflags-only-I libxml-2.0`
LIBS=`/pfx/bin/pkg-config --libs libxml-2.0`

The 'pfx' is the path root in which you have libxml. In
'/pfx/lib/pkgconfig' you'll find 'libxml-2.0.pc' which can
be queried with the program 'pkg-config'.

Testing this on my system I see:

  $ /pfx/bin/pkg-config --cflags-only-I libxml-2.0
  -I/pfx/include/libxml2 -I/pfx/include
  $ /pfx/bin/pkg-config --libs libxml-2.0
  -R/pfx/lib -L/pfx/lib -lxml2 -lz -liconv -lm -lsocket -lnsl

...and that is what the OpenSIPS build configuration should be
using. By the way, this defect is not specific to the build
configuration of the presence modules. It is in others as well.
Good luck.

Regards,
Brian
