"error: expected unqualified-id before numeric constant" after linking an external library

[Infiel]

Hello,

I was trying to port a module from ns2 to ns3 (cause earlier I was working on NS2). But that module was written with the use of ITPP libraries, so, to make a taks easier (especially the initial step). I modify the wscript with lines:

    conf.env.append_value("CXXFLAGS", ["-Wall", "-g", "-DNDEBUG", "-pipe", "-O2"])
    conf.env.append_value("LINKFLAGS", "-litpp")

flags were obtained by:
     pkg-config --cflags itpp
   pkg-config --libs itpp

After that I have added an include declaration:

#include <itpp/itbase.h>

and nothing more. During compilation, I have an error:

In file included from /usr/include/itpp/base/gf2mat.h:48,
                 from /usr/include/itpp/itbase.h:114,
                 from ../src/lte/helper/geometry-helper.cc:15:

=================================

What that means and how do I can overcame this problem? Is that a name conflict with some typdef od constant definitions from current NS3 code ?

By "the wscript" are you referring to the wscript inside src and not inside the modules?

Okay, I have figured it out!!!. In the file in which I had included itpp libraries, a had eps variable defined (#define eps 0.0000000001). Yeach, I love c++.

Here is the link:
http://www.nsnam.org/wiki/index.php/HOWTO_use_ns-3_with_other_libraries

I have just used code in the second box (conf.env.appen_value() ...) when I have added a proper flags (obtained by pkg-config).
