[Ns-developers] ns-3-allinone and NSC

[Gustavo Carneiro]

Looking more closely at ns-3-allinone, which was kind of dormant, I realize
there is an issue left unsolved regarding integration with NSC.

Currently NSC is built from within the ns-3 wscript file.  I propose to
build NSC only from within the allinone build script, exclusively.

In addition, currently the ns-3 wscript creates symbolic links to the NSC
libXXX.so files into the toplevel ns-3 build dir.  I think this was meant to
allow dlopen in NscTcpL4Protocol::SetNscLibrary to be able to find the lib.
But looking at the dlopen man page it says that LD_LIBRARY_PATH can also be
used to specify a search path for dlopen.  In that case, I would like to
remove the symbolic links hacks and instead add the relevant NSC subdirs to
the LD_LIBRARY_PATH for waf check/--run/--regression/--shell.  That should
take care of the problem more elegantly.

Any objections?
