[ns] Re: known compile error in ns-2.27

[Arne Lie]

Hi,

I have just found a manual solution that works for me. I searched the ns-2
archive at www.isi.edu/nsnam/htdig/search.html (thanks to Victor Gonçalves
Alves) and found pointers to http://nrlsensorsim.pf.itd.nrl.navy.mil/ and
the patch file
http://nrlsensorsim.pf.itd.nrl.navy.mil/nrlsensorsim-2.27.tgz. Well, I
downloaded and read the documentation. It said that the patch had to be
applied on a clean system where ./install had not been activated yet.
Well, my system has been used some while, so... OK, so I looked carefully
through the patchfile to see what it would do to the Makefiles of
interest. Then I saw that it suggested to add
-DCPP_NAMESPACE=std
instead of the already suggested at ns-2 error page
-DCPP_NAMEspace=@CPP_NAMESPACE@
in the Makefile.in files. OK, so I tried, but still I saw the same error
message. Since I do not know how the main Makefile is using the
Makefile.in file, I tried a final crude solution: to edit the Makefiles
directly. And, now it will compile! I just hope that the compilation is
fine, I do not know what these last programs are doing. So, the solution
is

In ./indep-utils/cmu-scen-gen/setdest/Makefile, modify the DEFINE to
DEFINE = -Dstand_alone -DSTL_NAMESPACE=@STL_NAMESPACE@ -DCPP_NAMESPACE=std

In ./indep-utils/webtrace-conv/nlanr/Makefile, modify the CFLAGS to
CFLAGS =  -DSTL_NAMESPACE=@STL_NAMESPACE@ -DCPP_NAMESPACE=std

In ./indep-utils/webtrace-conv/dec/Makefile, modify the CFLAGS to
CFLAGS =  -DSTL_NAMESPACE=@STL_NAMESPACE@ -DCPP_NAMESPACE=std


best regards

Arne
