PATCHINGDETAILS:

HerearetheproblemsI'vefixedwithns-2.27(firsttwoareinmac/channel.cc):

1.WirelessChannel::sendUpcontainsanelsestructurewithlist-basedimprovements.Irevertedthatelsestructurebacktowhatitwasin2.26.Withoutthismodification,PHENOMpacketswillnevergetreceived.

2.WirelessChannel::updateNodesListcontainsacalltosortLists().Iremovedthatcallinordertofixasegmentationfault.

3.Themakefilesns-2.27/indep-utils/cmu-scen-gen/setdest/Makefile,ns-2.27/indep-utils/webtrace-conv/conv/Makefile,andns-2.27/indep-utils/webtrace-conv/dec/Makefile,

neededtobemodifiedinordertofixabuginISI'sdistribution.Thebugcausedacompile-timeerrorthatlookedlikethis:

g++-c-Dstand_alone-DSTL_NAMESPACE=@[email protected]../../../config.h:54,fromsetdest.h:5,fromsetdest.cc:57:../../../autoconf.h:85:Error:namespace`CPP_NAMESPACE'undeclaredsetdest.cc:71:1:warning:"INFINITY"redefinedInfileincludedfrom/usr/include/math.h:40,fromsetdest.cc:43:/usr/include/bits/mathdef.h:35:1:warning:thisisthelocationofthepreviousdefinitionmake[1]:***[setdest.o]Error1make[1]:Leavingdirectory`/home/iandow/netsim/ns-allinone-2.27/ns-2.27/indep-utils/cmu-scen-gen/setdest'make[1]:Enteringdirectory`/home/iandow/netsim/ns-allinone-2.27/ns-2.27/indep-utils/webtrace-conv/dec'

Tofixthebug,editns-2.27/indep-utils/cmu-scen-gen/setdest/Makefileandchangethisline:DEFINE=-Dstand_alone-DSTL_NAMESPACE=@STL_NAMESPACE@tothisline:DEFINE=-Dstand_alone-DSTL_NAMESPACE=@STL_NAMESPACE@-DCPP_NAMESPACE=std

Intheothertwomakefiles,append-DCPP_NAMESPACE=stdtoCFLAGS.

IdiscoveredthatfixbysearchingtheNSnewsdatabase[2]for"CPP_NAMESPACE".
