Errata against ns-3.24.1 release
ns-3.24.1 was released on 30 September 2015 to address the issues listed below in the ns-3.24 errata.
No further errata against the most recent ns-3.24.1 release have been posted.
Errata against ns-3.24 release
Mac OS X: Shortly after the ns-3.24 release, Xcode 7.0 was released by Apple. This framework causes build problems for ns-3. Until the problem is fixed in a new release, users who encounter problems should apply the patches and workarounds in https://www.nsnam.org/bugzilla/show_bug.cgi?id=2181. This will be fixed in a ns-3.24 maintenance release.
A workaround is to pass modified CXXFLAGS to the waf configure step; i.e. instead of configuring as:
./waf configure --enable-examples --enable-tests
instead type (all in one line):
CXXFLAGS="-Wall -Werror -Wno-potentially-evaluated-expression -Wno-unused-local-typedefs" ./waf configure --enable-examples --enable-tests
Python bindings detection: Users of ns-allinone-3.24 release posted on Sept. 15 will not be able to automatically detect pybindgen and use Python features including the Pyviz visualizer. This will be fixed in a ns-3.24 maintenance release. There are three workarounds (choose one of the below solutions):
1. Instead of
./waf configure --enable-examples --enable-tests
tell Waf explicitly how to find pybindgen with the --with-pybindgen option; e.g.
./waf configure --enable-examples --enable-tests --with-pybindgen=../pybindgen-0.17.0.post41+ngd10fa60
2. create a symbolic link to pybindgen, or rename the directory to 'pybindgen'; e.g.
cd ns-allinone-3.24 ln -s pybindgen-0.17.0.post41+ngd10fa60 pybindgen
3. patch the ns-3.24 source code with this patch: http://code.nsnam.org/ns-3.24/rev/51263c7e64bb
gcc-4.4.7 compilation on 32-bit Linux
The following error was reported for gcc-4.4 on a 32-bit Linux system:
../src/wifi/model/mac-low.cc:1665: error: integer constant is too large for ‘long’ type
this can be fixed with this patch: http://code.nsnam.org/ns-3.24/rev/05ea1489e509
