Errata against ns-3.29 release
The following issues have been identified since the ns-3.29 release, and will be addressed in a future ns-3.29.1 release update.
MacOs Clang 10 compatibility: Shortly after the ns-3.29 release, a MacOs Clang compiler update was issued; this causes the ns-3 build to fail as follows:
./ns3/make-event.h:665:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
typedef void (*F)(U1, U2, U3);
^
./ns3/make-event.h:699:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
typedef void (*F)(U1, U2, U3, U4);
^
./ns3/make-event.h:633:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
typedef void (*F)(U1, U2);
^
./ns3/make-event.h:665:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
typedef void (*F)(U1, U2, U3);
^
4 errors generated.
This can be worked around by passing the '--disable-werror' flag to Waf configuration step; e.g.:
./waf configure --disable-werror --enable-examples --enable-tests
API scan for ns-allinone-3.29: The version of pybindgen associated with ns-allinone-3.29 is incorrect, and the bindings toolchain will not install correctly. An example error output is:
from pybindgen.castxmlparser import ModuleParser, PygenClassifier, PygenSection, WrapperWarning, find_declaration_from_name
ImportError: No module named castxmlparser
One workaround is replace the 'bakeconf.xml' with the version corresponding to this changeset:
Python 3.7 and API scanning toolchain: ArchLinux has started to distribute Python 3.7, but there are issues with compatibility of the toolchain.
There is no present workaround other than piecing together the hints found in the above bug report.
