Fail to build with Sphinx 7.2
Hello,
I have a bug against the Debian package reporting that ns-3 fails to build with the latest release of Sphinx. The Debian bug is https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1042642 and an extract of the failed build logs follows. I tried to grep a bit to see how to fix it, but I don't have the beginning of an idea.
Could you please help me?
Thanks, Mt
