Error installing ns-allinone-3.37 on Ubuntu

I'm installing ns-3.37 in my Unbuntu 22.04 on Macbook, after running

./build.py --enable-examples --enable-tests

I get error message

I have installed all the required surroundings like below

$ sudo apt install build-essential autoconf automake libxmu-dev g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev  libxml2 libxml2-dev libc6-dev libc6-dev-i386 libclang-dev llvm-dev automake python3-pip libxml2 libxml2-dev libboost-all-dev

Would someone please tell me how to fix this problem?

Solution

The problem is that cmake installed on your system has version 3.x.0-rc4. This is a bug in the ./ns3 script that it cannot parse 0-rc4 parse properly and expects it to be an integer.

You can try to run apt-get update && apt-get install cmake and see if the version of cmake changes.

If nothing else, you can comment out or remove these lines in ./ns3:

    if parse_version(version) < parse_version("3.10.0"):
        print("Error:  CMake found at %s but version %s is older than 3.10" % (cmake, version))
        exit(1)

Then you can report the bug to ns-3 developers as it is actually a bug in the ./ns3 script they maintain.
