Wireshark seems to need Python 3.4 or better, and I have Python 3.6 installed and am using the software collection (scl enable rh-python36 bash) but cmake 3 does not want to find it. I get: [rsharpe@localhost wireshark-build]$ python -V Python 3.6.3 cmake3 ../wireshark-official ... CMake Error at /usr/share/cmake3/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find PythonInterp: Found unsuitable version "2.7.5", but required is at least "3.4" (found /usr/bin/python) Any suggestions?Either clean your build folder, or edit your CMake cache file to remove the PythonInterp entry and force a new search.It was a completely new build dir. In the end, because I imagine the Wireshark build needs a more recent version of Python, but the base platform still needs Python 2.7.5, I went with virtualenv and it seems to have worked. sudo pip3.6 install virtualenv virtualenv ./wireshark-master cd wireshark-master/ source ./bin/activate cmake3 /path/to/wireshark/source seems to work.Like Pascal said, clearing PYTHON_EXECUTABLE from your CMakeCache.txt was sufficient (you do not have to wipe the full build directory). The default /usr/bin/python interpreter is Python 2.7, but CMake will now search for python3 first and use that if it is new enough.
Why doesn't it fall back to 2.7? I didn't have Python 3.x on that VM, but the cmake step should not fail if it cannot find Python 3.x when 2.7 is acceptable. However, it kept telling me that 2.7.5 was not acceptable. -- Regards, Richard Sharpe (何以解憂?唯有杜康。--曹操)(传说杜康是酒的发明者) ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
