Newbie question regarding multimediawidgets missing issue

[MichRX7]

This is what is so frustrating. I have Python3, if I enter "python3 --version" it tells me I have Python 3.7.3

That is old Python2. Linux ships with python command pointing to Python2, but python3 command to point to Python3.

I don't think you have to tell Qt Creator anything about Python. As I said, what you need to look at is what version of gdb you have/it is using. The implication of the error message is that it is the gdb which is not good.

See also e.g. http://sourceware.org/gdb/current/onlinedocs/gdb/Python.html. It says:

This feature is available only if GDB was configured using --with-python.

Maybe your gdb is not built with that.

I'm afraid this is all outside my experience.

So, how do I get the gdb "which is good"?

[MichRX7]

Do I download this Linux file from here, edit the versions inside and run it somehow to make a working gdb?

I'd really like to actually build something inside QT Creator, lol...

One way to check it gdb was built with python is to call ldd $(which gdb). It will list the libraries gdb is linked against and you should have the python library if gdb was built against it including the version of Python.

@MichRX7 What Linux distribution and version do you actually use?

Debian GNU/Linux 10 (buster)
Running it on an old Dell Latitude D630 I found sitting in a box. :)

[SGaist]

Which version of gdb do you have ? I thought that the buster current version was built with python support.

gdb --version
GNU gdb (Debian 8.2.1-2+b3) 8.2.1

@MichRX7 This site tells me that GDB on that Debian version uses Python: https://packages.debian.org/buster/gdb
Are you sure you installed the default gdb package?

[MichRX7]

@jsulm Unsure, on that box I installed QT and Creator direct from the download page. Unless I did something trying to follow the directions somewhere on how to cross-compile on a raspberry pi (unsuccessfully follow that is) I do not know.
