lr-mame2016 fails to build on Ubuntu 21.04

@johnodon said in lr-mame2016 fails to build on Ubuntu 21.04:

AttributeError: 'array.array' object has no attribute 'tostring'

this might be related https://github.com/python-intelhex/intelhex/pull/46

what version of python have you install now? it seems like this should only be an issue with python 3.9 and up. you might want to check your versions

@dankcushions

pi@elitedesk:~$ ls /usr/bin/python*
/usr/bin/python2  /usr/bin/python2.7  /usr/bin/python3  /usr/bin/python3.9

@johnodon makes sense. i guess it's running the install via 3.9 and hitting the issue. i guess you could uninstall 3.9? or try and work out how to update intelhex, although i'm out of my depth with python-related stuff so who knows.

any particular reason you're trying to run 2015/16? any x86_64 machine might as well run current lr-mame, or indeed mame standalone.

@dankcushions

Not sure if it is still valid but I was going to use Roslof's emulator list to build my arcade collection:

Thoughts? I'm wondering if this really doesn't even apply to me since I an on x64 (list is based on Pi4).

@johnodon yeah on x86 you should just use standalone mame (you could use the lr- version but i’m not sure what kind of state it is in these days). mame only gets better - the only reason we use these older versions on pis is because we often don’t have the headroom to run later/latest. as soon as you have a modest x86 setup, there’s no reason to use them.

johnodon

@dankcushions Thanks. That is the direction I will go in.

FYI...MAME installer script is boogered on Ubuntu 21.04. qt5-default is a dependency but it has been obsoleted. I don't know if it will have any ill effects but I was able to at least get around it using the 'fake-out' method in this post: https://askubuntu.com/questions/1335184/qt5-default-not-in-ubuntu-21-04

If you are installing some package from third-party which requires qt5-default package on Ubuntu 21.04 (or newer), then you can create fake package by using commands below:

sudo apt-get update
sudo apt-get install equivs

cd ~/Downloads
cat <<EOF > qt5-default-control
Package: qt5-default
Source: qtbase-opensource-src
Version: 5.99.99+fake-13ubuntu37

You can replace the qt5-default dependency with qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools. Similar to https://github.com/RetroPie/RetroPie-Setup/commit/fbfcc0c9847b6b3a227a4cbb41185bd9ac1849b4.

@mitu I'm pretty sure I tried that first but still got the qt5-default error. I'm compiling now. Once done I'll look at my bash history an make sure that is exactly what I tried.

johnodon

I ran this just prior to trying to install MAME...

sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools

...but got the same error. In fact, you can see those packages are up to date if I try to install them again:

pi@elitedesk:~$ sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools
Reading package lists... Done

qtchooser is already the newest version (66-2build1).
qt5-qmake is already the newest version (5.15.2+dfsg-5ubuntu1).
qtbase5-dev is already the newest version (5.15.2+dfsg-5ubuntu1).
qtbase5-dev-tools is already the newest version (5.15.2+dfsg-5ubuntu1).

I'll build another 21.04 Server box to confirm.

I'd like to piggyback here just a bit, and hopefully not offtopic just to share my experience for whatever it's worth.

I've tried many times to get mame installed on my custom built PC from 2012 and failed numerous ways. The PC is AMD processor based and uses a Radeon 7770 GPU, and I can install lr-mame20003 and lr-mame2010 with no problems whatsoever. But when I've tried lr-mame2016, lr-mame, or even mame, I always end up with errors similar to the above and a failure to install.

 fatal: No names found, cannot describe anything.

I've mostly stuck to Ubuntu 20.04, but once tried 21.04 and ran into the same thing @johnodon mentioned about the qt5 dependency. So today I got hold of a Dell Optiplex 3070 to test. I was able to install lr-mame onUbuntu 20.04.2 on the first attempt. This is Intel CPU based with integrated graphics.

I suspected and am now increasingly convinced that either my AMD CPU or my old Radeon GPU has something to do with being unable to install on my old PC. Unfortunately the logs and error messages don't provide enough clues to fix it in my experience. So when I get around to doing an arcade cabinet build, I will be looking for an Intel based system.

I wonder if there is anyone who can say they have installed newer mame cores on Ubuntu using AMD processors or AMD / Radeon GPUs.
