Not sure about that - I can only find Mudlet 2.1-2 for Raspbian in the output from:

Code: Select all

stephen@Ripley:~/src/mudlet-dev/Mudlet/mudlet-code$ curl -s http://archive.raspbian.org/raspbian/dists/jessie/main/binary-armhf/Packages.xz | xz -d | grep -A 1 '^Package:' |cut -d ' ' -f 2| grep -A 1 mudlet
mudlet
1:2.1-2
i.e. from the "Jessie" (oldstable) distribution; I am not seeing anything from the "Stretch" (stable), "Buster" (testing) or "Sid" (unstable) versions... On the other hand Debian testing does indeed carry Mudlet 3.1 (see https://packages.debian.org/sid/mudlet ).

OTOH that is likely to be shortly disappearing according to my Inbox as I am getting a notification: "mudlet is marked for autoremoval from testing" with the following message body:

mudlet 1:3.7.1-1 is marked for autoremoval from testing on 2018-09-22

It is affected by these RC bugs:
907159: mudlet: FTBFS in buster/sid (invalid use of incomplete type 'class QTabBar')

According to https://packages.debian.org/search?keywords=mudlet is Mudlet only in "Jessie (oldstable)" available for armhf at all. And there it's version 2.1 as SlySven suggests above. http://buildd.raspbian.org/status/packa ... ch-staging also suggests that it's not being built for armhf.

I tried my hand for a while now at compiling Mudlet for raspi, but I had no luck yet as the precompiled versions of Qt for Raspbian/Debian armhf use OpenGL ES instead of OpenGL (without ES). And that is not compatible with Mudlet. I didn't try to compile Qt myself yet to get it to use the full OpenGL.

TBH I am not sure that you can get the full OpenGL library built on the display hardware that is present in the videocore of any of the RPis - it is the sort of hardware that is going to be targeted by the ES variant. In order to support the lower spec'ed hardware (compared to a Desktop PC) we will really need to update the glwidget class to move away from the simple and fairly straightforward direct OpenGL functions that are a feature of 1.0/1.5/2.0 (and many on-line tutorials) and start using the indirect stuff that 3.0 (and later) OpenGL or OpenGL ES mandates.

Anyone know how to write a shader - SlySven doesn't... :shock:
