That seems... odd. Looking at the SF repo, I see a few commits per week, last one on 2018-09-01 17:08:16 - so if he sees no changes, where is he looking at?

(I actually don't see the intermediate discussion as rubbish or useless - though it is very much off-topic and can well be moved - I have a feeling it has moved somewhere which is not a cycle and maybe something good comes from that in the future. It seems to me that some misunderstandings could be cleared - and doing that isn't crazy as far as I'm concerned, as tedious as it may be to read)

Wkitty42 and Thorsten I thought commits were sent to him to build and then add to the Launchpad edge PPA. I don't know the exact process though. I would start a new topic but I'm not sure if you want me too since its the daily version and there will probably be a lot of people who will just comment that its the daily version and it can be broken. :) We already know this. I'll try and get it working again and like I said if I get the error again I'll just send it to the mailing list with the information needed to go along with it. I've done enough to confuse this thread though so if we need to talk about it further I can start a new thread.

Suggested procedure:

* talk to Saikrishna whether there's an up-to-date version he has compiled, mention that SG is being updated all the time - if he can't compile one because the compiler doesn't run through, ask him to report the compilation error to the mailing list

* if he can compile one, try to run it. If it leads to errors, report them here or on the mailing list and we'll try to take it from there

Thing is, we need a log or error message or something, otherwise this is hopeless to debug.

I just installed it from the PPA and it works. That makes a smiley face. :)

Getting back to the original topic. Apologies for interrupting those who have taken it over. ;)

A patch has been submitted to JSBSim and this is working its way through the system, Once it has been accepted into JSBSim there will be a short delay before Flightgear is synchronized with the latest JSBSim changes, at which point it will be available on the cutting edge (i.e. git or nightly) version of FG.

You should really be thanking Scot who did the work. I am only the messenger.

This JSBsim update, together with a few others, has now been pushed to the Flightgear git repository.

It is /fdm/jsbsim/propulsion/engine/AFR.
I have just done a quick test on the C172 and it varies as expected when I play with the mixture control.

Note that you will need the latest development version of FG. I compile my own using the git sources. You should also be able to download a compiled version from http://wiki.flightgear.org/FlightGear_build_server.
