[Flightgear-devel] portability of simgear
Hi, I recently uploaded version 2.10 of simgear to Debian, but see it fail on many platforms. I do not currently have the time to investigate. If somebody does, please see here: https://buildd.debian.org/status/package.php?p=simgear More importantly: is there any long-term commitment about what platforms simgear and flightgear are actively supported on? I'm inclined to focus on fewer architectures, but make those packages better. (After all, very few people have access to a powerpc, let alone powerpc with decent 3D acceleration.)

Re: [Flightgear-devel] portability of simgear
Hi Markus, I'm glad to see you are looking at simgear's update for Debian. However we are ready to release simgear 2.12 in next days, so I would suggest you to spend your time with simgear 2.12 instead of (soon outdated) 2.10 We have a lot of lacks for many years about package diffusion for Ubuntu/Debian ( version 2.6 is still diffused while we released 2.8 one year ago and 2.10 6 months ago) How can I help you maintaining this diffusion in order to always diffuse the latest stable version ? About platform's support: looking at our lacks I would suggest to focus on main platforms for now. If we are able to provide the 2.12 version for amd64 and i386 we are feeding 95% (maybe more) of our users. Linux users are lucky to have a package manager (compared to Windows users who need to download the package by searching on the Web) so it's important to keep the diffused package up-to-date in order to give a better experience to our users.

However we are ready to release simgear 2.12 in next days, so I would suggest you to spend your time with simgear 2.12 instead of (soon outdated) 2.10 I'm aware of the upcoming release, eagerly awaiting it, and have already started packing. Given the decision to slip the 2.12 release, I decided to move on with 2.10 rather than wait another month, though. I'll certainly focus on 2.12 as soon as it's released. I don't think it changes a lot WRT portability, though. Do you? We have a lot of lacks for many years about package diffusion for Ubuntu/Debian ( version 2.6 is still diffused while we released 2.8 one year ago and 2.10 6 months ago) How can I help you maintaining this diffusion in order to always diffuse the latest stable version ? There are a few areas where I could need help or need to feed patches back. You could take a look at the patches currently applied to 2.10. Another issue I run into was the mixture of GPL vs LGPL in simgear. I personally don't care much, really. As a packager, though, I'd appreciate if at least all the files that are under copyright by the flightgear authors were released under the same license. (IANAL, but given there are GPL files in simgear, my understanding is that the entire library can only be used under the terms of the (more restrictive) GPL, rather than LGPL). Another thing I'm not sure about is the versioning policy. My understanding is that minor versions are not compatible between each other (i.e. 2.10 vs 2.12). How about the patch version? Is a (hypothetical) simgear 2.10.1 compatible with flightgear 2.10.0? Or vice versa? (FWIW, the former packager (Ove) took the pessimistic approach and I didn't change that.). About platform's support: looking at our lacks I would suggest to focus on main platforms for now. If we are able to provide the 2.12 version for amd64 and i386 we are feeding 95% (maybe more) of our users. According to Debian's popularity contest, we're closer to 98.4% of the participating systems being i386/amd64 (including the kfreebsd ones). And given that the next best two, i.e. ARM (arm, armel, armhf, together 0.8%) and PowerPC (0.5%) can hardly be considered gaming platforms, we're reasonably close to 100%. However, I like diversity and given the successes on sparc and mipsel give me hope of an easy fix... Linux users are lucky to have a package manager (compared to Windows users who need to download the package by searching on the Web) so it's important to keep the diffused package up-to-date in order to give a better experience to our users.

You could take a look at the patches currently applied to 2.10. I was under the impression all patches had been up streamed - the correct process here is to file merge requests and email here (since unfortunately Gitorious merge requests don't notify people) Or you can simply email diffs here / to me, but either way the patches can be applied. Another issue I run into was the mixture of GPL vs LGPL in simgear. I personally don't care much, really. As a packager, though, I'd appreciate if at least all the files that are under copyright by the flightgear authors were released under the same license. (IANAL, but given there are GPL files in simgear, my understanding is that the entire library can only be used under the terms of the (more restrictive) GPL, rather than LGPL). This is a bug in our code. We have files with missing licenses, files which were moved between FG and SG, and files which were contributed public domain. However 'the license' for SimGear is LGPL and for FlightGear, GPL version 2 (or later at discretion, but we don't require version 3). Patches to clean up the situation are welcome. Given the license file and docs have always been clear which license each project is under, I think it is safe to consider file-level discrepancies as bugs and standardise. Another thing I'm not sure about is the versioning policy. My understanding is that minor versions are not compatible between each other (i.e. 2.10 vs 2.12). How about the patch version? Is a (hypothetical) simgear 2.10.1 compatible with flightgear 2.10.0? Or vice versa? (FWIW, the former packager (Ove) took the pessimistic approach and I didn't change that.). We very rarely do patch releases, but thanks to Jenkins is at least possible. Patch releases should be compatible I would hope, eg when I made the 2.10.1 patch of FG it still used SG 2.10.0 Minor versions are incompatible.

However, I like diversity and given the successes on sparc and mipsel give me hope of an easy fix... Personally I wouldn't spend your time, far more useful would be to get ARM working so we can run parts of the stack on Pis, Pandaboards and so on. This would be materially useful for various add-on functions, especially the canvas and fgcom. (I spend an increasing amount of my work time on OpenGL on ARM platforms, they have plenty of power to run graphics, depending on which GPU is on the SoC) Regards, James https://lists.sourceforge.net/lists/listinfo/flightgear-devel -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
