Explanations for configure options?

Anders Gustafsson

Are they documented anywhere? Some things are pretty self-explanatory, ie things like --disable-avahi but some are just greek to me.

Saen Acro

Long time ago I also ask same question,
no answers.

Anders Gustafsson

OK. Perhaps better luck this time? :)

Robert Cameron

Most (all) options are exposed through './configure --help'. Is there a specific option you don't understand, because I believe they are all rather self-explanatory.

not so informative
example
what isEnable android, what it do?

Robert Cameron

It does exactly as it sounds: sets up the build for a binary that can run on Android (arm-linux-androideabi-).

Are there other options that need explanation?

Anders Gustafsson

OK. That is a start :) Why not put this in the wiki? I could do that, but I do not seem to have the rights to create a page there.

Anyway, what I was looking for was to skip stuff that I have no need or use for. This means that there would be less libraries to download and install and less risc for problems. In my case, I just use DVB-T and DVB-C, so I do not need SAT, nor iptv.

I also assume that I do not need Avahi as I do not use Apple devices and Avahi, however useful, is quite a problematic protocol.

So, if I would be able to create a wikipage, then I could at least start documenting.

Robert Cameron

If you're curious and want to investigate, check out the configure script in the github repo. If there's an option that confuses you, look at the commit notes for when it was added and the modifications done to understand what it does.

Anders Gustafsson

Great tip! Let me have a look at it and if I have the time do some documentation!

I've added you to the Wiki editors group, feel free to help with the documentation.

Anders Gustafsson

Thanks! Appreciated!

Аt least 10 words for the option,
what it do, and why is needed.

Does this look like a start? I will do my best, but have quite a lot on my plate at the moment, but the more we can help the developers, the more time they have to make the code even greater!

Nice! But line break when using h1|2|3. so the rest isn't bold.

Yes. I have not done much Wiki work lately. Used to be pretty active on wikipedia. I did start looking at the configure history, but much of it assumes that you are cery well-versed in multimedia programming, but I will do my best in the hope that others will correct any errors I make.

OK. Been a while. I have now added all the config options in 4.3, with those explanations that I could find. Feel free to add or just tell me and I will add explanations. This is my humble way of giving back to this great project.
