[MAC][Linux?]I published an SFML applet: ToneBoards

[kipbits]

FWIW I'm looking into Elementary OS.
wikipedia
and it looks like they have an AppCenter

Update: I'm thinking I'll go with Gnome after all. I still have not found any good way to distribute paid linux apps; I was kind of wondering if Gnome-Software had any plans for this. Will post when i get information.

I've been very sidetracked by other projects, so I version 2 is still on the back burner. I'm still running sfml-2.3.2 on my mac. Good news though, I bought a new dev machine, so hopefully will have some time and get back here in the not to distant future.

Having second thoughts about getting too much into Gnome as a platform. GPL/LGPL is kind of alot to wrap your head around. I have alot of concerns about how i might be limited going with a platform like this. I'm trying to make this worth my time, you know what i mean (;P)?

I noticed some of the libraries SFML uses are LGPL, GPL. from what i understand LGPL is not necessarily a problem, but GPL makes me worry.
Will I need to release all my source-code?

Anyway wondering if anyone knows of a platform with a more straight-forward and Free mission statement, not this comrade BS, you know what i mean (;P)?

I posted a question on law.stackexchange.

You don't need to worry.

I really wonder which ones are GPL.

External libraries used by SFML
-------------------------------

* OpenAL-Soft is under the LGPL license
* libjpeg is public domain
* stb_image and stb_image_write are public domain
* freetype is under the FreeType license or the GPL license
* libogg is under the BSD license
* libvorbis is under the BSD license
* libflac is under the BSD license


Anyway I was planning to read through the GPL/LGPL when I get the time to really sit and process what it means. Its been kind of hard to find definitive information about it. A lot of disagreement from what i've seen.

Thanks, I know what the license page contains... And my point is that there's no SFML dependency that forces the use of GPL. Those that have GPL also have other (more permissive) licenses available. SFML always ensures that you only need to worry about its own license, all its dependencies are chosen to be compatible with it.

[kipbits]

I suppose an original developer can relicense there software(freetype), but why would they still give the GPL option? why not simply copyfree? is freetype built on gpl parts? if so wouldn't that make gpl forever, and all work linking to it also gpl?

Maybe i'm missing something?

[Laurent]

You should definitely read the FreeType license if you want accurate information.

As far as I know, there are two cases:

1. Dual licensing. Because some may prefer GPL, and some others may prefer something else. Don't ask me why, I'm not a GPL expert. But according to FreeType license page, GPL v2 has some incompatibilities, even with more permissive licenses.

2. Sometimes, libraries are under a permissive license, but some (optional) parts of it, plugins or whatever, are under a different license, because they themselves depend on other libraries, or because the contributor insisted on using that license.

FreeType seems to be in case 1. so we can choose to use it under the FTL (BSD style, very permissive) and not worry about it.

[kipbits]

Thanks for the info.

I do plan to do more research into this

[kipbits]

I think you are right about Freetype being optional GPL. The Freetype license itself is very permissive. I posted an answer to my question on law.stackexchange. I don't think any of it really applies to SFML other than to say there's nothing to worry about, but people might find it interesting...

[kipbits]

also, I'm still looking into an alternative linux/unix development platform(as apposed to ubuntu). I'm wondering if anyone has built SFML on FreeBSD or Étoilé?

looks like someone else already did this

[eXpl0it3r]

You could give Arch a try. I know a lot of developers who quite enjoy it.

I decided to publish the source for ToneBoards. I just haven't had as much time to work on it as I would have liked this past year. Perhaps someone will find it useful. Also I'm kind of thinking about letting my Apple developer account lapse. It's just another expense for me right now, and was sort of a hassle to set up. I'm becoming more interested in other ways to assure users of quality/integrity of a piece of software. I've recently discovered a makeshift alternative to apple developer certificates(i think). I mean what is the point of code signing when you can just compare digests using openSSL?

Below are some Github links, and I'm also posting digests and filesizes. I think this should provide a way for users to gain 99% of the assurances provided by the Appstore(with a couple added steps on the user's part).
