SFML Mac Portability

[Bocaj]

I was reading the tutorial to install SFML 2.0, and it said that it is necessary to have X11 installed on your computer in order to develop SFML.  I heard that in the next release of OS X, X11 will be removed.  Does this mean that all Mac users who have versions after Lion will have to install XQuartz before being able to open SFML applications?  Or, because they are just using SFML programs, not developing them, they don't need XQuartz to run SFML?

[Hiura]

I can't tell yet. We'll see when 10.8 comes out if the removal of X11 is only a rumor or not. Then I'll think of a solution.

SFML only use freetype from X11. Maybe I'll also provide a freetype framework like the sndfile framework.

[Bocaj]

OK, so if X11 is removed in OS X Mountain Lion, it is still possible that the downloader of the application will not have to download anything besides the .app package?

[Hiura]

As I said I don't know yet. freetype will probably - but not certainly - be shipped with SFML. We'll figure out what to do later when 10.8 is released.

What apple is shipping as X11 is actually a repackaging of the open-source (though mostly developed by apple engineers) XQuartz.

Edit:

I should really read these things twice..
Anyways, I'm not sure if you needed to install X11 in the past in order to run SFML apps since I installed it by default, but if so, then the user would (once, identical to how you install java on 10.7) get a one-click install via software update. It's quick and painless

Should be the same as with X11, so if you didn't need to install that in the past to run SFML apps, then you shouldn't have to install XQuartz.

Also, vanilla SFML 2 works just fine on 10.8

Yes, that's why I'm not 100% sure I'll make a package for freetype.

Good to hear! 
One quick question : did you upgrade from 10.7 to install 10.8 or did you make a fresh installation ?
If X11/XQuartz is no longer shipped by Apple but you did an upgrade then you might have kept freetype library from Lion. Maybe.

[capz]

I did indeed upgrade. I'll do a clean install for testing purposes later today, and build SFML on that.

Will report back asap

Edit: made this a separate post as to trigger the topic reply notification

So I've done a 100% clean install inside of VMWare (which is allowed now, so thanks apple!) and the results are in!

When you attempt to run an SFML 2.0 app, you are indeed presented with an option to install XQuartz.
Clicking it will open a browser, pointing at xquartz.macosforge.com, from which you'll have to download the disk image containing the XQuartz installer. So not a one-click as I thought before.

Everything works as expected after installing XQuartz though.

As for compiling SFML from source:
XQuartz includes a TON of libs, including freetype 2.4.9 + patches. More specifically:

* freetype 2.4.9
      * CVE-2012-1126
      * CVE-2012-1127
      * CVE-2012-1128
      * CVE-2012-1129
      * CVE-2012-1130
      * CVE-2012-1131
      * CVE-2012-1132
      * CVE-2012-1133
      * CVE-2012-1134
      * CVE-2012-1135
      * CVE-2012-1136
      * CVE-2012-1137
      * CVE-2012-1138
      * CVE-2012-1139
      * CVE-2012-1140
      * CVE-2012-1141
      * CVE-2012-1142
      * CVE-2012-1143
      * CVE-2012-1144

Configuring & Compiling SFML from source works as expected from that point onward. Kind of; the make install only worked properly when CMAKE_OSX_DEPLOYMENT_TARGET was set manually (I set it to 10.8, was blank initially)

So the freetype situation is a non-issue

For me though.. I was hoping to get an SFML project into the app store, but now I'm not so sure if that will be possible with the dependency on an XQuartz install. Might need to review the submission guidelines

[Bocaj]

Would it be possible to ship freetype with SFML so the user doesn't have to download XQuartz to run it?  XQuartz includes a lot, but SFML only needs freetype, right?

[Hiura]

Great!

Is the user still prompted to install XQuartz if you copied freetype library to your application bundle ? (If you don't have time to test this I'll test it later when 10.8 is officially released.)

Yes, SFML only need freetype from X11/XQuartz. However, I prefer not providing this extra framework because then I should keep SFML version of freetype up-to-date which is already done by XQuartz. So in this mindset I rather prefer "forcing" SFML developer to install XQuartz on their own so they can put freetype in their .app.

Now this is not a definitive decision. I'm open to discussion to find what's best for both developers and users. However this won't be changed until SFML 2.1. So we have time before us.

I'd personally be fine with grabbing a copy of the dylib and bundling it with my app similar to how you link with sfml itself, but sfml probably won't compile unless it's present at compile-time of the framework, no?

[Hiura]

Yes, but you don't actually need to build SFML to use it. Just download the last release from the website. 

[capz]

Oh I wasn't aware that there are prebuilt frameworks already

Anyway.. 
So I poked around in yet another clean install of 10.8 (making snapshots so I can revert from now on ) and I noticed some things which I thought were interesting:
SFML will in fact compile just fine without XQuartz installed if you make a (soft) symlink to libfreetype.6.dylib, called libfreetype.dylib. A bunch of libs and headers actually ship with the OS, and even though freetype is not the very latest version(2.4.4), the whole thing builds just fine.

As for running apps.. I've created an empty sfml project from the supplied templates and for me it doesn't work. I had to throw out all references to sfml libs and add the frameworks for it to compile. I've also added freetype (the version that ships with 10.8 ) to the project but it still keeps asking to install XQuartz when running the app. Not sure what's going on there 

Console.app shows the following output:
