[Android-development] Compiling Qt Android under Mac OS X

[Pekka Nikander]

[Sorry if this is a dup, but I searched the android-development mailing list and didn't find any previous discussion on this.]

I'm trying to add external display support to Qt Android, see bug #39244

https://bugreports.qt-project.org/browse/QTBUG-39244

I have a very preliminary, partial solution already in gitorius:

https://qt.gitorious.org/qt/pekkanikanders-qtbase/commit/96849690d8cf8a97f170046edb597e4575929bc2

Now I would like to test that.

However, I have trouble building Qt Android.  I'm following these instructions

http://qt-project.org/wiki/Qt5ForAndroidBuilding

When I run configure, under Mac OS X 10.9.5, I get lots of error messages, see below for the first few ones.

It looks like that compiling Qt Android assumes that you are compiling under Linux.  Is that so?  If so, where should I start to fix the compilation so that it works also under Mac OS X?
