Errors building Qt 5.4 Alpha for Android under Linux ( QtAccessibilityDelegate.java : cannot find symbol ) ?
-
I have been using Qt 5.3.2. I want to see if Qt 5.4's improved improved scaling of widget styles based on DPI will benefit my Android / iOS widget app.
When I build Qt for Android I get errors related to QtAccessibilityDelegate.java and cannot find symbol.
Configure:

@I get the following errors when I make:

@Thanks for any advice,

Hi,
According to "this":http://developer.android.com/reference/android/view/View.AccessibilityDelegate.html, AccessibilityDelegate was introduced in Android SDK API 14 so try using SDK API 14 or greater.

Thank you Gene! I will re-configure to use API 15.
I am building on a 64-bit Ubuntu 14.04 LTS host. I started over building Qt 5.4.0 for Linux 64-bit. I figured if I failed at building Qt Linux I should not even try building Qt Android. After installing many additional dependencies the build finally succeeded.
I am getting many missing header files when I configure to build Qt 5.4.0 for Android. I expect I need to install all the 32-bit package equivalents of the 64-bit packages I had to install to build Qt 5.4.0 Linux for 64-bit.
Would it be easier to build Qt Android under a 32-bit Linux host rather than a 64-bit Ubuntu 14.04LTS ?
I have already run into problems simply trying to build 32-bit and 64-bit Qt apps under the same 64-bit Ubuntu. The mesa OpenGL 32-bit and 64-bit packages do not like to install side-by-side and the last one installed wins. I am concerned there may be other 32-bit/64-bit devel packages that may not play well together.
Thank you for your help,
-Ed
