Android - project build problem in pngrtran.c


#1

Hi Jules!

Just created a default project on my Mac with the Introjucer, and did this. Using android-ndk-r8b …:

cd Builds
ant release

...
...

-pre-build:
     [exec] Compile++ thumb  : juce_jni <= Main.cpp

Is this a known problem? If not, which NDK version are you using…?! :slight_smile:

EDIT: by coincidence, I’ve noticed that if I add this (see http://www.rawmaterialsoftware.com/viewtopic.php?f=13&t=11711) to jni/Android.mk, it builds OK!

#Turn-off thumb mode, generate 32-bit code instead!
#This gives a huge performance boost!
LOCAL_ARM_MODE := arm

Best wishes,

Pete

Compiler bugs triggered by code in libpng are a bit beyond my remit, I’m afraid!

The LOCAL_ARM_MODE setting sounds like a good thing if you’re building for the newer architectures, but am I right in thinking this should only be added if the architecture list only include armabi-v7 or later? At the moment, the introjucer’s default is to do that and the older armabi, which I guess would be broken by this flag (?)
