[osg-users] [build] Building the android examples with Eclipse on mac

[Lonni Besançon]

Hi,

I'm completely new to openSceneGraph. I have it running more or less on my mac (I still encounter some weird segmentation fault on a code that works perfectly for a friend of mine on Linux) but appart from that I guess I'm fine with it.

However I would like to work on android. I do know how to use the native development on android and I have tried to build one of the exemples: the one for openGLES1. My problem is that I cannot use ndk-build without getting over and over the same mistake:



Code:

[armeabi] Compile++ thumb: osgNativeLib <= osgNativeLib.cpp
In file included from jni/OsgMainApp.hpp:21:0,
                 from jni/osgNativeLib.cpp:7:
/Users/lonnibesancon/Desktop/OpenSceneGraph-3.2.2-rc2/buildandroid/include/osg/GL:124:35: fatal error: GL/gl.h: No such file or directory

compilation terminated.
make: *** [obj/local/armeabi/objs/osgNativeLib/osgNativeLib.o] Error 1



For some reasons, the include is not complete on the piece of code above, the include that doesn't work is GL/gl.h.

Now I have MAC OS Yosemite, the ndk 10 and I have modified the Android.mk to have

Code:
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := osgNativeLib
### Main Install dir
OSG_ANDROID_DIR	:= /Users/lonnibesancon/Desktop/OpenSceneGraph-3.2.2-rc2/examples/osgAndroidExampleGLES1
LIBDIR 			:= $(OSG_ANDROID_DIR)/obj/local/armeabi

FRAMEWORK = -framework GLUT
FRAMEWORK += -framework OpenGL 

ifeq ($(TARGET_ARCH_ABI),armeabi-v7a)
	LOCAL_ARM_NEON 	:= true
	LIBDIR 			:= $(OSG_ANDROID_DIR)/obj/local/armeabi-v7a
endif

### Add all source file names to be included in lib separated by a whitespace

LOCAL_C_INCLUDES:= /Users/lonnibesancon/Desktop/OpenSceneGraph-3.2.2-rc2/buildandroid/include
LOCAL_CFLAGS    := -Werror -fno-short-enums
LOCAL_CPPFLAGS  := -DOSG_LIBRARY_STATIC 

LOCAL_LDLIBS    := -llog -lGLESv1_CM -ldl -lz -lgnustl_static 
LOCAL_SRC_FILES := osgNativeLib.cpp OsgMainApp.cpp OsgAndroidNotifyHandler.cpp
LOCAL_LDFLAGS   := -L $(LIBDIR) \
-losgdb_dds \
-losgdb_openflight \
-losgdb_tga \
-losgdb_rgb \
-losgdb_osgterrain \
-losgdb_osg \
-losgdb_ive \

-losgdb_deprecated_osgvolume \
-losgdb_deprecated_osgtext \

-losgGA \
-losgFX \
-losgDB \
-losgAnimation \
-losgUtil \
-losg \
-lOpenThreads

include $(BUILD_SHARED_LIBRARY)


.

Finally, this is the command I'm using:


> ~/Desktop/OpenSceneGraph-3.2.2-rc2/examples/osgAndroidExampleGLES1$ ../../../../android-ndk-r10e/ndk-build


Hope my questions is not dumb and you can help me out.

Thanks in advance anyway;

Cheers,
Lonni
