working on lib-android-ogre-3d on github, w/ issue

[chbfiv]

I'm creating an open source android build project for ogre. The project references the current 'default' branch and can be found here.
https://github.com/chbfiv/lib-android-ogre-3d

However I'm having an issue with the error below.

/home/chbfiv/dev/ogre//OgreMain/src/OgrePlatformInformation.cpp:44:32: error: sys/sysctl.h: No such file or directory
make: *** [/home/chbfiv/workspace/marble-madness/lib-android-ogre-3d/obj/local/armeabi-v7a/objs-debug/ogre-3d//OgreMain/src/OgrePlatformInformation.o] Error 1

I'm defining the flag as arg's into the build system, however it seems that it's not working because the path to that error is still being compiled.
LOCAL_CFLAGS += -D__ANDROID__
LOCAL_CPPFLAGS += -D__ANDROID__

looking below you can see the compare w/ OGRE_PLATFORM_ANDROID, which is defined by __ANDROID__

Also, thanks to http://www.ogre3d.org/tikiwiki/Ogre+And ... evelopment for the general direction. I think I'm close to having it building. next would be getting a demo working.

Hi chbfiv !!

I tried to compile your project and find out that it seems the TEGRA2 platform detection conficts with android in OgrePlatform.h. For me both linux and __arm__ was detected so it was compiled using OGRE_PLATFORM_TEGRA2 instead of OGRE_PLATFORM_ANDROID. See the code from OgrePlatform.h below

Code: Select all

#elif defined(linux) && defined(__arm__)
// TODO: This is NOT the correct way to detect the Tegra 2 platform but it works for now.
// It doesn't appear that GCC defines any platform specific macros.
#       define OGRE_PLATFORM OGRE_PLATFORM_TEGRA2
#elif defined(__ANDROID__)
#       define OGRE_PLATFORM OGRE_PLATFORM_ANDROID
#elif defined( __native_client__ ) 

Anyway, thank you for your project, i'm also trying to compile Ogre with ndk in a clean way and do not succeed. Your work is good and clean , thank you for that but there is still issues on wstring and other stuff. Does anyone has a pointer to a thread that explains properly how to build Ogre on android ? Especialy i would like to know what kind of OgreBuildSettings.h I should use for the compilation?

What is the right way to generate the OgreBuildSettings.h for ANDROID ?

Thank you all
