Compiling ERRORS about '__cxa_bad_cast' on Android using Irrlicht Render Engine

Hi, everyone.

I found this interesting particle system on irrlicht forum.
So i download "SPARK-1.5.5_SDK" and extract on my Android Eclipse Document, then add some sentences to Android.mk.
But when i compiled this particle part with irrlicht, some errors occur.
Like
"...
...SPK_System.cpp:62: undefined reference to '__cxa_bad_cast'
...
...SPK_Emitter.cpp:50: undefined reference to '__cxa_bad_cast'
...
...SPK_Modifier.cpp:51: undefined reference to '__cxa_bad_cast'
...
...SPK_Group.cpp:125: undefined reference to '__cxa_bad_cast'
...
...SPK_NormalEmitter.cpp:42: undefined reference to '__cxa_bad_cast'
"

Before that, i have tested other 3rd part(irrAI, irrBullet) on Irrlicht engine on Android, the renderer output is OK.
My only Changes on source code:
As renderer used irrlicht, so "SPK_GL_All.cpp", "SPK_SFML_All.cpp" are not included in $(libirrParticle_la_SOURCES)

By the way, i found all the compiling errors are "dynamic_cast operator" ERROR.

Please Help me.Thank you.
(Sorry, English is not my native language, maybe some expression is not good or correct.)

Which compiler do you use ?
Normally, dynamic_cast should compile fine, and '__cxa_bad_cast' is a compiler defined function (because of the double underscore)

Android NDK compiler
Command:
$NDK/ndk-build

Actually, its "arm-linux-androideabi-4.4.3"

Found that Android NDK Compiler is a modified GCC.
With plain gcc it compiles (was tested on Linux and Windows), but here it seems that dynamic_cast of references is not supported by the compiler (dynamic_cast<const T*> works).

Change the dynamic_cast<const T&> to dynamic_cast<const T*>. Do not forget to change the code that follow the dynamic_cast to work with a pointer and not a reference!

PS: why did you call SPARK 'IrrlichtParticle' ?

Darktib,

Hi, thanks for your apply.
I've found some useful informations from GOOGLE.
Now, compiled is OK, some changes is following:

Application.mk(before)
"
STLPORT_FORCE_REBUILD := true
APP_STL := stlport_static
"

Application.mk(after)
"
STLPORT_FORCE_REBUILD := true
APP_STL := gnustl_static
LOCAL_CPPFLAGS := -frtti
"

BTW, why did you call SPARK 'IrrlichtParticle' ?
Just a name, of course can be 'IrrlichtSPARK'.

SPARK effort with irrlicht on my Android phone.
Too amazing.

Darktib, good job. But only 2 demos using irrlicht. Have you any plan on port other demos on irrlicht renderer?

That's look really cool! Good job for finding the solution!

For the moment I'm working on SPARK 2.0 with Juff, maybe we'll port some demos to Irrlicht (but I don't think all, because demos have to show OpenGL an SFML too; you can still adapt the SPARK logic part, that's not really hard )

OK, i will spend some time on the I/Fs between IRRLICHT and SPARK.
I will try to port other demos on Irrlicht.

ps:This project is a GREAT one.
