Hi, "high hand", "cow man". In Chinese, "high hand" means you are expert in some professional area(imaging some one with his hands very high could achive sth that others can not); "cow man" means you are awsome. Ok, so far for hello, get to job. Android is the OS developed by google for cell phone, and now we'd like to make a game engine on it. And finally a compiling problem came to us. If you are familiar with this OS, please help. first angel script do passed the compile on ubuntu. And android's core is linux. But there is somthing different with their file <new> on android: #ifndef __NEW__ #define __NEW__ #include <stddef.h> //!!!! no extent "c++"{ here !!!!!!!!! namespace std { using ::size_t; struct nothrow_t {}; extern const nothrow_t nothrow; } void* operator new(std::size_t); void* operator new[](std::size_t); void operator delete(void*); void operator delete[](void*); void* operator new(std::size_t, const std::nothrow_t&); void* operator new[](std::size_t, const std::nothrow_t&); void operator delete(void*, const std::nothrow_t&); void operator delete[](void*, const std::nothrow_t&); inline void* operator new(std::size_t, void* p) { return p; } inline void* operator new[](std::size_t, void* p) { return p; } // these next two are not really required, since exceptions are off inline void operator delete(void*, void*) { } inline void operator delete[](void*, void*) { } //!!!! } !!!!!!!!!!!! #endif // __NEW__ and linux does. with makefile modified: CXX = arm-eabi-g++ Without "extent c++" we canot pass the compile. arm-eabi-g++ -g -Wall -fPIC -o obj/as_callfunc_x64_gcc.o -c ../../source/as_callfunc_x64_gcc.cpp In file included from ../../source/as_memory.h:75, from ../../source/as_config.h:666, from ../../source/as_callfunc_x64_gcc.cpp:39: /home/Administrator/open_src/android/android-ndk-1.5_r1/build/prebuilt/windows/arm-eabi-4.2.1/bin/../lib/gcc/arm-eabi/4.2.1/include/new:18: error: declaration of C function 'void* operator new(size_t, const std::nothrow_t&)' conflicts with /home/Administrator/open_src/android/android-ndk-1.5_r1/build/prebuilt/windows/arm-eabi-4.2.1/bin/../lib/gcc/arm-eabi/4.2.1/include/new:14: error: previous declaration 'void* operator new(size_t)' here /home/Administrator/open_src/android/androi d-ndk-1.5_r1/build/prebuilt/windows/arm-eabi-4.2.1/bin/../lib/gcc/arm-eabi/4.2.1/include/new:19: error: declaration of C function 'void* operator new [](size_t, const std::nothrow_t&)' conflicts with /home/Administrator/open_src/android/android-ndk-1.5_r1/build/prebuilt/windows/arm-eabi-4.2.1/bin/../lib/gcc/arm-eabi/4.2.1/include/new:15: error: previous declaration 'void* operator new [](size_t)' here /home/Administrator/open_src/android/android-ndk-1.5_r1/build/prebuilt/windows/arm-eabi-4.2.1/bin/../lib/gcc/arm-eabi/4.2.1/include/new:20: error: declaration of C function 'void operator delete(void*, const std::nothrow_t&)' conflicts with /home/Administrator/open_src/android/android-ndk-1.5_r1/build/prebuilt/windows/arm-eabi-4.2.1/bin/../ lib/gcc/arm-eabi/4.2.1/include/new:16: error: previous declaration 'void operator delete(void*)' here When we manually added this line to <new> on android, compile passed.

I modified the commandline as you say then here comes the problem again. But do thanks for your last reply.

commandline:

arm-eabi-gcc -nostdlib -Bdynamic -Wl,-T armelf.x -include AndroidConfig.h -lc -o test_main test_main.cpp crtbegin_dynamic.o crtend.o -L. -langelscript

GCC C++ programs usually need to link with -lstdc++, so try adding that to your commandline.

holly xx..

Now we tried to compile it by using android.mk rather then makefile in angelscript. android.mk is the special makefile for android os. now sth new came out..

I think may be you know what happened.

o mips x86, gonna do a little modification

Oh, good. Done. With a little modification , mission complete! compile ok, link ok!
1.There is no need to modify <new> on android

2.add two lines into as_config.h
#define AS_ARM
#define AS_NO_ATOMIC

3.change the name of as_callfunc_armasm.asm to as_callfunc_armasm.S

4.mofify it as below

5.final compile it with android way(android.mk).

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES:= as_callfunc_armasm.S as_arrayobject.cpp as_atomic.cpp as_builder.cpp as_bytecode.cpp as_callfunc.cpp as_callfunc_arm.cpp as_callfunc_mips.cpp as_callfunc_ppc.cpp as_callfunc_ppc_64.cpp as_callfunc_sh4.cpp as_callfunc_x86.cpp as_compiler.cpp as_context.cpp as_configgroup.cpp as_datatype.cpp as_generic.cpp as_gc.cpp as_memory.cpp as_module.cpp as_objecttype.cpp as_outputbuffer.cpp as_parser.cpp as_restore.cpp as_scriptcode.cpp as_scriptengine.cpp as_scriptfunction.cpp as_scriptnode.cpp as_scriptobject.cpp as_string.cpp as_string_util.cpp as_thread.cpp as_tokenizer.cpp as_typeinfo.cpp as_variablescope.cpp
LOCAL_PRELINK_MODULE := false
LOCAL_MODULE := angelscript
include $(BUILD_STATIC_LIBRARY)

Then everything's fine.
a simple test had been passed.
A few more needed.
Let's hope it shall go on well.

Thanks again litchlord.
