Android NDK에 STL 포팅한것

출처 : http://xxw8393.blog.163.com/blog/static/37256834200910235723590/

Android NDK 已有 1.6，安装容易（解压便可），但使用上比较复杂，要与SDK的一起使用。NDK允许开发人员用C/C++语言编译部分的应用程序代码。

Linux 32/64-bit (x86)    android-ndk-1.6_r1-linux-x86.zip

增加 stlport, 可编译C/C++程序的代码为独立运行的 Android 应用程序

linux 방법

코드복사  cd ~/Android git clone git://umbel.mooo.com/ndk-wrappers.git export HOST=linux-x86 export NDK_DIR=~/Android/android-ndk-1.6_r1 export NDK_WRAPPERS_BASE=~/Android/ndk-wrappers export PATH=~/Android/ndk-wrappers/bin:$PATH 변경한다. ndk-wrappers/scripts/env-utils.sh SYSROOT="${NDK_DIR}/build/platforms/android-4/arch-arm" HOST=linux-x86 변경한다. ndk-wrappers/stlport/build/lib/android.mak --sysroot=$(NDK_DIR)/build/platforms/android-1.5/arch-arm \ 으로  --sysroot=$(NDK_DIR)/build/platforms/android-4/arch-arm \ cd ~/Android/ndk-wrappers ./env.sh ./setup.sh

STLPort 설치

코드복사  cd ~/Android/ndk-wrappers ./setup.sh

테스트 qsort.cpp

코드복사  #include <iostream> #include <stdlib.h> using namespace std; int sortFunction( const void *intOne, const void *intTwo); const int length = 10;   int main(void) {    int i,intArray[length];    for (i = 0; i < length; i++)    {       cout << "Enter a number [" << i << "]: ";       cin >> intArray[i];    }    cout << "\n";    qsort((void *)intArray, length, sizeof(intArray[0]), sortFunction);    for (i = 0; i < length; i++)       cout << "intArray [" << i << "]: " << intArray[i] << endl;    cout << "Done." << endl; return 0; } int sortFunction( const void *a, const void *b) {    int intOne = *((int*)a);    int intTwo = *((int*)b);    if (intOne < intTwo)       return -1;    if (intOne == intTwo)       return 0;    return 1; }

컴파일 및 테스트

코드복사  ~/Android/ndk-wrappers/bin/arm-linux-g++ -o qsort qsort.cpp -L~/Android/ndk-wrappers/stlport/build/lib/obj/arm-linux-gcc/so ~/Android/android-sdk-mac_x86-1.6_r1/tools/adb push qsort /data/local/bin/qsort ~//Android/android-sdk-mac_x86-1.6_r1/tools/adb shell chmod 755 /data/local/bin/qsort ~/Android/android-sdk-mac_x86-1.6_r1/tools/adb shell 进入shell 后 /data/local/bin/qsort

android gcc toolchain

pocketmagic 有一篇关于编译 android gcc toolchain 的方法可编译C/C++程序的代码为独立运行的 Android 应用程序
http://www.pocketmagic.net/?p=682

现附上已编译好的mac (androidgcc_mac.tgz) 及 linux (androidgcc_linux.tgz) 版本
使用方法如下

(1) 下载后解压

코드복사 mkdir -p ~/Android/androidgcc cd ~/Android/androidgcc tar -xzvf  ~/Documents/androidgcc_linux.tgz

(2) 下载agcc 脚本至 ~/Android/Projects/
http://www.pocketmagic.net/wp-content/uploads/2009/05/agcc

可用 mac / linux Terminal

코드복사 cd ~/Android/Projects/ curl -O http://www.pocketmagic.net/wp-content/uploads/2009/05/agcc

(3) agcc 安装方法

linux 用 Terminal 安装方法

复制代码 cd ~/Android/Projects/ chmod +x agcc

(4) 修改环境变量
linux

코드복사 export PATH=~/Android/androidgcc/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin:${PATH} 或 vi ~/.bash_profile 為 PATH=~/Android/androidgcc/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin:~/Android/android-sdk-linux_x86-1.6_r1/tools:"${PATH}"

(5) 测试 Hello, Android World!
必须先将手机上的USB调试（Debug）模式打开及手机连接到 USB

코드복사  cd ~/Android/Projects/ echo 'main() { printf("Hello, Android World!\n");}' > main.c ./agcc main.c -o main adb push main /data/local/bin/main adb shell chmod 775  /data/local/bin/main adb shell /data/local/bin/main

(6) 用 Makefile

코드복사 AGCC=~/Android/androidgcc #mac SDKTOOL=~/Android/android-sdk-mac_x86-1.6_r1/tools #linux #SDKTOOL=~/Android/android-sdk-linux_x86-1.6_r1/tools APP=hello #mac CC=$(AGCC)/prebuilt/darwin-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-gcc CPP=$(AGCC)/prebuilt/darwin-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-g++ #linux #CC=$(AGCC)/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-gcc #CPP=$(AGCC)/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-g++ LD=$(CPP) CPPFLAGS += -I$(AGCC)/bionic/libstdc++/include CFLAGS += -I$(AGCC)/system/core/include CFLAGS += -I$(AGCC)/hardware/libhardware/include CFLAGS += -I$(AGCC)/hardware/ril/include CFLAGS += -I$(AGCC)/dalvik/libnativehelper/include CFLAGS += -I$(AGCC)/frameworks/base/include CFLAGS += -I$(AGCC)/external/skia/include CFLAGS += -I$(AGCC)/out/target/product/generic/obj/include CFLAGS += -I$(AGCC)/bionic/libc/arch-arm/include CFLAGS += -I$(AGCC)/bionic/libc/include CFLAGS += -I$(AGCC)/bionic/libc/kernel/common CFLAGS += -I$(AGCC)/bionic/libc/kernel/arch-arm CFLAGS += -I$(AGCC)/bionic/libm/include CFLAGS += -I$(AGCC)/bionic/libm/include/arch/arm CFLAGS += -I$(AGCC)/bionic/libthread_db/include CFLAGS += -I$(AGCC)/bionic/libm/arm CFLAGS += -I$(AGCC)/bionic/libm CFLAGS += -I$(AGCC)/out/target/product/generic/obj/SHARED_LIBRARIES/libm_intermediates CFLAGS += -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -DANDROID -DSK_RELEASE -DNDEBUG CFLAGS += -include $(AGCC)/system/core/include/arch/linux-arm/AndroidConfig.h CFLAGS += -UDEBUG -march=armv5te -mtune=xscale -msoft-float -mthumb-interwork -fpic -fno-exceptions -ffunction-sections -funwind-tables -fstack-protector -fmessage-length=0 -Bdynamic LDFLAGS += -Wl,-T,$(AGCC)/build/core/armelf.x -Wl,-dynamic-linker,/system/bin/linker -Wl,--gc-sections -Wl,-z,nocopyreloc -Wl,--no-undefined -Wl,-rpath-link=$(AGCC)/out/target/product/generic/obj/lib LDFLAGS += -L$(AGCC)/out/target/product/generic/obj/lib -nostdlib $(AGCC)/out/target/product/generic/obj/lib/crtend_android.o $(AGCC)/out/target/product/generic/obj/lib/crtbegin_dynamic.o $(AGCC)/prebuilt/darwin-x86/toolchain/arm-eabi-4.2.1/lib/gcc/arm-eabi/4.2.1/interwork/libgcc.a LDFLAGS += -lutils -lc -lm -lstdc++ all:    $(APP) OBJS += $(APP).o $(APP):    $(OBJS)     $(LD) $(LDFLAGS) -o $@ $^ %.o:    %.c     $(CC) -c $(CFLAGS) $< -o $@ %.o:    %.cpp     $(CPP) -c $(CFLAGS) $(CPPFLAGS) $< -o $@ install: $(APP)     $(SDKTOOL)/adb push $(APP) /data/local/bin/$(APP)     $(SDKTOOL)/adb shell chmod 755 /data/local/bin/$(APP) run:     $(SDKTOOL)/adb shell /data/local/bin/$(APP) clean:     @rm -f $(APP).o $(APP)

hello.cpp

코드복사 #include <stdio.h> #include <utils/String8.h> using namespace android; int main() {    String8 str = String8("Hello Android\n");    str += "Hello C++\n";    str.append("\n... Android gcc toolchain ...\n");    printf(str);    return 0; }

테스트 hello.cpp

코드복사 make APP=hello make APP=hello install run

내가 중국싸이트에서 보고 그대로 다운받아서 실습해본것을 압축한 파일을 올립니다.
