OSX是OS

我正在使用Android GCC编译器来编译下面的类…
#include <stdint.h>
int main (void){
return 0;
}
我用以下命令做…
un@un:~/Development/Code/OpenGL$~/Development/Android/android-ndk-r8c/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86/bin/arm-linux-androideabi-gcc hello.c -o hello
我得到…

所以由于缺乏gcc知识(但有一些Google的能力),我发现这一点,并尝试…

我得到…

有人可以帮我做我做错了吗？我错过了一个链接吗？ Android.mk不是一个选项.
更新这不工作…

解决方法
您必须告诉GCC在哪里找到Android系统文件和标题.使用：
> ndk-build和一个带有BUILD_EXECUTABLE的Android.mk
>或–sysroot GCC选项
[1]
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := foo LOCAL_SRC_FILES := foo.c include $(BUILD_EXECUTABLE)
[2]
# Change `android-9` with the level you target /path/to/android-ndk-r8c/toolchains/arm-linux-androideabi-4.6/prebuilt\ /darwin-x86/bin/arm-linux-androideabi-gcc\ --sysroot /path/to/android-ndk-r8c/platforms/android-9/arch-arm/\ foo.c -o foo # Or generate a ready-to-use standalone toolchain (better) /path/to/android-ndk-r8c/build/tools/make-standalone-toolchain.sh \ --platform=android-9 \ --install-dir=/tmp/my-android-toolchain export SYSROOT=/tmp/my-android-toolchain/sysroot /path/to/arm-linux-androideabi-gcc --sysroot $SYSROOT foo.c -o foo
