我正在尝试构建GDB，并且从这里签出了源代码：
https://secure-web.cisco.com/1gNMaTaLSpyPf04-64vyJyKpMnhYszFwToxEd5acy6VS3P271v2Vw2kWu-o5O16GAU92fTpsG5ezF48gddoDV7Adx8PaRyVUyENTYoGhf4DAL5SCpsboaD9mL8rtLqTcK7yirl321lqD9Cfnoz5vju88CQIffq80iTEn4g5SSY7g/https%3A%2F%2Fandroid.googlesource.com%2Ftoolchain%2Fgdb.git
我正在使用用于编译NDK应用程序的相同工具链，将bin文件夹添加到我的路径并运行config脚本：
./configure --host = arm-linux-androideabi
我收到此构建错误：
.././libiberty/getpagesize.c:64:1：错误：“ getpagesize”的重新定义
/home/xxxxx/android-ndk/arm_a14_tools/bin/../sysroot/usr/include/unistd.h:174:23：注意：此处“ getpagesize”的先前定义在此处
Makefile：679：目标“ getpagesize.o”的配方失败
make [2]：*** [getpagesize.o]错误1
你有什么主意吗 ？
最佳答案
我也遇到了我找到了两种解决方案。

2作为快速修复的技巧，暂时将本节注释掉
在unistd.h中：
#if 0
static __inline__ int getpagesize(void) {
extern unsigned int __page_size;
return __page_size;
}
#endif
