c - 在为 android 交叉编译 util-linux 库时出现错误

Question

我正在使用 arm-linux-androideabi 为 android 交叉编译 util-linux 库。

我创建了工具链并执行配置语句 ./configure --prefix=/opt/android --build=${BUILD} --host=arm-linux-androideabi --disable-rpath --without-util --without-ncursesw --without-ncurses --没有信息

在做 make 之后我得到以下错误。

请帮我解决这个问题。提前致谢。

关于重新声明的第一个警告是由于损坏的 NDK header 。在“统一 header ”之前，他们盲目地声明 fcntl() , ioctl() (也许还有更多)直接来自 <fcntl.h>和 <unistd.h>没有检查它们是否已经声明。统一 header 以正确的方式执行此操作，并且自 NDK r14 起可用，请参阅 here .

关于第二个问题 - 你可能有一个叫做 l 的东西和 _POSIX_VDISABLE意外定义为全局变量或函数。看起来像构建脚本中的一些问题。很高兴看到实际的编译器/链接器命令。
