C++与NDK平台错误帮助“_IOR”在此范围内未声明
问题描述：
谁能告诉我为什么当编译cpp的代码与NDK我得到这个错误：C++与NDK平台错误帮助“_IOR”在此范围内未声明
C:/ndk/samples/fmservice/src/jni/JFmRxNative.cpp:304:24: error: expected primary-expression before 'struct'
C:/ndk/samples/fmservice/src/jni/JFmRxNative.cpp:304:24: error: '_IOR' was not declared in this scope
line 304 : res = ioctl(radio_fd,VIDIOC_QUERYCAP,&cap); character 24: VIDIOC_QUERYCAP
次我使用C：\ NDK \平台\ android-14文件
答
接缝我需要补充这个#include <sys/ioctl.h>
