我在编译cc1: error: unrecognized command line option '-std=c11'项目时遇到此错误。所有相关问题都建议使用 4.7 以上的 gcc，但我已经有 4.7 以上的 gcc。这是详细信息
gcc version 6.3.0 20170519 (Ubuntu/Linaro 6.3.0-18ubuntu2~16.04)
我正在尝试编译这个https://github.com/rhdunn/espeak/tree/master/android. 问题发生在这个文件中https://github.com/rhdunn/espeak/blob/master/android/jni/Android.mk而 ndk-build。
这就是我正在做的事情
-vbox:~/eSpeak/espeak-master/android/jni$ ndk-build
Compile mips : ttsespeak <= case.c
cc1: error: unrecognized command line option '-std=c11'
make: *** [/home/apertium/eSpeak/espeak-master/android/obj/local/mips/objs/ttsespeak/__/__/src/ucd-tools/src/case.o] Error 1
ndk-build V=1 命令将给出以下日志。

在...的帮助下大卫·福斯特我发现上述错误是由于 Android NDK 包含自己的 C 编译器，所以我的 NDK 使用的是 GCC 4.6，它不支持 C11。所以我将我的 NDK 更新至 r16并导致以下错误。

我为此使用了虚拟盒。但是当我尝试在安装了 ubuntu 的系统上编译相同内容时，没有任何问题。一切都顺利进行并编译完成。所以我猜问题出在我的虚拟盒上。
