Android 运行时在windows上编译FFmpeg错误。/configure

我想使用FFmpeg在android上解码mp3和acc，我使用android-ndk-r7和最新的cygwin

我编写了一个shell config.sh，内容如下：

---

---

我打开cmd，做bash打开cygwin shell，然后做./config，问题出现了： “/cygdrive/c/android-ndk-r7/toolschains/arm-linux-androideabi-4.4.3/prebuild/windows/bin/arm-linux-androideabi-gcc无法创建可执行文件…”

config.log是：

我不知道发生了什么，是否有人知道发生了什么，谢谢。

确保在cygwin中正确设置了gcc的路径。您正在尝试交叉编译ffmpeg。在这种情况下，请确保路径中没有定义跨编译版本的gcc。

---

ffmpeg的许多模块不在cygwin中编译。检查cygwin架构是否兼容。检查

--arch和--os下可用的选项。

在这里，您可以找到问题的解决方案：

谢谢您的建议，我想ffmpeg版本可能无法在cygwin上运行。我按照另一个例子在linux上完成了它。这是url。
