Question

我试图通过以下脚本编译ffmpeg，但编译时遇到错误:(使用Windows 7 - android ndk 7rb和cygwin）

s@s-PC /cygdrive/f/export/ffmpeg-0.8.10
$ ./setup.sh
F:/Compiler/android-ndk-r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/wind                                                                                                    ows/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

这是我的剧本：

有什么想法吗？

Answer 1

您没有转义./configure行（以及以下某些行）的换行符，因此标志被视为命令而不是标志。显然--extra-cflags不是一个有效的命令，缺少这些标志也会使配置失败。
