Question

I am getting this error

/AppData/Local/Temp/ffconf.dkWUWsGo.c:1:20: fatal error: newlib.h: No such file or directory
 #include <newlib.h>

while compiling for ffmpeg.

Answer 1

From the path you provided, I guess the file is not present there anymore, because the Temp folder is used for temporary files. Probably you opened an archive (.zip, .rar, .tar, .jar), and after you closed it, the temporary files were deleted. Extract the files to a permanent directory from where you can use them.

As far as I understand from the error log you are trying to cross compile FFmpeg for Android, but I am not sure if Android NDK has a prebuilt newlib version shipped with it. You could check the corresponding platform directory in NDK if it has the include or library, but my assumption is that you will have to build newlib for ARM before you can do this. Btw - last time I compiled FFmpeg for Android I didn't have the issues you got - are you using a correct target? Maybe the newlib is imported because of a wrong architecture.
