make-standalone-toolchain.sh about android-cmake HOT 3 OPEN

OK, it seems does not support sudo, It works on windows Administrative users 
permissions, so running cygwin as an administrator solves the problem. 

echo "Create new NDK toolchain..."
#if this line cast the error:mkdir: cannot create directory `/tmp/ndk-...;
#you must add this line "none /cygdrive cygdrive binary,user,noacl,posix=0 0 0" 
to /etc/fstab file
$NDK_ROOT/build/tools/make-standalone-toolchain.sh --platform=$PLATFORM 
--install-dir=$TOP_FFMPEG_DIR/android-toolchain

it's because wherever you're running the script is read-only (check ls -l).

in the worst case chmod 777 -R the whole ndk dir, it will work.
