用 NDK + cygwin 编译 ffmpeg，无法建立临时文本

Question

最近在windows平台下做ffmpeg到安卓的移植。用ndk r5+cygwin 处理 ffmpeg 目录下的config.sh文件时，路径全部设置正确，然后报这个错误：

C compiler test failed.

网上找了一下是需要设置

$export TMPDIR=d:/temp

可是我设置完了之后，cygwin又给我报无法建立临时文件的错误

$ ./config.sh
.nable to create temporary file in d:/temp

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.

求大神们帮帮我啊，这怎么解决？感觉就差一步了。

我的config.sh文件如下

#!/bin/bash
export TMPDIR="d:/temp"
 PREBUILT=${ndk}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows
 PLATFORM=android-4
 ARCH=--arch=arm
 ./configure
