cygwin下编译ffmpeg执行./config通不过

Question

 在执行./config.sh之前，export TMPDIR=c:/cygwin/tmp 设置临时目录
$ ./config.sh
cygwin warning:
MS-DOS style path detected: c:/cygwin/tmp/ffconf.3cT2wgQs
Preferred POSIX equivalent is: /tmp/ffconf.3cT2wgQs
CYGWIN environment variable option "nodosfilewarning" turns off this warning.

Answer 1

我进toolchains\arm-linux-androideabi-4.4.3\prebuilt\windows\lib\gcc\arm-linux-androideabi\4.4.3看了 
arm-linux-androideabi/4.4.3/crtbegin.o和gcc/arm-linux-androideabi/4.4.3/crtend.o是有的啊

./config.sh是这样写的
#!/bin/bashPREBUILT=/home/kenny/android-ndk-r6b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows

Answer 3

是不是我的export TMPDIR=c:/cygwin/tmp 设置临时目录有问题呢？不知道该怎么修该这个了
我的config.sh前面为：
PREBUILT=/home/kenny/android-ndk-r6b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows
PLATFORM=/home/kenny/android-ndk-r6b/platforms/android-8/arch-arm

Answer 4

昨晚又试试，报的错误如下：我的NDK的环境变量设置的为
NDK_ROOT=~/android-ndk-r6b/
export NDK_ROOT

Answer 5

PREBUILT=/home/kenny/android-ndk-r6b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows
PLATFORM=/home/kenny/android-ndk-r6b/platforms/android-8/arch-arm
 设置成绝对路径就好了比方说D：/home/....

你这里的问题是，需要先export TMPDIR=E:/Android_Home/Software/cygwin/home/js/ffmpeg/jni/tmp 再运行./config.sh命令！
