分享安装jpeg library显示jconfig.h is unchanged，求高手帮忙！
在cygwin（Unix）下安装了jpeg library，但是无法creating jconfig.h
$ ./configure
checking for gcc... gcc
checking whether the C compiler (gcc ) works... yes
checking whether the C compiler (gcc ) is a cross-compiler... no
checking whether we are using GNU C... yes
checking how to run the C preprocessor... gcc -E
checking for function prototypes... yes
checking for stddef.h... yes
checking for stdlib.h... yes
checking for string.h... yes
checking for size_t... yes
checking for type unsigned char... yes
checking for type unsigned short... yes
checking for type void... yes
checking for working const... yes
checking for inline... __inline__
checking for broken incomplete types... ok
checking for short external names... ok
checking to see if char is signed... yes
checking to see if right shift is signed... yes
checking to see if fopen accepts b spec... yes
checking for a BSD compatible install... /usr/bin/install -c
checking for ranlib... ranlib
checking libjpeg version number... 62
creating ./config.status
creating Makefile
creating jconfig.h
jconfig.h is unchanged
看install.doc上说，If you are on a Unix machine, you may not need to read this file at all.
Try doing
./configure
可是运行./configure后，卡在了jconfig.h is unchanged，请求高手解答一下菜鸟的问题，万分感谢！！！！！！

到这个文件./configure看看，“jconfig.h is unchanged”是怎么回事，看上面好像已经生成Makefile了，是不是已经可以编译安装了

$ install Makefile /cygdrive/c/jpeg6 这样安装，是对的吗？
[/quote]呃，抱歉，linux下是直接make和make install，但没在cygwin下用过make，不太清楚呢。。

新手一枚，请教一下您，现在是生成makefile了，在cygwin（Unix）下，想用类似于Linux下的make指令，怎么弄呢？我看网上的教程，都是make或是make install，但是cygwin里显示“-bash: make: command not found”。。。刚开始学习的新手，很多不懂的地方，麻烦您了！

意思是编辑configure，看看jconfig.h is unchanged是什么原因导致的；
或者找到jconfig.h，换个名字备个份，再./configure看还是不是报jconfig.h is unchanged
再说，creating Makefile // 这里不是生成了makefile了么；
