安装libjpeg后“jpeglib.h：没有这样的文件或目录”？

Question

以下是我在MSYS中编译libjpeg-9的方法：

1. 装载D：/Qt/Qt5.1.1/Tools/mingw48_32/ / mingw
2. ./ configure --prefix = / mingw
3. 在jconfig.h中更改“#define HAVE_PROTOTYPES 1”
4. 使
5. make install

然后我编译了一个用python编写的演示，需要libjpeg的支持。正如“intall.txt”指示的那样，我检查了“include”目录中的“jpeglib.h jerror.h jconfig.h jmorecfg.h”和“lib”目录中的“libjpeg.a”。但是我得到了“致命错误：jpeglib.h：没有这样的文件或目录”。相关的环境变量如下：

1. 路径 - D：\ Qt \ Qt5.1.1 \ Tools \ mingw48_32 \ bin
2. lib - D：\ Qt \ Qt5.1.1 \ Tools \ mingw48_32 \ lib
3. 包括 - D：\ Qt \ Qt5.1.1 \ Tools \ mingw48_32 \ include

有人可以帮我解决吗？
