OPENCV 在MINGW 环境下的编译

因为某种原因，需要在MINGW下编译OPENCV，本以为是一个比较简单的事情，孰知竟然也陆陆续续花了不少的精力，即使到现在这个地步，也还有部分不甚满意的地方。综合看，OPENCV的的正常运行需要很多库的支持。在MS的VC++和正常的LINUX发布版本下，这些支持都是默认的，而在MINGW 下，却需要一一提供，因此也颇费一番周折，先把过程列举如下，希望能够今后做同样事情的人有所裨益。

第1步：下载 MINGW 和 MSYS

* 下载的版本是：MSYS-1.0.10.exemsysDTK-1.0.1.exe 和 MinGW-5.1.4.exe。
* 按照下载软件的基本提示，分别安装到 c:\mingw 和 c:\msys\1.0运行
* 问题：直接运行 msys.bat 出现问题，控制台窗口无法启动。所有的命令都出现 " Couldn't reserve space for cygwin's heap"
上网查找问题，解决方法是用 rebase 进行处理。 具体方法是：
- 启动CMD命令行程序，在DOS窗口下，依次运行：
cd c:\msys\1.0\bin
rebase -b 0x30000000 msys-1.0.dll
* 编辑 /etc/fstab，写入下面的映射关系：
c:/mingw /mingw
c:/mingw /usr/local
* 编辑 /etc/profile，在文件末尾增加下面几行：
#进入的缺省目录是根目录
cd "/"
#列举目录时有颜色信息
alias ls='ls --color'
alias dir='ls --color'

第2步：下载 OPENCV V1.0 FOR LINUX

* 下载OPENCV1.0 for linux 解压到/home/opencv（就是 c:\msys\1.0\home目录下）
* 从第3步开始到开始配置OPENCV，均是做一些准备工作以及配置必要的支持库。

第3步：下载pkg-config

下载地址为：http://rt.openfoundry.org/Foundry/Project/Download/。将二进制的解压包解压拷贝到 c:\mingw目录下；

第4步：安装 GTK，保证对图像I/O的支持

* 下载下面的文件，解压后释放到 C:\MinGW 目录下
* pkg-config-0.23.zip
* libiconv-1.9.1.bin.woe32.zip
* gettext-0.14.5.zip
* gettext-dev-0.14.5.zip
* pango-1.16.4.zip
* pango-dev-1.16.4.zip
* cairo-1.4.14.zip
* cairo-dev-1.4.0.zip
* zlib-1.2.3.zip
* libpng-1.2.8.zip
* libpng-dev-1.2.8.zip
* atk-1.20.0.zip
* atk-dev-1.20.0.zip
* gtk+-2.12.8.zip
* gtk+-dev-2.12.8.zip
* libintl-0.14.4-lib.zip

第5步：安装编译FFMPEG

* 下载地址是：http://download.chinaunix.net。将下载的ffmpeg-0.4.9- p20060302.tar.bz2 解压到/home/ffmpeg 下，
* 编译
./configure --enable-memalign-hack
make
make test
make install
* 注意这个包直接安装到 c:/program files/ffmpeg 中，需要把该目录下的 ./lib 和 ./include 目录移动到 c:/mingw （也就是 /usr/local）下， ffmpeg.exe 移到 c:/mingw/bin 下。

第6步：编译JPEG/JASPER/TIFF 等图像库

* 下载 jpegsrc.v6b.tar.gz，jasper-1.900.1.zip，tiff-3.8.2-3-src.tar.bz2
* 依次安装说明编译、测试、安装。

第7步：拷贝GTK所需要的运行库

iconv.dll
intl.dll
libatk-1.0-0.dll
libgdk-win32-2.0-0.dll
libgdk_pixbuf-2.0-0.dll
libgtk-win32-2.0-0.dll
libiconv2.dll
libpango-1.0-0.dll
libpangowin32-1.0-0.dll

第8步：编译 OPENCV

* 运行配置文件：
./configure --without-carbon --without-quicktime --without-1394libs --without-python

--without-swig --enable-static --disable-shared --disable-apps
* 配置参数定义是
--without-gtk:忽略gtk＋2.0 windows
--without-carbon: 不使用Mac OS上的X库
--without-quicktime
--without-1394libs
--without-python
--without-swig
--enable-static :生成静态库
--disable-shared:不生成动态库
* 配置的运行结果如下

$ ./configure --without-carbon --without-quicktime --without-1394libs --witho
ut-python --without-swig --enable-static --disable-shared --disable-apps

Now run make ...

* 编译：
make
* 安装：
make install
* 检查：可以看到能够生产 cxcore 和 cv 的测试文件，并且测试通过。
make check
* 安装
make install
将库和头文件分别安装到 /usr/local/lib 和 /usr/local/include/opencv 下

第9步：测试

* 不需要图像I/O操作的，可以自己用下列方式编译：
g++ -o sample.exe sample.c -I/usr/local/include/opencv -L/usr/local/lib -lcv -lcvaux
-lcxcore -lml -lhighgui
* 需要图像I/O操作的，用下面方式编译：
g++ -o sample.exe sample.c -I/usr/local/include/opencv
-L/usr/local/lib -lhighgui -lcv -lcxcore -lcvaux -lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0
-lpangowin32-1.0 -lpangocairo-1.0 -lpango-1.0 -lcairo -lgdk_pixbuf-2.0 -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl -ljpeg -lpng -ltiff -ljasper -lgthread-2.0

第10步：需要解决的几个问题

* HIGHGUI/window_gtk.cpp 不编译的问题；解决办法是重新改写 window_gtk.cpp 程序，将
#ifdef HAVE_GTK
...
#endif
有关定义GTK的预编译指令注释掉
* 解决图像I/O问题：如果图像的I/O函数无法使用，在编译时候总是出现如下错误：
c:/mingw/lib/libhighgui.a(loadsave.o): In function `Z41__static_initialization_a
nd_destruction_0ii':
c:/msys/1.0/home/opencv/otherlibs/highgui/loadsave.cpp:337: undefined reference
to `cvShowImage'
collect2: ld returned 1 exit status
* 修改 /usr/local/include/jmorecfg.h 中定义 boolean 的地方，解决 boolean 的定义冲突，注释掉 boolean 的定义
#ifndef HAVE_BOOLEAN
//typedef int boolean;
#endif


第11步：遗留的几个问题

（1）JPEG文件的读取有问题，就是说 cvLoadImage 不能正确读取 jpeg 文件；
（2）cvSaveImage 有问题，无法存图片；
（3）FFMPEG无法使用，故视频不能做处理；

第12步：编译SAMPLES/C下的样例程序

编辑 makefile.gnu
LINKFLAGS = -L"/usr/local/lib" -lhighgui -lcv -lcxcore -lcvaux -lgtk-win32-2.0

-lgdk-win32-2.0 -latk-1.0 -lpangowin32-1.0 -lpangocairo-1.0 -lpango-1.0 -lcairo

-lgdk_pixbuf-2.0 -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl -ljpeg -lpng -ltiff -ljasper

-lgthread-2.0

替换原有的 LINKFLAGS 变量

输入指令：
make -f makefile.gnu
编译，然后运行
