因为采集来的图像要进行存储,所以用到了这个库....具体安装方法在网络上能找到很多,大都可以用
我下载了这个jpegsrc.v9a.tar.gz 地址:www.ijg.org
然后就进行了安装,随便下载到一个路径下,然后我在一个网站上看到了“作者: 何志强”写的一个安装脚本,稍微改了下版本号,存储成了个文件,然后source了…
#----where to download---- #ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v9a.tar.gz #----.tar.gz file name---- jpeg_tar_gz=jpegsrc.v9a.tar.gz #----which version---- ver_jpeg=jpeg-9a #----where to install---- jpeg=/usr/local/jpeg #----untar---- tar xzvf $jpeg_tar_gz #----install---- cd $ver_jpeg ./configure --prefix=$jpeg --enable-shared --enable-static make mkdir $jpeg mkdir $jpeg/include mkdir $jpeg/lib mkdir $jpeg/bin mkdir $jpeg/man mkdir $jpeg/man/man1 make install cd .. #----free---- rm -rf $ver_jpeg #----configuration information---- echo "---------------------------------------------------------------------" echo "please add following lines in you /etc/profile" echo "(" echo " tip:" echo " you can add these lines in a file named /etc/profile.jpeg," echo " and then add a line on the end of /etc/profile:" echo " . /etc/profile.jpeg" echo " it is simple,:)" echo "):" echo " PATH=""$""PATH:$jpeg/bin" echo " CPLUS_INCLUDE_PATH=""$""CPLUS_INCLUDE_PATH:$jpeg/include" echo " LD_LIBRARY_PATH=""$""LD_LIBRARY_PATH:$jpeg/lib" echo " LIBRARY_PATH=""$""LIBRARY_PATH:$jpeg/lib" echo " MANPATH=""$""MANPATH:$jpeg/man" echo "" echo " export PATH CPLUS_INCLUDE_PATH LD_LIBRARY_PATH LIBRARY_PATH MANPATH"
上边这段中echo "---------------------------------------------------------------------"
之后的内容手动照做就可以了
建一个叫profile_jpeg的文件,内容写在下面……
就这样JPEG库PC版本就搞定了…晚上再写装嵌入式版本的方法
