ubuntu下编译jpeg-6b[笔记]

先按装libtool

sudo apt-get install autoconf
sudo apt-get install libtool

遇到“bash: ./configure：/bin/sh^M：解释器错误: 没有那个文件或目录”

sed -i 's/\r$//' configure

将/usr/share/libtool文件夹复制到~/Documents
将libtool/build-aux复制到~/Documents
删除~/Documents/build-aux的config.sub和config.guess（快捷链接而已）

复制config.sub和config.guess

cp /usr/share/libtool/build-aux/config.sub ~/Documents/build-aux/config.sub
cp /usr/share/libtool/build-aux/config.sub ~/Documents/jpeg-6b/config.sub
cp /usr/share/libtool/build-aux/config.guess ~/Documents/build-aux/config.guess
cp /usr/share/libtool/build-aux/config.guess ~/Documents/jpeg-6b/config.guess

cd ~/Documents/libtool
./configure
make

得到libtool。要将libtool复制到jpeg6d目录下

cp ~/Documents/libtool/libtool ~/Documents/jpeg-6b/libtool

cd ~/Documents/jpeg-6b
./configure --disable-shared --enable-static
make
sudo make install

可以到/usr/local/lib下复制libjpeg.a文件了
