libjpeg的交叉编译

转自：  http://blog.csdn.net/ypist/article/details/8190966

从http://www.ijg.org/files/网站下载lib库的源文件.
开工:

 tar -xzvf jpeg-6b.tar.gz
 cd jpeg-6b
 mkdir /opt/jpeg/jpeg-6b-release
 ./configure CC=arm-linux-gcc --prefix=/opt/jpeg/jpeg-6b-release --enable-shared --enable-static --host=arm-linux
 mkdir /opt/jpeg/jpeg-6b-release/bin
 mkdir /opt/jpeg/jpeg-6b-release/include
 mkdir /opt/jpeg/jpeg-6b-release/lib
 mkdir /opt/jpeg/jpeg-6b-release/man
 mkdir /opt/jpeg/jpeg-6b-release/man/man1
 make

=================================================
出错:

 [root@localhost jpeg-6b]# make
 ./libtool --mode=compile arm-linux-gcc -O2  -I. -c ./jcapimin.c
 make: ./libtool: Command not found
 make: *** [jcapimin.lo] Error 127

所以，我们得先安装 libtool工具。
=================================================

   sudo yum install libtool libtool-ltdl libtool-ltdl-devel

或按 原帖主方法：

从http://download.chinaunix.net/download/0007000/6039.shtml下载
得到: libtool-2.4.2.tar.xz
放到我们的Linux系统中:

网上说，tar.xz文件解压 有2中办法:
方式1：
    tar xvfJ ***.tar.xz
方式2:
    xz -d ***.tar.xz
    tar -xvf  ***.tar
我用方法1尝试，报错:

 [root@localhost jpeg]# tar xvfJ libtool-2.4.2.tar.xz
 tar: invalid option -- J
 Try `tar --help' or `tar --usage' for more information.
 [root@localhost jpeg]# tar xvfj libtool-2.4.2.tar.xz
 bzip2: (stdin) is not a bzip2 file.
 tar: Child returned status 2
 tar: Error exit delayed from previous errors

于是，我采用方法2:
[root@localhost jpeg]# xz -d libtool-2.4.2.tar.xz
bash: xz: command not found
好吧， 我去给你安装个xz工具，从 http://tukaani.org/xz/xz-4.999.9beta.tar.bz2
上面下载得到 xz-4.999.9beta.tar.bz2。
　　1、tar -jxvf xz-4.999.9beta.tar.bz2
　　2、cd xz-4.999.9beta
　　3、./configure --prefix=/
　　4、make && make install
OK, 去之前的目录，然后 xz -d libtool-2.4.2.tar.xz
得到: libtool-2.4.2.tar
然后：tar -xvf libtool-2.4.2.tar
得到: libtool-2.4.2 文件夹。
$ cd libtool-2.2.4/ 

 [root@localhost libtool-2.4.2]# ./configure CC=arm-linux-gcc --host=arm-linux --build=arm-linux --prefix=/opt/jpeg/libtool-release

 If you meant to cross compile, use `--host'.
 See `config.log' for more details

 后来改为:
 [root@localhost libtool-2.4.2]# ./configure CC=arm-linux-gcc --host=arm-linux --prefix=/opt/jpeg/libtool-release
 配置通过。

 

 $ make && make install
 [root@localhost libtool-2.4.2]# ls ../libtool-release/bin
 libtool  libtoolize
 [root@localhost libtool-2.4.2]# cp ../libtool-release/bin/* ../jpeg-6b/
 [root@localhost libtool-2.4.2]# cd ../jpeg-6b
 ./configure CC=arm-linux-gcc --prefix=/opt/jpeg/jpeg-6b-release --enable-shared --enable-static --host=arm-linux
 make && mak install

 

至此，得到我们的文件在 jpeg-6b-release 目录下面。

 

下面我们再延伸一下，将8d版本的库也编译了吧。

 [root@localhost jpeg]# cp /mnt/hgfs/jpeg_lib/jpegsrc.v8d.tar.gz ./
 [root@localhost jpeg]# tar zxvf jpegsrc.v8d.tar.gz
 [root@localhost jpeg-8d]# ./configure CC=arm-linux-gcc --prefix=/opt/jpeg/jpeg-8d-release --enable-shared --enable-static --host=arm-linux
 [root@localhost jpeg-8d]# make && make install
 [root@localhost jpeg-8d]# cd ../jpeg-8d-release/
 [root@localhost jpeg-8d-release]# tree

             |-- rdjpgcom.1
             `-- wrjpgcom.1

 8 directories, 24 files

 

至此， 我们的8d版本的JPEG库也编译通过了，哈哈。。
