libjpeg的交叉編譯

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

從http://www.ijg.org/files/網站下載lib庫的源文件.
開工:

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

=================================================
出錯:

[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，我們得先安裝 libtool工具。
=================================================

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

或按 原帖主方法：

從http://download.chinaunix.net/download/0007000/6039.shtml下載
得到: libtool-2.4.2.tar.xz
放到我們的Linux系統中:

網上說，tar.xz文件解壓 有2中辦法:
方式1：
    tar xvfJ ***.tar.xz
方式2:
    xz -d ***.tar.xz
    tar -xvf  ***.tar
我用方法1嘗試，報錯:

[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

於是，我採用方法2:
[root@localhost jpeg]# xz -d libtool-2.4.2.tar.xz
bash: xz: command not found
好吧， 我去給你安裝個xz工具，從 http://tukaani.org/xz/xz-4.999.9beta.tar.bz2
上面下載得到 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, 去之前的目錄，然後 xz -d libtool-2.4.2.tar.xz
得到: libtool-2.4.2.tar
然後：tar -xvf libtool-2.4.2.tar
得到: libtool-2.4.2 文件夾。
$ 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
## ------------------------- ##
## Configuring libtool 2.4.2 ##
## ------------------------- ##

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking build system type... arm-unknown-linux-gnu
checking host system type... arm-unknown-linux-gnu
configure: autobuild project... GNU Libtool
configure: autobuild revision... 2.4.2 ()
configure: autobuild hostname... localhost.localdomain
configure: autobuild mode... default
configure: autobuild timestamp... 20121116T063533Z
checking for arm-linux-gcc... arm-linux-gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out

checking whether we are cross compiling... configure: error: in `/opt/jpeg/libtool-2.4.2':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details

後來改爲:
[root@localhost libtool-2.4.2]# ./configure CC=arm-linux-gcc --host=arm-linux --prefix=/opt/jpeg/libtool-release
配置通過。

 

$ 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，得到我們的文件在 jpeg-6b-release 目錄下面。

 

下面我們再延伸一下，將8d版本的庫也編譯了吧。

[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

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

8 directories, 24 files

 

至此， 我們的8d版本的JPEG庫也編譯通過了，哈哈。。
