为qt-embedded添加jpeg库的交叉编译方法for arm
下载jpegsrc.v6b.tar.gz
解压
tar -xzf jpegsrc.v6b.tar.gz
cd jpeg-6b
[root@SJTU-LIUJIAN jpeg-6b]# ./configure --enable-shared
[root@SJTU-LIUJIAN jpeg-6b]# make
修改生成的Makefile文件:
prefix = qt-embeddedd的文件夹路径(eg: /home/qt-2.3.10)
CC= /usr/local/arm/2.95.3/bin/arm-linux-gcc
AR= /usr/local/arm/2.95.3/bin/arm-linux-ar rc
AR2= /usr/local/arm/2.95.3/bin/arm-linux-ranlib
下载jpegsrc.v6b.tar.gz
解压
tar -xzf jpegsrc.v6b.tar.gz
cd jpeg-6b
[root@SJTU-LIUJIAN jpeg-6b]# ./configure --enable-shared
[root@SJTU-LIUJIAN jpeg-6b]# make
修改生成的Makefile文件:
prefix = qt-embeddedd的文件夹路径(eg: /home/qt-2.3.10)
CC= /usr/local/arm/2.95.3/bin/arm-linux-gcc
AR= /usr/local/arm/2.95.3/bin/arm-linux-ar rc
AR2= /usr/local/arm/2.95.3/bin/arm-linux-ranlib
保存
在你的qt-embedded中建立man/man1文件家,否则安装jpeg库时会出错
[root@SJTU-LIUJIAN jpeg-6b]#mkdir -p qt-2.3.10/man/man1
最后:
[root@SJTU-LIUJIAN jpeg-6b]# make install
就可以给qt-embedded添加好for arm的libjpeg库.
向下面的目录中也拷贝一份:
/usr/local/arm/2.95.3/arm-linux/lib
拷贝 jconfig.h jmorecfg.h jpeglib.h 到
/usr/local/arm/2.95.3/arm-linux/include/
