Ubuntu18.04 交叉编译 jpegsrc.v6b （arm-linux）

 

1、下载 jpegsrc.v6b 的源码：jpegsrc.v6b.tar.gz，然后解压到/home/work 目录下

2、进入  /home/workjpeg-6b 目录并建立如下编译脚本 build.sh：

export PATH=/opt/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf/bin:$PATH

./configure \
	CC=arm-linux-gnueabihf-gcc \
	--prefix=/opt/libjpeg-arm \
	--exec-prefix=/opt/libjpeg-arm \
	--enable-shared \
	--enable-static

make 

sudo make install

我的安装目录是：/opt/libjpeg-arm ， 所以在编译之前先建立如下目录：

        /opt

              /libjpeg-arm

                                /bin

                                /include

                                /lib

                                /man

                                         /man1

3、添加可执行权限，并执：

              chmod +x build.sh

              ./build.sh

4、我的编译过程中产生了如下错误：

解决方法如下：

参考：  解决linux64位安装jpeg 出错make: ./libtool: Command not found  

1）编译安装libtool-2.2.6：

     下载  libtool-2.2.6 源码并解压，然后执行如下命令，编译安装：

      ./configure

       make 

       sudo make install

2）拷贝如下文件到  jpegsrc.v6b 目录，然后重新执行 build.sh 脚本：

    我是在  /home/work//jpeg-6b 目录下执行的如下命令：

      cp /usr/share/libtool/build-aux/config.sub ./

      cp /usr/share/libtool/build-aux/config.guess ./
