Linux3.4.39系统下交叉编译openssl提示Command not Found
已经成功安装arm-cortex_a9-eabi-4.7-eglibc-2.18编译器并且配置了PATH在终端下输入：echo $PATH
输出：/home/heeee/bin:/home/heeee/.local/bin:/usr/local/arm-cortex_a9-eabi-4.7-eglibc-2.18/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
在终端下输入：arm-cortex_a9-linux-gnueabi-gcc -v
输出：Using built-in specs.

目测可以保证编译器已经安装成功且PATH路径配置成功
进入openssl目录下输入：sudo make
