Dear Ladies or Gentelman:

    My MCU can’t connect to the ubuntu’s apt-source(like Ubuntu,aliyun,163 etc). So It certainly can’t use the command “sudo apt-get install gcc" to make it all right.
    So I want to know how to install gcc in the way of offline in ubuntu18.04.
    I search the solution from the internet then find one:https://blog.csdn.net/weixin_40671425/article/details/92762839. But unfortunately, it worked wrong on the steps: " ./configure --disable-multilib --prefix=/data2/upchen/MyPackages/gcc/gcc-5.4.0 --enable-add-ons ". The result is as follows:
---------------------linux@test:~/gcc-5.4.0$ ./configure --disable-multilib --prefix=/data2/upchen/MyPackages/gcc/gcc-5.4.0 --enable-add-ons

Thanks for the kind of selfless help in good faith.
