Thank you,

It seems to be warnings.
You can try my docker image.

docker pull quectel/9x07_ubuntu1604_env

Hi @Bean.Wang-Q ,
I just used it and no change.
Do you have a guideline to use that command and configure environment?

I mean that you can use my docker image.
The password is 1.

Here is what you need to do
apt-get install --assume-yes perl mc re2c g++ g+┬▒multilib wget sudo python

apt-get install --assume-yes bison gcc make build-essential libc6-dev-i386 libncurses-dev wget coreutils diffstat chrpath cpio gawk sed texi2html texinfo unzip flex bc libssl-dev
update-alternatives --install /usr/bin/python python /usr/bin/python2 2700

it works now.
Thank you so much!
