Hardware: Raspberry 4B+
Software: Ubuntu 18.04

The problems have been solved by performing the following steps:

1. Insall GoLang:
   wget https://dl.google.com/go/go1.13.7.linux-arm64.tar.gz #ARM64 architecture
   sudo tar xvzf go1.13.7.linux-arm64.tar.gz -C /usr/local/ #ARM64 architecture
   sudo ln -s /usr/local/go/bin/go* /usr/local/bin/
2. Install Docker:
   sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   sudo add-apt-repository "deb [arch=arm64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" #ARM64 architecture
   sudo apt-get update
   sudo apt-get install docker-ce docker-ce-cli containerd.io
3. Install nodejs
   curl -sL https://deb.nodesource.com/setup_13.x | sudo -E bash -
   sudo apt install -y nodejs #see version：$ nodejs -v
   sudo ln -s /usr/bin/nodejs /usr/bin/node
4. Install npm & gulp
   sudo apt-get install npm
   npm view npm version # see the latest version
   sudo npm install -g [email protected] # npm update to latest version, see the installed version：$ npm -v
   sudo npm install -g gulp-cli
5. Make Lantern
   git clone https://github.com/getlantern/lantern.git
   cd lantern/archive/
   make linux-arm

but I met another problem:
exec: "arm-linux-gnueabi-gcc": executable file not found in $PATH

from lanberry.

Software: Ubuntu 18.04

The problem has been solved by installing gcc-arm-linux-gnueabi complier:
$ sudo apt-get gcc-arm-linux-gnueabi complier:

but I met new problems:
berry@rasp:~/lantern/archive$ make linux-arm

Please refer to: https://xiazemin.github.io/MyBlog/golang/2019/06/30/lantern.html
Find out these two files:
modified: src/github.com/getlantern/flashlight/client/reverseproxy.go
modified: src/github.com/getlantern/flashlight/proxied/proxied.go
In 4 positions，change 'MaxIdleTime' to 'IdleConnTimeout'，then comment the method 'EnforceMaxIdleTime()'. Only need to revise 4 lines in these two files, then recomplie.
// In reverseproxy.go file, perform the following steps:

• MaxIdleTime: 30 * time.Second,
  //MaxIdleTime: 30 * time.Second,
• IdleConnTimeout:30 * time.Second,
  }
• transport.EnforceMaxIdleTime()
  //transport.EnforceMaxIdleTime()
  // In proxied.go file, perform following steps:
• tr.MaxIdleTime = 30 * time.Second
  //tr.MaxIdleTime = 30 * time.Second
• tr.IdleConnTimeout= 30 * time.Second
  //tr.EnforceMaxIdleTime()

Generate lantern_linux_arm, indicate successful compilation.

but I met new problem when I executed the following command:
berry@rasp:~/lantern/archive$ lantern_linux_arm
lantern_linux_arm: command not found

from lanberry.

this project is all about building it automatically. actually I had difficulties building it too.
I am working on making a automated build script and hosting the binaries using Github & Travis CI ...
but any help would definitely be appreciated.

for your problem maybe using this command helps: make docker-linux-arm

from lanberry.

I tested the command: make docker-linux-arm, and got the following error response:

$make docker-linux-arm

I also performed the command: make linux-amd64, and faced the similar problems:

Changing MaxIdleTime to IdleConnTimeout actually fixed the problem.
Thank you for your help.

i'm going to complete the build script soon.
