This article is about how to use raspberry pie 3B+ firmware to compile LEDE. I think it is very practical, so I share it with you. I hope you can get something after reading this article.

There is always a problem with the firmware on the Internet. Compile one by yourself here to record the process and the problems encountered.

Internal compiler error: Killed (program cc1plus)

Checking whether mknod can create fifo without root privileges

Prompt the problem of compilation time difference

[1] prepare the environment and dependencies first

Sudo apt update & & sudo apt upgradesudo apt-y install build-essential asciidoc binutils bzip2 gawk gettext git libncurses5-dev patch unzip zlib1g-dev lib32gcc1 libc6-dev-i386 subversion flex node-uglify gcc-multilib p7zip p7zip-full msmtp libssl-dev texinfo libglib2.0-dev xmlto qemu-utils upx-ucl libelf-dev autoconf automake libtool autopoint gcc gathers + cmake vim wget ntp ntpdate

[2] compilation

From here to back, there is no need for root users or sudo.

# download the source code git clone https://github.com/coolsnowwolf/ledecd ~ / lede# update dependent source. / scripts/feeds update-a & &. / scripts/feeds install-a # enter the configuration interface make menuconfig

Here git, update dependent source and later compilation and download process all need a good and fast network environment, ha, think of your own way.

[3] configuration

[4] compilation

# download the things used for compilation, it will be very slow make download VSAs

This process may encounter the above problems 0.2 and 0.3, and the solutions are

Solution: checking whether mknod can create fifo without root privileges do not use root users or sudo to use make-related commands, add environment variable export FORCE_UNSAFE_CONFIGURE=1 reference https://github.com/coolsnowwolf/lede/issues/200

0.3 solution: install ntpdate to synchronize time, sudo apt-get install ntp ntpdate, sudo ntpdate ntp1.aliyun.com

# start the official compilation of the system, single-threaded mode make venders-J1

Many problems may be encountered here, such as problem 0.1 mentioned above. The solution is:

Solution: internal compiler error: internal compiler error: Killed (program cc1plus) this is due to lack of memory, the compilation process requires a lot of memory, my machine only has 512m of memory, so I can add swap space to solve it. Reference https://www.cnblogs.com/liqinggai/articles/9023333.html

Add swap:

1. Create a partition file with a size of 2G

Sudo dd if=/dev/zero of=/swapfile bs=1M count=2048

two。 Generate swap file system

Sudo mkswap / swapfile

3. Activate the swap file

Sudo swapon / swapfile

4. Can be deleted later

Sudo rm / swapfile

It is done, and the compiled firmware is in ~ / lede/bin/targets/brcm2708/bcm2710
