Can you cross compiling with Ubuntu on arm?
For example, to use your standard PC, most likely x86, to build something that is usable on another machine or device that’s on another architecture, like ARM. In this post, I’ll explain how to do cross compiling for 32bit ARM (arm) or 64bit ARM (aarch64) using Debian 10 or Ubuntu 20.04 LTS.
Why do we need an ARM64 compiler in Ubuntu?
Here’s a small C++ program called arm64main.cpp. Here’s how to compile it. Note the -static flag. We need this because the cross compiler by default generates dynamic binaries that rely on an ARM64 version of the dynamic linker, which we don’t have.
How to cross compiling for arm or AArch64?
For x86_64 (standard PC): 64 bit ARM (or aarch64): Before we can start compiling, we need to install the necessary packages and tools for cross compiling for ARM. These include the standard tools needed for compiling native: jensd@deb10:~$ sudo apt install gcc make gcc-arm-linux-gnueabi binutils-arm-linux-gnueabi Reading package lists…
How to set up GCC for cross compile for arm?
How do I set up GCC for cross compiling for the ARM processor? The host would be on x86_64 ( AMD64 – Ubuntu 12.04 ) and the target would be ARM (Raspberry Pi as well as Pandaboard – will do separate compilations for each)?
Can you cross compile for 32 bit ARM?
Just to be clear, in this post, the build and target platform are x86_64 (standard PC) and the host is the ARM platform. I will cover both 32bit ARM (armv6, armv7 or simply arm) and 64bit ARM (aarch64). To find out for which of these (32 bit or 64 bit ARM) you need to compile, the easiest is to look at the output of uname -m.
Which is the best cross compiler for Linux?
This is the official cross-compiling method used at Arch Linux ARM. If you plan on building a lot of packages and want to speed up the process, the following guide will turn an x86 Linux computer into an ARM cross-compiler. It’s also much easier than most cross-compile setups.
