I’m looking for materials or links about cross-compiling, like eabi, etc. I’m new to Linux-based cross-compiling, and I want to develop my knowledge.

From Install the ARM cross compiler toolchain on Ubuntu:

How to install on Ubuntu the complete toolchain to cross compile the
Linux kernel, the Linux device drivers, the Linux applications and the
boot loader like as AT91Bootstrap and its derivatives like AcmeBoot
and AriaBoot.

This procedure has been tested on Linux Ubuntu 16.04. The same ARM cross compiler toolchain
is in the default Ubuntu repositories up of Ubuntu 16.04-20.04.

###Install the Cross Compilers, utilities, etc.

Install the GCC, G++ cross compilers and support programs by typing:

sudo apt install libc6-armel-cross libc6-dev-armel-cross
sudo apt install binutils-arm-linux-gnueabi
sudo apt install libncurses5-dev

If you are using an Arietta,
Aria or FOX
G20 board:

sudo apt install gcc-arm-linux-gnueabi
sudo apt install g++-arm-linux-gnueabi

If you are using an Acqua or
RoadRunner board:

sudo apt install gcc-arm-linux-gnueabihf
sudo apt install g++-arm-linux-gnueabihf

Now you are ready to cross compile on your PC all the source available
for the Acme Boards based on Microchip MPUs.

###Try the cross C compiler

Let’s try to cross compile a Hello World example in C and running it
on an Acme board.

This is the example:

#include "stdio.h"
 
int main(void) {
  printf("Hello world!n");
  return 0;
}

Compile it typing:

arm-linux-gnueabi-gcc hello.c -o hello

As you can see we are using the ARM version of gcc just installed on
your PC. It will generate an executable file for your Linux board.

Copy the executable file on the board via ssh:

scp hello root@[your_board_ip]:/root

Then open a command session on your board and run the example:

./hello
Hello world!

###Try the cross C++ compiler

Let’s try to cross compile a Hello World example in C++ and running it
on an Acme board.

This is the example:

#include "iostream"
 
using namespace std;
 
int main(int argc, char *argv[]) {
    cout << "Hello world!" << endl;
    return 0;
}

Compile it typing:

arm-linux-gnueabi-g++ hello.cc -o hello

As you can see we are using the ARM version of gcc just installed on
your PC. It will generate an executable file for your Linux board.

Copy the executable file on the board via ssh:

scp hello root@[your_board_ip]:/root

Then open a command session on your board and run the example:

./hello
Hello world!

All of the packages in this tutorial are also in the default Ubuntu 14.04 repositories.
