Establishing a cross-compilation environment - mini2440 development board

Ubuntu 64-bit direct installation of arm-linux-gcc-4.4.3 will cause an error

~$ sudo apt-get install ia32-libs install some 32-bit libraries```

Development environment: Fedora9 32-bit

Note: When vmbox bridges the network, you need to set a static IP, otherwise you will not be able to connect to the Internet

Step 1: Install arm-linux-gcc-4.4.3

Copy arm-linux-gcc-4.4.3.tgz in the linux directory of the CD to a directory such as tmp, and then

Enter the directory and execute the decompression command:

#cd /tmp

tar -xzvf arm-linux-gcc-4.4.3.tar.gz -C /

Note: There is a space after C, and C is capitalized. It is the first letter of the English word "Change".

Here it means changing the directory.

Execute this command to install arm-linux-gcc to the specified directory, as shown in the following figure (here is the opt/FriendlyARM/toolchain/4.4.3 directory):

Step 2: Add the compiler path to the system environment variable

Edit the /root/.bashrc file and add the following line to the last line:

export PATH=$PATH:/opt/FriendlyARM/toolschain/4.4.3/bin

refresh

source /root/.bashrc

Or add in the /etc/profile file to set the global environment variables

sudo vim /etc/profile

source /etc/profile

Note: Under the 64-bit operating system, you also need to install a 32-bit support library (because the arm-linux-gcc tool is 32-bit). The installation command is apt install lib32ncurses5 lib32z1

Execute `arm-linux-gcc -v, the following indicates that the installation is successful:

Step 3: Unzip and install the source code

Create working directory /opt/FriendlyARM/mini2440

Execute mkdir –p /opt/FriendlyARM/mini2440 in the command line

cd /opt/FriendlyARM/mini2440

Create a temporary directory /tmp/linux in the /tmp directory of the Fedora9 system

#mkdir /tmp/linux

Copy all the files in the linux directory on the CD to the /tmp/linux directory

Unzip each compressed package.

example:

Unzip and install the Linux kernel source code

Execute in the working directory /opt/FriendlyARM/mini2440:

#cd /opt/FriendlyARM/mini2440

#tar xvzf /tmp/linux/linux-2.6.32.2-mini2440*gz

The linux-2.6.32.2 directory will be created, which contains the complete Linux-2.6.32.2 kernel source code
