Install the Arm-Linux cross compiler correctly in four steps

Have you ever metRedHat5.0 install Arm-Linux crossoverCompilerIs there always a problem of installation errors? The author of this article has also encountered this situation, but after some exploration, he has successfully solved the above problems. Let's take a look!

The correct method for installing the Arm-Linux cross compiler is as follows:

First, I used the cross-Editor eabi-4.3.3_embedsky_20100610.tar.bz2,

1. First, create a directory for storing the cross compiler. The absolute path of the directory I created is/opt/TQ (TQ is the directory I created)

2. Decompress eabi-4.3.3_embedsky_20100610.tar.bz2:

tar xjvf  EABI-4.3.3_EmbedSky_20100610.tar.bz2

After the file is decompressed, two directories are generated in the TQ Directory: opt, usr;

3. Add environment variables:

Add in/etc/profile

# Path manipulationif [ "$EUID" = "0" ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
pathmunge /opt/TQ/opt/EmbedSky/4.3.3/bin/
fi

Source/etc/profile takes effect after adding;

4. Run the following command on the console:

cp     /opt/TQ/opt/EmbedSky/4.3.3/bin    /usr/local/arm

Conclusion: The following error occurs when steps 1 and 2 are missing:

arm-none-linux-gnueabi-gcc: error trying to exec 'cc1': execvp: No such file or directory

Experience: Use the following command to decompress the package:

tar xjvf  EABI-4.3.3_EmbedSky_20100610.tar.bz2   -C/

You can skip step 4.

-C/: Decompress the package to the specified directory. The root directory is specified here. Because the directory structure inside the package contains usr/local/arm, therefore, to decompress the package to the root directory is to decompress the file to the/usr/local/arm folder.
