In this lesson, you will go through the process of configuring the Toradex Software Development Kit (SDK) for cross-compilation of C/C++ code to the ARM architecture, which uses the GNU C Compiler (GCC).
In this lesson you will:
Download the Toradex SDK to the home directory of your computer.
Download the 64-bit SDK from here.
It includes the cross toolchain for building applications on the host machine, as well as the target root filesystem with development headers.
Warning: Make sure to use a matching SDK version (e.g. for Linux version 2.7, download SDK version 2.7). All available SDK versions are found here.
Open the Linux terminal and go to the home directory. Install the SDK using the following commands. Use the default installation directory:
Note: This assumes that you downloaded your toolchain file in your home folder! Make sure to check where you downloaded the toolchain file and navigate accordingly using the cd command.
user@host:~$ cduser@host:~$ chmod +x angstrom-glibc-x86_64-armv7at2hf-neon-v2017.12-toolchain.shuser@host:~$ ./angstrom-glibc-x86_64-armv7at2hf-neon-v2017.12-toolchain.shAngstrom SDK installer version nodistro.0=========================================Enter target directory for SDK (default: /usr/local/oecore-x86_64):You are about to install the SDK to "/usr/local/oecore-x86_64". Proceed[Y/n]? y
Note: The lib paths are hard-coded in the moment of the installation-extraction. If you use a custom directory path and by any circumstance, you need to move it to another location afterward, make sure to re-install the SDK.
Export the variables for cross-compilation.
Attention: You must execute this step every time you open a new terminal window or tab for cross-compilation.
Warning: In the command above, notice that there is a dot and a space before the path to the script.
