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:
user@host:~$ cduser@host:~$ chmod +x angstrom-glibc-x86_64-armv7at2hf-vfp-v2017.12-toolchain.shuser@host:~$ ./angstrom-glibc-x86_64-armv7at2hf-vfp-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
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.
