2. Install toolchains
The SDK provides a cross-development toolchain and libraries tailored to the contents of a specific image.
Digi provides a pre-compiled C/C++ toolchain that matches the dey-image-qt image and contains the appropriate libraries for developing against that image.
The installed toolchain consists of several files and directories: an environment setup script, some configuration files, and host and target root file systems. For more information, see the Yocto Project Application Development and the Extensible Software Development Kit (eSDK) manual.
Digi Embedded Linux toolchain requires between 3 GB and 10 GB, depending on the platform.
Install a Digi toolchain
To install new Digi Embedded Yocto toolchains in your system, follow these steps:
-
Select Window > Preferences.
-
Select DEY Toolchains from the list on the left.
-
Click Browse and select the directory where you want to install the new toolchains, which must have write permissions. The default directory is
/opt/dey
. -
Click Download new toolchains. The Install new DEY toolchains dialog opens listing all the available toolchains to install.
-
Select the toolchains you want to install and click Install selected.
You can filter the available toolchains by platform using the platform combo box. -
The installation process starts and the dialog displays the installation status.
You can stop the installation process at any time by clicking Cancel. -
Once the process finishes, click Back to return to the available toolchains list and continue installing new toolchains, or click Close to close the dialog.
-
The installed toolchains table is updated with the new toolchains. Select a new default.
-
Click Apply and Close to save the changes.
The Close button closes the dialog and stops any active and pending toolchain installation. If you click the button and the install process has not yet finished, a popup message asks for confirmation. |
Install your custom toolchain
You must manually install any custom toolchains generated with Digi Embedded Yocto. To do this, follow these steps:
-
Copy the toolchain installer script to your host machine.
-
Give execution permission to the installer and install the toolchain on your host PC.
$ chmod +x dey-glibc-x86_64-core-image-base-cortexa7t2hf-neon-ccimx6ulstarter-toolchain-4.0-r6.sh $ ./dey-glibc-x86_64-core-image-base-cortexa7t2hf-neon-ccimx6ulstarter-toolchain-4.0-r6.sh
$ chmod +x dey-glibc-x86_64-dey-image-qt-x11-cortexa7t2hf-neon-ccimx6ulsbc-toolchain-4.0-r6.sh $ ./dey-glibc-x86_64-dey-image-qt-x11-cortexa7t2hf-neon-ccimx6ulsbc-toolchain-4.0-r6.sh
