Setup cross compile project with Eclipse¶

Install Eclipse on Ubuntu 16.4¶

First download Eclipse from Eclipse download <https://www.eclipse.org/downloads/> and java if not already installed (default-jre)

Install a debugger, if not already installed Eclipse IDE for C/C++ developers.

Optional Install a Remote System Explorer

Help->Install New Software...-> –All Available Sites– -> Mobile and Device Development or General Purpose Tools -> Remote System Explorer.

Build custom software development kit (sdk)¶

source layers/openembedded-core/oe-init-build-env

bitbake console-hostmobility-dev-image -c populate_sdk

There will be a file output angstrom-glibc-x86_64-armv7at2hf-neon-v2018.06-toolchain.sh under deploy/sdk (file name can change over time and depend on target machine).

Run that script file and follow those instructions.

Now there should be a sysroot folder, an environment setup file , an site-config and one version file under the install location.

Run environment-setup-armv7at2hf-neon-angstrom-linux-gnueabi.sh before you start Eclipse to include the environment variables to your project.

Setup hello_word application¶

Create a new C or C++ project. Select Empty Project or Hello World template and Cross GCC toolchain.

Then, in the toolbar, click Project and select Properties from the drop down menu.

Setup machine debugger¶

First Run->Debug configurations...->c/c++ remote application->add (right click).
