Hi, From your post I see that you are building httpServer sample application for WP85 Module. The latest release for WP85 is legato 16.10.3. 1. And the right way to get the release for a specific module would be to follow the below link to download the code using legato-spm. [https://source.sierrawireless.com/resources/airprime/software/legato\_application\_development\_kit\_linux/](https://source.sierrawireless.com/resources/airprime/software/legato_application_development_kit_linux/) 2. Follow the steps in “Configure Legato Environment” in below link to set the environment and tools path. [https://source.sierrawireless.com/resources/airprime/software/legato\_spm/](https://source.sierrawireless.com/resources/airprime/software/legato_spm/) 3. you can build the application the usual way . Regards, Vasantha ---
