**@nburkitt, it looks like the modem’s Linux does not match with the toolchain version with which your mangoH was compiled with. With every release, we provide modem firmware, Linux and Legato and a toolchain to cross compile your applications with. All components can be changed, but the application should be compiled with the toolchain that matches the Linux component installed on the modem.** **I checked with R12 and I was able to install mangOH successfully. I’ve detailed the steps below. I’m using a new tool called “Leaf” that pulls in all the required components for a specific release. Leaf installation directions are at [https://docs.legato.io/latest/toolsLeaf.html](https://docs.legato.io/latest/toolsLeaf.html). I used a PC with Ubuntu 18.04 X86 with all latest updates as my build machine. VBox will also work.** **Once you install Leaf, please follow the below steps (my workspace is “legatoWorkSpace”). I’ve truncated command responses and I picked R12 stable package and so my profile name for use with Leaf is "WP76\_R12\_Stable"** _a:legatoWorkSpace$ leaf search -t wp76xx -t stable_ ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/a/a3058576ac6e5c712c9df83dcc841bdf0871c13f.png) _a:legatoWorkSpace$ leaf setup WP76\_R12\_Stable -p swi-wp76\_3.0.0_ _[7/7] Installing swi-wp76\_3.0.0_ _Run install steps for swi-wp76\_3.0.0._ **Clone mangOH Repo** _a:legatoWorkSpace$ git clone --recursive git://github.com/mangOH/mangOH_ _a:legatoWorkSpace$ cd mangOH/_ **Start a shell in your selected profile to compile mangOH.
