After installing the WP77XX SDK via legato-spm, I’m getting build errors, even for the samples. It seems to be using my host gcc, rather than target gcc. ``` alex@devspace:~$ legato-spm -i -m WP77XX Browsing repository content Browsing repository Fetching content.jar (3 KB - 18 KB/s) Fetching artifacts.jar (1 KB - 5 KB/s) Fetching artifacts.jar (1 KB - 5 KB/s) ========== Install pending packages ========== Found 0 update site ========== Install packages ========== Do you accept the license?

can you try with LEAF+VSCODE? > **[Legato Plugin for VSCode - Legato Docs](https://docs.legato.io/latest/tools_vsCode.html)** > > legato™ is an open source Linux-based embedded platform designed to simplify connected IoT application development ---

Since this is a remote login to a dev server, no. Just for fun, I attempted to locally on my desktop, and even though the Legato plugin is installed in vsCode (and I restarted the app for good measure), I don’t see any “Leaf” menu anywhere, even after opening an active Leaf Workspace folder according to the instructions. ---

Ok, so the problem with vsCode was that I didn’t notice the new “leaf” tab on the left. Still haven’t really used it since it’s not particularly discoverable, but… I did, get leaf working. What was not clear, anywhere, is that legato-spm is no longer used, and that leaf is a replacement, not just a supplement. Removing everything installed by legato-spm did fix this.
