I guess there is some miscommunication. I will expand a bit.
For building apps on nodejs/electron, the devs don’t have to build the safe_app rust libraries themselves. The safe-app-nodjes plugin would download the native dependency based on the platform on which it is being installed. The dev has to include the safe_app-nodejs dependency in the package.json file (eg, refer email app). Few of the devs were trying to build the libraries themselves and had raised few issues, hence we thought of clarifying it again in the post to make it clear. However, the safe_browser must be built manually following the Readme instructions as of now.
Moving forward, we are planning to release the browser with the mock routing version. We will build the safe_browser binaries for desktop platforms and tag it in the github releases. As a start, we will build the latest version of the safe_browser with mock routing and release it tomorrow.
Even when the test network is ready, we will release two versions of the safe_browser (actual and mock network).
