A bit of progress :-) I compiled a shared library libwebview.so on Ubuntu with:
`` g++ webview.c -fPIC -shared -o libwebview.so `pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0` `` Before that, the gtk and webkit2 dev libraries should be installed with: `sudo apt install -y libwebkit2gtk-4.0-dev libgtk-3-dev` And if you don’t have gcc tools: `sudo apt install build-essential` I’ll see if I can figure it out for MacOS too. It appears that in Linux it is necessary to run the webview in separate thread, otherwise Pharo image gets blocked, so I have to slightly change the architecture (with threaded FFI as astares pointed out on Discord #ffi).
