I built chromium for Windows 10, but crashpad didn't seem to build in it, because running chrome --enable-crashpad doesn't create the crashpad_handler process. On the other hand I have separately built crashpad, but it is not clear how to synchronize it with Chromium. Could you please tell me how to build crashpad directly inside chromium, preferably without re-building chromium!
You don't have to build crashpad for Chromium, it's built when compiling Chromium and runs with Chromium. But crash reporting will be disabled for Chromium builds which you can check if you goto: chrome://crashes/ URL. You can check if crashpad is running or not by crashing the current renderer process. Open a new tab and crash the current renderer process by typing the following URL:
chrome://crash/
You should see Aww snap message. So that basically means, crashpad is running.
