'/usr/lib/PCBUSB' (no such file, not in dyld cache)`\n\nSince PCBUSB is not installed under _/usr/lib_, the PeakCAN plugin fails to load unless manual workarounds are applied.\n\nTo make the plugin work, I have to manually add a symlink to the bundled library:\n\n- either inside the app bundle, e.g.:\n\n`MyApp.app/Contents/Frameworks/libPCBUSB.dylib`\n\n- or next to the application binary during local development.\n\nAt the moment it is unclear what the correct long-term solution should be:\n\t•\tShould the PCBUSB driver installer be updated to place the dylib somewhere Qt can find it?\n\t•\tShould QtSerialBus / PeakCAN be patched to include /usr/local/lib or another search path?\n\nSummary\n\nThe PeakCAN plugin currently does not locate libPCBUSB.dylib in its default installation directory on macOS, which forces manual symlink creation during development and deployment.","author":{"url":"https://github.com/Pepe424","@type":"Person","name":"Pepe424"},"datePublished":"2025-12-11T14:15:48.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/25/PCBUSB-Library/issues/25"}
