  - Can you give us a reference to the project that you are running against this tool? [e.g. No if it's a close source project, but in case of an open source project a link to the sources could be nice.]
  - What build tools this project is using? [e.g. GNU make wtih `configure` script]
  - What architecture you are trying to compile for? [e.g. cross compiling]
- - Could you attach build logs? If you can re-run the command which failed (e.g. `bear -- make`) with extra verbose log switches (e.g. `bear --verbose -- make`) and send the output of it, that would help a lot.
