This is useful for cross-compilation. Detailed +instructions can be found in the +[user settings part of the manual](doc/user-settings.md#specifying-the-final-stage-to-build). + Troubleshooting --------------- Here are a few simple suggestions that might help you fix the build: - + * Hadrian is occasionally broken by changes in GHC. If this happens, you might want to switch to an earlier GHC commit. - + * If Hadrian fails with the message `Configuration file hadrian/cfg/system.config is missing`, you have probably forgotten to pass the `--configure` flag during the first build. - + * If you need help in debugging Hadrian, read the [wiki](https://github.com/snowleopard/hadrian/wiki) and Shake's [debugging tutorial](https://shakebuild.com/debugging). |
