Troubleshooting

Using the complete LLVM toolchain system wide in Gentoo is not standard. Knowledge on how to troubleshoot various Portage phase errors is important. The key phases are configuring, compiling, testing, and installing. Any one of these phases can fail when straying off the standard Gentoo configuration.

This page will cover how to troubleshoot and also document packages with problems. Some errors are not going to be universal since Gentoo is capable of being tailored to different uses. What may affect one machine might not affect another.
