Linux From Scratch - Version 7.0
31
Note
Experience has shown that there is little to be gained from running the test suites in Chapter 5. There can
be no escaping the fact that the host system always exerts some influence on the tests in that chapter, often
causing inexplicable failures. Because the tools built in Chapter 5 are temporary and eventually discarded,
we do not recommend running the test suites in Chapter 5 for the average reader. The instructions for
running those test suites are provided for the benefit of testers and developers, but they are strictly optional.
A common issue with running the test suites for Binutils and GCC is running out of pseudo terminals (PTYs). This
can result in a high number of failing tests. This may happen for several reasons, but the most likely cause is that the
host system does not have the devpts file system set up correctly. This issue is discussed in greater detail at http://
www.linuxfromscratch.org//lfs/faq.html#no-ptys.
Sometimes package test suites will fail, but for reasons which the developers are aware of and have deemed non-
critical. Consult the logs located at http://www.linuxfromscratch.org/lfs/build-logs/7.0/ to verify whether or not these
failures are expected. This site is valid for all tests throughout this book.
