This chapter shows how to compile and install a minimal Linux system. This system will contain just enough tools to start constructing the final CLFS system in Installing Basic System Software and allow a working environment with more user convenience than a minimum environment would.
The tools in this chapter are cross-compiled using the toolchain in
/cross-tools and will be installed
under the ${CLFS}/tools directory to
keep them separate from the files installed in Installing
Basic System Software and the host production directories. Since
the packages compiled here are temporary, we do not want them to
pollute the soon-to-be CLFS system.
Check one last time that the CLFS
environment variable is set up properly:
echo ${CLFS}
Make sure the output shows the path to the CLFS partition's mount
point, which is /mnt/clfs, using our
example.
During this section of the build you will see several WARNING messages like the one below. It is safe to ignore these messages.
configure: WARNING: If you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used.
