Right after cross-tools, a compiler-metadata.mk file is created that stores all of the bsd.compiler.mk metadata. It is then read in with a fail-safe during installworld time. The file is explicitly removed when invoking cross-tools to ensure that a stale file is not left around from odd manual 'make _cross-tools' -> 'make installworld' invocations. This fixes several issues: - With WITH_SYSTEM_COMPILER (default yes on head and no on releng/11.0): If you build on a system where the bootstrap compiler does not build due to the host compiler matching the in-tree one, but then installworld on another system where that logic fails (a bootstrap compiler is needed), the installworld immediately fails with: sh: cc: not found Note that fixing this logic may then hit a case where a rebuild is attempted in installworld. Normally cc would be ran with 'CFLAGS+=ERROR-tried-to-rebuild-during-make-install' to cause an error such as: cc: error: no such file or directory: 'ERROR-tried-to-rebuild-during-make-install' However, now it will just fail with the 'cc: not found' error. Inspection of the compile line will show 'ERROR-tried-to-rebuild-during-make-install'; It's not useful to set CC to anything other than 'cc' during install as it is more helpful to see the attempted compile rather than some other bogus error. - This now avoids running bsd.compiler.mk (cc executions) even more during installworld. There are compiler-dependent SUBDIR in the tree which required having a compiler during install. There is at least 1 case where CC is still executed in the install, such as from a LOOKUP!= in secure/lib/libcrypto/Makefile.inc checking for 'vzeroall' support. This is not significant for installworld as the lookup has a fallback (and hides its error) and only modifies CFLAGS, thus it's not worth fixing.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel
and installkernel
targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel
and installkernel
targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
devices, not just those commonly used.
