Defaults to the directory determined by the _SRC_TOP_ logic (if != ""),
and the BSDSRCDIR.
NETBSDSRCDIR has been provided for use by the various NetBSD source
Makefiles to find the top of the NetBSD source tree, and isn't
affected by the inheritance properties of _SRC_TOP_, nor does it
have the magic BSDOBJDIR baggage that BSDSRCDIR is stuck with.
determined, since BSDSRCDIR's default of /usr/src might not exist and the
calculation of _SRC_TOP_OBJ_ would then generate a warning :-(.
_SRC_TOP_ can now == "" if make(1) (or a parent make(1)) was started
outside of the NetBSD source tree.
Now, if _SRC_TOP_ != "", BSDSRCDIR defaults to ${_SRC_TOP_} and
BSDOBJDIR defaults to the objdir of ${BSDSRCDIR}.
Failsafe defaults for BSDSRCDIR (/usr/src) and BSDOBJDIR (/usr/obj)
are provided later in the file.
This should result in a usable BSDSRCDIR default (i.e, _SRC_TOP_ if
running from within the source tree), with safe fallbacks as appropriate
(/usr/src, as always), meaning that BSDSRCDIR should be able to be used
instead of _SRC_TOP_ in the source tree, although I need to carefully
test this. *aaaiiiieeee!!!*. (Now I understand some of Todd's pain :)
make -V FILES
from being useful (and given that every other variable can be
extracted using make -V, the behaviour was unusually inconsistent
given that the original reason for clearing it doesn't seem to be
relevant anymore)
- use <bsd.prog.mk> instead of directly including <bsd.files.mk>

${BSDSRCDIR} if make(1) is running outside of the NetBSD source tree.
This should solve various issues, including building xsrc which uses

* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
of the infratsructure (libraries, support programs, etc.)
* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
building of support for using the corresponding API
in various libraries/programs that can use it.
As discussed on tech-toolchain.
Instead of:
install -m 600 [...]
ranlib -t [...]
chmod 444 [...]
use the newly added "-a" flag to install(1) to invoke ranlib ifndef UPDATE.
Should prevent unnecessary ranlib-ing of installed libraries with UPDATE
defined.
Per discussion with simonb.
round has been tested on Solaris/x86 and Linux hosts.
* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.
compiles. Based loosely on mkdep.old.compiler (so CSRG license copied),
but now uses just one rewrite (awk) process per cpp invocation and
determines the proper way to run cpp and awk via a "configure" script.
Use HOST_MKDEP in bsd.hostlib/hostprog.mk (defaulting to the old override
value of MKDEP), and give it a TOOLDIR equivalent in bsd.own.mk.
old one either. The "new toolchain" environment is closer to what we
want, however, for using the external toolchain currently required for
x86_64, so set USE_NEW_TOOLCHAIN for x86_64.
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
it (kernel and libc).
The current version of the gas assembler in the tree (2.11.2) already
defaults to generating object files for "-Av9 -64", supporting V9
instructions in ELF64 object format. "-Av9a" is only needed for specific
parts of the NetBSD base sources, and not for all third-party code.
Wrap assignments of various tools within USETOOLS_BINUTILS and
USETOOLS_GCC (names reflect the FSF packages the tools are provided
by), which default to "yes", for easy testing of different versions
of these packages.
