the environment:
CPUFLAGS Additional flags to the compiler/assembler to select
CPU instruction set options, CPU tuning options, etc.
Since CPUFLAGS is not implicitly set by any part of the make infrastructure,
it is safe to set in mk.conf, unlike COPTS or DBG.
* Unnecessarily causes lib/librpcsvc (etc) to be rebuilt every time
rpcgen is updated.
* No other "generated" file (.l, .y, ...) depends upon its tool
like this
* As <bsd.own.mk> wasn't being pulled in, the tools/ version
wasn't being used, so a lot of times the dependency was wrong.
Fixes [toolchain/11568] by Bernd Ernesti.
Note: this is the first tool using a "TOOL_" prefix in the make(1) variable;
other similar "non-standard" variable names will be converted in the future.
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.
The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.
This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile. Remove the now-unnecessary .keep_me files
whilst here.
Per lengthy discussion with Andrew Brown.
- add '-D ${DESTDIR}' to INSTPRIV, so install(8) removes the leading
${DESTDIR} from the metalogged path
- provide ${METADB.add} variable (for "${CAT} -l >> ${METALOG}"), to make
it easier to replace manual metalog manipulation in the future.
- with manual metalog additions, don't add the leading ${DESTDIR} in the path
- in maketars, use "mtree -C ..." instead of
"mtree -D ... | sed -e 's,\(.*\) \(\..*\),\2 \1,";
Benefits:
- maketars "Parsing METALOG" step speeds up from 29 seconds to 1.2 seconds
on a P3-600.
(This also benefits "make installworld" at the top level.)
- ${DESTDIR}/METALOG is easier to read without the leading "${DESTDIR}"
on all the pathnames, and it's smaller as well.
Fixes a problem found by Andrew Brown where programs outside of the NetBSD
src that use the /usr/share/mk framework (such as pkgsrc/pkgtools/digest)
couldn't be installed if /usr/src/etc wasn't present.
