builds and installs only what is necessary to link and run binaries, when
the library is not externally useable.
- NOPIC: Create and link against a static library.
- PIC: Create, link against, and install a shared object.
- PIC+LDSTATIC: Create and link against a static library; create and
install a shared object.
tech-toolchain for a very detailed explanation of this. In short, add
a .y.h rule identical to the .y.c rule and make the .y.c rule rename
the .h file; also, clean the .h file in CLEANFILES.
* new bsd.own.mk variable OBJECT_FMT with values "a.out" or "ELF".
* use OBJECT_FMT in Makefile tests that depend on toolchain.
* Add new bsd.own.mk variable NOSHLIB that, if set indicates a given
port doesnt yet do shared libraries. Set on powerpc.
* Document new feature-test variables in src/share/mk/bsd.README.
Tested on i386, mips, fakedup Alpha environment.
- sys.mk:
add ${OBJC} and ${OBJCFLAGS} (equivalent to ${CC} and
${CFLAGS} respectively), and ${COMPILE.m} and ${LINK.m} rules
- bsd.sys.mk:
add .m, .m.o, and .m.ln rules (as per the C rules in sys.mk).
it's here, rather than in sys.mk, because `.m' isn't
exclusively used for Objective C files.
- bsd.lib.mk:
add .m.o, .m.po, .m.so, and .m.ln rules (as per C)
* Allow bsd.man.mk to be included separately.
* Always include bsd.own.mk and bsd.obj.mk.
* Include bsd.man.mk and bsd.nls.mk even if NOMAN or NONLS; just turn off
building of the affected files instead.
* Require bsd.subdir.mk to be included explicitly.
(Will make appropriate changes to Makefiles shortly.)
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.
support the two different incompatible rules for build .so files from
.S source on both NetBSD and binutils toolchains:
${CPP} | ${AS} for syscalls
${CC} for non-syscalls
for which the different toolchains's ${AS} requires diffferent flags.
