There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.
Changes in this commit:
. drop boot monitor -> allowing dropping ack support
. facility to copy ELF boot files to /boot so that old boot monitor
can still boot fairly easily, see UPDATING
. no more ack-format libraries -> single-case libraries
. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
. drop several ack toolchain commands, but not all support
commands (e.g. aal is gone but acksize is not yet).
. a few libc files moved to netbsd libc dir
. new /bin/date as minix date used code in libc/
. test compile fix
. harmonize includes
. /usr/lib is no longer special: without ack, /usr/lib plays no
kind of special bootstrapping role any more and bootstrapping
is done exclusively through packages, so releases depend even
less on the state of the machine making them now.
. rename nbsd_lib* to lib*
. reduce mtree
1. ack, a.out, minix headers (moved to /usr/include.ack),
minix libc
2. gcc/clang, elf, netbsd headers (moved to /usr/include),
netbsd libc (moved to /usr/lib)
So this obsoletes the /usr/netbsd hierarchy.
No special invocation for netbsd libc necessary - it's always used
for gcc/clang.
. Handle more compiler names, including most cross-compilers.
. Allows to use acd(1) and [whatever-]acc to designate ACK compiler.
. Do not abort (on COMPILER_TYPE not defined) if the compiler name
is not recognized.
and minor fixes:
. add ack/clean target to lib, 'unify' clean target
. add includes as library dependency
. mk: exclude warning options clang doesn't have in non-gcc
. set -e in lib/*.sh build files
. clang compile error circumvention (disable NOASSERTS for release builds)
This patch changes the system mk scripts to enable compilation
of programs using the BSD make system to compile with the new
libc.
In details, it does the following:
- it always defines the __MINIX make variable. This can be used,
in porting applications, to specialize Makefiles for Minix.
- If the environment variable NBSD is set to something different
than 'no' and if the compiler is not ack, set NBSD_LIBC to 'yes'.
This will set the destination lib directory to '/usr/netbsd/lib'
and set up CPPFLAGS and LDFLAGS to use new libc's includes and
library directory.
