3 sets of libraries are built now:
. ack: all libraries that ack can compile (/usr/lib/i386/)
. clang+elf: all libraries with minix headers (/usr/lib/)
. clang+elf: all libraries with netbsd headers (/usr/netbsd/)
Once everything can be compiled with netbsd libraries and headers, the
/usr/netbsd hierarchy will be obsolete and its libraries compiled with
netbsd headers will be installed in /usr/lib, and its headers
in /usr/include. (i.e. minix libc and current minix headers set
will be gone.)
To use the NetBSD libc system (libraries + headers) before
it is the default libc, see:
http://wiki.minix3.org/en/DevelopersGuide/UsingNetBSDCode
This wiki page also documents the maintenance of the patch
files of minix-specific changes to imported NetBSD code.
Changes in this commit:
. libsys: Add NBSD compilation and create a safe NBSD-based libc.
. Port rest of libraries (except libddekit) to new header system.
. Enable compilation of libddekit with new headers.
. Enable kernel compilation with new headers.
. Enable drivers compilation with new headers.
. Port legacy commands to new headers and libc.
. Port servers to new headers.
. Add <sys/sigcontext.h> in compat library.
. Remove dependency file in tree.
. Enable compilation of common/lib/libc/atomic in libsys
. Do not generate RCSID strings in libc.
. Temporarily disable zoneinfo as they are incompatible with NetBSD format
. obj-nbsd for .gitignore
. Procfs: use only integer arithmetic. (Antoine Leca)
. Increase ramdisk size to create NBSD-based images.
. Remove INCSYMLINKS handling hack.
. Add nbsd_include/sys/exec_elf.h
. Enable ELF compilation with NBSD libc.
. Add 'make nbsdsrc' in tools to download reference NetBSD sources.
. Automate minix-port.patch creation.
. Avoid using fstavfs() as it is *extremely* slow and unneeded.
. Set err() as PRIVATE to avoid name clash with libc.
. [NBSD] servers/vm: remove compilation warnings.
. u32 is not a long in NBSD headers.
. UPDATING info on netbsd hierarchy
. commands fixes for netbsd libc
patch to allow MINIX to boot from ext2.
To create a setup with MINIX on ext2, follow these steps:
- Assumptions:
- there exists a primary partition c0dApB with a MINIX installation
with GRUB support (/boot/image_latest exists on /dev/c0dApB)
- there exists a free primary partition c0dCpD
- Create an ext2 filesystem on c0dApB (from Linux, until Tthom
has ported mke2fs)
- Follow these steps (from a MINIX CD with ext2 support, another MINIX
installation (not c0dApB) or Linux >= 2.6.35):
mkdir /mnt/mfs /mnt/ext2
mount /dev/c0dApBs0 /mnt/mfs
mount /dev/c0dApBs1 /mnt/mfs/home
mount /dev/c0dApBs2 /mnt/mfs/usr
mount /dev/c0dCpD /mnt/ext2
synctree -f /mnt/mfs /mnt/ext2
echo root=/dev/c0dCpD > /mnt/ext2/etc/fstab
(note: no subpartitions used because that would confuse an unmodified
bootloader)
- Add the new MINIX installation to GRUB according to steps 7&8 in
