. if the layout of virtual address regions as returned
by mmap() without a location hint changes, ld.so could
trip itself up (under minix). this change allocates
the full size it needs for every object that's loaded
so that if that succeeds, it's sure there's virtual address
space for the whole thing no matter what other bits happen
to be there already.
. this fix exposed a bug in the test; at atexit() execution
time the loaded object is unmapped, so that part of the
test is removed.
This decreases external dependencies for crosscompilation. Note that
these libraries are not built nor used by Minix itself.
Furthermore, the shell scripts that download the tarballs for these
libraries, gcc, binutils, and gmake now also support curl in addition
to wget.
The rc script manually parses /etc/fstab to mount all file systems.
To do that it needs /bin/sed which does not exist anymore. mount(8)
now supports the -a flag which causes it to mount all file systems
listed in /etc/fstab except for '/'. File systems marked with 'noauto'
are skipped.
This commit finalizes support for cross compilation. The tools
directory are all links to the actual tools and are built on the
host system to build Minix. build.sh is the work horse that takes
care of all environment settings. It's slightly adjusted for Minix.
The /usr/src/Makefile has additional targets needed for cross
compilation.
mtree is only used for cross compilation at this point. Also, the
required patches to make it compile on Minix cripple it probably
enough to make it unusable anyway.
They are used as build tools for cross compilation. This import does
not include the full distribution. Rather, it sports a shell script
that will download and patch the distribution when compiled from
/usr/src/tools (yet to be committed). This part of the source tree is
only necessary for cross compilation. It's not used or compiled for
native builds.
. Some Makefile fixes to automatically differentiate between a normal
compilation and cross-compilation. Also, build compressed images.
. Harmonize ramdisk rc scripts for normal use case and ext2 ramdisk.
. ext2_ramdisk filesystem prototype fixes.
