                      3: This file is intended to be a brief introduction to the build
                      4: process and a reference on what to do if something doesn't work.

        !            12:        The mk.conf(5) variable SYS_INCLUDE has been deprecated,
        !            13:        including the optional "SYS_INCLUDE=symlinks" support.
        !            14:        All header files, including <sys/*.h> are copied into
        !            15:        /usr/include.

                     17: 20021121:
                     18:        The C run-time support files crtbegin.o and crtend.o
                     19:        (and their companions crtbeginS.o and crtendS.o) were
                     20:        split up, with new crti.o and crtn.o files resulting.
                     21:        This means that libtool needs to be rebuilt once the
                     22:        new libraries are installed.  The process of rebuilding
                     23:        libtool will cause it to automatically notice the new
                     24:        required files, but it *must* be rebuilt in order to
                     25:        do this.
                     26:
                     27:        An out-of-date libtool will result in shared libraries
                     28:        which lack _init() and _fini() routines, which means that
                     29:        their global contructors/destructors will not be invoked.

                     31: 20021121:
                     32:        A bug related to how ARM ELF objects were tagged has been
                     33:        corrected.
                     34:
                     35:        NetBSD ARM ELF uses the soft-VFP floating point model by
                     36:        default.  However, the assembler lacked support for marking
                     37:        objects as using the VFP floating point format, and the
                     38:        compiler was no properly passing the flag indicating "soft-VFP"
                     39:        to the assembler.
                     40:
                     41:        Unfortunately, this means that the linker will now consider
                     42:        old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
                     43:        incompatible with new (properly marked) objects.
                     44:
                     45:        The problem will only manifest itself if you attempt to compile
                     46:        a new program using the fixed toolchain, and link that program
                     47:        against old libraries which do not have the proper "softvfp"
                     48:        markings.  ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
                     49:        WILL CONTINUE TO WORK PROPERLY.
                     50:
                     51:        The only work-around for the problem is to recompile all of
                     52:        the libraries on the system.  The easiest way to do this for
                     53:        system libraries is to install a binary snapshot; there are
                     54:        generally available on releng.netbsd.org.  Any packages you
                     55:        have installed which supply libraries will have to be recompiled
                     56:        if you wish to link new programs against those libraries.
                     57:
                     58:        If you have questions about this matter, please contact
                     59:        port-arm@netbsd.org.

                     62:        Systrace has been improved to support privilege elevation.
                     63:        Updating the kernel requires the userland part of systrace
                     64:        to be rebuild.

                     68:        dependencies on attributes, as well as other options.  Users
                     69:        must update and reinstall usr.sbin/config before building a new

                     74:        which is now used by the SCSI configuration description.  Users
1.71      wiz        75:        must update and reinstall usr.sbin/config before building a new

                     80:        framework.  Users must update and reinstall usr.sbin/config
                     81:        before building a new kernel.

                     85:        will need to add the option 'cpu* at mainbus?' to their configuration

                     94:        linker is installed into /libexec, and all programs in /bin
                     95:        and /sbin are dynamically linked.
                     96:        If you do not use "make build", you should ensure that
                     97:        you have the libraries and shared linker in the new locations,

                    107:                root ofan external toolchain (e.g. /usr/local/gnu).  This
                    108:                enables the cross-build framework even for TOOLCHAIN_MISSING
