1.123     jmc         3: This file (UPDATING) is intended to be a brief reference to recent
                      4: changes that might cause problems in the build process, and a guide for
                      5: what to do if something doesn't work.
1.1       abs         6:
1.123     jmc         7: For a more detailed description of the recommended way to build NetBSD
                      8: using build.sh, see the BUILDING file.
                      9:
                     10: Note that much of the advice in this UPDATING file was written before
                     11: build.sh existed.  Nevertheless, the advice here may be useful for
                     12: working around specific problems with build.sh.

                     32:        changed to indicate that our libc has ssp support built-in and
                     33:        does not depend on -lssp and -lssp-nonshared. You'll need to
                     34:        make clean in src/tools/gcc first to rebuild the compiler.

                     42:        withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC

                     48:        if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed

                     59:        (sys/arch/i386/conf/kern.ldscript*) were changed to set the

                     61:        (like Grub). If you use a linker (ld) older than from 2006/04/17, it
1.147     christos   62:        will be unable to link the kernel because of a bug and ld will fail
                     63:        with an error like:

                     66:        You need to update at least src/gnu/dist/binutils/ld and recompile
                     67:        and install the linker. If using the build.sh script, the easiest
                     68:        way is with a "build.sh tools" command, with any other options
                     69:        that you use normally. When using build.sh, the linker binary is
                     70:        installed as ${TOOLDIR}/bin/i386--netbsdelf-ld.

                     75:        you need to update ofwboot. After a full build, just copy
                     76:        /usr/mdec/ofwboot to /, or do a rebuild of

                     95:        modified to emit the new data structures.
