Bootstrapping steps:

1. Modify env.sh to accept the uname output.
2. Modify header.kmk to accept and correctly configure the platform / target OS.
3. Run kBuild/env.sh to configure the kBuild environment.
4. Copy unix like tools from you system to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/. kBuild requires all ash (bash is recommended), cat, cp, echo, install, ln, mkdir, mv, rm, rmdir and (gnu) sed. The kBuild copies must be prefixed with kmk_. These tools will be replaced later in the bootstrapping.
5. Configure and build GNU sed:
   1. Go to the src/sed directory.
   2. Run aclocal, autoconf and automake in src/sed if needed.
   3. Create and enter src/sed/obj.
   4. Run ../configure --disable-nls.
   5. Run make
   6. Copy config.h to src/sed/config.h.$BUILD_TARGET (or similar, see Makefile.kmk).
   7. Copy sed/sed[.exe] to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/kmk_sed[.exe].
6. Configure and build plain GNU Make:
   1. Run aclocal, autoconf and automake in src/gmake if needed.
   2. Create and enter src/gmake/obj.
   3. Run ../configure --disable-nls.
   4. Run make
   5. Copy config.h to src/gmake/config.h.$BUILD_TARGET (or similar, see Makefile.kmk). Append empty string #defines for LOCALEDIR, LIBDIR, INCLUDEDIR and ALIASPATH (see config.h.linux).
   6. We've now got our own make binary which will be used further down.
7. Build src/gmake using the GNU Make we just made:
   1. Go to the src/gmake directory.
   2. obj/make -f Makefile.kmk
   3. When it breaks fix the compiler / linker error and redo the previous step.
   4. Copy out/$BUILD_TARGET.$BUILD_TARGET_ARCH/release/kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/ to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/.
8. Rebuild everything using kmk (which should now be in the path):
   1. Run kBuild/env.sh (or continue in the shell from the previous step).
   2. Go to the root.
   3. kmk BUILD_TYPE=release rebuild
   4. Fix build breaks and repeat the previous step.
   5. Copy out/$BUILD_TARGET.$BUILD_TARGET_ARCH/release/kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/ to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/.
9. Add and commit the changes (including the binaries).

Note! On GNU/Linux make sure you have a real yacc install. GNU bison is not sufficiently compatible with yacc to make src/ash (from NetBSD) happy.

Trouble Shooting

• On Solaris cp doesn't like being called kmk_cp. So, when building src/gmake for the first time, it might be necessary to add CP=/bin/cp to the make command line.
• The sed and GNU make configure scripts might not like the system sed. Try find a GNU sed binary or bootstrap it yourself. Copy you sed program to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/ (without any prefix) and it'll be used instead of the system sed.
• Use a real YACC when compiling ash. GNU bison will not work (yyerrstatus undeclared error). You can add YACC=/path/to/real/yacc to the kmk command line if it's not in the PATH.
