Bootstrapping steps: 1. Modify env.sh to accept the uname output. 1. Modify header.kmk to accept and correctly configure the platform / target OS. 1. Run kBuild/env.sh to configure the kBuild environment. 1. 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. 1. Configure and build GNU sed: 1. Go to the src/sed directory. 1. Run aclocal, autoconf and automake in src/sed if needed. 1. Create and enter src/sed/obj. 1. Run ../configure --disable-nls. 1. Run make 1. Copy config.h to src/sed/config.h.$BUILD_TARGET (or similar, see Makefile.kmk). 1. Copy sed/sed[.exe] to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/kmk_sed[.exe]. 1. Configure and build plain GNU Make: 1. Run aclocal, autoconf and automake in src/gmake if needed. 1. Create and enter src/gmake/obj. 1. Run ../configure --disable-nls. 1. Run make 1. Copy config.h to src/gmake/config.h.$BUILD_TARGET (or similar, see Makefile.kmk). Append empty string #defines for LOCALEDIR, LIBDIR, INCLUDEDIR and ALIASPATH (see config.h.linux). 1. We've now got our own make binary which will be used further down. 1. Build src/gmake using the GNU Make we just made: 1. Go to the src/gmake directory. 1. obj/make -f Makefile.kmk 1. When it breaks fix the compiler / linker error and redo the previous step. 1. Copy out/$BUILD_TARGET.$BUILD_TARGET_ARCH/release/kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/ to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/. 1. 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). 1. Go to the root. 1. kmk BUILD_TYPE=release rebuild 1. Fix build breaks and repeat the previous step. 1. Copy out/$BUILD_TARGET.$BUILD_TARGET_ARCH/release/kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/ to kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/. 1. 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. == New Bootstrapping Steps (src/gmakenew) == 1. Modify env.sh to accept the uname output. A kBuild BUILD_TARGET / BUILD_PLATFORM OS name must be decided upon at this point. If the architecture and/or processor is new to kBuild, new (unique) names need to be found here as well. 1. Modify header.kmk to accept and correctly configure the platform / target OS. 1. Run kBuild/env.sh to configure the kBuild environment. 1. Port and bootstrap kmk. The bootstrap kmk build is made using the GNU automake/autoconf setup of GNU make. Which means that the initial port of the kmk code has to be done in that environment. Since porting isn't a common day thing, nor is bootstrapping this is just something we have to live with. 1. The source is derived from the GNU make CVS and not a GNU make tarball. This means all the auto-stuff has to be created first. Run this from the src/gmake directory: {{{ autoreconf -i }}} For solving problems check out the autoreconf manual page and README.cvs. 1. Create a subdirectory {{{obj}}} for to do the build within. This avoids confusion later and simplifies cleanup. Enter the directory. 1. Run configure: {{{ ../configure }}} 1. Build it: {{{ make }}} Don't expect it to build on the first try on a new platform. Fix build errors and repeat until success or you give up in frustration... 1. Copy (or symlink) the resulting {{{kmk}}} to {{{kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/}}}. You may have to create this directory first. 1. The kmk bootstrapping is now done (unless of course, bugs in the port needs addressing). 1. Copy or symlink a bournshell compatible shell (ash is preferred) to {{{kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/kmk_ash}}}. {{{/bin/sh}}} or {{{/bin/bash}}} is usually a good choice. 1. Configure/Port and build the kmk, ash, sed, and kDep* (all found in source) using the bootstrap kmk. It's recommended to take one directory at a time and start with kmk since that's almost done now. The job that's required for each directory is roughly this: 1. Check if anything special is required in Makefile.kmk for your OS. 1. If it's a autoconf based tool run configure to (re)generate the config.h for your OS. These are usually cached as {{{config.h.$(BUILD_TARGET)}}} files. Note. You might wish to check if it builds and checks out cleanly in the autoconf/automake framework. ''Applies to sed and kmk/gmake.'' 1. Try build: {{{ kmk }}} Address build errors (and warnings) until it builds successfully. 1. If it's a autoconf/automake based tool and it got a testharness/suite, it is recommended to test the binary you've just built in it. ''Applies to sed and to some degree kmk/gmake.'' 1. Copy the resulting binary/binaries to {{{kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/}}}. 1. Move on to the next tool. 1. When everything builds and you've copied the new binaries to the kBuild/bin/x.y location, it's time to rebuild everything using the new binaries. 1. Remove the {{{out/}}} directory found in the root of the kBuild tree. 1. Run {{{kmk}}} from the root. 1. Replace binaries in {{{kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/}}} with the new ones from {{{out/$BUILD_TARGET.$BUILD_TARGET_ARCH/$BUILD_TYPE/kBuild/bin/$BUILD_TARGET.$BUILD_TARGET_ARCH/}}}. 1. It doesn't hurt to repeat this sequence once more. 1. Create patches and submit to bird along with a release build of the tools binaries. == 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.
