From 089a168917244cc1512a1ae7bd60de1a4c08eba1 Mon Sep 17 00:00:00 2001 From: luigi Date: Wed, 4 Jan 2012 19:37:25 +0000 Subject: remove some stale options (such as running without /boot/loader) improve support for multi-arch and cross-arch builds, by adding a suffix to the kernel config file and build_directory. (cross builds not clean yet, a cross-built kernel boots but fails when starting /sbin/init) --- release/picobsd/build/Makefile.conf | 5 +- release/picobsd/build/picobsd | 122 +++++++++++++++--------------------- 2 files changed, 55 insertions(+), 72 deletions(-) (limited to 'release/picobsd') diff --git a/release/picobsd/build/Makefile.conf b/release/picobsd/build/Makefile.conf index 5234349..7340663 100644 --- a/release/picobsd/build/Makefile.conf +++ b/release/picobsd/build/Makefile.conf @@ -13,6 +13,7 @@ BINMAKE?=make SRC?=/usr/src CONFIG?=config MODULES?=-DNO_MODULES # do not build them as a default +KERNCONF ?= PICOBSD # caller will set MODULES to empty if modules are needed. # Indeed, it can be used to specify other Makefile options as well. @@ -45,10 +46,10 @@ ${COMPILE}: ${CONF}/${CONFFILE} (cd ${CONF}; ${CONFIG} -d ${COMPILE} ${CONFFILE}; \ cd ${COMPILE}; ${BINMAKE} KERNEL=kernel ${MODULES} depend ) -${CONF}/${CONFFILE}: PICOBSD +${CONF}/${CONFFILE}: ${KERNCONF} # -mkdir -p ${CONF} # XXX not needed yet. cp ${.OODATE} ${.TARGET} - if [ -f PICOBSD.hints ] ; then cp PICOBSD.hints ${CONF}/PICOBSD.hints ; fi + [ -f PICOBSD.hints ] && cp PICOBSD.hints ${CONF}/ # This part creates crunch1.conf and crunch.mk from crunch.conf ${BUILDDIR}/crunch.mk: ${BUILDDIR}/crunch1.conf diff --git a/release/picobsd/build/picobsd b/release/picobsd/build/picobsd index 2910f9f..76f4c99 100755 --- a/release/picobsd/build/picobsd +++ b/release/picobsd/build/picobsd @@ -105,11 +105,6 @@ set_defaults() { # no arguments EDITOR=${EDITOR:-vi} fd_size=${fd_size:-1440} - o_use_loader="yes" # use /boot/loader - # You should not change it unless you are really short - # of space, and your kernel is small enough that the - # bootblocks manage to load it. - o_all_in_mfs="yes" # put all files in mfs so you can boot # and run the image via diskless boot. o_clean="" # set if you want to clean prev.builds. @@ -179,7 +174,17 @@ create_includes_and_libraries2() { # opt_dir opt_target if [ -d "$1" ] ; then cd $1 ; ${BINMAKE} ${o_par} $2 # specific target, e.g. ld-elf.so else - ${BINMAKE} ${o_par} _+_= $no toolchain _includes _libraries + # export WITH_RESCUE=yes # build crunchide + # ${BINMAKE} ${o_par} _+_= $no toolchain _includes _libraries + ( + # eval export `cd ${SRC}; ${BINMAKE} -f Makefile.inc1 -V BMAKEENV` + eval "export XMAKE=\"`cd ${SRC}; make -f Makefile -V XMAKE`\"" + ${BINMAKE} ${o_par} _+_= $no toolchain + ) + eval export `cd ${SRC}; ${BINMAKE} -f Makefile.inc1 -V WMAKEENV` + ${BINMAKE} ${o_par} _+_= $no _includes _libraries + [ ${o_arch} != `uname -m` ] && \ + (cd ${l_objtree}; ln -s . ${o_arch}.${o_arch} || true ) fi ) } @@ -242,16 +247,19 @@ set_type() { # the_type the_site name="" # clear in case of errors for i in ${c_startdir}/${a} ${PICO_TREE}/${a} ; do log "set_type: checking $i" - [ -d $i -a -f $i/PICOBSD -a -f $i/crunch.conf ] || continue - set -- `cat $i/PICOBSD | \ + [ -d $i -a -f $i/crunch.conf ] || continue + # look for a kernel config file, privilege arch-specific + l_kernconf=$i/PICOBSD.${o_arch} + [ -f $l_kernconf ] || l_kernconf=$i/PICOBSD + [ -f $l_kernconf ] || continue + set -- `cat $l_kernconf | \ awk '/^#PicoBSD/ {print $2, $3, $4, $5, $6}'` [ x"$1" != "x" ] || continue - MFS_SIZE=$1 ; init_name=$2 - mfs_inodes=$3 ; fd_inodes=$4 + MFS_SIZE=$1 name=`(cd $i ; pwd) ` name=`basename $name` MY_TREE=$i - BUILDDIR=${c_startdir}/build_dir-${name} + BUILDDIR=${c_startdir}/build_dir-${name}-${o_arch} log "Matching file $name in $i" return ; done @@ -328,10 +336,7 @@ main_dialog() { K "edit Kernel config file" \ E "Edit crunch.conf file" \ S "MFS Size: ${MFS_SIZE}kB" \ - I "Init type: ${init_name}" \ F "Floppy size: ${fd_size}kB" \ - M "MFS bytes per inode: ${mfs_inodes}" \ - U "UFS bytes per inode: ${fd_inodes}" \ $ "Site-info: ${SITE}" \ Q "Quit" \ 2> ${c_reply} @@ -349,12 +354,6 @@ main_dialog() { { dialog --menu "Setup the type of configuration" 12 70 5 $l \ 2> ${c_reply} && set_type "`cat ${c_reply}`" ${SITE} ; } || true ;; - I) - { dialog --menu "Choose your init(8) program" \ - 10 70 2 init "Standard init (requires getty)" \ - oinit "small init from TinyWare" 2> ${c_reply} \ - && init_name=`cat ${c_reply}` ; } || true - ;; K) ${EDITOR} ${MY_TREE}/PICOBSD ;; @@ -386,20 +385,6 @@ this as small as possible.
