[[!meta title="Bootstrap of the core-linux-eglibc Port"]]
Following is the planned procedure to bootstrap the core-linux-eglibc port from
a Debian GNU system. Debian's GNU toolchain for its amd64 architecture is used
to build a fake generic port named amd64-linux-eglibc.
This procedure assumes that Debian's build-essential package is installed, that
opkhelper 1.0.0 is installed, that genopkg.sh from opkhelper 1.0.0 has been run,
and that the following architecture table is present at
`/usr/local/share/opkhelper/archtab`:
# Map between distribution and build system architecture names.
#
# <Distribution arch> <GNU system type> <kbuild arch>
i686-linux-eglibc i686-pc-linux-gnu x86
amd64-linux-eglibc x86_64-pc-linux-gnu x86
core-linux-eglibc x86_64-pc-linux-gnu x86
k8-linux-eglibc x86_64-pc-linux-gnu x86
cortexa8-linux-eglibc arm-cortex_a8-linux-gnueabi arm
Subsequent ports like
[[i686-linux-eglibc|dev/ports/i686-linux-eglibc-bootstrap]] may simply be cross
built from the core-linux-eglibc port.
1. Build the following base system packages for amd64-linux-eglibc using
Debian's GNU toolchain:
* src:eglibc
* src:busybox
* src:linux-libre
* src:opkg
2. Build the following build essential packages for amd64-linux-eglibc using
Debian's GNU toolchain:
* src:binutils
* src:gmp
* src:mpfr
* src:mpc
* src:gcc-4.7
* src:gcc-defaults
* src:opkhelper-1.0
* src:build-essential
* src:fakeroot
Build src:binutils and src:gcc-4.7 with a core-linux-eglibc target.
3. Unpack the following essential binary packages into the target directory:
* libc.6
* libc-bin
* locales
* nscd
* zoneinfo
* busybox
* linux-libre
* libopkg.1
* opkg
4. Unpack the following build essential binary packages into the target
directory:
* libc.6-dev
* libc-dev-bin
* linux-libre-headers
* libgmp.10
* libgmp-dev
* libmpfr.4
* libmpfr-dev
* libmpc.2
* libmpc-dev
* gcc-4.7-base-core-linux-eglibc
* cpp-4.7-core-linux-eglibc
* gcc-4.7-core-linux-eglibc
* g++-4.7-core-linux-eglibc
* libgcc.1
* libstdc++.6
* libstdc++.6-4.7-dev
* cpp-core-linux-eglibc
* gcc-core-linux-eglibc
* g++-core-linux-eglibc
* opkhelper-1.0
* fakeroot
* build-essential-core-linux-eglibc
5. Unpack the following source binary packages into the target directory:
* eglibc-src
* busybox-src
* linux-libre-src
* opkg-src
* binutils-src
* gmp-src
* mpfr-src
* mpc-src
* gcc-4.7-src
* gcc-defaults-src
* opkhelper-1.0-src
* build-essential-src
6. Mount the proc and sysfs filesystems.
7. Run `/bin/sh` in an isolated environment with chroot.
8. Run the following command to rebuild every source package for
core-linux-eglibc:
# for src in /usr/src/*; do \
> cd "${src}"; \
> opkbuild -a core-linux-eglibc; \
> done
9. Exit ash and the isolated environment.
10. Collect from `usr/src` in the target directory the binary packages built for
core-linux-eglibc.
