Buildbot:Gentoo

This page is WIP! (don't expect these instructions to work, they only give a hint, how it should/could work...)

buildbot-slave (for interacting with spring's buildbot)

emerge dev-util/buildbot-slave
rc-update add buildslave default
nano /etc/conf.d/buildslave
useradd -s /bin/false -d $dir -m $username
buildslave create-slave $dir/buildslave springrts.com:7778 $username $passwd

Setup gentoo win32 buildslave

Note: boost and spring has to be compiled with the same compiler! If you get weird linker errors then this could be the cause!

tools required for compiling

emerge layman mercurial app-arch/p7zip-9.13 dev-util/cmake app-arch/zip wine crossdev app-portage/portage-utils
layman -a ohnobinki
echo "source /var/lib/layman/make.conf" >> /etc/portage/make.conf
CHOST=i686-mingw32 ROOT=/usr/i686-mingw32 emerge pthreads-win32
USE="openmp cxx -fortran" crossdev i686-mingw32 --env 'EXTRA_ECONF="--disable-sjlj-exceptions --with-dwarf --enable-gomp --disable-shared"'

for cgcreate (only needed for load balancing while building)

emerge dev-libs/libcgroup

Install i686-mingw32 compiler, then pthreads, then recompile i686-mingw32 with pthreads enabled

USE="openmp cxx -fortran" crossdev i686-mingw32 --env 'EXTRA_ECONF="--disable-sjlj-exceptions --with-dwarf"'
CHOST=i686-mingw32 ROOT=/usr/i686-mingw32 emerge -va pthreads-win32
USE="openmp cxx -fortran" crossdev i686-mingw32 --env 'EXTRA_ECONF="--disable-sjlj-exceptions --with-dwarf --disable-shared"'
emerge-wrapper --init

stuff that needs to be compiled native (not with mingw)

emerge ncurses cmake eselect eselect-boost
ACCEPT_KEYWORDS="~x86" emerge boost-build

build Spring + dependencies in MinGW

USE="minizip" emerge-i686-mingw32 sys-libs/zlib

1. USE="static"

emerge-i686-mingw32 app-arch/bzip2
USE="jpeg png opengl" emerge-i686-mingw32 devil

Setup static linux

create /etc/portage/package.use/spring-static-buildslave:

set compile flags on 64 bit gentoo

this is only required on 64bit gentoo!

if you don't add -fPIC you mostly will get errors like his:

relocation R_X86_64_32 against `a local symbol' can not be used when making a
shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../lib64/libfl.a: could not
read symbols: Bad value

/etc/portage/env/spring-static-buildslave:

CFLAGS="${CFLAGS} -fPIC"
CXXFLAGS="${CXXFLAGS} -fPIC"
LDFLAGS="${LDFLAGS} -fPIC"

/etc/portage/package.env/spring-static-buildslave:

sys-libs/zlib spring-static-buildslave
media-libs/devil spring-static-buildslave
dev-libs/boost spring-static-buildslave

install needed programs and libs

Emerge gcc-4.7.2

emerge -va =sys-devel/gcc-4.7.2

enable / use it

gcc-config x86_64-pc-linux-gnu-4.7.2
env-update && source /etc/profile

re-install required libs with changed use flags:

emerge -va sys-libs/zlib media-libs/devil dev-libs/boost media-libs/jpeg media-libs/libsdl \
media-libs/libvorbis media-libs/freetype media-libs/glew media-libs/libpng x11-libs/libXcursor \
app-arch/bzip2 x11-libs/libXdmcp x11-libs/libXrender x11-libs/libX11 x11-libs/libXfixes \
x11-libs/libxcb x11-libs/libXau

tune

use ld.gold for linking:

binutils-config --linker ld.gold

32 bit buildbot on a 64 bit slave

switch back to the standard linker as glibc doesn't compile with ld.gold if you get this error: "These critical programs are missing or too old: as ld"

binutils-config --linker ld.bfd
