Its best to run a 64 bit gentoo, as x32 can be easily compiled, too.



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



on springrts.com in /home/buildbot/master/passwords.py a user and password must be added. this username is needed to connect the buildslave client to the master.



install buildbot on the slave:

<code><pre>

emerge dev-util/buildbot-slave

</pre></code>



add a local user which is used to build:

<code><pre>

useradd -s /bin/false -d /home/buildslave -m buildslave

</pre></code>



create the buildslave config

<code><pre>

buildslave create-slave /home/buildslave springrts.com:9989 <buildbot user in passwords.py> <password in passwords.py>

</pre></code>



make it autostart:

<code><pre>

rc-update add buildslave default

</pre></code>

adjust config

<code><pre>

nano /etc/conf.d/buildslave

</pre></code>







warning! you should use an ssh-tunnel to connect to the master as the password is sent in cleartext!



=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

<code><pre>

emerge layman mercurial app-arch/p7zip-9.13 dev-util/cmake app-arch/zip wine crossdev app-portage/portage-utils

</pre></code>



for java ai's / interface install a jdk

<code><pre>

emerge -va oracle-jdk-bin

</pre></code>



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

<code><pre>

</pre></code>



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

<code><pre>

<code><pre>USE="openmp cxx -fortran -multilib static-libs" crossdev --env 'EXTRA_ECONF="--disable-shared"' -t i686-w64-mingw32

==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:

shared object; recompile with -fPIC

read symbols: Bad value

enable / use it

<code><pre>

</pre></code>



re-install required libs with changed use flags:

<code><pre>

==tune==



use ld.gold for linking:

<code><pre>

binutils-config --linker ld.gold

</pre></code>



=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"

<code><pre>

binutils-config --libc 2.11.3 --linker ld.bfd

force old version of glibc for more compatibility of the generated executable:

<code><pre>

mkdir -p /usr/i686-pc-linux-gnu/etc/portage/package.mask

echo '>sys-libs/glibc-2.17' > /usr/i686-pc-linux-gnu/etc/portage/package.mask/glibc

i686-pc-linux-gnu-emerge -va dev-util/pkgconfig x11-misc/util-macros

build all libs: (we use --nodeps as else it would pull in A LOT of dependencies which aren't required. because of --nodeps, the order of parameters matters!)
