Hi, Carlos!
We use Fedora's crosscompile packages on Windows, so the boost comes
from the Fedora repositories.
See this line:
fedora-mingw-install mingw${ARCH}-boost
Other line that you referenced is not executed, because it belongs to
outdated/disabled block of code (which in fact could be safely
removed).
Back to your question: currently we use packages from Fedora 18. If
you want to get boost 0.53.0, then you need to switch to Fedora 19. In
fact, I believe it is safe to do that as permanent change to the
script. ^__^
Just find this line:
URLS=`yumdownloader --urls --resolve -c $WORKSPACE/mingw-rpms/yum.conf
--releasever=18 --installroot="$WORKSPACE/mingw-rpms" $1`
and replace "--releasever=18" to "--releasever=19"
Regards,
K.
