#2040 assigned task

buildbot switch to docker

Reported by: Antoine Martin Owned by: Antoine Martin
Priority: major Milestone: 2.5
Component: packaging Version: 2.4.x
Keywords: Cc:


Based on #2028, we can have a base image with the main build dependencies for each distro supported.
ie for centos7, here's a list of packages, not just xpra but also the build dependencies for some of the other packages we have to provide:

xorg-x11-server-devel sudo epel-release krb5-devel python-devel rpm-build pkgconfig which
#gstreamer plugin:
gstreamer1-devel gstreamer1-plugins-base-devel
gtk2-devel libGLU-devel libXmu-devel libXt-devel pangox-compat-devel
ncurses-devel libXinerama-devel
pango-devel pygtk2-devel
numpy python-distribute boost-devel
openssl-devel python-setuptools
tkinter tk-devel libjpeg-devel lcms2-devel PyQt4

Not sure if all the dependencies should be in the base image, or only added when we build the package that requires them. (so many packages..)
Then we have to install the packages we build for the next step:

  • pangox-compat
  • gtkglext
  • pygtkglext


  • lz4
  • python-lz4

So some form of scripting is likely to be needed to manage those dependencies.

Other distros may not need to build some packages (ie: python-pillow is in the Fedora repository).

This can then be used to build the master image for building xpra.

Example of something difficult to handle: http://winswitch.org/trac/ticket/307#comment:6: we need to build lz4 on centos, except on centos 7.4 and later..

Another problem: mock 1.4.2-1.el7 fails to build el6 packages and systemd-nspawn cannot change user with EL6 chroot.
I was getting getent initgroups failed with error code 1., worked around that by using nspawn as root and running su -l buildbot from there..

And another: we need a recent version of nasm to build x264, r21315 adds a spec file so we can package the latest release. But on centos6, it does not build:

configure.ac:3: error: Autoconf version 2.69 or higher is required

  • pycuda 2014.1 is the last version that can be built against the version of numpy found in the centos6 repos, and the specfile for 2014.1 is found in our 0.15.x release!
  • cuda 7.5 is the last release suported by pycuda 2014 / centos6

And installing older versions of CUDA on fedora is not easy because we're missing attachment/ticket/2040/InstallUtils.pm... so run it like so:

sh cuda_5.5.22_linux_64.run -verbose -override -extract $INSTALLER_DIR
wget https://xpra.org/trac/raw-attachment/ticket/2040/InstallUtils.pm
PERL5LIB=. ./cuda-linux64-rel-5.5.22-16488124.run --prefix=$INSTALL_DIR -noprompt

Another issue similar to comment:2 is when the distro ships a broken package (ie: either out of date version or buggy packaging): in this case we want to ship a working package, but stop doing so if and when the distro fixes things.

Example: python-uinput broken in Fedora 24 to Fedora 29! (~3 years without a fix!)

Out of the 40+ builds, one slipped through with the wrong ffmpeg dependency: Error: Package: ffmpeg-xpra-4.1-1.el7_6.x86_64 (Xpra)..

new constraint: some versions may require a package (ie: versions before 2.5 require websockify and python-websocket-client - see #2121), but not after. Yet we need to keep the RPM specfile updated and update the repository from that branch - until the distribution ships it / updates that version.
