      Hi, Fabio!<br>
      <br>
      I managed to compile and run compositor-spice with the latest
      weston master branch. See last <a moz-do-not-send="true"
href="https://github.com/ein-shved/compositor-spice/commit/585cbd281fd4c4685df83d22d60ec5670479b474">commit</a>.<br>
      <br>
      Here, how I did it:<br>
      <br>
      export PREFIX=$HOME/usr #setup prefix variable. You can choose
      another or use default one<br>
      <br>
      sh autogen.sh --prefix=$PREFIX --disable-weston-launch
      --enable-spice-compositor #configure with different preffix,
      spice-compositor and without weston-launch to install as normal
      user<br>
      <br>
      make -j8 && make install && ./src/weston
      --backend=spice-backend.so #compile project with 8 threads,
      install modules and run weston with spice-compositor.<br>
      <br>
      <br>
      On another terminal run<br>
      spicy --display=:0 -h localhost -p 5912 # to connect to spice
      server.<br>
      <br>
      Please try it by yourself and let me know the results!<br>
      <br>
      This is only the first step. Next we need to remove all
      unnecessary code, change backend to good weston coding style, move
      to new spice API and check it with valgrind and unit-tests. <br>
      <br>
      After that we will think about optimization. Firstly, make all of
      it like in RDP.<br>

        I don't suppose myself the master of git but in my opinion using
        git rebase is a bad practice:<br>
        <ul>
          <li>rebase can rewrite the history. It can take the part of chain and move fully in another place. While merge doesn't changes history. It simply creates new commit on top of two branches</li>
          <li>with rebase in case of conflict you have to resolve them in many commits, while with merge you need to resolve conflict once at the top</li>
          <li>sometimes you need to perform code changing while action. In rebase you have to do it in several commits, while with merge - only in one</li>
          <li>rolling back the rebase could be really painful 
</li>
          <li>I already had problems with rebase, so now I use it only when it is realy needed and when I can't use merge (never).
</li>

            </blockquote>
            I spend much time for reading spice source code to
            understand its API far in 2013. To understand it you have to
            read sources as I. I remember that in fact spice protocol is
            - to say simple - drawing API. You can draw stuff from
            spice-server on spice-client's screen. Anyway we need to
            learn new api, reading example source code as I did.<br>
            <br>
            I did simple <a moz-do-not-send="true"
              href="https://github.com/ein-shved/qxl-test">example</a>

After update to newer api I suppose will be good add also a required spice-server version check in configure based on newer api, I found this that seems will make fast see at what version was added any api:

Another important note if you don't know it, spice-server recently is under heavy changes, latest version (0.13.0) is like a "devel snapshot".
Latest stable version that I think is good to use also with this project for now is 0.12.6.</p>

                    - in configure.ac some changes seems strange,
                    including LIBS and CFLAGS that <br>
                    seems "double" <br>
                  </blockquote>
                  I think this can be removed. Usually setting
                  LIBS/CFLAGS and <br>
                  foo_save_LIBS/foo_save_CFLAGS is used for an
                  AC_CHECK_* call, which <br>
                  relies on LIBS and CFLAGS already being set. I guess
                  there may have <br>
                  been a call here which has since been removed. <br>

                  </blockquote>
                  There is no documentation on the change, no. <br>
                  <br>
                  As you can see, several functions have changed: <br>
                     - weston_output_finish_frame now takes a struct
                  timespec rather than <br>
                  an integer number of milliseconds (trivial conversion)
                  <br>
                     - the output repaint function now returns an
                  integer marking success <br>
                  or failure <br>
                     - the compositor interface has now changed to
                  weston_backend, and <br>
                  you can see examples of the changes required in commit
                  954f183e <br>
                  <br>
                  Hope this helps: just pick out the warnings and errors
                  one by one, and <br>
                  try to figure them out - searching git commits for
                  anything relevant <br>
                  always helps - until you get something that builds. <br>
