<p class="MsoPlainText">Tim, Kornilios,<o:p></o:p></p>
<p class="MsoPlainText"> Thanks for the help. The new release fixed the trace_defs.h file missing problem. I’m now able to build barrelfish and run the examples under QEMU.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Thanks,<o:p></o:p></p>

<p class="MsoPlainText">>Dear Mark,<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">>The trace definitions file should be generated very early on in the build process, since lots of parts of the system >include it.<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">>The first thing to try is start with a completely clean (i.e. empty) build directory, and run hake to create a new >Makefile. There are some limitations on dependency tracking that mean that an older, failed build (such as you might
>get by using a different version of ghc) make it hard to eliminate some bad dependencies.<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">>If that doesn't work, there may be a bug in the trace Hakefile. We're doing a release this afternoon that may fix it, >but a good way to debug things (and, indeed, work around them) is to try:<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">>$ make trace_definitions/trace_defs.h<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> - in the build directory. If this succeeds, you should then be able
<o:p></o:p></p>
<p class="MsoPlainText">>to use other make targets without problems. As an aside, Hake
<o:p></o:p></p>
<p class="MsoPlainText">>generates a single Makefile with an explicit rule for every file, so you should be able to find the commands to build >trace_defs.h.<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">>Hope this helps,<o:p></o:p></p>
