I already fixed my building/linking problem.
No need to worry about it.

> ===Week 5 report===
> ==This week==
> *Improved stuff on the test-script (theeth fast-reviewed it and gave some
> nice clues)
> *Fixed bugs that were found last week by the test-script
> *Added documentation on wiki
> http://wiki.blender.org/index.php/User:Jaguarandi/SummerOfCode2009
> *Started selection on test scenes and identified a few test cases (
> http://wiki.blender.org/index.php/User:Jaguarandi/SummerOfCode2009/TestScenes)
> <= althought I still don't have the scenes to test those.
> Anyone is welcome to contribute for scenes that match the described setups.
> ==Next Week==
> *add counters/statistics on render code and look on metadata/stamp export
> *get other machine ready to run tests
> *gather more scenes
> ==Questions==
> =1=
> I am getting lost on the render pipeline (or at least losing time on
> reading it), can anyone give me clues on:
> *Where should I export counters from raytree build and from each raytrace
> call?
> *Where does the shading code starts (and in what way can I better isolate
> raytrace and raytree creation time from the other processing time)?
> *Where can I merge counters from each thread?
> =2=
> I have spend some time trying to setup the test system on an ssh account
> (that runs on Xeon3.2, a quad core.. since testing on my eeepc or my desktop
> would just be too slow).
> Altought I have quite a few limited space on that account, so I need to
> compile on other machine and move to there. I am having some troubles with
> that.. for missing libs. This would be fixed by having all libs static..
> But do all libs have WITH_BF_STATICblabla options?
> Including the libgettext ?
> How can I create a blender with the least or even zero dependencies?
> =3=
> About the bug I reported on SUN lights..
> there are 2 options:
>  *make the new code behave wrong like old render code
>  *just have it fixed
> Anyway this isn't a priority atm.. so it can be address later.
> =4=
> I dont exactly have any show-off until now...
> Appart from instance-support (there was already a bn post on that)
> Speedup is still not done and very inconclusive atm since I haven't tested
> any real-case.
> I can hand-craft a scene to show speedup (like 13x times faster :p).. but
> that doens't counts.
> ==Schedule==
> I am on schedule (or maybe 1 week ahead).. and by the midterm I will have
> all issues sorted out and be fully ready to start the optimization part, as
> the first part was:
>  *raytrace recode (instance deliverable is done)
>  *test-script and test-environ (close to be ready)
> I must get more ahead of schedule, for the break in end of july.
> I already have dates for that 20july to 31july.
> *my last exam is day 29 june. At last!
