WG: kst 2.0.0 beta3I have a colleague who's
tried kst 2.0.0 beta 3. He liked it, apart from a worrying problem which he
describes as follows: Starting
a fresh kst2 session, with a .kst file having 2 tabs, the first tabs contains 8
plots with 1 to 3 curves each and the 2nd tab has 3 plots with 3
curves each. Each curve contains from 2 to 12000 points. Just
after starting, kst2 requires about 92MB RAM. When just scrolling the mouse
pointer over kst2, this amount increases by ~5MB each time the active plot
toggles or if the tab is changed.. and the memory needs increases, increases
until kst2 crashes (by ~1.1GB) It
looks like a memory leak is trapped somewhere…. Sounds like something we
should do something about! Nicolas From: Brisset, Nicolas
Je t'ai mis sous
U:\Verlut\build.zip une archive avec tous les binaires générés. Apparemment,
ils sont faits avec des librairies statiques et en mode debug, donc immenses.
Mais je n'ai pas trop le temps de chercher comment les faire autrement. Tu
devrais t'en sortir en les mettant à la place des anciens. Tiens-moi au
courant… Nicolas P.S. : le mieux serait presque
encore que tu te fasses ce boulot direct chez toi, il suffit de charger la
version 1.2 de Qt Creator et
ensuite
de lancer la compil… Von: Je veux bien oui J Grégoire From: Brisset, Nicolas
Grégoire, j'ai oublié de te dire à midi, mais kst 2.0.0 beta 3 est
sorti et devrait commencer à être utilisable (cf mail joint du développeur
principal : " the first that is
useful"). Si ça t'intéresse pour les essais WAAS à venir, j'en ai une
version compilée pour Windows sur un coin de mon disque J Nicolas BRISSET ______________ Research & Development – Eurocopter Group ETGC – General Engineering / Flight Controls

Re: WG: kst 2.0.0 beta3Thanks, Nicholas! I'll get right on this. This was under Windows, correct?
Debug build? Good thing we called it a beta! cbn On Tuesday 13 October 2009 08:04:13 Brisset, Nicolas wrote: > I have a colleague who's tried kst 2.0.0 beta 3.

Re: WG: kst 2.0.0 beta3> Thanks, Nicholas! I'll get right on this. This was under Windows,
> correct? > Debug build? Yes, it was under Windows, compiled with Qt Creator 2009.02 (Qt version 4.5.1), with the default build options. I just unpacked the kst-2.0.0beta3 archive, opened kst.pro in Creator and clicked on "Build all". The resulting exe is 43 MB (!) so yes, I suppose it is a debug build :-) I don't know how far your son has come with preparing a Windows package, but one thing is sure: he'll have to change the build options. And one thing I haven't tried is to compile gsl under Windows so that we can have all the nice plugins based on it. It would be nice to do it...
