Re: [Openev-discuss] Status on OpenEV2 + S52? (+ a few bugs)

[s d. <syl...@ya...>]

Hi Joel,

>This one is mostly for Sylvain. What is the status on the s52-code right now?

Still experimental :)

>What works, what doesn't? 

Try s52glx target 

Then try s52gtk2 target

> And what are your development priorities? 

I work on s52gtk2 and s52win32 at the moment

> Which "frontend"
>is being worked the most on?

I don't have a front end (GUI)

I used to get a GUI from the python part of OpenEV

But right now work with OpenEV core (libgv.so) 



>The last couple of days, I've been trying to get the latest CVS version of the s52
>code to work with OpenEV2 (the s52gv2 target). No real success yet.

Fixed s52gv2, should be in CVS later today.

got it ..

I've seen this before, something about linking. So just try to build/run s52gtk2 (this should work right now).
