Re: Changes to graphic context handling
Fred,
I tried the new svn 24903 with your changes. It looks like printing
works now, when using the art backend. Cairo does not generate good
EPS, but at least it tries.
On the related subject of Cairo, I just submitted 3 bug reports,
including the printing problem. I submitted the TestApp that I used
for debugging NSBitmapImageRep that you might find useful.
Cheers,
Mark Tracy

In my program, since the view is not associated with a window, nil is

I changed it to read:

NSGraphicsContext *ctxt =

Hi Mark,
thank you very much for this bug report. It shows that somebody is
using
the print functionality in GNUstep. What you are doing is quite
legitimate and GNUstep has to support it.
I have tried to correct the problem you found in a slightly different
way. Could you please have a go with current SVN source and report
back,
if it still fails? There will be a couple of further changes to the
graphics context handling in the next weeks. I try to do this big
change
rather smoothly, but you already discovered the first error here. So
please test this from time to time for new errors.
Cheers,
Fred

I was wondering, if anyone an answer my question, there is any default file manager with Etoile? i.e. GWorkspace? and why not work in a cooperative mode with other GNUStep developers?

You can see how Gnome or KDE started and now is the default GUI and develop environment in *NIX So guys! some times is better not be selfish (sorry if I'm been rude), but having open mind and talk and integrate others GNUstep applications will help to bring GNUStep on to the next step. I've been looking at GNUStep for the last 5 or 6 Yrs, and until now things looking a bit better, Why?, because guys like you guys are doing things right, so keep my comments on mind and keep doing well, and do not forget integration with others application and talk, talk, and talk about GNUStep / Etoile last thoughts that could benefit the project. *Networking *Admin tools for *NIX *Deveoper tools (Gorm and Project centre) *GORM's palletes (functional, i.e DB, 3d Funtions, graphics funtions, etc) *OpenGL integration (beryl) (yeah!

Thank you for these bug reports and especially for the great test
application. I ran it on my Linux machine already and was able to fix
the GSReadRect:. Next I will try it on my Apple laptop to see the
expected results there.

RE: Problem building gnustep-base tools with MinGW
Hi XSLT is #***ed on Windows. It compiles as a static library, and its imports end up overriding the imports in gnustep-base.dll when you do a -lxslt, such that all of the libxml2 and gnustep-base exported symbols get obliterated (all the __objc_ and NS* functions). I don't know what the solution is, but I usually leave xslt out. If you have a copy of Visual Studio 6 lying around, the depends tool in it will give you an idea of what I mean (run it against gnustep-base.dll). We should contact the xslt people and let them know about this, but likely they don't have the time to fix it as its a Windows compile issue. I'm not sure, but I think the gnuwin32 binaries with libxslt precompiled using VC++ may work. These are hidden on the sf download page of this project. Regards Chris lcomdlg32 -lmpr -lnetapi32 -lm -I. The only difference that I can see if that you have -lxslt ... could it be anything to do with the problem ? xslt is installed since a very long time... But it seems you're right !!
