Bricscad for Linux alpha

Yeah I have 64bit madriva2010.

It not will be 64bit version off bricscad?

Jeah it is very alpha stage of projekt ( without any command butons )

OK, this is a real proof of committment, and as such already an upbeat start into 2010.

However, IMHO, the released material nourishes a number of questions and doubts rather than the expectation to see a mature application in the near future.
Apparently (looking at the included/required libs), Bricsys is following an all-at-once development strategy: all bells and whistles already attached, while the application isn't even capable of opening the main window. I'm not a programmer and can not judge this, but a more incremental approach would have seemed preferable to me.
My preferred appetizer would be a very basic dwg-viewer that takes a filename as an argument and displays it in a plain X11 (perhaps OpenGL) window, using only the mouse buttons to zoom around. This could act as a testbed/showcase for the base technologies and be at the same time useful enough to attract much attention (or even become a standard part of the major Linux distros, if given away for free). If the lacking functionality would be added in iterations (first the cli, than lisp, than other api ...finally the gui), the program could be stable and performant before going into beta, with download-sizes starting small and gradually increasing.
The way it seems to be heading, I fear I will have to download gigabytes of alphas and betas, just to discover that each version runs perhaps 3 seconds longer than the previous before crashing... (hope they'll prove me wrong).

Some other first impressions:
- will it really be possible to build a professional CAD-system on pango/cairo (sure it'll look nice, but what about display performance)?
- on my debian stable, besides the usual stuff, libxerces/icu weighing about 20mb had to be installed
- will the advanced lisp-interpreter that found its way into bricscad v9 be part of it? At the moment you can't do (+ 1 2)
- is the included (superheavy) libwxgui a special build, or couldn't debian's libwx(-dbg, 2.6.3.2.2-3) be used as well (to shrink the download a bit)?

(oh, don't get me wrong, I'm really delighted something happened at last)

to Knut Hohenberg,

well, I'm not a bit fan ow wx either, but it's one of the few well tested multi-platform toolkits. About the "all-at-once" development, I think

it's quite common using a cross-platform gui toolkit, they first developed on windows, then ported to Linux.

What makes me wonder is the state of the alpha version... having a cross-platform lib AND a stable windows release, I'd have expected a

more complete alpha version.... I just hope that they've just a couple of blocking bugs before a semi-stable (usable) version appears.

Again, I don't know very well wx, but I'm using another cross-platform gui/library (Ultimate++) which makes the porting as easy as

recompiling on different os, almost no changes needed on source code.... I start thinking that wxwidgets require some more (hard) work

for porting. Or (and I hope to be wrong....) the windows version uses too many platform-dependent stuffs.... In that case I'm afraid we'll

have to wait a couple of years more to see an usable Linux version.

Hello, this is the error when launching bricscad.sh:

error while loading shared libraries: libxerces-c.so.28: cannot open shared object file: No such file or directory

After installing " libxerces-c.so.28" the error is:

(bricscad:2803): Gdk-CRITICAL **: gdk_drawable_get_depth: assertion `GDK_IS_DRAWABLE (drawable)' failed
Segmentation fault

My system is Ubuntu 9.10 i386

Thank's..

Sweet! 12 years of searching and waiting finally looking like the real deal...

zoom... (^_^)

waiting with baited breath.

well it opens... no menu, no icons, just the black screen and the command bar... then i get

(bricscad:23087): Gdk-CRITICAL **: gdk_drawable_get_depth: assertion `GDK_IS_DRAWABLE (drawable)' failed
Segmentation fault

and closes...

yey....

Hi,

As Erick and Tijs mentioned this is still short of being an Alpha we can not yet judge the new Linux version as it is being made available just to satisfy our unrelenting thrist of knowing that there is something going on.  Having been a Bricscad user for several years now I am always pleasently surprised with the quality of the support and programming and the effort they put to please our needs.  I am sure we will soon see the Linux version running smooth and up to our expectations.

Thanks to the Bricsys team for this great effort to provide us with a usable program in a Linux Platform that will help us consider the possibility of setting up design and drafting teams running solely on Linux.  I do remember that before I decided for Bricscad because of their excelent Windows program I first approached the company because it offered the intend of eventually providing a Linux version, the wait has been longer than originally anticipated but I am sure the Bricsys team will make it worthwhile.  Thanks again, you just made our expectations of 2010 better.

Regards,

José

BTW :

I'm running the Ubuntu 9.10 on a 32bits architecture.

For Isaac Salgado

thank you in advise Now I got a little bit GUI before crash

For all

[code]

BricsCAD> sh bricscad.sh

[Debug] 09:28:39: ../../../src/gtk/glcanvas.cpp(318): assert "m_vi" failed in Create(): required visual couldn't be found

[Debug] 09:29:28: ../../../src/gtk/window.cpp(3055): assert "(m_widget != __null)" failed in Show(): invalid window

Segmentation fault

[/code]

I got this in opensuse 11.2 x86 (i run it in VirtualBox)

I wait the 64 bit release or at least the beta release (I hope that will become real). If you make it that will be great (there are years that I wait - 2004-2005 - i'm not shure may be before). If you need I can do the beta tester... (I'm already a user of BricsCAD linux version 6.0.0020. - beta also that one - it have some bugs).

Thank you, you're great!

Just another (I guess easy to fix) stuff : giving a command by command line makes the keyboard focus to go somewhere else, so

I must click again on cmdline to keep entering input on it.

It crashed once, if you need some logs just ask !

Ciao

Amazing!!

last update now work on ubuntu 9.10 64bit either 32bit.

I've the same observations as Massimo Del Fedele about the new release but I want to add one from my tests:

I found a tiny problem on 32bit platform using desktop effects (compiz fusion): display refresh doesn't work fine.
all goes well if I disable desktop effects.

Very good job!

These alpha builds are disclosed to allow those who are curious, to personally verify that we _really_ are working on a native Linux Bricscad version: we very much appreciated all your encouraging, hopeful and longing comments on this forum, so in return we want to give you tangible proofs of our commitment and progress, not just words.

We are aware that there are a ton of issues to be solved, in this stage it is too early to start reporting bugs, still: your readiness to help us make good progress is heartwarming. Thanks!
