PLEASE SEE LAST POST FOR LATEST INSTRUCTIONS !
Hi,
finally I could add this package, which I'm using in my UppCad.
It was a long run because the library source tree is totally Upp-unfriendly AND because it's so big that I couldn't drop into bazaar.
BEWARE, NEEDS AN UPDATED IDE TO BUILD !!! (nighty build from 18/01/2011)
So, here instructions :
1 - RTFR (Read The Fine Readme) !!!
2 - If you're in a hurry, please read point 1.
3 - If you're *really* in hurry, keep in mind that the Bazaar package DON'T have the library sources inside (around 30 MB were just too big...), just the .upp files and some other neede ones, so, you MUST fetch the library source tree by yourself.
So, as contained in the infamous README file, as an option :
From inside OCE folder......
If using GIT (preferred method):
git clone git://github.com/tpaviot/oce.git
If not using git, fetch files from here :
https://github.com/tpaviot/oce/zipball/master
Unpack them inside OCE folder AND BE SURE that resulting folder name is 'oce'. You'll end with OCE folder containing following:
ApplicationFramework
Draw
FoundationClasses
InterfaceGraphic_WNT.hxx
ModelingAlgorithms
ModelingData
oce <<-- THIS IS OCE source tree
OCE.h
README-REALLY.txt
Visualization
From now, you can open OCETest package and run it... if all is ok, you'll see a small demo with a 3d bottle on it.
BE PATIENT, OpenCascade is totally Blitz-unfriendly, and it's
around 30 MB of source code. On Linux it takes around 20-25 minutes to build on my machine, on WINE it takes more than one our, don't know on a real machine.
You can zoom (mouse wheel) pan (middle mouse button) and rotate (ctrl+shift + mouse middle drag).
Tested on windows an Ubuntu Linux 11.10; if you've some BSD handy, please test it and/or apply needed patches.
Please report here any bugs you find !
LAST NOTE : GIT is preferred because the OCE project is very active on these days and we're fixing tons of issues on it, so with git you can stay updated easly.
Ciao
Max

Hi,
I just updated the bazaar OCE package to latest OCE build, and so is the demo app.
Now there's just a *BIG* single library named OCE.
As before,you need to fetch the OCE sources with git from OCE website; see the readme file.
As a note, the OCE package still has a couple of bugs that prevents building on last ubuntu GCC; I pushed the needed patches in a private branch named miciomax/fix-ubuntu-build, so upon fetching the git code, you need to switch to that private branch to build it.
Resumed instructions :
1: cd into OCE bazaar folder
2: git clone git://github.com/tpaviot/oce.git oce
3: cd into 'oce' folder
4: git checkout miciomax/fix-ubuntu-build
From now you can try to build demo code.
By now, tested JUST on Linux; you may miss some dependencies, in my case it was TCL devel libraries and limxmu, but your mileage may vary... jut look at error codes, if any, and google for dependencies.
I'll test it on windows (and make needed changes...) on next days.
Ciao
Max
p.s.: the build takes LOOONG... if you don't have a fast pc with very fast HDD. On my quad core i7 with 512 GB ssd it takes some 3-5 minutes; on former machine it could take 2 ours....
p.p.s: I warmly suggest to build with USEMALLOC flag... maybe the OCC allocators are fixed now, but they were quite broken one year ago....

Thanks for the speedy reply, Max!
I am certainly not in a hurry Still, I tried your suggestions. Fix number 1 works no problem, fix 2 induces a few other errors here and there. I will not bore you with the details since I guess it would be more of a nuisance than a help - after all, the important thing is in the package itself.
What might be helpful is the following: Since fix 1 solves the Visual Studio 2012 error, I have gone ahead and compiled the project again from scratch using that toolchain. Two points arise:
- First, the VC compiler keeps saying
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Vc\Include\crtdefs.h(446) : warning C4091: 'typedef ' :
ignored on left of '__w64 unsigned long' when no variable is declared
after compiling every file
- Second, the library is linked correctly, yet the OCETest executable fails because of the following:
Linking...
Creating library C:\upp\out\bazaar\MSVC11.Gui.Usemalloc\OCETest.lib and object C:\upp\out\bazaar\MSVC11.Gui.Usemalloc\OCETest.exp
OCE.lib(Graphic3d_WNTGraphicDevice.obj) : error LNK2019: unresolved external symbol "private: void __thiscall Graphic3d_WNTGraphicDevice::
SetGraphicDriver(char const * const)" (?SetGraphicDriver@Graphic3d_WNTGraphicDevice@@AAEXQBD@Z) referenced in function "public: __this
call Graphic3d_WNTGraphicDevice::Graphic3d_WNTGraphicDevice(char const * const)" (??0Graphic3d_WNTGraphicDevice@@QAE@QBD@Z)
OCE.lib(OpenGl_Window.obj) : error LNK2019: unresolved external symbol __imp__InterfaceGraphic_RealizePalette referenced in function "publ
ic: __thiscall OpenGl_Window::OpenGl_Window(class Handle_OpenGl_Display const &,struct CALL_DEF_WINDOW const &,void *,class Handle_Ope
nGl_Context const &)" (??0OpenGl_Window@@QAE@ABVHandle_OpenGl_Display@@ABUCALL_DEF_WINDOW@@PAXABVHandle_OpenGl_Context@@@Z)
C:\upp\out\bazaar\MSVC11.Gui.Usemalloc\OCETest.exe : fatal error LNK1120: 2 unresolved externals
Still, it's very very close... Thanks Max for the great job!

Hi,
for the second error, I already sent a patch to OCE which is being integrated.
If you want to test it, there's a private branch named
review/fix-static-build
which contains the fixes.
Sorry for the inconveniences, but OCE is in the way incorporating 6.5.4 update, so it needs some days to stabilize.
BTW, with the patch I got it compiling and running or both on windows (visualc 9) and Linux (ubuntu, GCC 4.7.2).
Feel free to signal more problems.... I'm a bit busy on these days, but I'm thinking to continue development of my UppCad application, so I guess I'll be faster with updates on next days.
Ciao

Hi again Max,
No need to apologise for inconveniences! On the contrary, it's the whole community that is grateful to you and to the rest of the people who make it possible for us all to reap the rewards of your hard work. Personally, I am just happy to contribute in any humble way I can if with that I can make your life a little easier, that's why I thought I would present my own experience in case it might help out.
Let me make that extensive to all the really talented folks working on U++. Guys, you all rock, seriously.
Back to the issue: I will certainly keep testing the new version, not only compiling it but also working with the final product, so if something comes up, I'll be sure to let you know.
Thanks again, cheers,
Kel

I've uploaded a demo (NON open sourced, just the executable and a test file) of the ongoing uppcad project, based on OCE libraries.
It's still in early stage, but many stuffs are already working.
If you want to test it, just grab these files:
http://www.timberstruct.it/UppCad.exe
http://www.timberstruct.it/prova.ucd
(.ucd file needs to be saved on disk, so if your browser opens it, just choose 'save as' option instead)
To test, just run UppCad.exe and open the Prova.ucd file.
Usage is simple, only 'weird' thing is the view rotate command, which is done with
CTRL+SHIFT+middle mouse button drag
To see view in shaded, random colors, just select GOURAUD view mode. HIDDEN line mode is quite slow when rotating the view, as it must regenerate all hidden lines on each step.
Ciao
Max
