FreeCAD 10 on gentoo

[chrisb123]

Hi

There is an ebuild for FreeCAD on gentoo but it is for V9 rev 2646
Will there be an update to a newer version?

[jriegel]

This is done by a third party, so we dont know....

[psi13art]

These are the official ebuilds

• dev-util/boost-build
  dev-libs/boost
  app-admin/eselect-boost
  dev-python/PyQt4
  dev-libs/xerces-c
  media-libs/coin

I've used Overlay "science" (with the help of layman)

sci-libs/opencascade 6.3-r2

cmake didn't configure freecad becaue it couldn't detect coin3d, OOC. As a solution I bluntly changed the paths in the /freecad/CMakeCache.txt file.

• COIN3D_DOC_PATH:PATH=/usr/share/doc/coin-3.1.3-r1/
  COIN3D_INCLUDE_DIR:PATH=/usr/include/coin
  OCC_INCLUDE_DIR:PATH=/opt/opencascade-6.3/ros/inc
  OCC_LIBRARY:FILEPATH=/opt/opencascade-6.3/ros/Linux/lib

Code: Select all

~/source/freecad $ cmake .

What's ODE? At the moment, I couldn't repack (compile) freecad because of this following error:

I'll be looking for a solution at this forum now.

[chrisb123]

I had to make a change with something to do with opencascade
There is a freecad10 ebuild floating around somewhere on bugzilla, it works for me

[psi13art]

Thank you very much!
http://bugs.gentoo.org/show_bug.cgi?id=312063 - is that it?

Everything installed properly and works fine, which is great.
And how did you overcome Pivy?

Code: Select all

Pivy and PyQt4 python modules must be installed on your system to use the 2D Drafting module.<type 'exceptions.AttributeError'>

[chrisb123]

I wouldnt know as I dont use 2d drafting
If anything I might have used the unstable pivy and pyqt4 bindings, but i dont use 2d drafting

[yorik]

I'm pretty sure some people already managed to run pivy on gentoo in the past...
Have a search on this forum, you might find more info

What's ODE?

Open Dynamic Engine is a library which will be used when starting with the Assembly module. But for the moment you can silently ignore it.

Code: Select all

At the moment, I couldn't repack (compile) freecad because of this following error:

Code: Select all

error: NCollection_DataMap.hxx: No such file or directory

NCollection_DataMap.hxx is an OCC header file.

And how did you overcome Pivy?

With the latest source tarball we also provider the generated source files for pivy. Actually it should build the pivy python module without further tweaks.

[psi13art]

NCollection_DataMap.hxx is an OCC header file.

I'm Sorry

I rechecked the path to the libraries

Code: Select all

//Path to a file.
OCC_INCLUDE_DIR:PATH=/opt/opencascade-6.3/ros/lin/inc

//Path to a library.
OCC_LIBRARY:FILEPATH=/opt/opencascade-6.3/ros/lin/lib

And there is a new error

I'm using very unstable ebuild 9999999 http://bugs.gentoo.org/show_bug.cgi?id=291161 and it worked (all! include draft! FreeCAD 0.11)!

[wmayer]

TKernel is one of the OCC libs. Make sure that you add the right path to your linker.
