Errror: importIFC test failed

[teobo]

Hello,
when test importing one of the ifc-houses I get the error message:

Code: Select all

import importIFC
importIFC.DEBUG = True

>>> importIFC.open(path+"window-house--Allplan2012.ifc")

Installing IfcOpenShell is a bit more than copying these files, there are python bindings too.
to make sure IfcOpenShell is properly installed, try this from a python console:

Code: Select all

import IfcImport

If nothing happens, then ifcopenshell is correctly installed. But apparently it is not...
The internal parser is indeed very buggy and anyway very limited, it will be removed in next versions...

Installing IfcOpenShell is a bit more than copying these files, there are python bindings too.

What would have to be done for IfcOpenShell to be seamlessly integrated in FreeCAD? IMO this will be an important step for Arch WB.

Basically people willing to compile and pack ifcopenshell for windows...

So I give it a new try and start from scratch:

Code: Select all

 http://ifcopenshell.org/code.html
 svn co https://svn.code.sf.net/p/ifcopenshell/svn/trunk ifcopenshell
 cd ifcopenshell/cmake
  cat ~/ifcopenshell/README 
  mkdir build
  cd build
  kubuntu@kubuntu:~/ifcopenshell/cmake/build$ cmake ../
-- Boost version: 1.54.0
-- Found the following Boost libraries:
--   program_options
-- Boost include files found in /usr/include
-- Boost libraries found in /usr/lib/x86_64-linux-gnu
-- Looking for opencascade include files in: /usr/include/opencascade <-
-- Use OCC_INCLUDE_DIR to specify another directory
CMake Error at CMakeLists.txt:22 (MESSAGE):

See also "/home/kubuntu/ifcopenshell/cmake/build/CMakeFiles/CMakeOutput.log".
kubuntu@kubuntu:~/ifcopenshell/cmake/build$ find /usr/ -name "*opencascad*"

So it appears that the make script does not find opencascade, maybe some of you know where are the requested file respectively which ubuntu packages are providing them?

Aren't there build instructions on the ifcopenshell website?

Otherwise:
dpkg -l | grep -i opencascad gives you what opencascade-related packages are installed on your system.
dpkg -L packagename gives you the file installed by a given package. Try with any of the -dev packages, they usually contain the /usr/include stuff, and figure out where they do. In my case it's in /usr/include/oce
use cmake-gui in the build dir to correct the OCC_INCLUDE_DIR variable
