Unknown CMake command "generate_from_xml", Version 2

Unknown CMake command "generate_from_xml", Version 2

• I am trying to generate a dev version of freecad and I have been following the steps in:
  http://www.freecadweb.org/wiki/CompileOnUnix
  using "Out-of-source Build".

• I have downloaded the source thus:
  git clone https://github.com/FreeCAD/FreeCAD.git freecad-source

• I have changed the name of the directory to FREECAD-SOURCE in my home directory.

• After I enter the cmake command, I get the following error:
  
  CMake Error at Base/CMakeLists.txt:81 (generate_from_xml):
  Unknown CMake command "generate_from_xml".

• There is a warning about the cmake version number, but this is resolvable.

• This error has come up in previously:
  https://forum.freecadweb.org/viewtopic.php?t=1221

• Attached picture shows the steps I have gone through.
  (Note big_grep.sh and readme are my files.)

• The file:
  /home/peter/FREECAD-SOURCE/cMake/FreeCadMacros.cmake
  contains the definition of the macro, generate_from_xml.

• What should I do to proceed?

• Running on:
  Ubuntu 18.04
  cmake version: 3.10.2

What should I do to proceed?

cmake ../src

../src ist wrong directory. Choose ../ instead.

Thanks for the answer.

Sorry it has been some time from your response but I then tried to compile freecad but I am having compilation problems. I have spent 2 weeks trying to resolve them but I am now stuck.

Using the command: cmake --build /home/peter/FREECAD-SOURCE/freecad-build

I have removed some lines from the error messages, leaving the important ones.

FIRST ERROR:

Compiling for the first time I get:

/home/peter/FREECAD-SOURCE/src/3rdParty/salomesmesh/inc/SMDS_UnstructuredGrid.hxx: In member function ‘vtkCellLinks* SMDS_UnstructuredGrid::GetLinks()’:
/home/peter/FREECAD-SOURCE/src/3rdParty/salomesmesh/inc/SMDS_UnstructuredGrid.hxx:98:12: error: invalid conversion from ‘vtkAbstractCellLinks*’ to ‘vtkCellLinks*’ [-fpermissive]
return Links;

SECOND AND THIRD ERRORS:

After a bit of a hack with the code, casting vtkAbstractCellLinks* to vtkCellLinks* at 98 the compilation goes a bit further till:

/home/peter/FREECAD-SOURCE/src/3rdParty/salomesmesh/src/SMDS/SMDS_MeshNode.cpp:194:85: error: ‘class vtkAbstractCellLinks’ has no member named ‘GetLink’
vtkCellLinks::Link l = SMDS_Mesh::_meshList[myMeshId]->getGrid()->GetCellLinks()->GetLink(myVtkID);
this error is repeated 3 more times

/home/peter/FREECAD-SOURCE/src/3rdParty/salomesmesh/src/SMDS/SMDS_MeshNode.cpp:353:43: error: invalid conversion from ‘vtkAbstractCellLinks*’ to ‘vtkCellLinks*’ [-fpermissive]
vtkCellLinks *Links = grid->GetCellLinks();

I didn't realise that the version I downloaded was 19.
If there are easy solutions to the above problems then I would be happy to try them.
Otherwise there is no need for a response; I just want to make you aware of these problems, which may be of my making.

Thanks.

Which version of vtk do you have installed? For my Linux box vtk7 works without problems.

If you got the source code from git, of course you are getting the 0.19 version, as it's the development version.

These problems seem to be due to something missing in your system. As wmayer asks, are you sure you have all dependencies?

Compiling FreeCAD in Ubuntu 18.04 is generally not a problem. It's as easy as this.

Code: Select all

cd freecad-build
cmake -DBUILD_QT5=ON -DPYTHON_EXECUTABLE=/usr/bin/python3 ../freecad-source
make -j3

Check CompileOnUnix again.

Thanks for the answers - I will go away and check the dependencies, etc.

Thanks - it only goes to show that if you read the installation guide it all works!!
