some issues with coin3d updated to boost 1.70:

THe problem with coin was solved by using:

Code: Select all

-D Boost_NO_BOOST_CMAKE:BOOL=ON \

Now I am stuck with FreeCAD. Linux has a conda-specific problem with vtk-configuration. On windows a problem with boost-libraries is reported:
https://ci.appveyor.com/project/conda-f ... 8370#L1388

Code: Select all

bin\FreeCADBase.dll : fatal error LNK1120: 3 unresolved externals

edit: this build uses source for FreeCAD 0.18.2. So it's possible this is already solved in master.

Is it possible we are not linking against boost/regex which is needed in Interpreter.cpp?

The previous reported problem for windows was solved by using:
-D Boost_NO_BOOST_CMAKE:BOOL=ON for windows too. But now there is another problem:

Code: Select all

%PREFIX%\Library\include\boost/system/detail/system_category_win32.hpp(52): error C2039: '_snprintf': is not a member of 'std'

similar issue here:

This are the relevant lines for the reported boost-error: https://github.com/boostorg/system/blob ... hpp#L29L56

After patching vtk-cmake for linux the build works but FreeCAD fails at runtime. Maybe someone knows what the error message means:

Code: Select all

One possible reason is that somewhere a Python C function is used without locking the GIL. However, there can be many other reasons for an "abort".

I think the important information here is:

linux problem found: I previously added a patch to smesh which result in the reported issue. removing the patch and using sed to remove some wrong paths in the vtk-library resulted in a working smesh-freecad combination. There will be an updated smesh available soon (hopefully) [1]

Now only the windows issue has to be resolved. Somewhere in the headers of the dependencies or in freecad-source itself there must be a definition of _snprintf this somehow conflicts with std::snprintf.
