Problem building java binding on Arch Linxu

[mitkof6]

I am getting the following error at the end of the compilation when the binding are compiled:

org/opensim/modeling/StdMapStringTimeSeriesTableVec3.java:57: error: incompatible types: SWIGTYPE_p_std__mapT_std__string_std__shared_ptrT_OpenSim__TimeSeriesTable_T_SimTK__Vec3_t_t_std__lessT_std__string_t_t__iterator cannot be converted to Iterator
    Iterator itr = find((String) key);

Do you have any directions how to fix this?

Which SWIG version are you using?

[mitkof6]

Hi. I used SWIG 4.0.1.

[chrisdembia]

opensim-core does not yet support SWIG 4 :(

[mitkof6]

Thanks. I did not expect to have backward compatibility issues. For python it seems to work with newer versions, but not with Java. Maybe this error can be fixed. Are you aware of this issue?

[chrisdembia]

We are aware of this issue, and we do not have a fix yet. I think it's a bug with SWIG. If you find a fix, that would be great :)

#2707
#2524

A quick fix is to comment:

%template(StdMapStringTimeSeriesTableVec3)
        std::map<std::string,
                 std::shared_ptr<OpenSim::TimeSeriesTable_<SimTK::Vec3>>>;

in Bindings/common.i. Do you think that this object will be used?

[chrisdembia]

Unfortunately, yes, it's used here:

opensim-core/Bindings/Java/Matlab/Utilities/osimC3D.m

Lines 64 to 71 in c00135a

	import org.opensim.modeling.*
	% Use a c3dAdapter to read the c3d file
	c3dAdapter = C3DFileAdapter();
	c3dAdapter.setLocationForForceExpression(ForceLocation);
	tables = c3dAdapter.read(path2c3d);
	% Set the marker and force data into OpenSim tables
	self.markers = c3dAdapter.getMarkersTable(tables);
	self.forces = c3dAdapter.getForcesTable(tables);
