I tried adding this in kicad.i #include <geometry/shape_line_chain.h> %include <geometry/shape_line_chain.h>
It compiles and SHAPE_LINE_CHAIN type shows up in pcbnew.py But I need VECTOR2I as well to get the actual coordinates. However adding math/vector2d.h header in a similar way leads to following linking error that I am not sure how to fix: D:/devtools/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/7.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: CMakeFiles/pcbnew_kiface.dir/objects.a(pcbnew_wrap.cxx.obj):pcbnew_wrap.cxx:(.rdata$.refptr._ZN7VECTOR2IiE10ECOORD_MINE[.refptr._ZN7VECTOR2IiE10ECOORD_MINE]+0x0): undefined reference to `VECTOR2<int>::ECOORD_MIN' D:/devtools/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/7.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: CMakeFiles/pcbnew_kiface.dir/objects.a(pcbnew_wrap.cxx.obj):pcbnew_wrap.cxx:(.rdata$.refptr._ZN7VECTOR2IiE10ECOORD_MAXE[.refptr._ZN7VECTOR2IiE10ECOORD_MAXE]+0x0): undefined reference to `VECTOR2<int>::ECOORD_MAX' Can someone who understands swig help me figure this out?
