It works with Windows10. But Jenkins fails on Mac with message

I have now build it in a VM with Ubuntu 16.0 LTS. There too I get an
error. Here the message is

What is needed for these systems? Does it make a difference whether it
is a debug build or not? My current Windows setting is a non-debug
build, in the Linux VM it is a debug-build.
In include/svx/svdoashp.hxx, the SdrObjCustomShape member functions
GetInteractionHandles and DragMoveCustomShapeHdl are marked as
SVX_DLLPRIVATE (i.e., SAL_DLLPRIVATE). On Windows, that happens to have
no effect, but on other platforms it prevents those symbols from being
exported from the svxcore library, so you can't actually access those
functions from test code.
The technically preferred solution would be if you can somehow avoid
calling those functions directly from the test code. Less appealing
hacks to get it working are either to not mark those functions as
SVX_DLLPRIVATE in include/svx/svdoashp.hxx, or to make
svx/CppunitTest_svx_unit.mk use gb_CppunitTest_use_library_objects to
directly include (copies of) the svxcore objects, instead of using
gb_CppunitTest_use_libraries to link against the svxcore library.
