Hi and thanks for the report! What's your compiler and OS ?

Dear Maintainers,

after pulling revision 5448704355e03a97d2838e1ba30272db335f0dbb I try to build inkscape according to https://inkscape.org/develop/getting-started/ but I receive the following error:

In file included from /usr/include/c++/7/memory:80:0, from /vol/pub/inkscape/linux/git/inkscape/src/document.h:25, from /vol/pub/inkscape/linux/git/inkscape/src/object/sp-use.cpp:27: /usr/include/c++/7/bits/unique_ptr.h: In instantiation of ‘void std::default_delete<_Tp>::operator()(_Tp*) const [with _Tp = SPCurve]’: /usr/include/c++/7/bits/unique_ptr.h:263:17: required from ‘std::unique_ptr<_Tp, _Dp>::~unique_ptr() [with _Tp = SPCurve; _Dp = std::default_delete<SPCurve>]’ /vol/pub/inkscape/linux/git/inkscape/src/object/sp-use-reference.h:45:50: required from here /usr/include/c++/7/bits/unique_ptr.h:76:22: error: invalid application of ‘sizeof’ to incomplete type ‘SPCurve’ static_assert(sizeof(_Tp)>0, ^ My questions:

• are there simple means to avoid that error?
• what information about my building environment is required?

BTW: I am trying to build Inkscape because the AppImage crashes.

Thanks and best regards

Torsten
