Hi guys,

I use Visual studio 2017. The codes are built ok with 2015. I use static lib. Does anyone know how I could fix this issue

Thank you.
Eric

However, it has link error:

Hi @renyu_teng,

What verison of openNURBS are you using? I cannot tell if you are having problem building openNURBS or you solution that uses openNURBS? Can you clarify?

Hi Dale,

Thank you for your reply. I use the latest version downloaded from the web: opennurbs_6.1.18014.22401.

If I use the old version: opennurbs_20130711

Then I got the following error:

1>msvcprtd.lib(locale0_implib.obj) : error LNK2019: unresolved external symbol __imp__free_dbg referenced in function “public: static void __cdecl std::_Fac_node::operator delete(void *)” (??3_Fac_node@std@@SAXPEAX@Z)

Hi @renyu_teng,

With openNURBS 6, and using Visual Studio 2017, you should be able to open opennurbs_public.sln and build all configurations and platforms without error.

If you cannot, then you may not have all of the necessary C/C++ components installed. In this case, you should re-run the Visual Studio installer and add what you are missing.

thank you. I will revisit this issue again, but now the release build is good, and I can build the release version and it is good enough for me for now.

thank you again.
