protoolkit_NU.lib(srcstdstream.obj) : error LNK2019: unresolved external symbol __std_find_trivial_1

Hello,

I'm trying to build a Project, wherein i get the below compilation error: Not sure where exactly is going wrong.

>protoolkit_NU.lib(srcstdstream.obj) : error LNK2019: unresolved external symbol __std_find_trivial_1 referenced in function "unsigned __int64 __cdecl std::_Find_elem<char,27>(char const (&)[27],char)" (??$_Find_elem@D$0BL@@std@@YA_KAEAY0BL@$$CBDD@Z)

Settings Done on Visual Studio 2019:

1. Added protoolkit_NU.lib in Linker->Input->AdditionalDependencies

2. Added "$(CREO_INSTALL)/otk/otk_cpp/x86e_win64/obj;$(CREO_INSTALL)/protoolkit/x86e_win64/obj;" under Linker->General->AdditionalLibraryDirectories

Can you DM or attach your *.vcxproj file?

I have already developed a couple of Toolkit projects and if you want, I can check your Visual Studio Project file with one of mine to see if all necessary properties are present in the *.vcxproj file (because in the beginning I was also struggling with compilation/library errors)

I solved the issue. It was related with new version of VS2022 to be used for building the solution, as it was dependent on V143 toolset.

Thanks much for the reply.
