MSVC compile error after installed 5.10: 'QChar::QChar(ushort) noexcept':

[aha_1980]

Hi @VeNToR,

did you install all updates for MSVC 2015?

[VeNToR]

Yes, already installed.

[aha_1980]

@VeNToR then please show a minimal example that leads to this error. Thanks

[VeNToR]

You can see the error on minimal example.

Hi,

Are you modify the Zc compiler option in your project ?

[hskoglund]

Hi, also to add to @SGaist's question, do you get the same error when you compile in Release mode?

[VeNToR]

Thanks for everybody, I solved by create the solution again... Simple but takes a long time... Still I don't know why ?

[VeNToR]

@hskoglund Yes, I did.

[VeNToR]

@SGaist Yes, but not solved.

@SGaist I encountered the same problem with one of the static libraries I use, and the cause was indeed the Zc compiler option. In C/C++ →Language, the Treat WChar_t As Built in Type value must be set to Yes. Thanks for your help.

@xmichelo Thanks! This really helps!

@xmichelo, in my case, after setting WChar_t As Built in Type to Yes, i am not able to link to a 3rd party library anymore (xercesc).

With 5.9, i did not have such problem. Seems that something has changed between 5.9 and 5.10.

Now, i am facing errors like:

read_input_xml_options.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: static char * __cdecl xercesc_2_7::XMLString::transcode(wchar_t const * const)" (_imp?transcode@XMLString@xercesc_2_7@@SAPEADQEB_W@Z)

[VeNToR]

@eRic67 I solved the problem "re-create the solutions"... Stupid but %100 good solution !

@VeNToR What do you mean when you say "re-create the solution" ? I got the same problem here and I don't know how to fix it.
