Re: [Boost-users] Boost filesystem v3 with Qt.

Surya Kiran Gullapalli on 5. Juni 2011 21:04:

Hello, Sorry for cross-posting. I'm facing an issue with Qt (4.7.2, installed from Qt installer) with Boost.Filesystem v3 (1.46.1) on VS2008.

I'm facing linker errors with QString::toStdWString when /Zc:wchar_t is set

like this: unresolved external symbol "__declspec(dllimport) public: class std::basic_string,class std::allocator > __thiscall QString::toStdWString(void)const " [...] How can i use Qt with boost filesystem ?

Hello Surya, this really is a Qt issue. Using wchar_t as a native type you have to recompile Qt using the same compiler switch. There even is a bug in the tracker: http://bugreports.qt.nokia.com/browse/QTBUG-9617 In general, you will have to be very careful and do not mix wchar_t compiler settings in your projects as they will become incompatible.
