Not a library...probably a preprocessor directive?
From: LibreOffice [mailto:libreoffice-boun...@lists.freedesktop.org] On Behalf Of nicholas ferguson Sent: Sunday, September 28, 2014 7:19 PM To: 'libreoffice' Subject: which library needs to be linked to, that has implementation code for ErrorInfo::IsA My env. Cygwin + Visual Studio. Windows 7 (1) IsA in ErrorInfo comes from a macro in rtti.hxx a. /include/tools/errinfo.hxx i. class ErrorInfo has as member, macro TYPEINFO() to include 5 methods, including IsA b. /include/tools/rtti.hxx i. This has macros, including TYPEINFO c. Tools/ref/errinf.cxx ( implementation file, but does not include implementations for five methods via TYPEINFO macro. (2) What library needs to be linked to that has implementation code for macros in rtti.hxx for a Win32 Intel platform? Here is a test code //=========================================== #include "stdafx.h" #include <rtl/ustring.hxx> #include <include/tools/rtti.hxx> typedef void* (*TypeId)(); class ErrorInfoX { private: sal_uIntPtr lUserId; public: TYPEINFO(); ErrorInfoX( sal_uIntPtr lArgUserId ) : lUserId( lArgUserId ){} virtual ~ErrorInfoX(){} sal_uIntPtr GetErrorCode() const { return lUserId; } static ErrorInfoX* GetErrorInfo(sal_uIntPtr); }; int main(int argc, char* argv[]) { sal_uIntPtr t = 4; ErrorInfoX err(t); return 0; } //linked to lib(s) itl.lib ( tools ) /* error output: 1>testdefine.obj : error LNK2001: unresolved external symbol "public: virtual void * (__cdecl*__thiscall ErrorInfoX::Type(void)const )(void)" (?Type@ErrorInfoX@@UBEP6APAXXZXZ) 1>testdefine.obj : error LNK2001: unresolved external symbol "public: virtual bool __thiscall ErrorInfoX::IsA(void * (__cdecl*)(void))const " (?IsA@ErrorInfoX@@UBE_NP6APAXXZ@Z) 1>C:\cygwin64\home\lo\Excel.Analysis\Test.OpenClose\Debug\testdefine.exe : fatal error LNK1120: 2 unresolved externals */ //========================================================================
