I've built ACE.dll and ACE.lib of the ACE library. But when I link it to my program, I get several errors like
Error 2 error LNK2019: unresolved
external symbol "void * __cdecl
ACE_OS::memcpy(void *,void const
*,unsigned int)" (?memcpy#ACE_OS##YAPAXPAXPBXI#Z)
referenced in function "public: void
__thiscall ACE_String_Base::set(char const
*,unsigned int,bool)" (?set#?$ACE_String_Base#D##QAEXPBDI_N#Z)
client_handler.obj Server
Error 3 error LNK2001: unresolved
external symbol "void * __cdecl
ACE_OS::memcpy(void *,void const
*,unsigned int)" (?memcpy#ACE_OS##YAPAXPAXPBXI#Z)
Server.obj
I've set include paths,lib paths, lib dependencies etc etc. I dont know what I'm missing :(
The linker is unable to find a definition for ACE_OS::memcpy. Check the documentation and see if you need to provide a suitable definition or not (or if there is one in the sample, if any samples are present at all).
This could also be because you've not defined a platform specific macro that would enable the default definition of this function. Please check the readme.

I had boost compiled & working on my Visual Studio 2022 project. After the PC was upgraded and the OS changed to Windows 11 I attempted to re-build boost and use it with the same project. Now I get linker errors, and it seems like I have tried every suggested fix posted online. Somehow it seems like the lib files are not being found, even though I have confirmed the include and lib directories are included properly, and have tried rebuilding boost with many different configurations.
The boost build produces libboost_*.lib files, for example
libboost_log_setup-vc143-mt-gd-x32-1_78.lib
libboost_log_setup-vc143-mt-x32-1_78.lib
libboost_log-vc143-mt-gd-x32-1_78.lib
libboost_log-vc143-mt-x32-1_78.lib
Here are my boost build options
x86
b2 -j 16 --stagedir=stage/Win32 threading=multi --toolset=msvc-14.3
link=static runtime-link=shared --build-type=complete architecture=x86
address-model=32
x64
b2 -j 16 --stagedir=stage/x64 threading=multi --toolset=msvc-14.3
link=static runtime-link=shared --build-type=complete architecture=x64
--address-model=64
And my Visual Studio properties
C/C++->General->Additional Include Directories
C:\Program Files\Code Libraries\boost\boost_1_78_0
Linker->General->Additional Library Directories
C:\Program Files\Code
Libraries\boost\boost_1_78_0\stage$(Platform)\lib
And here's an example of the errors
1>Logging.obj : error LNK2019: unresolved external symbol "private: static unsigned int __cdecl boost::log::v2s_mt_nt62::attribute_name::get_id_from_string(char const *)" (?get_id_from_string#attribute_name#v2s_mt_nt62#log#boost##CAIPBD#Z) referenced in function "public: __thiscall boost::log::v2s_mt_nt62::attribute_name::attribute_name(char const *)" (??0attribute_name#v2s_mt_nt62#log#boost##QAE#PBD#Z)

Edit: I also wanted to mention my preprocessor variables for Debug/Win32
WIN32
_DEBUG
_CONSOLE WIN32_LEAN_AND_MEAN
_WIN32_WINNT=0x0A00
I haven't been able to find a _WIN32_WINNT value for Windows 11, and I thought maybe that could be the problem. But I'm not entirely sure that matters.
The problem is that Boost, and Boost.Log in particular, was built for a different Windows version. You need to either:
Build Boost with _WIN32_WINNT defined to the same version as you define when you build your code.
Define BOOST_USE_WINAPI_VERSION when building your code to the Windows version Boost should target, which would be lower than your _WIN32_WINNT. Also define _WIN32_WINNT or BOOST_USE_WINAPI_VERSION macro to that version when building Boost.
To define the macro when building Boost add define=macro=value to the b2 command line. For example, define=_WIN32_WINNT=0x0A00.
I am using mfc class CImageList in my project and using its APIs like Add(), Create() etc. It works fine with vs2010.
Now, I am upgrading the project to vs2012. It compiles and links fine for 32 bit platform, however throws below linking errors for 64 bit.
File1.obj : error LNK2019: unresolved external symbol imp_ImageList_ReplaceIcon referenced in function "public: int __cdecl CImageList::Add(struct HICON *)"
File2.obj : error LNK2019: unresolved external symbol __imp_ImageList_AddMasked referenced in function "public: int __cdecl CImageList::Add(class CBitmap *,unsigned long)"
Similarly, below error is thrown for calling CBitmap api.
File2.obj : error LNK2019: unresolved external symbol __imp_CreateMappedBitmap referenced in function "public: int __cdecl CBitmap::LoadMappedBitmap(unsigned int,unsigned int,struct _COLORMAP *,int)"
It seems that the libraries having these implementations might have been changed. However, I could not find any clue on how to resolve them.
Finally figured out the reason for this error.
ImageList_ReplaceIcon & CreateMappedBitmap symbols are present in comctl32.lib.
There was an older version comctl32.lib present in a path which was included in Additional Include Directories of my project settings.
So, instead of picking this lib from Microsoft SDK folder, the linker was picking from this directory and hence causing problems.
I'm getting some unresolved externals when importing a DLL of a project (Project 1) in a .exe project (Project 2) using MSVC 2013 (it compiles fine in Mingw 4.8.1):
main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: class chakra::Message * __thiscall chakra::PublisherSubscriberChannel::GetMessageA(unsigned __int64)" (__imp_?GetMessageA#PublisherSubscriberChannel#chakra##QAEPAVMessage#2#_K#Z) referenced in function "public: virtual void __thiscall Bar2::ProcessMessages(void)" (?ProcessMessages#Bar2##UAEXXZ)
test_wrap.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: class chakra::Message * __thiscall chakra::PublisherSubscriberChannel::GetMessageA(unsigned __int64)" (__imp_?GetMessageA#PublisherSubscriberChannel#chakra##QAEPAVMessage#2#_K#Z)
The function GetMessage is a member function of class PublisherSubscriberChannel of namespace chakra in Project 1.
Examined the .exp and .dll file of Project 1 using dumpbin.exe /exports and found the function to be exported as ?GetMessage#PublisherSubscriberChannel#chakra##QAEPAVMessage#2#_K#Z whereas during importing it is looking for ?GetMessageA#PublisherSubscriberChannel#chakra##QAEPAVMessage#2#_K#Z as per the above error.
It happens only when I #include "Ogre.h" or any of the other Ogre headers in test_wrap.cxx file (which is a SWIG generated file).
Does anyone have any idea why the function name mismatch with the extra 'A'?
I'm trying to set up sound in my Ogre3D project. I have installed irrKlang 1.4.0 and added it's include and lib directories to my projects VC++ Include and Library directories, but I'm still getting a Linker error when I attempt to build. Any suggestions?
(Error 4007 error LNK2019: unresolved external symbol
"__declspec(dllimport) class irrklang::ISoundEngine * __cdecl
irrklang::createIrrKlangDevice(enum
irrklang::E_SOUND_OUTPUT_DRIVER,int,char const *,char const *)"

referenced in function "public: __thiscall
SoundManager::SoundManager(void)" (??0SoundManager##QAE#XZ)
Okay, after looking at this for awhile it seems I was making two mistakes.
The lib directory for irrKlang is divided in two, so instead of adding (IRRKLANGDIRECTORY)\lib to my library directories, I should have been using (IRRKLANGDIRECTORY)\lib\Win32-visualStudio.
Including the lib directory wasn't sufficient, I also needed to specify the use of the irrklang library file at the top of my class (#pragma comment(lib, "irrklang.lib")).
I'm writing a static library that uses PugiXml for xml parsing. Here is the linker output from Visual Studio 2010 (I've replaced the symbol with ellipses for readability):
error LNK2019: unresolved external symbol "public: __thiscall Dae_Library<class Dae_Geometry>::Dae_Library<class Dae_Geometry>(void)" (...) referenced in function "private: bool __thiscall Dae_Doc::ParseDae(void)" (...)

Things I've tried:
Explicitly instantiating my template class.
Linking PugiXml source in with test project (it is currently with the static lib I'm building)
Building PugiXml as a static lib and referencing it in both my lib project and the test project
Writing do nothing functions in place of my pure virtual functions.
Providing default constructors that do not reference pugixml at all
This has been driving me nuts for the past two days and I really have no idea what to do. If anyone can give me any direction at all I would greatly appreciate it!
Edit:
It's worth noting that creating a simple static library that uses pugixml compiles and tests fine, so maybe there is something wrong with how I've written my templates and classes?
From the error messages it looks like you're setting PUGIXML_WCHAR_MODE inconsistently.
It's likely that you're setting it in your project configuration, and using one of the bundled vcproj files from scripts/ folder inside pugixml distribution as is.
This define controls the type of character used in pugixml (char or wchar_t); you have to set it in the same way for both pugixml.cpp and the code that uses pugixml - it is recommended to either set it in pugiconfig.hpp, or to make sure that it's on in all projects that have source files that include pugixml.hpp. In your case, if you don't want to modify pugiconfig.hpp, you'll have to change the vcproj for pugixml static library.
