Visual Studio 2022 C++ MFC is not installing

underflow 0

I am having trouble in installing C++ MFC component on Visual Studio 2022 professional as well as community editions. It installs C++ MFC component. But if I check again, C++ MFC is unchecked in the install list checkbox. I did this several times. But still the same.

I need this to link Media Foundation lib files.

A shot in the dark here.
Have you selected the "Desktop development with C++" workload too?

I am trying to link a C++ DLL project with the following codes that uses Media Foundation. But I get link error with "LNK1104 cannot open file 'mfapi.lib'".

#include <stdio.h>
#include <windows.h>
#include <mfapi.h>
#include <mfidl.h>
#include <mfobjects.h>
#include <mferror.h>
#include <mfreadwrite.h>

#pragma comment(lib, "mf.lib")
#pragma comment(lib, "mfapi.lib")
#pragma comment(lib, "mfplat.lib")
#pragma comment(lib, "mfidl.lib")

To clarify, there are several different versions of MFC available to install. You need to install the right one.

Run the VS installer

Go to the Individual Components tab

Type in MFC in the search bar

Select `C++ MFC for latest v143 build tools (x86 & x64)

Install the components.

Then confirm the install.

Start Visual Studio

Create a new project

In the search filter type MFC

You should see several MFC templates available

I created using MFC project. But I still get the following link error: LNK1104 cannot open file 'mfapi.lib'". I use Media Foundation APIs. My code headings include the followings;

#include <windows.h> #include <mfapi.h> #include <mfidl.h> #include <mfobjects.h> #include <mferror.h> #include <mfreadwrite.h> #pragma comment(lib, "mf.lib") #pragma comment(lib, "mfapi.lib") #pragma comment(lib, "mfplat.lib") #pragma comment(lib, "mfidl.lib")

The libraries you mentioned are part of the Windows SDK, not MFC. There isn't an mfapi.lib that I'm aware of. The more recent libraries are just contained in: evr.lib, mf.lib and mfplat.lib. These are the libraries you'd link to. Assuming you're using the Windows SDK in your compiler settings then the libraries should be available.

Note that you are adding a #pragma to include them. Normally you just add them to your linker input settings so they are available for all your source files.

Please show us the function(s) you're trying to use and the actual linker error message.

Yes. It's win32 API. I think it's deplicated.

Hi, @underflow

Media foundation is Win32 library, not MFC.
There is no mfapi.lib and mfidl.lib.

mfapi.h -> Mfplat.lib

mfidl.h -> Mf.lib

mfobjects.h -> Mfuuid.lib

mfreadwrite.h -> Mfreadwrite.lib

Best regards,
