I have installed visual studio 2012 on 64 bit windows 7, and trying to build MFC Project, but on first debug always appear error:
Error 1 error C3861: '_T': identifier not found c:\program files (x86)\microsoft visual studio 11.0\vc\atlmfc\include\atlexcept.h 66
Error 3 error C3861: '_T': identifier not found c:\program files (x86)\microsoft visual studio 11.0\vc\atlmfc\include\atlcomcli.h 556
Error 4 error C3861: '_T': identifier not found c:\program files (x86)\microsoft visual studio 11.0\vc\atlmfc\include\atlcomcli.h 589
...
Where those _T macro have to be define? Why those problem appear?
#include <tchar.h> should work. If it is not.. Then try to do this ;
#ifdef _UNICODE
#define _T(x) L ## x
#else /* _UNICODE */
#define _T(x) x
#endif /* _UNICODE */

The errors might be showing because of the internal thing I had created and defined as static

The rest of the code is just warnings about int to float conversions:
I am not to skilled in programming and I am also following a tutorial however though I believe I had defined a macro variable for the static keyword called #define internal static however this had caused errors due to the files I was talking about(Xiobase, xlocnum, io) containing a keyword named internal thus causing errors because of the two variables with different meaning having the same name the program was confused.
I was playing with VS2019 and found out that it works with clang. So I installed clang and I've been having some issues with it working with VS2019. However, this issue is only based on the compiler. Seems that if I were to compile with the command line:
C:\Program Files\LLVM\msbuild-bin\cl.exe /std:c++17 source.cpp
Where source.cpp contains:
#include <tuple>
#include <iostream>
void fn(int x)
{
std::cout << x << std::endl;
}
int main()
{
std::tuple<int> x(1);
apply(fn, x);
return 0;
}
It barfs up:
clang-cl.exe: warning: argument unused during compilation: '/std:c++17' [-Wunused-command-line-argument]

However, if I use:
"C:\Program Files\LLVM\bin\clang-cl" /std:c++17 source.cpp
All is well.
Thing is, VS2019 is using the former compiler executable. How do I get it to use the latter?
The only thing I did to change the builder was to go and change this item:
Is there anything else I am to be changing?
I recently created a VS2015 solution to continue development on a C++ project I had been working on. Whenever I try to build the project, I get hundreds of errors from standard C library header files such as string.h, stdio.h, etc.
To try to get to the root of the problem, I created a new, very basic, VC++ win32 console application project, wondering if I'd see the same compiler errors. Here is the code (ConsoleApplication1.cpp):
#include <string>
#include <iostream>
int main()
{
std::string s = "some data to print...";
std::cout << "Printing: " << s.c_str() << std::endl;
return 0;
}
When I attempt to compile this, I get 150+ errors, like this:

I have tried to 'repair' Microsoft VC++ 2015 Redistributable(x86) via the Windows 'Uninstall or change a program' utility, to no avail. I also tried to repair Visual Studio 2015 as a whole.
I'm on Windows 7.
Anyone have an idea what is going on here? Am I pointed to the wrong include directory or something?
It appears you have (some of) the headers from a previous version of VS installed in your VS2015 folder. The standard headers in VS2015 are stored off in a folder tied to the version of the CRT (something like c:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt). Repairing or reinstalling VS2015 won't fix this.
I think you'll need to uninstall VS2015, completely delete the folder C:\Program Files (x86)\Microsoft Visual Studio 14.0, then reinstall it. This will likely break the other version (VS2013?) that is installed there, so you might want/need to uninstall that version instead, then repair VS2015.
The header that comes with VS2015 does not appear to have the "int _CRTIMP_ALTERNATIVE" listed in some of the error messages at those lines, while the one with VS2013 does.
In VS2013 Community Edition, I had a Win32 VC++ clr project I've been working on. I'm trying to use the CefSharp library, and so through nuget I've imported it.
Following the steps found here I learned I had to change from Win32 to x64 as my 'Active solution platform' to avoid this:
error : CefSharp.Common does not work correctly on 'Win32' platform. You need to specify platform (x86 / x64).
However when I follow those steps and add x64 to my project through the configuration manager, I get the following compilation errors:
1>------ Build started: Project: PROJECTNAME, Configuration: Release x64 ------
1> Main.cpp
1>C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\system_error(20): error C2869: 'std::errc' : has already been defined to be a namespace

1>C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\system_error(101): fatal error C1903: unable to recover from previous error(s); stopping compilation
I'm not sure what is causing this or how to solve it.
Edit: unlike the case in the question noted in the vote-to-close, the offending code here is CRT code, not mine. Even if it has a problem (which I'm pretty sure it doesn't), I have no way of fixing its source.
We have some legacy memory-leak tracing code that uses some CRT internals (nothing too exotic, essentially _CrtMemBlockHeader which is sort-of documented). While trying to migrate from VS2010 to VS2013 the code seems to cause sporadic build failures, and the offending part can be reduced to this:
#include <windows.h>
#define _CRTBLD
#include <..\crt\src\dbgint.h>
#include <fstream>
void Func()
{
std::ofstream myfile;
myfile << 8;
}
I.e., these 10 lines alone builds fine in VS2010 and in VS2013 give:
c:\program files (x86)\microsoft visual studio

I suspect the error message is not accurate - there are indeed several potential definitions of id, none of them at line 1105. There is also a considerable spew of warnings:

For now I'm pasting the definitions of _CrtMemBlockHeader and some macros around it directly to my code. But still - can anyone see what broke?
I realize it is not fully supported, but one can hope: is there a more robust way of using _CrtMemBlockHeader?
Looking at this error on my system, it seems to be only related to the #define _CRTBLD and the fstream header. The included dbgint.h is irrelevant (you can comment out that #include and still get the same error.
So, this seems to be a problem in the fstream header. Changing the order of inclusion removes the compilation errors:
#include <windows.h>
#include <fstream>
#define _CRTBLD
#include <..\crt\src\dbgint.h>
Perhaps this helps?
