How do I make a fully statically linked .exe with Visual Studio Express 2005?
(4 answers)
Closed 6 years ago.
When I run my program on a freshly installed computer, it tells me that Visual C++ Redistributable Package 2015 (namely, MSVCP140.dll) needs to be installed on the computer in order to run my dynamically linked program.
I understand that static linking would solve the problem - however, that just doubles the size of my executable.
Isn't there a way to suppress visual studio features so the redist package is not necessary and still use the visual studio compiler, as I'm not used to the alternatives like mingw etc.
Or does the redist package actually contain the STL? I can hardly imagine that.
AFAIK you only have 2 options :
1. static linking - no dll dependency, but huge size
2. dynamic linking - you need correspond dlls , relativelly small executables.
As for #2 you also have 2 options :
install redist as standalone package
put this dll's in same directory with exe . It's "legal"
from MS stand point. (privat assembly ?)
Hope it helps .
The 'redist packages' contain basically the libraries. If you don't use any library functionality, you will not need them, but otherwise there is no way - you can't call a library function and then don't have it.
That means remove all includes with <>, and you are good.
Note that if you do use library functions, that is hardly an option - you really don't want to recode strlen, fopen, and so on yourself.

Problems with running EXE file built with Visual Studio on another computer
(6 answers)
Closed 2 years ago.
I am new to C++ and recently made a Tic-Tac-Toe game, which is a console application (no graphics). I have built my project in Release mode in Visual Studio 2019. I want this application to be transferred from one computer to another. I have zipped the Release folder of Visual Studio and tried to transfer it into another PC. When I ran it on another PC it failed to work?
I am new to programming, please help.
You don’t mention the exact error, but a first order possibility is a missing dependency.
Odds are you are missing the Visual Studio C++ runtime on the target machine (the one you are coping to). Windows does not install them by default, but Visual Studio does install them.
To download the runtime, go to https://visualstudio.microsoft.com/downloads/ then navigate to “Other tools and frameworks” then “Microsoft Visual C++ Redistributable for Visual Studio“. Select the version that matches your build and download and install it. You can copy the runtime dlls over from your PC, but installing them is generally easier and better for maintenance. If you are using an older version of Visual Studio, the download is normally available, but you’ll have to search for it.
Failing that, you may have another dependency missing. You should look to tools such as Dependency Walker, still available here https://www.dependencywalker.com/.
It must be run on pc's which OS you built on if it doesn't have additional libraries (Not Standart). if you have additional libraries, Add .dll files into release folder.
If you need help on customizing Console, I'll glad to help you on this.

Visual Studio 2017 C++ Exe for any pc (linking vcruntime140.dll)
(2 answers)
Closed 2 years ago.
I have written a C++ project using Visual Studio 2017 in Windows 10. I am trying to run the code in other computers as well.
So, I tried copying the Release folder to another Windows 10 computer. But, when I try to execute the .exe file, it is showing errors: missing dll’s: vcruntime140.dll and ucrtbased.dll.
Please help me in the release process to be followed.
The reason is because your application is dynamically loading the VC runtime which gets installed with the Redistributable package. Typically people can install the Redistributable packages without the full SDK but the easier solution is to just compile your application to statically load the C runtime libraries.
Go to project settings, then C/C++->Code generataion and change your runtime library from /MD to /MT. /MD is dynamic and /MT is static.
Also you can just install the package on your other machine from here https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

MSVCP140D.dll missing, is there a way around? [closed]
(2 answers)
Closed 3 years ago.
I'm coding a native C++ application in Vs 2019 that sould be able to run on a freshly configured windows 10 machine.
The problem is that when i run my .exe app on this machine i get missing dlls error such as MSVCP140D.DLL, VCRUNTIME140D.dll etc.
I tried to install the vcredist from MSDN on the guest machine and i also tried changing the "runtime library" from the "code generation" module in the project config.
I also followed some other tutorials that i've read on this platform but i can't find nothing that really works.
I even tried to place the missing dlls in the same directory of the .exe file to register them manually, actually it does not work, but this app i'm developing should be redistributable so the user should have just to execute it.
If i try to compile my program with another compiler such as MinGw it works but i wanted to use the vc++ default compiler if possible.
Is there a way to solve this issue?
Thanks!
Maybe you used MSVCP140.DLL, wihtout the D. the D stands for DEBUG and I don't know if the Debug version version comes with the visual studio redistributable. If you compile in visual studio try to build the Release version, this should work with the DLL´s from the redistributable
My application when opened in others computer will give an error missing msvcr"something".dll, I found out that to fix this they need to install the following:

Which is Visual C++ Redistributable Packages for Visual Studio 2013.
I would like to compile the program with the dlls in the executable already, is such thing possible?
If not possible, where can I get all the dlls to put in the compiled project folder?
Try to set /MT for Release and /MTd for Debug in Project Settings->C/C++->Code Generation. This will make your program not dependent on Visual Studio libraries. But beware that all the libraries/ projects you will link with should also have the same option there, otherwise you'll get nasty linker errors.
You may also wish to select v120_xp in General->Platform Toolset for your program to be able to run on Windows XP
Because a lot of Programms use the functionality of these dll's they are dynamically linked.
So your filesize stays small and in case of fixes within the dll you dont have to recompile your program.
If you dont want this behaviour you can set in the projectsettings the dll's to "static linked" (/MT).
That way they will be compiled into your executable
Here is a relevant MSDN-article
Which is Visual C++ Redistributable Packages for Visual Studio 2013.
For Visual Studio 2013, you need:
http://www.microsoft.com/en-us/download/details.aspx?id=40784
If you were building with Visual Studio 2012, then you would need:
http://www.microsoft.com/en-us/download/details.aspx?id=30679
If you were building with Visual Studio 2012, then you would need:
http://www.microsoft.com/en-us/download/details.aspx?id=5555 (x86)
http://www.microsoft.com/en-us/download/details.aspx?id=14632 (x64)
The point is, you are probably going to need a runtime if you are writing portable C/C++ code by using functions like new, malloc, delete, free, etc.
You might be able to avoid the code if you use the Win32 API. For example, HeapAlloc and HeapFree, etc. Installers often use the Win32 API, and that's one of the reasons they usually don't need a runtime installed prior to running them.
I would like to compile the program with the DLLs in the executable already, is such thing possible?
Yes, its possible. Its called Static Linking (as opposed to Dynamic Linking).
But you will probably still need a runtime.
If not possible, where can I get all the DLLs to put in the compiled project folder?
Retired Ninja gave you this answer: Microsoft Visual Studio ~ C/C++ Runtime Library ~ Static/dynamic linking.
My application when opened in others computer will give an error missing msvcr "something".dll" ...
Another possible solution is to build your project with Visual Studio 2005 or Visual Studio 2008. The runtime used by VS2005 and VS2005 are usually available on Windows Vista, Windows 7, and Windows 8. So the computer may already have them.
But usually you just build your installer to carry around what you need. I use Inno Setup because it allows you to include both x86 and x64 components side-by-side. At install time, you just install the right components based on architecture (x86 vs x64), including the correct runtime. (At the time I choose Inno, Wix did not allow mixing architectures and I wanted a unified installer).
I'm writing a DLL for a very old program that was compiled using Visual Studio 6. This program exports some functions that return pointers to standard library containers, and I'm (unsurprisingly) running into problems when I attempt to do anything with them from my DLL, which is compiled under VS 7. The source code for the program isn't available, so recompiling it with VS 7 isn't an option.
Is there any way I can reconfigure VS 7 to link against the import libraries from the VS 6 CRT? I do have VS 6 installed (and thus all the necessary .libs and headers), but I would much rather use a newer IDE. I've tried checking "Ignore Default Libraries" in VS 7 and adding the VS 6 lib/include paths to the project settings, then adding MSVCPRT.LIB to the additional dependencies, but I just get a ton of unresolved externals from the CRT when I build the project.
Thanks a lot!
This might help.
The CRT and STL were both majorly revised between VS6 and VS7. If you can make this really work, I would be surprised.
I would probably build a "wrapper" module in VS6 that exposes the data in a more neutral way.
