Intro
I have a CMake-based C++ project. Until now I build and ran the project via CLion. Everything worked fine until I tried to run the .exe-file directly (not via CLion).
Problem
When I navigate to the cmake build directory in order to start my program via the executable file, it fails with the following message in the popup: Cannot continue the code execution because libgcc_s so-1.dll was not found. Reinstalling the program may resolve the issue.
I have the following questions
If I interpret the error message correctly, then this dll is missing on my computer. So I ask myself, why does my program still work when I start it via the development environment (CLion), although the error message expressly states that the source code requires this dll?
Is it the fault of my application/source code that the error appears or rather the current state of my computer? If the former, how can I prevent this error from appearing for other users?
What is the best way to fix this error? It's obvious that I need to download this dll, but where is the best place to put it (which directory and environment variable to use on Window)?
Which source is trustworthy to download this dll? I don't want to download any malware under this dll-name.
Optional: What kind of library is that? What functionalities does it offer?
Additional information
I use CMake as my build tool, CLion as the IDE and MinGW as the compiler.
What I have did so far?
I made sure it still works through the IDE.
I found this dll does not exist in the MinGW installation folder.
I searched the web for more information. Unfortunately, there are only pages unknown to me that only offer the download of this dll. That doesn't satisfy me.
I found the cause of my problem: I had two MingGW installations on my machine. Once the installation that comes with CLion and a separate one. The latter did not have the required dll. However, CLion used its own installation, which in turn owns the DLL. So the solution was to remove the separate installation and include the path to the CLion installation's bin/ directory in the PATH environment variable.
This file is part of MinGW-w64 when using SEH as exception model (as opposed to Dwarf or SJLJ). You need to distribute the .dll files your .exe file(s) depend on in the same folder as the .exe file(s).
If you don't have that file, then you probably have been using libraries compiled with different versions of GCC/MinGW(-w64). I recommend building everything with the same compiler to ensure stable binaries.
Tools like Dependency Walker can help you figure out which .dll files your .exe file depends on.
Or use the command line tool copypedeps -r from https://github.com/brechtsanders/pedeps to copy the .exe files along with it's dependencies.
I'm making a program using OpenCV and I need feature matching. I was previously using OpenCV3 but apparently getting SURF to work is a bit of a hassle so I switched to OpenCV2.4
I downloaded the pre-built libraries and I want to use them on Visual studio but I have a problem, when I run the program I get messages like this:
When I click ok I get more follow up messages complaining about other missing dlls. I tries re-installing but still get this error.
Here are my settings:

I've also tried editing the Environment Variables under Path I've added the include\ bin\ and lib\ directories. I have absolutely no idea how to fix this problem. I know the dlls are there.
I copied and pasted the dlls from the bin\ directory into my solution directory and everything works fine now.
I'm not sure why adding the bin\ to the path didn't work but anyway here's the solution to that problem.
The execution program did not find the DLL.
Under "Linker>General: Additional Library Directories" it expect the path for .lib files, but the DLL are searched by the program during the executio, so in the current folder and in the PATH folders.
Put the Dll's into the execution folder or modify the PATH to add the DLL's folder (in this last case remember to restart Visual Studio).

I have a C++ program that uses the freeglut library (and hence requires the freeglut.dll at run-time. I have added the folder C:\Program Files\Common Files\freeglut\bin to my PATH environment variable.
To confirm that the location is correct, when I compile my program (debug build) and run the resulting .exe file, it works fine (the freeglut.dll file is not in the same directory as the executable).
However, when I run the program directly from the VS2012 debugger, I get this message:
The program can't start because freeglut.dll is missing from your computer. Try reinstalling the program to fix this problem.
I know that one solution is to place the freeglut.dll file in the directory of the executable. This is what I've been doing so far, but I would much rather simply inform VS2012 (or my program) of where to find the dll file. Note that this post also seems loosely related, but it doesn't seem to contain an answer relevant to what I am trying to achieve (I just want the debugger to look in the same place for DLLs as any other program!).
How do I achieve this in VS2012? Icing on the question cake would be an explanation as to why the debugger doesn't just look in the PATH variable like any other program...
You can also set project based Environment:
Open project Properties
Go to Configuration Properites -> Debugging
Enter the path in Environment, eg:
PATH=$(PATH);C:\Program Files\Common Files\freeglut\bin
Restart Visual Studio after modifying your PATH variable.
What I did actually worked. I just didn't restart VS...
I'm trying to compile a SDL-program I've written, but when I do, this error shows up:
The program can't start because SDL.dll is missing from your computer.
Try reinstalling the program to fix this problem
I have no idea as to why. I have SDL.dll.
I have put it in the correct folder: C:\Windows\System32.
I have the correct PATHS to all the SDL headers and such as well.
VS says:
Build succeeded: 1
and THEN the error above pops up on screen.
Add it into your debug folder or whatever directory your program is currently located at.
SDL.dll has to either be in the same directory as your application, or in a directory that's in the PATH environment variable.
IfSDL.dll is 32-bit and you're running a 64-bit system you have to place the dll into /Windows/SysWOW64/ rather than /Windows/System32/, which is used for 64-bit dlls.
EDIT:
You probably shouldn't be deploying your DLLs by copying them into the System32 directory, unless they're common libraries that are used by several applications, and even then I would use discretion. For example, an application could update the DLL, which could break other applications that rely on an older version of the library.
Instead, copy the DLLs into the same directory that the executable is being built in. If you're building and executing with Visual Studio it will look for the DLL in the Project directory, where your source files are probably located.
Just place your SDL.dll in the same folder and your problem will be solved.
And to answer to your problem with the PATH, you can specify in visual studio where he will look for executables while debugging. Maybe this isn't set correctly and that's why VS can't find SDL.dll?
I am trying just a basic program with OpenCV with the following code:
#include "cv.h"
#include "highgui.h"
int main()
{
IplImage* newImg;
newImg = cvLoadImage("~/apple.bmp", 1);
cvNamedWindow("Window", 1);
cvShowImage("Window", newImg);
cvWaitKey(0);
cvDestroyWindow("Window");
cvReleaseImage(&newImg);
return 0;
}
When I run this, I get
The program can't start because
libcxcore200.dll is missing from your
computer. Try reinstalling the
program to fix this problem.
However, I can see this DLL. It exists. I have added the following to the input dependencies for my linker
C:\OpenCV2.0\lib\libcv200.dll.a
C:\OpenCV2.0\lib\libcvaux200.dll.a
C:\OpenCV2.0\lib\libcxcore200.dll.a
C:\OpenCV2.0\lib\libhighgui200.dll.a
What gives? I'm using visual studio 2008.
When I link the .dll files instead of .dll.a files, I get
fatal error LNK1107:invalid or corrupt
file: cannot read at 0x3F8
libcv200.dll
I followed instructions on http://opencv.willowgarage.com/wiki/VisualC%2B%2B_VS2010 but was still stuck on exactly the same problem, so here's how I resolved it.
Fetched MSVC 2010 express edition.
Fetched Win 32 OpenCV 2.2 binaries and installed in default location.
Created new project.
Project setup
Project -> OpenCV_Helloworld Properties...Configuration Properties -> VC++ Directories
Include Directories... add: C:\OpenCV2.2\include\;
Library Directories... add: C:\OpenCV2.2\lib;C:\OpenCV2.2\bin;
Source Directories... add:
C:\OpenCV2.2\modules\calib3d\src;C:\OpenCV2.2\modules\contrib\src;C:\OpenCV2.2\modules\core\src;C:\OpenCV2.2\modules\features2d\src;C:\OpenCV2.2\modules\flann\src;C:\OpenCV2.2\modules\gpu\src;C:\OpenCV2.2\modules\gpu\src;C:\OpenCV2.2\modules\highgui\src;C:\OpenCV2.2\modules\imgproc\src;C:\OpenCV2.2\modules\legacy\src;C:\OpenCV2.2\modules\ml\src;C:\OpenCV2.2\modules\objdetect\src;C:\OpenCV2.2\modules\video\src;
Linker -> Input -> Additional Dependencies...
For Debug Builds... add:
opencv_calib3d220d.lib;opencv_contrib220d.lib;opencv_core220d.lib;opencv_features2d220d.lib;opencv_ffmpeg220d.lib;opencv_flann220d.lib;opencv_gpu220d.lib;opencv_highgui220d.lib;opencv_imgproc220d.lib;opencv_legacy220d.lib;opencv_ml220d.lib;opencv_objdetect220d.lib;opencv_video220d.lib;
At this point I thought I was done, but ran into the problem you described when running the exe in debug mode. The final step is obvious once you see it, select:
Linker -> General ... Set 'Use Library Dependency Inputs' to 'Yes'
Hope this helps.
Just add C:\OpenCV2.0\bin into your PATH environment variable
or
When you install OpenCV,
Choose the option, Add OpenCV to the system PATH for current user which is not default one
Just for your information,after add the "PATH",for my win7 i need to reboot it to get it work.
In Visual Studio 2013 you need to add this to the Environment Variables and then Restart your pc. This is the path where .dll file located in.
I have had numerous problems with opencv and only succeded after a gruesome 4-6 months. This is the last problem I have had, but all of the above didn't work. What worked for me was just copying and pasting the opencv_core2*.dll (and opencv_highgui2*.dll which it will ask for since you included this as well) into the release (or debug folder - I'm assuming. Haven't tested this) folder of your project, where your application file is.
Hope this helps!
You just need to add the folder of the needed dll file (or files) to your system "Environment Variables" in "Path".
Your problem will 100% be resolved. I had this problem too.
just open the bin folder and copy and paste the .dll files to the folder you are working in..it should fix the problem
As to #Marc's answer, I don't think VC uses the path from the OS. Did you add the path to VC's library paths. I usually add the DLLs to the project and copy if newer on the build and that works very well for me.
you can find the opencv_core248 and other dlls in opencv\build\x86\vc12\bin folder. Just copy the dlls you require into system32 folder. And your app should start working in a flash ! Hope it helps.
This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.
It's actually best practice to provide the os with a path link.
With windows 10
open up file explorer
right click on "this pc" and select "properties"
Now in the "Control Panel\System and Security\System" window that comes up, click on "Advanced System Settings" from the left hand panel.
At the bottom of the next window, click on the "Environment Variables" button.
On the next window, there are two panels, the top one is for modifying variables to the current user, and the bottom panel is for modifying variables to the system. On the bottom panel, find the variable "Path" and click it to select it, then click on the "edit" button.
Here you can then create, edit, delete, or update the different paths for the system. For example, to add mingw32-make to the system so you can access that command via command prompt, click new, then paste in the path to the bin. Example path, "D:\Qt\Tools\mingw730_64\bin", no quotation marks nor additional whitespaces.
Click ok on all the windows so that the changes are saved, then reboot your computer for the changes to be loaded.
The ".a" at the end of your DLL files is a problem, and those are there because you didn't use CMAKE to build OpenCV 2.0. Additionally you do not link to the DLL files, you link to the library files, and again, the reason you do not see the correct library files is because you didn't use CMAKE to build OpenCV 2.0. If you want to use OpenCV 2.0 you must build it for it to work correctly in Visual Studio. If you do not want to build it then I would suggest downgrading to OpenCV 1.1pre, it comes pre-built and is much more forgiving in Visual Studio.
Another option (and the one I would recommend) is to abandon OpenCV and go with EmguCV. I have been playing with OpenCV for about a year and things got much easier when I switched to EmguCV because EmguCV works with .NET, so you can use a language like C# that does not come with all the C++ baggage of pointers, header files, and memory allocation problem.
And as for the question of 64bit vs. 32bit, OpenCV does not officially support 64bit. To be on the safe side open your project properties and change the "Platform Target" under the "Build" tab from "Any CPU" to "X86". This should be done any time you do anything with OpenCV, even if you are using a wrapper like EmguCV.
Copy all .dll from /bin in System32
Just copy the .dll files to C:\windows\system32\
No need to do any of that. It is a visual studio error.
just go here:
http://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=31354
and download the appropriate fix for your computer's OS
close visual studio, run the fix and then restart VS
The code should run without any error.
