My code compiles correctly but when I start without debugging it gives the following error:
pmdaccess2.dll is missing
I have provided the link to this dll in the Linker->general section however I get this error. Any idea why this is happening and how to fix it?
I am using Visual Studio 2015 64bit in Windows 10 and my PMD camera is connected to USB3.
A dynamic library is linked to at runtime. The library needs to be located in the same directory as the executable or in a directory specified in the PATH environment variable.

I've recently decided to try out PostgreSQL as the database platform for some C++ development I'm working on. I decided to use libpqxx as the connection library for my project, and quickly found out this would be an uphill battle to do from VS 2015 on a Windows 10 machine.
After much teeth-gnashing and nail-biting, I have gotten libpqxx to compile on Windows 10.
This leaves me with the following directory structure
Per libpqxx's documentation, I also placed a copy of libpq.dll in my project's executable directory. Please note: I have done this for both debug and release builds, tried to build both, and ended up with the same result.
All the tutorials I've seen seem to indicate that the library can be used after linking it and simply #including pqxx/pqxx, so I set up a small project to do just that. I receive the error:
fatal error C1083: Cannot open include file: 'pqxx/pqxx': No such file or directory
When attempting to build the project. I have also tried this will both debug and release builds, to no avail.
Here is a screenshot of my linker settings.
Does anyone have any suggestions for how I might be able to link and use this library from Visual Studio 2015?
As Sami Kuhmonen pointed out, this was not actually a linker error, but a compiler error. I needed to include an actual header, which Visual Studio needed to be able to find. After adding the correct folder (C:\libpqxx\include in my case) to Visual Studio's "additional include directories" setting under C\C++ -> General per drescherjm's suggestion, the program compiles just fine.
For future reference:
I did also run into unresolved external linker errors after solving the initial issue. This is because you need to make sure to also link to ws2_32.lib and libpq.lib. You also need to copy some other DLL files that libpq also relies on into your libpqxx lib folder. On my system, I believe these were ssleay32.dll, libeay32.dll, and libintl-8.dll. These files reside under the root of the PostgreSQL install. The DLL step is mentioned under libpqxx's INSTALL.txt file, however I believe it stated that the DLLs resided one folder under where I actually found them.
I have also faced same issue. Then I realized that I was building ,my application as a 32bit. I changed the target to x64 and it compiled successfully
I have environment where both VisualStudio 2005 and VisualStudio 2013 are installed. And I have strange situation with some of the projects. I compile such projects with VS2013 and when I try to launch them through Explorer or command line I get an error - "The program can't start because MSVCR80.dll is missing ...". Why msvcr80 when I compile with msvcr120?
What I tried:
Put msvc*80.dll to directory with executable. I got runtime error "R6034. An application has made an attempt to load the C runtime library incorrectly..."
Checked binary dependencies with Dependency Walker. I saw that binary has dependencies to VS2013 runtime, and there is no mention about msvcr80.dll
Launched binary with empty PATH. I gave no positive effect.
Launched binary on another 'clean' pc. And it worked all right with vs2013 runtime.
How can this be?
Thank you for all, you was right. I just forgot, that I have installed old version of my product. It was launched in background and used old versions of libraries. So when I ran my new application it tried to use libraries that already had beed loaded. In another way Dependecy walker didn't check already loaded libraries and looked only in PATH.

I cloned a project from github to my computer and I'm trying to compile it but I'm getting a crazy amount of errors regarding references to libraries and stuff. I uploaded the project from another computer and it works just fine in that computer. Here are the errors I'm getting:
There are more errors but these are enough. As you can see the issue is within the included libraries (which are static), so I'm not sure what I'm missing here, because the linking to the wininet library and such are fine.
Maybe its an inconsistency between x86 and x64? I dunno.
The path to the c++ compiler:
C:\Program Files
(x86)\mingw-w64\i686-5.2.0-win32-dwarf-rt_v4-rev0\mingw32\bin\c++.exe
Path to library
C:\Program Files
(x86)\mingw-w64\i686-5.2.0-win32-dwarf-rt_v4-rev0\mingw32\include\wininet.h
I followed these steps to configure this environment:
-Downloaded netbeans
-Downloaded mingwin
-Downloaded msys
Its weird because when ctrl + click the wininet.h and variable types and everything it directs me to where they're declared, however the environment can't locate them.
If you need more information please tell me.
Thanks!
There's no such thing as "the WinInet" library that you can download. This is all part of the Windows SDK. LPVOID for instance is defined after you include <windows.h>
I've recently downloaded Assimp and I've run into some troubles.
I've linked the libraries and I can get the program to compile and it runs fine in Release mode; however, the Debug .exe hits me with this error:
The application was unable to start correctly (0xc0150002). Click OK to close the application.
Some more details:
I'm using VS2010 with Target Machine set to x86.
I am using the 32bit debug dll (Assimp32d.dll) that was provided, and I've tried setting runtime libraries to /MT, /MTd, /MD, and /MDd with no luck.
I read from other similar threads that I should run Dependency Walker on the .exe, but I'm not sure what the output means. I'll paste it here if this helps you guys.
Error: The Side-by-Side configuration information for "c:\users\-----\documents\visual studio 2010\projects\AssimpTest\debug\ASSIMP32D.DLL" contains errors. The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail (14001).
Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Rather than rebuilding the libraries, I downloaded a different set of libraries (it was the SDK installer) and the debug dll's from that are working perfectly.
Just in case anyone has the same problem with the same software, this was the exact name of the installer that worked for me: assimp-sdk-3.0-setup.exe
I ran into the same problem when trying to run a 64-bit project in Debug mode when using Assimp 3.0.
What I did was go to assimp/workspaces/vc9, open assimp.sln in Visual Studio 10, convert the project, then rebuild the 32 and 64-bit dll.
Mind you, you've got to install boost for that as well, and edit the project properties so it points to the boost directory for includes.
There's probably a way to do it using CMake as well, but I found the whole process too cumbersome to bother with in the first place.
My solution was just to link the debug build to the release .dll files. No more issues, and I wasn't that interested in debugging the Assimp library anyway!
I faced the same issue, later on I downloaded the "assimp-sdk-3.0-setup.exe" file & installed it as a standard windows application.
I pointed Visual Studio Solution Include & Lib directories to respective folders from newly installed location, copied DLL to my application location. The problem was resolved. Hope this helps someone.
Cheers.
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?
