I'm getting this error while trying to run sample codes in CUDA SDK. I have CUDA 2.3 and Visual studio 2008
LINK : fatal error LNK1181: cannot open input file 'cutil32D.lib'
Any pointers how to solve this?
Since you're compiling the SDK samples, the project files are probably correct. Far more likely is that you haven't built the cutil library. Go to the SDK install directory, then into the "C" directory. You'll see a "common" directory, in there open the cutil.sln solution (or cutil_vc90.sln for VS2008) and build it in release and debug modes for your platform.
Then try your sample again.
The cutil library is used to avoid replicating the same code through all the samples, if you're starting your own project I'd avoid reusing the cutil library and write your own checker. For example, you should probably fail gracefully if you detect a CUDA error rather than just calling exit() as done in cutil.
The cuda.rules file included in the SDK is highly recommended! Using this you can just add .cu files to any project and Visual Studio will know how to compile them and link them in to the final executable. Easy!
Your MSVC project needs to include the library cutil32D.lib to link. Once you specify it as a library the linker needs to include in the final binary artifact this problem will go away. It would seem the library is missing at the location the linker is going to look for it. You'll have to change the library search paths or move that file to a directory in which the linker is already looking.
I ran into the same issue. It turned out not only did I need to build the cutil project but also the shrUtils project under the SDK's shared folder.

I'm trying to compile the mysqlclient.lib library as a Multithreaded Debug DLL. I need it in this configuration to be able to link it to my project. To give some context I will explain what have I done so far:
I cloned the MySQL repository: git clone https://github.com/mysql/mysql-server.git
I created the MySQL.sln by running CMake.
I opened the solution in Visual Studio 2013 and built it with the Runtime Library setting equal to /MDd.
I have tried to link the thus compiled library mysqlclient.lib to my project(which is compiled with /MDd) but I'm still getting the error:
mysqlclient.lib(plugin_client.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.obj
I have run dumpbin /all mysqlclient.lib | find /i "mvscr" obtaining as a result /DEFAULTLIB:MSVCRTD which suggests that the library has been compiled as /MDd.
I have to admit that before wanting to link mysqlclient.lib to my project I was not even aware of the Runtime Library setting. At this point I don't completely understand why I'm getting the linker error above, which is why I wrote in the title that I think that the library is still getting compiled as /MTd. If anyone could point me to the right direction in order to solve my problem it would be very much appreciated.
EDIT
Reading better the MySQL documentation I found out that if my project is built as /MDd or /MD I have to link it to the libmysql.dll dynamic library. Section Compiling MySQL Clients on Microsoft Windows, second to last paragraph.

I'm trying to use the sqlite-winrt library at https://sqlwinrt.codeplex.com (cf. http://blogs.windows.com/windows_phone/b/wpdev/archive/2013/05/30/sqlite-winrt-wrapper-for-windows-phone.aspx) because I need to access an SQLite database via SQL commands in a WinRT 8.1 and a WP8 app and this library seems the only available option.
Anyway, there is no binary release and if I try compiling the source I get several link errors for unresolved externals against the SQLite DLL. I posted an issue at codeplex but got no reply yet, so I was wondering if anyone had already managed to successfully compile this lib and how (or if you know of any viable alternative for RT8.1 and WP8). Here is what I did:
downloaded the latest source from the site.
downloaded and installed 2 VSIX from http://www.sqlite.org/download.html: sqlite-winrt81-3080002.vsix for RT 8.1 and sqlite-wp80-winrt-3080100.vsix for WP.
executed the powershell scripts in each subfolder of the source code solution, which are required to update the projects with newer releases of the SQLite for WinRT extension. The current versions of the scripts refer to SQLite for WinRT 8.1 (prerelease) which is the same I downloaded above.
opened the VS2013 solution and removed the RT project (I just need RT8.1 and WP, this was for WinRT 8.0).
5) built the solution, which failed with link errors.
If I see the RT8.1 project properties, I can confirm the reference to SQLite is under C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1\ExtensionSDKs\SQLite.WinRT81\3.8.0.2.
Did anyone manage to use this lib? Thanks!
I also once had that problem. I fix it by editing the project file manually. At that time, the powershell script updating the wrong path. That's why I always failed when compiling my project. After I edit the project file using external text editor (I use sublime text), the projects are linked correctly.
You can try DatabasesCx. It is another SQLite Wrapper using Windows Runtime Component technology. It is freeware distributed as precompiled binary. You can find the details at http://www.almanacsoft.com/databasescx

I have faced with this problem. So many searching on internet but I could not find anything. At last I recognize that I closed Microsoft .NET Framework 3.5.1 features on Windows Features section in Control Panel.
to turn on Microsoft .Net Framework 3.5.1, you can easily follow these instructions;

I hope this solution will help you !
I've come across this problem after upgrading my system to windows 10. It turns out that I have to reinstall Visual Studio because some dependent dlls have been moved to Windows.old folder.
I had this same error when I was compiling on a remote server. I think it was because I was logged in using Remote Desktop (RDP). When I logged in using VNC and compiled, the error no longer happened.
Note that it's impossible to even install the CUDA Toolkit via RDP, so this is unlikely to happen, unless you regularly use both methods to connect to a server.
I compiled MySQL++ with no issues. When I launched some of the executables (resetdb.exe and simple1.exe) they suggest to run to test if the installation has been successful, the first error I got was that libmysql.dll was missing.
Adding its path to the PATH environment variable did not fix the problem, even after launching a new command prompt; I had to copy the DLL in the directory where MySQL++ executables are.
Now the DLL is found, but I get this error:
simple1.exe - Application error
The application was unable to start correctly (0xc000007b).
Click OK to close the application.
even launching from the command line, I get no more information than these.
Thank you for any help!
MySQL 5.5 -
MySQL++ 3.0.9 -
Windows 7 64 bits -
MINGW32 -
GCC 4.4.0
0xC000007B is a Windows error that means the executable is corrupted. It could refer either to simple1.exe or to one of the DLLs it's linking against.
Some reasons this could happen:
You're mixing toolchains in an incompatible way. In your case, you may have built simple1.exe using pieces built by MinGW GCC and pieces built by Visual C++. MinGW should be compatible with any pure C DLL built by Visual C++, including the MySQL C API DLL. However, you may have other pieces interfering. MinGW isn't compatible with VC++ at the C++ level, but then, it shouldn't have linked at all if this were your problem.
You didn't follow the MySQL C API import library build steps in README-MinGW.txt. You either missed a step, or skipped it entirely and are trying to use the import library that shipped with MySQL.
In your previous gyrations, you ended up with a corrupt object file, which got linked in. Try saying make clean all at the top level of MySQL++ to force a complete rebuild.
You're mixing versions of MySQL or MySQL++. If you have more than one version of each on the system, make sure you're consistent in their use. That is, build the C API import library from the same DLL you run the programs against, use exrun.bat to run the examples to ensure you're using the just-built version of the MySQL++ DLL instead of another you have in your PATH, etc.
Additionally, I note that you're using an older version of MySQL++. If you were on Linux, I could understand that as some distributions still ship with 3.0.9. But since you have to build MySQL++ from source with MinGW, I don't see why you're not using 3.1.0. Did you get a binary build from somewhere?
As for your PATH problem, did you restart the MinGW shell after doing this? PATH updates don't affect running programs; they keep the value they saw when they started.
I want to interact with a MySQL database from Matlab.
I found a mysql "library" for matlab here and the same on mathworks.
I followed the instructions to compile the library and the compilation seems to be successful. I get a mex32 file at the end. Only, the instructions on the first page refer to a Dll that I need to use (I guess that a Dll was supposed to be generated).
I am not familiar with the mex compiler or with compiling external modules for Matlab.
Am I missing something trivial? Where is the Dll supposed to be?
Thanks.
The reference to the dll is obsolete.
When you compile a mex function on Windows, you compile it as a dll (not an .exe). Thus, compiled mex functions used to have the extension .dll. Mex-functions with .dll extensions still work, but there is a warning that this might stop being the case in the future.
When 64-bit Windows arrived, TheMathWorks needed a way that people were to be able to compile the same mex-function for both Win32 and Win64, thus they changed the extension to .mexw32 and .mexw64, respectively. Apparently, they did not update the documentation completely.
I'd recommend using java to connect MATLAB and MySQL (or any other db if required).
The java database connector is simple to set up. I built a simple java class to connect to the database - see previous posting for a crude but working solution.
The MATLAB code works as indicated
% include java class
import Jam.ConnectToDatabase
% set up database connection info
userName='myName';
userPassword='myPassword';
databaseUrl='jdbc:mysql://glnd2818898.internal.net/2000';
% create java class instance and open connection to the database
ctd = ConnectToDatabase;
ctd.openConnection(userName, userPassword, databaseUrl)
Once the connection is open I can then use the java methods to submit SQL queries, create tables, insert data etc. I'd never used java before but I downloaded Netbeans and I was away.
OK, here is the solution to my problem.
The compilation does generate a mex32 file (32 is because I compiled it under a 32bit systme). You can check the output file of the compilation by running mexext. So apparently a mex32 file is a compiled version of the C file.
Once I placed the file in a directory that is in the Matlab's path it worked.
I guess the reference to the Dll in the link I provided is either obsolete or wrong.
