I downloaded eclipse-juno, and run it. It was giving error as " A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:
C:\Program Files\eclipse\jre\bin\javaw.exe javaw.exe in your current PATH "
Then I set environment variables as told in this post
Eclipse - no Java (JRE) / (JDK) … no virtual machine.
Now its giving error
Failed to load the JNI shered library "C\Program Files\Java\Jdk version\bin\...\jre\bin\client\jvm.dll"
First of all make sure your Java and Eclipse have the same architecture - they both have to be either 32-bit or 64-bit. If that checks out, it should be OK.
I had the same problem: in my case everything was in fact 64-bit - 64-bit OS, 64-bit Eclipse and 64-bit JRE in use, so there was some confusion as to the origins of the issue...
What helped was correcting environmental variables JAVA_HOME and PATH - and pointing them directly to the bin catalogue:
.../My/Java/Location/bin
instead of
.../My/Java/Location
Possibly you have installed wrong BIT version of Java on your machine. If your machine is 64 bit, you might have installed 32 bit java only. You can able to view whats your machine architecture by right clicking on computer and say properties.
If your machine is 64 bit machine. Install 64 bit Java, 64 bit Eclipse. Make sure your classpath is set
Hope this will help.
You can test this solution, maybe works: go to window->preference->server->runtime environments->and set your server path Example: tomcat path.
for set java invironment variable and classpath:try like this:
and in path section:

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.
When I try to configure my Hudson job to use polling against my Sourcesafe repository, I get the following error :
com4j.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform
How can I resolve this?
Source: credit to Allen at hudson-ci.org
What's happening here is that Hudson is trying to use the 32-bit dll from a 64-bit Java process.
To resolve this, simply either configure Hudson to run exclusively using a 32-bit version of the JRE, or just uninstall your 64-bit java runtime and replace it with a 32-bit runtime (don't forget to update your %PATH% values pointing to the JRE!).
Once this is done, the error should be resolved.
I'm trying to setting up a mySql connection using Matlab, I have read I few tutorial but unfortunately I can't get work of them. I had tried to compile the source(.cpp) but I got the following error:
Error: Could not detect a compiler on local system
which can compile the specified input file(s)
C:\PROGRA~1\MATLAB\R2010B\BIN\MEX.PL: Error: No compiler options file could be found to compile source code. Please run "mex -setup" to rectify.
So I I typed "mex -setup"
Please choose your compiler for building external interface (MEX) files:
Would you like mex to locate installed compilers [y]/n? y
Select a compiler:
[0] None
Compiler:
but there is no compiler.
Anybody can help me, how can I make a connection between matlab and mysql, I'm using windows 7 64 bit and Matlab 2010b.
I already installed wampserver.
Have you tried to establish MySQL connection from MATLAB using JBCC connector?
I did it successfully and put the complete workflow with the code example (requires Database Toolbox) in this question:
connection of MATLAB 7.0 and MYSQL
Haven't try on 64-bit though. Please let me know if it will fail.
UPDATE
You can also try the following submissions to File Exchange that do not require the Database toolbox:
queryMySQL
Access a MySQL database
I'm guessing you installed Matlab 64-bit as well, which does NOT come with a built-in MEX compiler (32-bit version uses lcc). You have a few options, but the easiest is to install Visual C++ Express (it's free! http://www.microsoft.com/express/Windows/) which will give you a 64-bit compatible compiler in the mex -setup listing. You'll have to double check which versions of the compiler 2010b is compatible with though.
Caveat: I tried this once and couldn't get it to work, but it was with like 2007b or something, and I didn't try that hard, I just installed 32-bit Matlab.
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.
