Supported and compatible compilers page Release 2012a

Hi,

Looking this page:

http://www.mathworks.it/support/compilers/R2012a/win64.html

I've used that Java-jdk link but its version is 1.7 and (not 1.6) and I've installed that.

So...have I to install 1.6? Can I hold both versions?

thanks

Hi Alessandro,

both questions: yes. ;-) Yes, you have to install 1.6, java 1.7 and MATLAB don't work well together (yet). And yes, you can have both of them in parallel on your machine. You should set in Windows the environment variable JAVA_HOME to point to the jdk1.6

Ok, thanks

Have I to do somewhat to set JDK 1.6 in the command windows of matlab (somewhat like the mex -setup command for Visual C++ to set C++ compiler) ? How can I check that matlab have a right JDK?

[Titus Edelhofer]

No, the Builde JA looks at the JAVA_HOME environment variable, if available, otherwise just calls javac (so the first javac.exe on the Windows Path). To be sure call in MATLAB

getenv('JAVA_HOME')

to see if the environment variable is set, otherwise you might set in MATLAB (but only for this session, or put in startup.m)

setenv('JAVA_HOME', 'C:\PathToYourJDK1.6')

setenv('JAVA_HOME', 'C:\PathToYourJDK1.6')

or:

setenv('JAVA_HOME', 'C:\PathToYourJDK with javac.exeFolder') ???

[Walter Roberson]

In the apostrophes put the path to the folder that java 1.6 is installed in.

[Titus Edelhofer]

No, the JAVA_HOME should point to the main folder (not the bin folder), e.g., "C:\Program Files\java\jdk1.6.0_23" ...

ok And the PATH and CLASSPATH variables?

I setted env. variable like...

JAVA_HOME to C:\Program Files\Java\(JDK 1.6.0.35Folder)\bin ('cause javac.exe is in there)

PATH to C:\Program Files\Java\jdk1.6.0_35\bin;C:\Program Files\OpenNI\Bin64;C:\Program Files\PrimeSense\NITE\bin64;C:\Program Files\MATLAB\R2012a\runtime\win64;C:\Program Files\MATLAB\R2012a\bin;C:\Program Files\MATLAB\MATLAB Compiler Runtime\v717\runtime\win64 (openNI and NITE are library that I need to work with MSKinect)

I have not CLASSPATH env. variable for now
