Matlab install - Java permission denied

Question

Matlab version 2012. I know there are many threads about this, suggesting to chmod +x the following files (if you are in installation directory):

sys/java/jre/glnx86/jre/bin/java
sys/java/jre/glnxa64/jre/bin/java

I also chmodded the install file in root of installation directory. However, after running sudo ./install I still get:

Preparing installation files ...
Installing ...
./install: 1: eval: /tmp/mathworks_4880/sys/java/jre/glnxa64/jre/bin/java: Permission denied
Finished

How is this possible? :)

Answer 1

Even at your 64bit system, the installation might as well work out coz i have just successfully installed Matlab2012a in mine... here's what i did.. :

1.in the /matlab-install-files/sys/java/jre/glnx86/jre/bin/java ,i did

 sudo chmod +x ./java

2.within the installation directory:

 sudo chmod +x ./install

3.finally, install by:

 ./install 

or

 sudo ./install

Answer 2

Installing Matlab (which is 32-bit) on 64-bit Ubuntu causes this problem. You can try this command and proceed like normal again.

ln -s YOURMATLABFOLDER/sys/java/jre/glnx86 YOURMATLABFOLDER/sys/java/jre/glnxa64

Answer 3

I did the following on my 64-bit Ubuntu and it worked.

chmod +x <MATLAB_DIRECTORY>/java/jre/glnx86/jre/bin/java

<MATLAB_DIRECTORY> is the directory where you have all the MATLAB installation files in.

Then, in the install script (<MATLAB_DIRECTORY>/install), change line 441 from

JRE_LOC=

to

JRE_LOC="<MATLAB_DIRECTORY>/java/jre/glnx86/jre/"

And then run ./install in the <MATLAB_DIRECTORY>

Answer 4

I've found the answer, no matter how weird it is. The problem was 64bit OS. When I tried with 32bit, Matlab installation worked and every other app I had previously trouble installing. So now I stick to 32bit.
