blocks|key|2215758|text|我已经找到了答案，不管这有多奇怪。问题是64位操作系统。当我尝试使用32位时，Matlab的安装工作正常，而我以前安装的每一个应用程序都有问题。所以现在我坚持32位。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

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.

blocks|key|4512116|text|即使在您的64位系统中，安装工作也可能会进行，因为我刚刚成功地在我的系统中安装了Matlab2012a。我就是这么做的..。：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4512117|1.在/matlab-install-files/sys/java/jre/glnx86/jre/bin/java中，我做了|4512118|+sudo+chmod+%2Bx+./java|code-block|syntax|javascript|4512119|2.在安装目录中：|4512120|+sudo+chmod+%2Bx+./install|4512121|3.最后，通过以下方式安装：|4512122|+./install+|4512123|或|4512124|+sudo+./install|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|V|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|W|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|X|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|Y|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|Z|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|10|8|@]|9|@]|A|$]]|$1|O|3|P|5|F|7|11|8|@]|9|@]|A|$G|H]]|$1|Q|3|R|5|6|7|12|8|@]|9|@]|A|$]]|$1|S|3|T|5|F|7|13|8|@]|9|@]|A|$G|H]]]|U|$]]

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

<pre><code> sudo chmod +x ./java
</code></pre>

2.within the installation directory:

<pre><code> sudo chmod +x ./install
</code></pre>

3.finally, install by:

<pre><code> ./install 
</code></pre>

or

<pre><code> sudo ./install
</code></pre>

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

<pre><code>ln -s YOURMATLABFOLDER/sys/java/jre/glnx86 YOURMATLABFOLDER/sys/java/jre/glnxa64

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

<pre><code>chmod +x &lt;MATLAB_DIRECTORY&gt;/sys/java/jre/glnx86/jre/bin/java
</code></pre>

<code>&lt;MATLAB_DIRECTORY&gt;</code> is the directory where you have all the MATLAB installation files in.

Then, in the install script (<code>&lt;MATLAB_DIRECTORY&gt;/install</code>), change line 441 from

<pre><code>JRE_LOC=
</code></pre>

to

<pre><code>JRE_LOC="&lt;MATLAB_DIRECTORY&gt;/sys/java/jre/glnx86/jre/"
</code></pre>

And then run ./install in the <code>&lt;MATLAB_DIRECTORY&gt;</code>

In many cases, the file system on which the install disk is mounted, is such that the file's permission cannot be changed to +x. In such cases, open the <code>install</code> script, go to somewhere around line which does <code>echo Installing....</code> and <code>eval $java_cmd</code>. Just put a <code>read</code> between these two lines. Then, in another tab, go to <code>/tmp/mathworks_&lt;some-4-digit-random-number&gt;/sys/java/jre/glnxa64/jre/bin/</code> and do <code>chmod +x java</code>. Then in the previous tab, press enter.

I assumed the appropriate symbolic link is, instead, something like 

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

If you want to link the missing x86 JRE folder with the existant x64 of your install location.

blocks|key|2216126|text|还有一个名为install_unix的文件，您必须对它应用chmod+%2Bx技巧。不记得它在哪个文件夹中，但它会立即清除，因为它不是在子文件夹中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2216127|另外，当您选择要安装哪些组件时，许可证管理器是自动不被选中的。请不要选它--它只会引起麻烦。|2216128|确保安装文件夹是正确的，因为这不能真正改变否则。出于管理原因，我不得不移动它，但最终放弃了尝试，只是重新安装(尽管这可能会花费我的大学一些钱)。|2216129|另一件可能有帮助的事情是选择安装脚本(类似于此)，这样就可以运行一个文件来真正启动MATLAB。您可以不使用此选项，但是每次启动时，您都必须直接访问一个关键的程序文件，这可能有点危险。不要担心安装这些脚本的文件夹，因为您可以复制它们，无论它们在哪里，运行时它们都会链接到MATLAB根文件夹。|2216130|安装完毕后，通过右键单击目录栏并选择preferences，可能有助于更改启动目录。启动目录应该是您希望保存您自己创建的与MATLAB相关的文件的地方，比如脚本和函数&可能是运行它们/其他数据的结果。将MATLAB根文件夹用于这类事情可能真的很危险。|2216131|没有必要更改install_info文件，因为安装选项是使用对话框接口确定的。|2216132|您可能希望安装桌面快捷方式来访问MATLAB而不打开终端。为此，终端需要在bash模式下运行。我安装了快捷键，但我想我不明白怎么回事，所以我让你自己解决/查一下。|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|Q|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|R|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|S|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|T|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|U|8|@]|9|@]|A|$]]]|N|$]]

There's also a file called install_unix which you have to apply the chmod +x trick to. Can't remember which folder it's in, but it'll be clear straight away as it's not in a subfolder.

Also, when you're selecting which components to install, there's a reason the licence manager is automatically not selected. Please leave it unselected - it'll just cause trouble.

Make sure the installation folder is correct, as this can't really be changed otherwise. I had to move it for administrative reasons, but eventually gave up trying and just reinstalled (though that might have cost my University some money).

Another thing that might help is to take the option to install scripts (something like that) so that there's a file you run to actually start MATLAB. You can make do without this option, but then every time you start you'll have to directly access a critical program file, which might be a little bit dangerous. Don't worry about the folder where these scripts are installed, as you can make copies and wherever they are, when run they'll link to the MATLAB root folder.

Once you've installed, it might help to change the startup directory by right clicking in the directory bar and selecting preferences. The startup directory should be where you want to keep MATLAB-related files you made yourself, like scripts and functions &amp; maybe results from running them/other data. It might be really dangerous to use the MATLAB root folder for this sort of thing.

It's not necessary to alter the install_info file as the installation options are determined using a dialog box interface.

You might like to install a desktop shortcut to access MATLAB without opening a terminal. For this, the terminal needs to be operated in bash mode. I got the shortcut installed, but I don't think I understand how so I'll leave you to work that out/look it up.

blocks|key|4512471|text|解压ISO文件，而不是挂载，确保下列文件具有读写权限后，使其可执行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4512472|install|ordered-list-item|offset|length|style|CODE|4512473|/home/amb/I/sys/java/jre/glnxa64/jre/bin+(里面的所有文件)|4512474|bin/glnxa64/install_unix|4512475|然后执行./install|entityMap^0|0|0|7|0|0|14|0|0|O|0|4|9^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|Q|8|@$E|R|F|S|G|H]]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@$E|U|F|V|G|H]]|9|@]|A|$]]|$1|K|3|L|5|D|7|W|8|@$E|X|F|Y|G|H]]|9|@]|A|$]]|$1|M|3|N|5|6|7|Z|8|@$E|10|F|11|G|H]]|9|@]|A|$]]]|O|$]]

Extract the ISO files instead of Mount and then make the following files executable after ensuring they've got the read-write permission:

<ol>
<li><code>install</code></li>
<li><code>/home/amb/I/sys/java/jre/glnxa64/jre/bin</code> (all files inside it)</li>
<li><code>bin/glnxa64/install_unix</code></li>
</ol>

then execute <code>./install</code>

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



<pre class="lang-none prettyprint-override"><code>sys/java/jre/glnx86/jre/bin/java
sys/java/jre/glnxa64/jre/bin/java
</code></pre>

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

<pre class="lang-none prettyprint-override"><code>Preparing installation files ...
Installing ...
./install: 1: eval: /tmp/mathworks_4880/sys/java/jre/glnxa64/jre/bin/java: Permission denied
Finished
</code></pre>

How is this possible? :)

Matlab install - Java permission denied
