Matlab 2013b crash at start-up

If Matlab 2013b crashes at start-up with the "java.lang.NullPointerException" error, one possible solution is to temporarily change the Mac OS X version number.

For this, change the ProductVersion value from e.g., 10.10.1 to 10.90 in the file "/System/Library/CoreServices/SystemVersion.plist".

This change can be reverted once Matlab starts (recommended, since changing the OS version seems to interfere with Safari, etc.).

static linking in gcc

In order to force static linking in gcc/g++ you need to use the option
'-static'. However, unless you have installed in advance the static
versions of the glibc libraries you will receive an error such as:
> /usr/bin/ld: cannot find -lm

To install the static versions of the libraries, on RHEL variants for
instance, run:
> sudo yum install glibc-static

using external JARs in Eclipse

In order to use external JAR files in Eclipse, the most robust way if
you develop on multiple platforms is to use "Preferences > Java > Build
Path > Classpath Variables" to add a classpath variable. You can give it
any name you wish, and you must associate to it the file name of the JAR
that you want to include.

import source code in eclipse

To import existing source code in Eclipse, do the following:
1) Create a new project and give it the same name with the directory
containing your source code.
2) Uncheck "Use default location" and manually set the location to the
directory containing the source code.
Usually Eclipse automatically detects your source code, and you can
simply click "Finish" to finalize project creation.
