Install MotOrBac on Gentoo

Here is a little howto for installing MotOrBac - a tool for managing security policies based on orbac - on a gentoo linux (2007.0). Please, note that I'm not part of the MotOrBac project, any comment should be addressed to the contacts specified on the web site.

The version MotOrBac I worked with is labelled "first stable release" (2007/03/23) on Sourceforge.

Install the required dependencies

As far as I know, only swi-prolog and a jdk are needed. I found nowhere which versions should be installed. So here is what I installed:

Java jdk, blackdown, 1.4.2.03-r15
```
emerge -a dev-java/blackdown-jdk
		
```
swi-prolog 5.6.37 with java support (to have jpl.jar) - I have the following use flags for swi-prolog if it can help: X berkdb -debug -doc -elibc_FreeBSD -gmp java -minimal -odbc readline ssl -static -tetex -threads zlib
```
USE="java" emerge -a dev-lang/swi-prolog
		
```

Launch MotOrBac

First, go to MotOrBAC/bin

Without environment variables

Execute:

LD_LIBRARY_PATH=/usr/lib/pl-5.6.37/lib/x86 java -classpath .:/usr/lib/pl-5.6.37/lib/jpl.jar:JLexCup.jar motorbac.MotOrBAC

(replace pl-5.6.37 if the version of swi-prolog is different)

With environment variables

set the variables

in sh-compliant shells:

export LD_LIBRARY_PATH=/usr/lib/pl-5.6.37/lib/x86
export CLASSPATH=.:/usr/lib/pl-5.6.37/lib/jpl.jar:JLexCup.jar

in C shells:

setenv LD_LIBRARY_PATH=/usr/lib/pl-5.6.37/lib/x86
setenv CLASSPATH=.:/usr/lib/pl-5.6.37/lib/jpl.jar:JLexCup.jar

then launch MotOrBac:
```
java motorbac.MotOrBAC
		
```

you can now remove the environment variables:

in sh-compliant shells:

unset LD_LIBRARY_PATH
unset CLASSPATH

in C shells:

unsetenv LD_LIBRARY_PATH
unsetenv CLASSPATH

Using MotOrBac

When creating a new projet, add a the extention ".pl" at the end of the name, the soft doesn't add it by itself even if the list box of the JFileSelect filters on .pl files
