Can't run a example by Doop - Framework for Java Pointer Analysis

Question

I am trying to using Doop framework. I am following this link: https://bitbucket.org/yanniss/doop

I downloaded the code and compiled it successfully. but when I am trying to Running Doop by the following command

$ DOOP_HOME>./bin/doop -a context-insensitive -j ./lib/asm-debug-all-4.1.jar

in my case, it is :

./doop -a context-insensitive -j ../lib/asm-debug-all-5.0.3.jar

But, unfortunately, I got an error.

vuquangvinh@vuquangvinh-VPCEA24FM:~/tutorial/DoopFramework/code/doop/bin$ ./doop -a context-insensitive -j ../lib/asm-debug-all-5.0.3.jar 
:: loading settings :: url = jar:file:/home/vuquangvinh/tutorial/DoopFramework/code/doop/lib/ivy-2.3.0.jar!/org/apache/ivy/core/settings/ivysettings.xml
The EXTERNALS directory is invalid: null

I have no idea what is happening. I have tried, but this framework seems to be not popular. Anyone can help me!

Many thanks!

As stated in the documentation the tool expects several environment variables DOOP_HOME , DOOP_OUT , DOOP_HOME and DOOP_EXTERNALS to be set and it simply complains that DOOP_EXTERNALS is not set.

Instead of setting the environment variable you can also pass the externals directory via command line option --externals <the directory> .
