Well, after the installation was complete, the "ecosconfig" util was kept
under <install path>/ecos-3.0/tools/bin

I'm trying to use the command line for configuring a target:

~/ecos/ecos-3.0/ecos-work$ ../tools/bin/ecosconfig new atmel
ecos.db: error
    couldn't read file
"/home/mandeep/ecos/ecos-3.0/tools/bin/ecos.db": no such file or
Invalid package database.

How do I create the ecos.db file?

Do I need to do make install....isn't the ecosconfig util supposed be
under /usr/local/bin (default) ?
