LinuxQuestions.org - [SOLVED] Problem when trying to build a ROS package

Hello,
I'm learning how to use ROS, which is an API to develop robot applications. I'm trying to build some packages provided by ROS but I'm getting the following error:

Code:

[manu@manu rospy]$ sudo make

[sudo] password for manu: 

make: rospack: Command not found

Makefile:1: /cmake.mk: No such file or directory

make: *** No rule to make target `/cmake.mk'.  Stop.

The makefile for this package looks like this:

Code:

[manu@manu rospy]$ cat Makefile 

include $(shell rospack find mk)/cmake.mk

If I understand correctly this file, it is trying to find the path of the 'cmake.mk' file in order to execute it, but for some reason this is failing. If I execute directly in my bash shell:

Code:

[manu@manu rospy]$ rospack find mk

/home/manu/ros/ros/core/mk

the 'rospack' command works correctly, so I don't understand why it doesn't work in the Makefile.
I'm not sure of how the '$(shell ...) part of the Makefile works, I think maybe the problem could be here... I'll really appreciate any help or suggestion about this :D.
