Can your ros_workspace folder be located on an NTFS file system?

I'm using ros electric and a wubi install of ubuntu 11.10.

I've added a new hard drive that I want both windows and linux to access, and I'd like to move my ros_workspace folder to the new hard drive. Unfortunately when I run my nodes from the new environment I get:

$ rosrun loader_testing boomPosCnt

[rosrun] Couldn't find executable named boomPosCnt below /media/may2013/ros_workspace/loader_testing [rosrun] Found the following, but they're either not files, [rosrun] or not executable: [rosrun] /media/may2013/ros_workspace/loader_testing/bin/boomPosCnt

When I switch the environment back to the old workspace in my home folder (ext4 file system) the nodes run fine. Thanks!

I think the problem lies in the fact that NTFS does not follow Unix file system permission conventions (read/write/executable), in particular the concept of executable permissions.

When you try to run the node "boomPosCnt", it does not have execute permissions.

There is a workaround in the following thread which involves mounting the NTFS partition in a way that gives execute permissions...it may help with your problem:
