More permission-denied errors

[linas]

Per last-nights email:

after a clean install, and creating a a password for user ubuntu, the install works but the build breaks with this error message:

The problem is that the directories /opt/hansonrobotics, and everything in /opt is owned by root, after the /tmp/hrtool -i step.

[linas]

To be clear: in a normal linux system, the /opt directories are always owned by root, not by users, and so CppMT should not be trying to write log files into that location ... this is a bug in the CppMT code.

If the hrtool places directories in /opt owned by the user, instead of root, that's an hrtool bug...

[tesYolan]

I think the https://github.com/hansonrobotics/HEAD/blob/master/scripts/hrtool#L446 should have handled it. It's not particular a problem of the CppMT. I think for whatever reason that step is being skipped when it's invoked.

[linas]

I'm re-installing from scratch, to see if it happens again. Its possible that this is due to bad procedure -- I had previously run /tmp/hrtool -i as root.

[linas]

The re-install from scratch seems to avoid this problem.

Okay. I close it.
