This is actually cross-posted on stackoverflow to ask as a general python question. Here I ask in ROSy way.

On QNX realtime OS, I'm trying to install catkin_pkg from source, and seeing the following error upon running pip.

# pip install -U catkin_pkg 
Downloading/unpacking catkin-pkg
  Running setup.py egg_info for package catkin-pkg

OSError: [Errno 89] Function not implemented
Storing complete log in /root/.pip/pip.log

The first time I ran this pip command when the depended components (such as argparse, docutils, python-dateutil and six) were not installed, the same error happened too, but not during installation of catkin_pkg but while checking these required components are installed. Now that I've installed them one by one, it seems to be happening at while installing catkin_pkg itself.

On python's console, os.fork(), which I assumed is the root cause, behaves differently. Thus I'm not even sure if the error occurs at os.fork() or somewhere different.

# python
Python 2.7.4 (default, Jun 21 2013, 22:33:48) 
[GCC 4.4.2] on qnx6
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.fork()
18804790
>>> 0
sem_wait: Invalid argument

How can I avoid this error? Thank you!

Using QNX 6.5.0 SDP SP1, pip version is 1.3 (its source on github)


Update) When trying to install bloom via pip the same error happened.

I somehow figured it out. Running pip WITHOUT -U option gets catkin_pkg installed (install log is at the bottom for the reference).

...But why...? Help message of pip's doesn't seem to make sense to me:

$ pip install --help
:
Install Options:
:
  -U, --upgrade   Upgrade all packages to the newest available version. This process is recursive irregardless of whether a dependency is already satisfied.

Log of installation by pip:

$ pip install catkin_pkg    
Downloading/unpacking catkin-pkg
  Running setup.py egg_info for package catkin-pkg

Requirement already satisfied (use --upgrade to upgrade): argparse in /usr/pkg/lib/python2.7/site-packages (from catkin-pkg)
