[vtkusers] Need Help Compiling VTK on OS X With Python Wrappers and a Local Python Installation

Fri Jan 29 08:12:58 EST 2010

Thanks for the info Darren. I have given up the attempt to build and install using the approach that I was attempting. I generally use Linux platforms for development, but I also have a Mac and I was attempting to build the same infrastructure on the Mac as I have on the Linux machines.

I did not know that macports software could be installed in an alternate directory. I will look into it. However, I want to use my local Python installation, and that is where I have had difficulty.

You might try using macports without a root installation path.  The default path is /opt/local/, but that can be changed.  There may be some ports that contain instructions that require root access (perhaps apache, mysql, postgresql, etc. have system init scripts that require root access).

Seems to me that your swimming a little too hard against the tide, esp. with .so libs on OSX/Darwin.  How about you lighten your work load by asking your sys admin to install all your libraries?  How about running your own system with root access (try Ubuntu)?

Take care,
Darren
