I have been trying to get EigenD to build on my Mac (OSC 10.6.8) without any luck. I just get a big list of errors when I "simply type make". I have the latest version of Xcode, however am pretty much a noob on OSX, so possibly I am missing something obvious. Do I need some additional software to be installed for SCONS? Any tips would be much appreciated.

Another question I have is that since I only have a Pico, will this even work for me?

barnone,

Here are the start of the lines of errors, from the 1st one :

After looking at the Building on Lion thread, it would appear I am having the same issue, as I am currently running g++ 4.2.1. Considering I am not running Lion, which solution should I try to apply?

Also my question about the Pico remains - am I wasting my time building EigenD with only a Pico to work with?

Thanks for your help barnone! I will give it a try tomorrow, getting too late tonight.

I decided to have another go at getting this environment to build. I uninstalled xcode4, installed xcode3 (moved it to /Developer-old) and reinstalled xcode4.

Changed the select_tools.py and darwin_tools.py to refer to /Developer-old but I still can't build due to a reference to /usr/pi

Now, I realize that such a folder exists on the machine where I actually RUN the software but that's not a development machine so it doesn't have xcode on it.

Is it possible to just modify the following line

unix_tools.PiUnixEnvironment.__init__(self,platform,'usr/pi','Library/Eigenlabs',python='/usr/pi/bin/python')

to point to my existing python installation?

There has been some weirdness with later versions of Python being installed without upgrading other libraries that EigenD uses. The recommended way is to really use the runtime tools that are installed in /usr/pi.

That's a matter of perspective. I'd like to avoid impacting my development environment, on which I depend to make a living!

Eigenharp is a hobby. I'd rather make the Eigen stuff fit into my environment rather than having to change my environment (with potential risks to other projects since I don't know how the EigenD stuff impacts other stuff) to suit Eigen.

Yes you can just copy over /usr/pi from your other machine.
