On Linux, this is defined in /etc/ld.conf. I'm not sure about OS-X. In this case, I think you're right, it's looking for the freetype libs, and not finding them. I'm not sure where they should be, or how to add to the path OS-X looks for them in. > I keep > running into library and path issues again and again on unix systems. I've and fewer of them than on Windows!. My solution was to build MPL against the static libs. It shouldn't be necessary for your own system, but it makes it a lot easier to distribute, and does get rid of the Path issues one you've got it built. I'll spend a few minutes messing with it now, but I don't' actually need it right now, so I won't put in much time. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

I guess I should have done that already. :-) More precisely, to maybe save some other not-entirely-Mac-clueful folks like me time, if you have installed MacPython and then ActivePython, that's $ cd /Library/Frameworks/Python.framework/Versions $ sudo cp MacPython2.4/lib/python2.4/lib-dynload/readline.so 2.4/lib/ python2.4/lib-dynload/ Works great so far.

In my case I really only use the arrow keys and tab but I suspect ipython would break if the full module was not provided. I was desperate and, lacking clues or documentation (even Google failed me), I uninstalled the ActiveState version and used the 2.4.1 installer. Frankly I really appreciated the uninstaller script and clear instructions that were part of the ActiveState distribution! Very few packages I've seen are so carefull. I'll probably try it again for a future update. Also, I and I'm sure many others would appreciate a separate download or a few README comments on how to get readline installed if it's needed. For future reference and for the benefit of other readers, I'm still unclear on how to actually get readline working. I had tried to build readline (twice, once standalone using make and once using darwinports) and it seemed to work but I don't know where to place it. This is for OS X but, in general for unix systems how can you tell where a library is supposed to be located? Is there any standard or convention? I tried a few places including /lib-dynload but ipython still complained and I got those telltale '[]^' codes when I tried to use arrow keys. I'm not done with installs. I tried to install matplotlib from source to get a current version. That went equally as well (i.e., bad), possibly for similar reasons, but that's another story. Meanwhile the old machine with rock-solid 10.3.9 and all the python 2.3 toys is quietly enjoying the show. -- Dave ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Mainly this is due to licensing issues: readline is GPL, ActivePython is free as in beer. I *do* want to make it a simple separate download to be able to plop in readline support, but haven't yet had the chance. You could either build the readline module to any Python 2.4 and plop that in. Dropping in the readline.so from the Mac Python build should work to.

[Pythonmac-SIG] readline support in ActivePython 2.4.2?
I installed the ActivePython 2.4.2 binary on a clean 10.4 system. I also installed ipython 0.6.15. ipython complains there is no readline support. I did find a readline.so file in /Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/lib-dynload/ and ipython seems to be using the 2.4.2 python version. How can I get readline to work, especially in ipython? Is there an obvious fix or should I perhaps uninstall the ActivePython version and use the 2.4.1 installer and related patches at http://undefined.org/python/ -- David ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
