Hi Rob and Edward, I bear good tidings of great joy!
I recently received a new MacBook Pro and did a fresh upgrade to Mac OS 10.7 (Lion). I then used the opportunity to test out installation procedures of various software on a clean system. My main finding is that the excellent Homebrew (mxcl.github.com/homebrew/) makes things much easier these days. Why Homebrew? It does not try to replace every single bit of functionality on your Mac with their own version, like Macports or fink. It reuses the existing libraries as far as possible. No need to reinstall Python, for example (one of my pet gripes when people try to install new software on their Macs, and the source of much confusion and pain). It installs to /usr/local, the standard place to find third-party libraries and headers, instead of the obscure /opt or /sw. It's simple to use and to extend. I last installed Leo on Mac OS 10.4 (Tiger) back in the Tk days, and wondered what it looked like in Qt. All the horror stories of PyQT on Mac discouraged me from trying this before, so I was keen to see if Homebrew helps. Here is my installation write-up: - Make sure you have Xcode installed (test it by confirming that "gcc" runs in the Terminal) - In preparation for homebrew, the best option in my opinion is to delete /usr/local via:: sudo rm -rf /usr/local and install any software in it via homebrew instead. If this step fills you with dread and you do not want to lose your beloved third-party software, the second-best option is to make sure you have write permission for the directory via:: sudo chown -R <your user name>:admin /usr/local If you don't know your username, run "whoami". :-) This is useful because homebrew actually discourages you from installing third-party software as the superuser (the usual Mac apps in /Applications are also installed as the normal user, for that matter). - Install Homebrew (http://mxcl.github.com/homebrew/) by running the following command in the Terminal:: /usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)" - Run "brew update" to get the latest formulas - Now install PyQT (yes, that's it!):: brew install pyqt - Run "brew doctor" and check any further suggestions to improve your system. - Add the following lines to your ~/.bash_profile (or ~/.profile on Leopard):: export PATH=/usr/local/bin:$PATH # This is for SIP (and PyQT) as suggested by Homebrew export PYTHONPATH=/usr/local/lib/python:$PYTHONPATH - Open a new Terminal tab / window so that the above settings take effect, and install Leo. I downloaded the Leo-4.9-final-a.zip, unzipped it, and ran "python launchLeo.py" inside the Leo directory. We should consider adding a Homebrew formula for Leo. This will simplify the process even further, to simply "brew install leo". I started on this, but wasn't sure where to put the various Leo files in the system hierarchy. The Debian package can give some clues here, but I haven't looked at it yet. Now I just have to start using Leo after all these years of checking it out... :-) Regards, Ludwig -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
