 ====== Mac Development Environment ======
+For packaging of latest version, see [[proj:macinstallers]]
+This page is relevant to building new template (containing binaries etc).
+NOTE - need a new version to handle 10.7 (Lion) upwards. Explanation:
+  Hi Grant,
+  I remembered the reason that for OS X support sometimes being limited to 10.7.
+  It's because of C++11. The standard library that goes with this, libc++, is only
+  supported as far back as 10.7. If you want to support earlier versions then all
+  of the C++ bits need to be built for and linked against the old stdc++ library.
+  Cheers
+  Glenn

 I thought I could get away with --with-drivers=PNG but it failed but =FILES dropped it enough (about 17MB) and worked.

 Success!
+If delegates.xml can't be found, the error message might be something like:
+  convert: UnableToOpenConfigureFile `delegates`.xml' @warning/configure.c/GetConfigureOptions/706.
+If the command used to handle something doesn't work the error message from imagemagick is not very useful. It will be something like:

+===== Practical Packaging =====
+To simplify things, maybe do the dependable.py strategy on pdftk so ALL files are in one folder. One less thing to have to handle.
+That would mean we have stable Frameworks (convert, gs, delegates.xml, colors.xml, wkhtmltopdf etc etc) and Resources folders (has sofastatistics.icns and all the pyinstaller bits and pieces) and the only thing that changes is the MacOS folder.
+So modify spec file to copy across those two folders into app once made, and copy contents from sofa.main into MacOS and we have a package ready to go.
