 ====== 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

 Cannot use standard installers as are all 64-bit (will get Bad CPU error message). So ignore the binary-releases page. Homebrew works when osx 10.6.8 and xcode 3.2.2. (unlike 10.6.0 and 3.2) so ...

 At one point there seemed to be a permissions problem with /usr/lib again so needed to sudo chown -R `whoami` /usr/local again and then brew link various libs: libtiff jbig2dec little-cms2 ghostscript. Might not be required but try it if a problem.
+===== Ghostscript (gs) =====
+Don't bother with a brew install. Just download latest source, extract, cd into folder with configure inside and:
+  ./configure --disable-dynamic --with-drivers=FILES
+I thought I could get away with --with-drivers=PNG but it failed but =FILES dropped it enough (about 17MB) and worked.
+--disable-dynamic bakes in a whole lot so gs doesn't try to find it outside e.g. gs_init.ps. No need to have a parallel share/ghostscript/...gs_init.ps
+===== convert and gs =====
+  - Don't compile ghostscript with gslib on board
+  - Do export MAGICK_CONFIGURE_PATH='/...' whatever path you put delegates.xml in
+  - Do put colors.xml in same folder (now you've got all the essential configuration files I need)
+  - Ensure PATH is set to start with the folder gs is in. Removes need to hardwire in the path to gs all over the place.
+  export PATH=<folder_gs_etc_are_in>:${PATH}
+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:
+  convert: NoImagesDefined `/Users/g/Desktop/test.png' @error/convert.c/ConvertImageCommand/3212.

+===== 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.
