Preflight

A simple set of Python scripts to automate building static libraries for iOS. This script uses 'flightplans' as configuration items for building a library.

Usage

python preflight.py build <flightplan name>

Where <flightplan name> is the filename of any python script in the flightplans sub-directory without the '.py' extension. For example:

python preflight.py build libspatialite

Output currently goes to ~/iOS_libs and is not yet configurable. The library does not create a fat binary for you but it is easy to do:

lipo -create <path to armv7 lib> <path to armv7s lib> <path to i386 lib> -output myFatBinary.a

Obviously, if you build for other architectures than those above, you can add them as well.

Creating a Flightplan

Copy one of the existing ones and use it as a template. The flightplan.py script should also be used as reference since it contains the super class for all flightplans. Each flightplan is just a python script so it should be easily configurable.

More flightplans welcome!

Misc

The build directory is preflight/Flightbag. This directory is conveniently ignored by .gitignore.

TODO

• The flightplans are currently configured for what I need at my place of work (ForeFlight). Work needs to be done to allow custom configurations with ease.
• Create fat binaries automatically
• Configurable output location
• Package lib + necessary header files

preflight's Issues

Cannot build gdal 1.10.1 on Maverick Xcode 5.0.2

Hi,
I'm working hard on compiling gdal for iOS and I ran into your python scripts (wonderful work btw) but I'm stuck with a weird issue.
let me explain the situation:
1- gdal 1.10.0 won't be compiled because of some known issues with OSX/iOS on gdal side discussed here and here
2- After changing gdal.py to reflect the need to download 1.10.1 instead of 1.10.0, when I run

python preflight.py build gdal

certain errors come up that when I investigate, I can see that the linker is trying to link standard libraries from OSX SDK (in /usr/include/sys) instead of iOS SDK (/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/sys)! this leads to errors like _Unsupported Architecture_ in cdef.h and all.

P.S.: proj4 gets compiled for all architectures and is present in ~/iOS_libs output directory, gdal compiles for i386 & x86_64 only.
P.P.S: I have limited my Archs to armv7 for the sake of speed. I had to remove arm64 because it wouldn't pass for proj4.
same error goes for 1.10.0,1.10.1, 1.9.2

How can I overcome this issue?
