| # Builds a Exiv2 framework for the iPhone and the iPhone Simulator. | |
| # Creates a set of universal libraries that can be used on an iPhone and in the | |
| # iPhone simulator. Then creates a pseudo-framework to make using libexiv2 in Xcode | |
| # less painful. | |
| # | |
| # To configure the script, define: | |
| # IPHONE_SDKVERSION: iPhone SDK version (e.g. 8.1) | |
| # | |
| # Then go get the source tar.bz of the libexiv2 you want to build, shove it in the | |
| # same directory as this script, and run "./libexiv2.sh". Grab a cuppa. And voila. | |
