22
23 Change the install name of all wxWidgets libraries in the directory DIR (or
24 current directory if libdir option is not specified) to correspond to the given
25 install_path (defaults to the libraries directory if not specified).
26
27 If prefix option is given, its value is prefixed to the tool names used. E.g.
28 to use this script when cross-building, use "--prefix=powerpc-apple-darwin8-".
29
30 -n, --dry-run Don't really do anything, just print the commands
31 -q, --quiet Don't display any non error messages
32 -v, --verbose Just show the commands being executed, don't run them
33 -h, --help Show this help screen and exit
34
35 Examples:
36 * do "$name --libdir=MyApp.app/Contents/Frameworks @executable_path/../Frameworks"
37 when distributing wxWidgets shared libraries with application MyApp
38 * run "$name" without parameters in the directory containing wxWidgets libraries
39 to use them without installing
