# - Functions to analyze and list executable file prerequisites. |
| 2 |
|
|
# This module provides functions to list the .dll, .dylib or .so |
| 3 |
|
|
# files that an executable or shared library file depends on. (Its |
| 4 |
|
|
# prerequisites.) |
| 5 |
|
|
# |
| 6 |
|
|
# It uses various tools to obtain the list of required shared library files: |
| 7 |
|
|
# dumpbin (Windows) |
| 8 |
|
|
# ldd (Linux/Unix) |
| 9 |
|
|
# otool (Mac OSX) |
| 10 |
|
|
# The following functions are provided by this module: |
| 11 |
|
|
# get_prerequisites |
| 12 |
|
|
# list_prerequisites |
| 13 |
|
|
# list_prerequisites_by_glob |

# GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse> |
| 27 |
