# This Python script is used within the OS X release process, to ensure
|
|
# that the standalone OS X ZIP files which we make are actually
|
|
# standalone, and not implicitly dependent on Homebrew installs for
|
|
# external libraries which we use.
|
|
#
|
|
# This implicit dependencies seem to show up only where we have
|
|
# external dependencies which are dependent on each other, and the
|
|
# path from one to another is an absolute path to "/usr/local/opt",
|
|
# the Homebrew install location. External dependencies which only
|
|
# depend on system libraries are fine. Our main applications seem
|
|
# to be fine.
|
|
#
|
|
# An example of a dependency which requires this fix-up at the time
|
|
# of writing is the following dependency edge:
|
|
#
|
|
# libjsonrpccpp-client.0.dylib
|
|
# -> /usr/local/opt/jsoncpp/lib/libjsoncpp.0.dylib
|
|
#
|
|
# See https://blogs.oracle.com/dipol/entry/dynamic_libraries_rpath_and_mac
|
|
# for a little overview of "install_name_tool" and "otool".
