[Scons-users] OSX Library link names include undesired prefix

[Rob Boehne]

$ORIGIN is not a Mac OS X construct.  It¹s recognized by linkers on many
*NIX platforms, but not OS X.
To my knowledge, this isn¹t an SCons thing either, so what I use is
something like this:

    env.Append(SHLINKFLAGS='-Xlinker -rpath -Xlinker @loader_path/.¹)

which is roughly equivalent to this under Linux:

    env.Append(SHLINKFLAGS=['-Wl,-rpath,\\$$ORIGIN'])

Hope this helps.
