I am using lldb, to avoid going through some signing rigmarole with gdb. When I start it up it complains about not being able to find a dynamic library in /usr/local/lib, which is correct, as it's not there. On investigation, DYLD_LIBRARY_PATH is correctly set, but is ignored. As far as I can tell, this is by design: the System Integrity Protection feature of macOS 10.11 and later disables DYLD_LIBRARY_PATH. This means that dynamic libraries can't be loaded in-place using current libtool (I am using 2.4.6). At the moment, my workaround will be to install the library in /usr/local/lib, as I don't want to disable SIP on the Mac I'm borrowing to test a Darwin build of my code! I guess it won't be long before such security mechanisms surface in popular GNU/Linux distros=E2=80=A6 I presume that the measures that XCode uses to get around this could be used in GNU libtool (though I confess I don't know what they are, and right now don't plan to look, as I'm not a regular Darwin user, just someone trying to make code compile on this popular platform, sigh). --=20 http://rrt.sc3d.org --001a114a8a5c454f0c0547572d71 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div class=3D"gmail_default" style=3D"font-size:small">[Ap= ologies if this is not news; I searched the mailing list archive, but didn&= #39;t find anything about this.]</div><div class=3D"gmail_default" style=3D= "font-size:small"><br></div><div class=3D"gmail_default" style=3D"font-size= :small">I have just been trying to debug some libtoolized code on macOS 10.= 12 (Sierra).</div><div class=3D"gmail_default" style=3D"font-size:small"><b= r></div><div class=3D"gmail_default" style=3D"font-size:small">I am using l= ldb, to avoid going through some signing rigmarole with gdb.</div><div clas= s=3D"gmail_default" style=3D"font-size:small"><br></div><div class=3D"gmail= _default" style=3D"font-size:small">When I start it up it complains about n= ot being able to find a dynamic library in /usr/local/lib, which is correct= , as it's not there.
