[kencu (Ken)]

well, in this port, the configure script does the right thing

checking for wcsdup... no
checking for strndup... no

and does it's own replacements, as it should. So the snowleopardfixes library is not needed (and appears to be detrimental), because it installs for me without modification

$ port -v installed ftgl
The following ports are currently installed:
  ftgl @2.1.3-rc5_0 (active) platform='darwin 10' archs='x86_64' date='2017-07-03T15:35:31-0700'

Peter,

All you should need to do now is to add

PortGroup snowleopard_fixes 1.0

to the top of the Portfile

[kencu (Ken)]

Oh, but not in this port -- it does the right thing already.

[And - of interest - this build fails with the portgroup added without an included header to define the function. Yet on other ports, including the header messes up the build due to unexpected #defines pulled in. So we can not have the snowleopard_fixes library included by default on all ports until / unless I get that header business totally figured out, as Peter demonstrates here.

If I was really smart, I'd find a way to make the snowleopardfixes thing part of clang directly.]

Replying to kencu:

Yes, confirmed! It builds with the original Portfile.

macOS 10.6 builders report success for ftgl. Can this ticket be closed, or is there still an issue?
