I guess we need a Tcl wrapper around dlopen_preflight to fix this? Any other suggestions?

comment:3 Changed 13 days ago by jmroot (Joshua Root)

Well, in this particular case the libcxx dependency makes this check redundant, right?

No, please don't do that. That is not the right solution. Toby landed that temporarily while we wait for API for a proper solution.

I suggest we just do this check on darwin 11 and earlier.

comment:6 Changed 9 days ago by kencu (Ken)

that was what I was thinking too, but just wanted to see where this was going. I'll take care of that, and in libcxx too.
