This is as yet an unsolved problem, as LDFLAGS is the same for both C
and C++ link jobs. I think the easiest way would be to set your CXX
variable to:
CXX=cc -stdlib=libc++
Wouldn't CXX=CC -stdlib=libc++ be more appropriate, as cc is for c and CC
for c++, or have that convention gone away?
Sorry, I should have taken one more cup of coffee. :-) 'CC' is not
really recommended anymore, just use:
CXX=c++ -stdlib=libc++
My adding them to LDFLAGS comes from
https://wiki.freebsd.org/NewC++Stackwhere it says "Add -stdlib=libc++
to your compile and link flags..."
Yes, that advice is just fine, but in some cases you cannot influence
the link flags used only for C++ linking. In those cases, you will have
to trick the build system into doing so.
In most cases (but probably not all), this can be done by adding the
required flags to ${CXX}.
It
actually made a bunch of the qt4- packages build, they wouldn't without it.
I guess a wiki page tracking the failing packages would be good, but I
couldn't get the hang of creating a page there :(
This would better be done by a normal exp-run procedure, but those are
offline for the time being.
