Re: FreeBSD 9.1 missing libcxxrt - is it needed for objc2?

[Frank Rehwinkel]

This thread is about the same problem with FreeBSD 9.1 back in March.

http://lists.gnu.org/archive/html/gnustep-dev/2013-03/msg00127.html

The solution seems to be to build libcxxrt.

But how?  When I try to follow this instruction

I've put MK_LIBCPLUSPLUS = yes in /etc/make.conf now.

and cd to /usr/src/lib/libcxxrt/ but then make fails with

address@hidden:/usr/src/lib/libcxxrt # make

"/usr/share/mk/bsd.own.mk", line 478: MK_LIBCPLUSPLUS can't be set by a user.

So I just don't know how to get this library built.  Not as simple as getting a port compiled I guess.

libsupc++.a does have symbols in it.

nm -g reports no symbols on libsupc++.so.1.

Oh it just hit me - maybe you want libsupc++.a instead of .so, which (may) ask for libc++ to build.

I used to simply force linking libobjc2 against libc++ but that tend to make app load a little slower and consume some more memory (and then defeat this performance penalty by enforcing link-time optimization in Base and GUI).

I've checked the libsupc++ libraries are the same on the host as in the jail.  Same sizes, same symbolic links.

Hmm, this should work.  The C++ runtime symbols are missing from this library?
