This lib was already built:
# find /usr/obj -name libcxxrt.so
/usr/obj/usr/src/tmp/usr/lib/libcxxrt.so
/usr/obj/usr/src/lib/libcxxrt/libcxxrt.so
But this error is only fixed after:
# cd /usr/src/lib/libcxxrt ; make install
Are you getting this error as part of buildworld, or when you build
libc++ by hand?
As part of the buildworld. I feel that it looks for the lib in the
system skipping /usr/obj.
Also, an obvious question is: does it work when you disable ccache?
Bingo. Yes, disabling ccache makes everything work.
