Working on -current as of about March 7.
I'm building some software that uses the standard FreeBSD Makefile
includes
but it's failing on its library linking (the linking of a library
which is part of the application)
with the following error
[...]

*** Error code 1
Stop.
the same error happens with gcc as the compiler..
so the obvious question is "why does clang want to link with libgcc?"
and another question is:
why can't it find it? At least for that there is an answer:
julian@vps1:ls -la /usr/lib/libgcc_s.so
lrwxr-xr-x 1 root wheel 46 Apr 30 08:13 /usr/lib/libgcc_s.so ->
/usr/obj/usr/src-current/tmp/lib/libgcc_s.so.1
but I've deleted /usr/obj.
Does anyone know WHY the "make installworld" back in March just made
symlinks for this (and a whole bunch more) libraries?
and has it been fixed?
As for the libgcc question,
the Makefile appears as shown below. If there is anything I should
have done differently I'd like to know.
