As suggested, I tried compiling from Subversion tag 3.2.2 (r69054).
I used no command-line options to 'configure', as mentioned in my
previous email, and this is the output:

Interestintly, checking for R_ClassSymbol gives the same output as on
your working Linux system:
~/R-3.2.2$ nm -g bin/exec/R | grep R_ClassSymbol
008f8ff8 B R_ClassSymbol

I tried 'configure --enable-R-shlib', still the same error.
I then tried adding MAIN_LDFLAGS as you suggested, and the install
worked. Thanks you very much! ("make check" fails in datetime.R, but
that's something I'll follow up in a separate email.)
Should configure.ac be changed to account for this on FreeBSD's using
clang? (I should probably also try compiling with GCC, which I had to
install anyways for gfortran.)

You need to tell us exactly which commands you used: nowhere records
everything.

Here is a series of checks for that symbol (results from a working Linux
system):
auk% nm -g bin/exec/R | grep R_ClassSymbol
00962ec0 B R_ClassSymbol
auk% nm -g src/main/main.o | grep R_ClassSymbol
0008 C R_ClassSymbol

U R_ClassSymbol
~/R-3.2.2$ nm -g src/library/tools/src/gramRd.o | grep R_ClassSymbol
U R_ClassSymbol
So R_ClassSymbol is unresolved in the tools package and should be
resolved by loading into the main R executable. On Linux that is
achieved by the linker flag
-Wl,--export-dynamic
as part of MAIN_LDFLAGS in Makeconf in the top-level directory. We have
in configure.ac
freebsd*)
main_ldflags="-export-dynamic"
shlib_ldflags="-shared"
but those were from the days when FreeBSD used gcc, and it is possible
that your use of clang[*] requires -Wl,--export-dynamic . If so, add to
config.site
MAIN_LDFLAGS="-Wl,--export-dynamic"
It would also be worth trying a build with --enable-R-shlib, as that
resolves R_ClassSymbol and similar differently.
I tried 'configure --enable-R-shlib', still the same error.
I then tried adding MAIN_LDFLAGS as you suggested, and the install

It is more complicated than that, in the absence of any definitive
FreeBSD documentation. There are five possibilities:
-export-dynamic
-rdynamic
-Wl,--export-dynamic
-Wl,-export-dynamic
-Wl,-E
The first two work for GCC (and have for a long time, although only the
second is currently documented) and are accepted by compilers claiming
to be GCC-compliant (clang and icc). That clang does nothing with the
first seems a clear bug in clang (at least on some OSes (which from the
sources do include FreeBSD) it does support the second and maps it
Re: [Rd] R doesn't compile on FreeBSD 10.2
First, this there is no evidence here of a 'compilation' failure: it seems to be about installation, and more specifically about loading dynamic libs. Second, we don't have all the pertinent information such as the configure options used and the architecture (x86_64?). I am going to have to guess none as none were mentioned, but using --enable-R-shlib would be pertinent.
