Hi Tony and Simon,
I was having this trouble today/yesterday and have been following
along on this thread. The solution I found was to add this to my
./configure:
LDFLAGS="-m64 -L/usr/lib/gcc/i686-apple-darwin9/4.2.1/x86_64 -
lgfortran"
and
F77="gfortran -arch x86_64"
You should not touch LDFLAGS and besides F77 you'll also need to set FC.
...this gets me through the "can't make mixed C/Fortran code"
errors. However, through one hoop of fire and I'm confronted by
another:
checking for iconv.h... yes
checking for iconv... no
checking for iconvlist... no
configure: error: --with-iconv=yes (default) and a suitable iconv is
not
available
...this strikes me as odd. The relevant lines from the config.log
file are:
configure:39212: gcc -std=gnu99 -o conftest -O3 -fopenmp -
mtune=native -m64 -m64 -L/usr/lib/gcc/i686-apple-darwin9/4.2.1/
x86_64 -lgfortran conftest.c -lm >&5
conftest.c: In function 'main':
conftest.c:189: warning: passing argument 1 of 'libiconvlist' from
incompatible pointer type
Undefined symbols:
"_libiconvlist", referenced from:
_main in cc2XgkAg.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
However:
swiss:R-2.9.2$ nm /usr/lib/libiconv.dylib | grep _libiconvlist
00008807 T _libiconvlist
...I'm not sure where else configure could be trying to find libiconv,
check /usr/local/lib that is the most common problem area ...
Cheers,
Simon
but
running "locate libiconv" shows versions in
/Developer/SDKs/MacOSX10.6.sdk/usr/lib/ also, which also show
_libiconvlist
when I nm them.
Any suggestions? I'm not sure how to further debug this...the
symbols are
there.
Cordially,
Adam
Hi Simon,
I think that you might have resolved my issue. I did not specify
the arch,
so I will try that and let everyone know if that works.
Cheers,

So I am trying to configure and build the latest of R-devel on one
of the
new Macbook Pro's running Snow leopard. I have installed the latest
X-Code
tools (downloaded from the Apple Site) and have gcc installed:
gcc --versioni686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple
Inc. build
5646)
So as I am trying to configure, I get this error message:
What is the exact configure command you're running? I suspect that
your
problem is a 32-bit vs 64-bit mismatch, because SL changed the gcc
default
to 64-bit whereas the gfortran default is 32-bit, so you have to
make sure
your archs match (depending on which you actually want to build) -
ideally
you should specify -arch for all compilers (as the CRAN binary
does - also
see the FAQ).

I have not seen any messages quite like this on the mailing list.
What is
pretty strange is the conftest.dSYM needs to be removed (?) for
some

but is a directory. Any ideas or suggestions on how to resolve
this?
Best,
