It seems your compiler doesn't support ObjC. You should get a working

mileage may vary even if you get Apple driver and a more complete
compiler. More comments inline below.

Hi R-fellows,
I have some fatal errors compiling the R source files with
gcc-4.7.1 on my Mountain Lion and I wonder if this is only on my
Mac or if it does happen on other Macs too (I use the gcc-4.7 as I
want to compile some C++ code that uses OpenMP 3.1).
Here is the way I did it:
1. (gcc-4.7) Install gcc-4.7 on my Mac following
http://solarianprogrammer.com/2012/07/21/compiling-gcc-4-7-1-mac-osx-lion/
(This runs quite well)
2. (Configure) Getting the R-2.15.1.tar.gz from
http://cran.r-project.org,
I used on the shell:
tar -zxvf R-2.15.1.tar.gz cd R-2.15.1* mkdir build && cd build
Further, for the R configure to work it needs the XCode Command
Line Tools
Now as the gcc-4.7 is not the default compiler on my Mac and R
needs X11 the configure line is a little nasty but works without
errors (see also
http://stat.ethz.ch/R-manual/R-patched/doc/manual/R-admin.html#Installing-R-under-_0028Mac_0029-OS-X):
../configure CC="gcc-4.7 -arch x86_64" CXX="g++-4.7 -arch x86_64"
F77="gfortran-4.7 -arch x86_64" FC="gfortran-4.7 -arch x86_64"
OBJC="gcc-4.7 -arch x86_64"
-x-libraries=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib
-x-includes=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/include
--with-lapack --with-blas='framework vecLib'
(The usual installation given on
http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html, i.e.:
../configure CC="gcc-4.7 -arch $arch" CXX="g++-4.7 -arch $arch"
F77="gfortran-4.7 -arch $arch" FC="gfortran-4.7 -arch $arch"
OBJC="gcc-4.7 -arch $arch" --x-includes=/usr/X11/include
--x-libraries=/usr/X11/lib --with-blas='framework vecLib'
--with-lapack
having defined arch=x86_64
does not work on my machine, as it seems that XCode installs the
Command Line Tools with the X11SDK in
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11.
Again, possibly a problem with your compiler, a supported compiler
doesn't need that hack. But also 10.8 doesn't come with X11 so I
assume you installed XQuartz accordingly ...
Compiling with this line usually gives:
configure: error: --with-x=yes (default) and X11 headers/libs are
not available)
Note that the instructions are for Apple compilers and those
compatible (e.g. FSF builds with Apple driver driver which adds extra
flags and parses others). For any other compilers, you're on your own
and the flags may vary.
3. (Make) Doing now the make gives me huge amount of fatal errors
with no clue where it comes from and no google documentations so
far. All make output can be seen here:
http://pastebin.com/3baL8php
I have really no clue where these come from,
They some from including AppKit, apparently your compiler doesn't
even work with system frameworks. Even if you fix this instance there
is Quartz as well. There are a lot of broken compiler builds around,
so I'm not surprised. If you have to avoid all system services, you
can try to build without aqua, but I don't think that has been tested
recently on OS X ...
Would yesterday do?
but maybe somebody of you guys has encountered either these errors
as well or has found another way to compile R with gcc-4.7?
Best Regards
Simon
