I now reinstalled XCode and build the gcc-4.7 new, explicitly telling to build a objc compiler. Furthermore I installed the XQuartz package and can now use the symbolic link /usr/X11. 

1. (Configure) Running the command: 

../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 libVec' --with-lapack

or

../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="objc-4.7 -arch $arch" --x-includes=/usr/X11/include/ --x-libraries=/usr/X11/lib/ --with-blas='-framework libVec' --with-lapack

Gives no errors nor warnings in the configure step.

2. (Make) Doing a make with:

make -j 8

gives me still errors with aqua: http://pastebin.com/n3g6zYfS

If I try to build without aqua I do the following:

1. (Configure) I configure with: 

../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="objc-4.7 -arch $arch" --x-includes=/usr/X11/include/ --x-libraries=/usr/X11/lib/ --with-blas='-framework libVec' --with-lapack --without-aqua

All runs fins - no errors nor warnings. 

2. (Make) Running the command::

make -j 8

gives again errors with X11 (but quite different): http://pastebin.com/HXqLgH4b

Is there still a possible way to build R from sources with gcc-4.7?


Best regards
