Hello,
Sorry if this is the wrong place to post or if this has been addressed
elsewhere. I am running R 2.10.1 under OS X 10.5 (Leopard). After
upgrading R from 2.10 to 2.10.1, I found that no source package would
install, with errors like:
gcc-4.2 -arch i386 -std=gnu99 -I/Library/Frameworks/
R.framework...
make: gcc-4.2: Command not found
make: *** [bisse-eqs.o] Error 127
(similar errors for any package containing C code that I tried). The
Xcode that U have does not include gcc 4.2, so it is surprising to see
it being selected. I think I have the most recent Xcode available for
Leopard; in any case, the only Xcode I seem to be able to get from
apple needs OSX 10.6.
I have worked around this problem by creating a ~/.R/Makevars file
containing
CC = gcc-4.0 -arch i386 -std=gnu99
CFLAGS = -g -O2
CXX = g++-4.0 -arch i386
CXXCPP = g++-4.0 -arch i386 -E
CXXFLAGS = -g -O2
DYLIB_LD = gcc-4.0 -arch i386 -std=gnu99
F77 = gfortran-4.0 -arch i386
FC = gfortran-4.0 -arch i386
FCFLAGS = -g -O2
MAIN_LD = gcc-4.0 -arch i386 -std=gnu99
OBJC = gcc-4.0 -arch i386
OBJCFLAGS = -g -O2
OBJCXX = g++-4.0 -arch i386
SHLIB_CXXLD = g++-4.0 -arch i386
SHLIB_FCLD = gfortran-4.0 -arch i386
SHLIB_LD = gcc-4.0 -arch i386 -std=gnu99
after which compilation succeeds (I had to both switch the version
numbers from 4.2 to 4.0 compared with R's Makevars and drop the -
mtune=core flag).
I have a couple of questions
(1) Will anything terrible happen as a consequence of doing this?
(2) Does this situation mean that package compilation is no longer
supported on leopard?
Thanks,
Rich
