On Linux x86-64 (Ubuntu 6.06), the latest R sources from the
Subversion trunk fail to build with the following "recompile with
-fPIC" error:
$ ./configure --with-x=yes --prefix=$inst_dir --enable-R-shlib
--with-tcltk=/usr/lib/tcl8.4 --with-tcl-config=/usr/lib/tcl8.4/tclConfig.sh
$ make
/usr/bin/ld: ../appl/approx.o: relocation R_X86_64_32 against `a local
symbol' can not be used when making a shared object; recompile with -fPIC
../appl/approx.o: could not read symbols: Bad value
This is easy to fix by changing 4 lines in the configure script from
"-fpic" to -fPIC", as shown in the patch below.
I saw this failure on an Intel x86-64 server, running Ubuntu 6.06:
