We require binutils 2.11 or newer. Previous binutils releases
had a number of problems with DWARF2 debugging information, not
the least of which is incorrect linking of shared libraries.
This section contains general configuration information for all
alpha-based platforms using ELF (in particular, ignore this section for
OSF and tru64). In addition to reading this section, please read all
other sections that match your target.
We require binutils 2.11.1 (as of yet unreleased), binutils with
binutils-2_11-branch tag after May 31, 2001 (as taken below), or newer.
Previous binutils releases had a number of problems with DWARF2
debugging information, not the least of which is incorrect linking of
shared libraries.
Until binutils 2.11.1 is released, these sample commands may be useful:
@smallexample
mkdir binutils-2.11.X; cd binutils-2.11.X
cvs -d :pserver:anoncvs@@anoncvs.cygnus.com:/cvs/src \
co -rbinutils-2_11-branch -P binutils
mkdir obj; cd obj
../src/configure --prefix=@emph{an-absolute-path}
make all check install
@end smallexample
When configuring gcc, provide explicit @option{--with-gnu-as}
@option{--with-as=}@emph{an-absolute-path/bin/as} and
@option{--with-gnu-ld} @option{--with-ld=}@emph{an-absolute-path/bin/ld}
options to point into the prefix used above.

The version of binutils installed in /usr/bin is known to work unless
otherwise specified in any per-architecture notes. However, binutils
2.11 is known to improve overall testsuite results.
For FreeBSD 1, FreeBSD 2 or any mutant a.out versions of FreeBSD 3: All
configuration support and files as shipped with gcc 2.95 are still in
place. FreeBSD 2.2.7 has been known to bootstrap completely; however,
it is unknown which version of binutils was used (it is assumed that it
was the system copy in /usr/bin) and C++ EH failures were noted.
For FreeBSD using the ELF file format: DWARF2 debugging is now the
default for all CPU architectures. It had been the default on
FreeBSD/alpha since its inception. You may use @option{-gstabs} instead
of @option{-g}, if you really want the old debugging format. There are
no known issues with mixing object files and libraries with different
debugging formats. Otherwise, this release of gcc should now match more
of the configuration used in the stock FreeBSD configuration of gcc. In
particular, @option{--enable-threads} is now configured by default.
However, as a general user, do not attempt to replace the system
compiler with this release. Known to bootstrap and check with good
results on FreeBSD 3.0, 3.4, 4.0, 4.2, 4.3 and 5-CURRENT.
At this time, @option{--enable-threads} is not compatible with
@option{--enable-libgcj} on FreeBSD.
