Ok, the simplescalar docs are telling:
"SimpleScalar/Alpha binaries must be built on Digitial Alpha OSF Unix (or
with a suitable cross compiler). Any Alpha OSF Unix compiler should
work, however, the binaries must be statically linked. To statically
link a binary, add the "-static" flag to the link line of GNU GCC, or add
"-non_shared" to the link line of the DEC compilers."
So let's hope you will understand what "producing binaries (or
'executables')"
means: compiling, assembling and then linking against the startups
('crt*.o) and
base C libraries ('libc', 'libm' etc.). The two first steps in
"compiling" can be
made possible by producing the GNU binutils and the GNU C compiler. BUT
those "target libraries", here the "Alpha OSF Unix" ones must most probably
be taken from this target system... The 'simpletools-2v0.tgz' package
(with
gcc-2.6.3) however seemed to include glibc-1.09, so maybe this could replace
those original Alpha OSF target libraries....
I tried install gcc 3.1 and binutils 2.12 but binutils fails because of this
error:
"coff-alpha.c:1455: error: invalid lvalue in assignment"
would you please tell me which version of binutils and gcc I should install to
be able to generate alpha binaries suitable for simplescalar and if they have
some bugs for installation is there any document or patch to remove the bugs?
I tried the binutils-2.14.90.0.8 and the gcc-3.3.6 sources for the
'alpha-dec-osf4' target.
The binutils build succeeded nicely but the GCC build stopped with :

Maybe because I hadn't any OSF4 headers available.... Or there really is
some problem in the GNU binutils/GCC support for 'alpha-dec-osf*'.
If your situation is quite the same, no Alpha/OSF stuff being available,
then
even if building both binutils and only-GCC ("make all-gcc") would succeed,
there is still that question about the target C library, where on earth
to get it :(
