Problems cross-compiling GCC 2.95.1 host=sparc-sun-solaris2.7 target=sparcv9-sun-solaris2.7

["Kevin Neel" <kevinsn at earthlink dot net>]

When creating a cross compiler GCC 2.95.1 (host=sparc-sun-solaris2.7
target=sparcv9-sun-solaris2.7) using a native 2.95.1, I get the following
messages:

(1)
../../gcc-2.95.1/gcc/config/sparc/gmon-sol2.c:184: `PATH_MAX' undeclared
(first use in this function)

(2)
checking whether the C compiler

neel/gcc/inst-cross/sparcv9-sun-solaris2.7/bin/ -g -O2 ) works... no
configure: error: installation or configuration problem: C compiler cannot
create executables.

(3)
I get a number of warnings indicating that function declarations aren't in
effect.  These are generally in building the library.  E.g.:

----------------------------------------------------------------------------
---------------------

My methodology for building the compiler is this:

1. Build a bootstrap native compiler 2.95.1 (sparc-sun-solaris2.7) --
successful (an old gcc was the base compiler)
2. Build a cross compiler sparc-sun-solaris2.7 => sparcv9-sun-solaris2.7,
using the Sun ld and as -- warnings
3. [Not there yet] Use #2 to bootstrap a sparcv9 compiler


In step 2, I'm using the following definitions:
set target=sparcv9-sun-solaris2.7
set prefix=/home/kneel/gcc/inst-cross

set path = (~/gcc/bin /opt/SUNWspro/bin /usr/ccs/bin /usr/ccs/lib /usr/bin
\
            /etc /usr/ucb /usr/dt/bin /usr/games /usr/local/x11/bin
\
            /usr/openwin/bin /home/kneel/bin ~/gcc/inst-v8/bin            )

alias config  ../gcc-2.95.1/configure --host=sparc-sun-solaris2.7 \
              --target=$target --prefix=$prefix \
              -v --enable-languages=c++

alias build  make MAKE="make -j 2" -j 2


... where ~/gcc/inst-v8/bin is the installation of the native 2.95.1
compiler and ~/gcc/bin includes
nazgul%  ls -l ~/gcc/bin
total 0
lrwxrwxrwx   1 kneel    geneva         25 Aug 18 17:25 make ->
/usr/progressive/bin/make
lrwxrwxrwx   1 kneel    geneva         19 Aug 19 14:41 perl ->
/usr/local/bin/perl
lrwxrwxrwx   1 kneel    geneva         15 Aug 19 12:37
sparcv9-sun-solaris2.7-ar -> /usr/ccs/bin/ar
lrwxrwxrwx   1 kneel    geneva         15 Aug 19 12:41
sparcv9-sun-solaris2.7-nm -> /usr/ccs/bin/nm
lrwxrwxrwx   1 kneel    geneva         19 Aug 19 14:02
sparcv9-sun-solaris2.7-ranlib -> /usr/ccs/bin/ranlib


In my install directory for the cross compiler, I have:
nazgul%  ls -l ~/gcc/inst-cross/sparcv9-sun-solaris2.7/
total 16
lrwxrwxrwx   1 kneel    geneva         12 Nov  5 23:34 include ->
/usr/include
drwxrwxr-x   9 kneel    geneva      16384 Nov  5 23:30 sys-include
and I have copied all files from /usr/include/sys into the above sys-include
directory.


My host is:
nazgul%  uname -a
SunOS nazgul 5.7 Generic_106541-07 sun4u sparc SUNW,Ultra-Enterprise


I'm attaching the .i file for libgcc2.c and the entire log of the build in
step 2.


Any ideas?  Am I configuring this wrongly?  Has anyone tried this
combination?

 Thanks,
  Kevin
