gcc 4.2.2 bootstrap fails on i386-pc-solaris2.11

[Dennis Clarke]

I seem to be hitting a bad luck streak here.  First with Solaris 8 Sparc and
now with Solaris Nevada on x86.

In this case the error message is related to the file unwind-dw2.o

configure line is thus :

bash-3.2$ /export/home/dclarke/build/gcc-4.2.2/configure
--with-as=/usr/ccs/bin/as --without-gnu-ld --with-ld=/usr/ccs/bin/ld --enab
le-threads=posix --disable-nls --prefix=/export/home/dclarke/local
--with-local-prefix=/export/home/dclarke/local --enable-shared --
enable-languages=c,c++,objc,fortran --with-gmp=/export/home/dclarke/local
--with-mpfr=/export/home/dclarke/local --enable-bootstrap

Which is all well and good.

until this happens :

bash-3.2$

Did xgcc get created ?  Yes :

bash-3.2$
bash-3.2$ file /export/home/dclarke/build/gcc-4.2.2-build/./gcc/xgcc
/export/home/dclarke/build/gcc-4.2.2-build/./gcc/xgcc: ELF 32-bit LSB
executable 80386 Version 1 [FPU], dynamically linked, not stripped
bash-3.2$

But the idea of a bootstrap just went out the window it seems.

The entire filthy gory mess of output can be see at :

I am going to go backwards and simply bootstrap GCC 4.2.1 on the exact same
machine with the exact same methods. If GCC 4.2.1 is able to build to
completion then I hold the new GCC 4.2.2 a little suspect here.

I do thank, in advance, anyone curious enough to even look at all this. I
really do feel strongly that GCC should be able to bootstrap on
sparc-sun-solaris2.8 or sparc-sun-solaris2.10 or any variation thereof with
the free Sun Studio 12 compilers or with the ( $big money$ ) Sun Studio 8
compilers. Thus far I am quite able to get GCC 4.2.1 to bootstrap. I'll
verify that with a test. In the meantime I appeal to anyone that sees the
error of my ways. Please don't hesitate to provide me with suitable
correction.
