Hi,
I'm not sure if this is a binutils problem or something funky in my
configure for gcc. gcc fails to link while building libgcc:

I've configured gcc with the following:
path=`pwd`
crossrc="$path/.."
host=i686-pc-gnu
target=i686-sun-solaris2.10
prefix=$crosssrc/build-install
sysroot=$crosssrc/sysroot
syslibs=$sysroot/usr/lib
sysincludes=$sysroot/usr/include
./configure -prefix=$prefix --target=$target --with-gnu-as --with-gnu-ld
--with-libs=$syslibs --with-headers=$sysincludes --enable-languages=c,c
++ --with-cpu=opteron
And I'm using the latest binutils CVS as I've been told the linker
already supports this cross-compile option.
strace'ing the build it seems to search a series of options before it
fails:
[pid 4382]
open("/export/toolchain/build-install/i686-sun-solaris2.10/bin/libc.so",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
[pid 4382]

Are these files that should of been copied over into the build directory
by binutils from the --with-libs I passed it or should they be
referencing sysroot directly.
binutils was configured with:
path=`pwd`
crossrc="$path/.."
host=i686-pc-gnu
target=i686-sun-solaris2.10
prefix=$crosssrc/build-install
sysroot=$crosssrc/sysroot
syslibs=$sysroot/usr/lib
sysincludes=$sysroot/usr/include
./configure -prefix=$prefix --target=$target --with-gnu-as --with-gnu-ld
--with-libs=$syslibs --with-headers=$sysincludes --enable-languages=c,c
++ --with-cpu=opteron
