first off I'd like to think you and Kai and the others who have been
helping me with this problem.  IT is very much appreciated

OK, I dowloaded and successfully built the current edition binutils.
"make install" put them in /usr/arm-angstrom-linux-gnueabi/bin and
/usr/arm-angstrom-linux-gnueabi/binutils.

I used this as the configure command line for the binutils.

./configure
 --build=i686-linux-gnu
 --host=i686-linux-gnu
 --target=arm-angstrom-linux-gnueabi
 --prefix=/usr/arm-angstrom-linux-gnueabi-binutils
 --exec-prefix=/usr/arm-angstrom-linux-gnueabi-bin/utils
 --with-build-sysroot=/tmp/arm
 --program-prefix=arm-angstrom-linux-gnueabi-binutils
 --program-suffix=-2.23.2
--disable-werror

(I broke them out into individual lines to make it easier to read.

I am now trying to use Kai's configure command line

./configure
 --build=i686-linux-gnu
 --host=i686-linux-gnu
 --target=arm-angstrom-linux-gnueabi
 --prefix=/usr/arm-angstrom-linux-gnueabi
 --exec-prefix=/usr/arm-angstrom-linux-gnueabi
 --with-build-sysroot=/tmp/arm
 --libdir=/usr/arm-angstrom-linux-gnueabi/lib
 --libexecdir=/usr/arm-angstrom-linux-gnueabi/lib

 --enable-c99
 --enable-long-long
 --enable-symvers=gnu
 --enable-libstdcxx-pch
 --enable-__cxa_atexit
 --enable-shared
 --enable-threads=posix
 --enable-target-optspace
 --enable-lto
 --enable-libssp
 --enable-cheaders=c_global
 --enable-version-specific-runtime-libs
 --with-linker-hash-style=gnu
 --with-ppl=no
 --with-cloog=no
 --with-gxx-include-dir=/opt/cross/include/c++/4.8.0
 --disable-silent-rules
 --disable-dependency-tracking
 --disable-nls
 --disable-libgomp
 --disable-libmudflap
 --disable-multilib
 --program-prefix=arm-angstrom-linux-gnueabi-
 --program-suffix=-4.8

Slightly modified to:   (I tried it unchanged to begin with)

./configure
--build=i686-linux-gnu
--host=i686-linux-gnu
--target=arm-angstrom-linux-gnueabi
--prefix=/usr/arm-angstrom-linux-gnueabi
--exec-prefix=/usr/arm-angstrom-linux-gnueabi
--with-build-sysroot=/tmp/arm
--libdir=/usr/arm-angstrom-linux-gnueabi/lib
--libexecdir=/usr/arm-angstrom-linux-gnueabi/lib
--enable-languages=c,c++
--enable-c99
--enable-long-long
--enable-symvers=gnu
--enable-libstdcxx-pch
--enable-__cxa_atexit
--enable-shared
--enable-threads=posix
--enable-target-optspace
--enable-lto
--enable-libssp
--enable-cheaders=c_global
--enable-version-specific-runtime-libs
--with-linker-hash-style=gnu
--with-ppl=no
--with-cloog=no
--disable-silent-rules
--disable-dependency-tracking
--disable-nls
--disable-libgomp
--disable-libmudflap
--disable-multilib
--disable-werror

It successfully completes the first pass and runs for awhile on the
second pass (with xgcc) where it fails with

There is a pthread.h in

./fixincludes/tests/base/pthread.h
./fixincludes/tests/base/sys/pthread.h

but neither of those are in the search path for xgcc.  I tried setting
$PATHS but that variable isn't used in configure when it generates that
makefile.

I'm pretty much at my wits' end right now.  I can't figure out why Kai
got his to work but using the same configure command I can't.


This is what my currently installed and working compiler says to the -v
command

I've tried that too, modified to my install location but with no joy.
