 I had completed building tools under windows NT with binutils-2.10,gcc
 2.95.2 and gdb 5.0. and had also applyed the patch ecos-gcc-2952.pat to
 This process it's the same that i have been try to do under Linux 6.2
without sucess.
 So i moved that i had in Windows NT to correspondent folder in Linux.
 Now i'm trying to build the tools for Synthetic Linux target:
 i followed all steps in agreement with document.
 in step 3 of document, when i try configure GCC i get the follow error
message, it's the only
 message that i get:

         *** connot find config.sub.

 but inside of this folder, /src/gcc/gcc-2.95.2/ , i see config.sub,
 configure, configure.in, etc and i don't understand why it happens( the

 this is the sequence of instructions that i followed:

     mkdir -p /opt/ecos
     cd /opt/ecos
     gunzip < ecos-1.3.1.tar.gz | tar xvf -       (for the gzip archive)

 2.  cd /src
     cd -R /c/cygwin/src/* .            Note: /c/cygwin/src/* is where i
 binutils-2.10,gdb 5.0.
                                                            and gcc-2.95.2
with the patch ecos-gcc-2952.pat applyed to it.
     after that the folder /src in the Linux looks like:



     mkdir -p /tmp/build/binutils
     cd /tmp/build/binutils
     /src/binutils/binutils-2.10/configure --target=i686-pc-linux-gnu \
       --prefix=/tools \
       --exec-prefix=/tools/H-i686-pc-linux-gnu \
       -v 2>&1 | tee configure.out

     export PATH
     mkdir -p /tmp/build/gcc
     cd /tmp/build/gcc
     /src/gcc/gcc-2.95.2/configure --target=i686-pc-linux-gnu \
       --prefix=/tools \
       --exec-prefix=/tools/H-i686-pc-linux-gnu \
       --with-gnu-as --with-gnu-ld --with-newlib \
       -v 2>&1 | tee configure.out

     Note: in this point that i get tha errorr message(*** connot find
 config.sub.) .

     mkdir -p /tmp/build/gdb
     cd /tmp/build/gdb
     /src/gdb/insight-5.0/configure --target=i686-pc-linux-gnu \
       --prefix=/tools \
      --exec-prefix=/tools/H-i686-pc-linux-gnu \
       -v 2>&1 | tee configure.out


         NOTE: all other configuration was fine.
