Can't build arm-elf cross compiler

[hiroyuki matsumoto]

Hello,

I constructed the cross compiler for arm-elf on Cygwin,
referring to "Getting Started with GNU" by William Gatliff.
But, I have not succeeded in construction yet.
Then, I have some questions.Please answer.

<Environment>
 Cygwin         : 1.3.2
 GCC            : gcc-core-3.0.1
                  gcc-g++-3.0.1
 BINUTILS       : binutils-2.11.2
 NEWLIB         : newlib-1.9.0
 HOST           : Windows98 machine  (i586-pc-cygwin)
 TARGET         : ARM7(arm-elf)


<Construction>
STEP1
  PATH was set in the file of "Cygwin.bat" as follows.

 ...
  SET PATH=/tools/arm-elf/bin:$PATH
  SET PATH=/bin
 ...

  and, after "Cygwin" had been started, typing later.

  $ export PATH=$PATH:/tools/arm-elf/bin


STEP2
  $ ../binutils-2.10.1/configure --target=arm-elf \
                                 --prefix=/tools 2>&1 | tee configure.log
  $ make all install 2>&1 | tee make.log

 These succeeded.


STEP3
  $ cd /src/gcc-3.0.1
  $ ln -s /src/newlib-1.9.0/newlib

 Is this link necessary?
 Is "libgloss" also necessary?
 Or, is neither necessary?


STEP4
  Before executing "gcc-configure", I added the definition to
  "/src/gcc-3.0.1/gcc/config/arm elf.h" as follows.
  Because not call "main()".

 Add:
  #define HAS_INIT_SECTION

  to beginning of elf.h file.


  Is this correct?
  Or,do not change it?


STEP5
  $ ../gcc-3.0.1/configure --target=arm-elf --prefix=/tools \
                           --without-headers --with-newlib 2>&1 | tee
configure.log

 This succeeded.


STEP6
  Before executing "gcc-make", I changed "tmp/build/gcc/gcc makefile" as
follows.

 change from:
  # Additional target-dependent options for compiling libgcc2.a.
    TARGET_LIBGCC2_CFLAGS =

 to:
  # Additional target-dependent options for compiling libgcc2.a.
    TARGET_LIBGCC2_CFLAGS = -Dinhibit_libc


 Is this correct?
 Or,do not change it?


STEP7
  $ make all-gcc install-gcc 2>&1 | tee make.log

 The following errors occur at "gcc-make".
 "arm-elf-ar:not found"


 Then, the error was compulsorily excluded by setting PATH
 of the directory with "arm-elf-ar".

  $ export PATH=$PATH:/tools/bin


 The error occurs in my PC if "gcc-make" is executed at once after
"gcc-configure".
 Therefore, my PC has been reactivated before "gcc-make" is done.
 For this, is not "arm-elf-ar" found?
 And, how should deal?


STEP8
 $ ../newlib-1.9.0/configure --target=arm-elf --prefix=/tools    \
                             2>&1 | tee configure.log
 $ make all install 2>&1 | tee make.log

 These succeeded.


STEP9
 $ ../gcc-3.0.1/configure --target=arm-elf --prefix=/tools \
                           2>&1 | tee configure.log
 $ make all install 2>&1 | tee make.log

 It is the same as the result of "STEP7".

When compiling by the compiler made according to procedure above,
the following errors occur.

Please answer.
