Please Help.. CrossGCC for arm-uclinux Using Gatliff's Method and Wirespeed Toolchain - So Close...

["Brian" <bwang at mltc dot com dot tw>]

Hello,

I'm very new to the GNU toolchain.  I really need some help...
I'm trying to build a cross GNU toolchain for arm-uclinux on RedHat 7.0.

The toolchain set that I'm using is from the WireSpeed ftp site:
ftp://ftp.wirespeed.com/uClinux
=======================================
arm_uclinux_binutils_10_31_2000.tar.gz
arm_uclinux_gcc_10_31_2000.tar.gz
uC-glibc-2.1.3-10112000.tar.gz
=======================================

I had a tough time going through the toolchain building process until
I found Bill Gatliff's FAQ site at:
http://crossgcc.billgatliff.com/
which I found makes more sense than getting pre-built target headers
from others.

There's no option for arm-uclinux in Gatliff's script so I followed
it even though I can only guess the meaning from the bash script.
(Linux newbie...)  I was able to get through the core gcc and the
glibc process without any error.  When I got back to complete the
full gcc build, there was a [needed-list] make error.
I tried to look at the makefile but just could not comprehend.
The error message is as follows:
===================================
[snip..]
Adding multilib support to Makefile in ../../../../../arm-uclinux-
gcc/libiberty
with_multisubdir=pic/soft
make[1]: Entering directory `/root/uclinux_wirespeed/build-gcc/arm-
uclinux/libiberty'
rm -f needed-list; touch needed-list; \

  for g in  ; do \
<= something missing here?
    case "$g" in \
      *$f*) echo $g >> needed-list ;; \
    esac; \
  done; \
done
/bin/sh: -c: line 1: syntax error near unexpected token `;'
/bin/sh: -c: line 1: `rm -f needed-list; touch needed-list;  for f in

echo $g >> needed-list ;;  esac;  done;  done'
make[1]: *** [needed-list] Error 2
========================================================

I looked at the output file.  The needed-list make process seems to
be run more than once but failed at last.  The needed-list target
section of the makefile is:
==================================
needed-list: Makefile
 rm -f needed-list; touch needed-list; \
 for f in $(NEEDED); do \
   for g in $(LIBOBJS) $(EXTRA_OFILES); do \                  <= causing
problem????
     case "$$g" in \
       *$$f*) echo $$g >> needed-list ;; \
     esac; \
   done; \
 done
==================================
The $(LIBOBJS) symbol disappeared at the erroneous attempt seen from
the output.  "LIBOBJS =  mkstemps.o" is defined at the top of the
makefile.

But at the previous attempt, the LIBOBJS symbol seems to be present
as seen from the beginning of the output.
====================================
make[1]: Entering directory `/root/uclinux_wirespeed/build-
gcc/libiberty'
rm -f needed-list; touch needed-list; \
for f in atexit calloc memchr memcmp memcpy memmove memset rename
strchr strerror strrchr strstr strtol strtoul tmpnam vfprintf vprintf
vfork waitpid bcmp bcopy bzero; do \
  for g in mkstemps.o ; do \
<= mkstemps.o is here!
    case "$g" in \
      *$f*) echo $g >> needed-list ;; \
    esac; \
  done; \
done
[snip..]
====================================

I don't know what went wrong...  Any hint?
I don't know if this is a configuration error or not.  Here is my
configuration of the full-gcc:
../arm-uclinux-gcc/configure --prefix="/opt/arm-uclinux-tools" --
target=arm-uclinux --enable-languages=c,c++ --with-local-
prefix=/opt/arm-uclinux-tools/arm-uclinux 2>&1 | tee configure_gcc.log

I really appreciate Gatliff's effort of making the FAQ.  Maybe after
I'm through with this, he can add the arm-uclinux option in the one-
step build script and benefit others interested in arm-uclinux. : )

Any help is appreciated.

Thanks. :)


Brian
