Hello,Dave,and others,

Thanks to you,
as I applied patch that you taught me,I cleared next error.
> checking for shared libgcc... configure: error: Link tests are not

I exulted and expected to succeed,but lastly(I hope)
there happened next error.

checking for C compiler default output file name... configure: error: C 
compiler
 cannot create executables
See `config.log' for more details.
make[1]: *** [configure-target-libssp] Error 1
make[1]: Leaving directory `/tmp/build/build_gcc'
make: *** [all] Error 2
make: Leaving directory `/tmp/build/build_gcc'

I searched among many config.logs and found that
\tmp\build\build_gcc\sh-elf\m2a\libssp\config.log
contained above error message.

It says,

See `config.log' for more details.

I also noticed other config.logs relating to  each libssp directories
contained error messages like next.

'me'

I do not know why it happened,and what I should do,
would you please help me ?

I append the same config.log and build logs "configgcc.txt","makegcc.txt" in 
tar.bz2 format.

Below are my shell scripts.
===============================================
[setup.sh]
export TARGET=sh-elf
export PREFIX=/usr/local/sh-elf
export CFLAGS="-O2"
export CXXFLAGS="-O2"
export CFLAGS_FOR_TARGET="-Os"
export CXXFLAGS_FOR_TARGET="Os"
===============================================
[appendpath.sh]
PATH=$PATH:/usr/local/sh-elf/bin
===============================================
I separated building shell script.
[buildgcc-1.sh]
/usr/local/sh-elf/gcc-4.1.1/configure --target=$TARGET --prefix=$PREFIX --enable-languages=c,c++ 
 --with-gnu-as --with-gnu-ld --with-newlib --with-ggxx-include-dir=/usr/local/sh-elf/sh-elf/include 
 --with-ecos -v  2>&1 | tee configgcc.txt

[buildgcc-2.sh]
make clean
make -w all install 2>&1 | tee makegcc.txt
===============================================
I am very much obliged to your help.
Thank you in advance.

Masahiro Ariga
