[LLVMdev] cannot find -lgcc_s

I am trying to build llvm-gcc4.2-2.6. 

My configure options are 

 $ /local/tools/lin32/llvm-gcc4.2-2.6/bin/llvm-gcc -v
Using built-in specs.
Target: i686-linux
Configured with: ../llvm-gcc4.2-2.6.source/configure
--prefix=/local/tools/lin32/llvm-gcc4.2-2.6 --disable-nls --enable-shared
--enable-threads=posix --enable-languages=c,c++ --with-gnu-as --with-gnu-ld
--target=i686-linux
--with-as=/local/tools/lin32/binutils-2.17.50.0.15/bin/i686-linux-as
--with-ld=/local/tools/lin32/binutils-2.17.50.0.15/bin/i686-linux-ld
--enable-llvm=/local/tools/src/llvm-gcc4.2-2.6/build-i686-linux-llvm/objdirllvm
--program-prefix=llvm- --enable-libffi=no --enable-__cxa_atexit
--with-sysroot=/local/tools/lin32/glibc-2.2.5-44 --disable-tls
--enable-clocale=gnu
Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5649) (LLVM build)

I do a make bootstrap and make install after configure. 

But when I try to run this gcc I get

 $ /local/tools/lin32/llvm-gcc4.2-2.6/bin/i686-linux-llvm-gcc a.c
/local/tools/lin32/binutils-2.17.50.0.15/bin/i686-linux-ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

libgcc_s.so*  is presnet under /local/tools/lin32/llvm-gcc4.2-2.6/lib

Any ideas what is going wrong here? print-search-dirs gives the following which
obviuosly does not include libgcc_s.so* path

$ /local/tools/lin32/llvm-gcc4.2-2.6/bin/i686-linux-llvm-gcc -print-search-dirs

If I try to build it without --with-sysroot everything works fine. But not with
--with-sysroot. Any suggestions?

does the same thing happen if you configure, build and install mainline gcc 4.2
rather than llvm-gcc?

Ciao,

Thanks for the reply Duncan. --with-sysroot is messing up the path. gnu
gcc-4.2.1 works fine with --with-sysroot. So I guess this is problem is specific
to llvm-gcc.
