Re: ld fails to look under /usr/$arch-linux-gnu/lib64

[Hector Oron <hector dot oron at gmail dot com>]

Hello,

  I have also been trying --with-sysroot option in binutils (2.18 and
2.19) and gcc (4.3), could you give me a hint on how to teach linker
to look for
/usr/s390-linux-gnu/lib64/libc.so, which it really is there. This
process used to work for 3.3, 3.4, 4.0, 4.1 and 4.2 without sysroot
option. But it fails on 4.3, how could i debug it?

Binutils 2.18 configure:
~~~~~~~~~~~~~~~~~
../configure --host=x86_64-linux-gnu \
               --build=x86_64-linux-gnu --target=s390-linux-gnu --prefix=/usr \
               --enable-targets=s390x-linux-gnu
--with-sysroot=/usr/s390-linux-gnu/


GCC-4.3 configure:
~~~~~~~~~~~~~~
../src/configure -v --with-pkgversion='Debian 4.3.2-1.1'
--with-bugurl='file:///usr/share/doc/gcc-4.3/README.Bugs'
--enable-languages=c,c++,objc,obj-c++ --prefix=/usr --enable-shared
--with-system-zlib  --libexecdir=/usr/lib --without-included-gettext
--enable-threads=posix --enable-nls
--with-gxx-include-dir=/usr/s390-linux-gnu/include/c++/4.3.2
--program-suffix=-4.3 --with-sysroot=/usr/s390-linux-gnu/
--enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc
--with-long-double-128 --enable-checking=release
--program-prefix=s390-linux-gnu-
--includedir=/usr/s390-linux-gnu/include --build=x86_64-linux-gnu
--host=x86_64-linux-gnu --target=s390-linux-gnu
