Re: binutils 2.15 without default search path /usr/arch-linux/lib (+patch)

Hi all again,

I'm now sure it's a binutils problem with the search path for
libraries. Here my analysis of the problem and a patch against
binutils-cross-2.15-5.patch.20041130 (see Debian bug #231707).

The ld/ldmain.c:670 function set_scripts_dir() try to identify
the location of libraryies. The directory name will be determined
using the make_relative_prefix() function which create a relative
path using three informations:
 1. The path of the arch-linux-ld application (searching PATH)
 2. The BINDIR (configure option --prefix=/usr + /bin by default)
 3. The SCRIPTDIR (configure option --libdir by default {prefix}/lib)

Today folowing values are set:
 1. = /usr/bin/arch-linux-ld
 2. = /usr/bin
 3. = /usr/lib

The make_relative_prefix() function create now a relative path
between (2) and (3). This is "../lib" and applies this to the
dir's part of (1): "/usr/../lib" This directory will be now used
to determine the location of *cross* libraries.

This directory is not valid for cross-environments where libraries
are within the /usr/arch-linux/lib directory. A solution is to
set the configure --libdir=/usr/$(TARGET)/lib options. This is the
case for the patch applied to this email.
