''This is a slightly edited version of the'' [[http://bugs.debian.org/237265|bug report #237265]]. ''Thanks to'' RyanMurray ''for providing this information''.

The older versions of {{{libtool}}} fail to correctly support shared libraries for the Debian {{{mips}}} and {{{mipsel}}} architectures. Debian versions 1.5-2 and 1.4.2-7 and higher correctly support them. You need to update all of the {{{libtool}}} related files by running the following on your source tree:
{{{
 autoreconf --force
}}}
You may need to use the {{{--install}}} option as well.  You can also try the individual commands needed yourself:
{{{
 libtoolize --force --copy
 aclocal
 autoheader
 automake -a
 autoconf
}}}
{{{autoheader}}} may not be needed, and you may need to use versioned binaries ({{{autoconf2.13}}}, {{{automake-1.{4,6,7}}}}, {{{aclocal-1.{4,6,7}}}}, etc)

The correct {{{configure}}} script will have output that looks like this:
{{{
 # This must be Linux ELF.
 linux-gnu*)
   case $host_cpu in
   alpha* || hppa* || i*86 || mips || mipsel || powerpc* || sparc* || ia64* || arm* || m68k)
     lt_cv_deplibs_check_method=pass_all ;;
   *)
}}}
It is important that {{{mips}}} and {{{mipsel}}} (or {{{mips*}}}), {{{arm}}}, and {{{m68k}}} are listed in the configure script here, or seeing the following comment:
{{{
 # linux always uses pass_all now, this code is the old way (tm)
}}}
Older versions of {{{libtool}}} used a file_magic check for the pattern
{{{
 ELF [0-9][0-9]*-bit ["LM"]SB (shared object||dynamic lib )
}}}

The output of {{{file(1)}}} on a shared library on {{{mips}}} does not match this regular expression, however. Earlier versions of file had been modified to match this regular expression, but the latest version uses the same output as upstream once again.  The file check often causes problems, and results on a build-dep on file that you might not otherwise be aware of. The new method doesn't need {{{file(1)}}} at all, and is far less fragile, so it is best to upgrade the {{{configure}}} script with proper {{{mips}}} support.

A line like
{{{
 .''libtool: line 1: s%^.*''%%: No such file or directory
}}}
indicates that the definition for SED is missing -- this happens when part of {{{libtool}}} has been updated, but not the rest of the {{{auto*}}} stuff that is also needed.
