71 <h3 class="appendixsec">E.5 Using 32-Bit Dictionaries on a 64-Bit System</h3>
73 <p>Due to an oversight, Aspell compiled dictionaries not only depend on
74 the endian order, they also depend on the the size of the
75 <code>size_t</code> type, which is generally different on 32 and
76 64-bit systems. The <code>size_t</code> type is used in the hash function
77 of the compiled dictionaries. To force the hash function to use a
78 32-bit integer instead, use the <samp>--enable-32-bit-hash-fun</samp>
79 configure option. This option will allow you to use dictionaries
80 compiled on a 32-bit machine on a 64-bit one as long as the endian
81 order is the same. Of course, dictionaries compiled on a 64-bit
82 machine without this option enabled will no longer be usable. If
83 Aspell detects that an incompatible hash function is used, it will fail
86 <p>Error: The file “<var>some-file</var>” is not in the proper format. Incompatible hash function.
