older <CODE>automake</CODE> or <CODE>libtool</CODE> installation.
<H3><A NAME="FOOT19" HREF="autobook_85.html#DOCF19">(19)</A></H3>
<P>Position Independent
Code -- suitable for shared libraries which might be loaded to different
addresses when linked by the runtime loader.
<H3><A NAME="FOOT20" HREF="autobook_90.html#DOCF20">(20)</A></H3>
<P>The functionality
of <TT>`ltconfig'</TT> is slated for migration into <TT>`libtool.m4'</TT> for
a future release of <CODE>libtool</CODE>, whereupon this file will no
longer be necessary.
<H3><A NAME="FOOT21" HREF="autobook_90.html#DOCF21">(21)</A></H3>
<P><A HREF="ftp://ftp.gnu.org/gnu/config/">ftp://ftp.gnu.org/gnu/config/</A>
<H3><A NAME="FOOT22" HREF="autobook_94.html#DOCF22">(22)</A></H3>
<P>Actually the suffix will be  whatever is appropriate
for the target host: such as <SAMP>`.obj'</SAMP> on Windows for example.
<H3><A NAME="FOOT23" HREF="autobook_95.html#DOCF23">(23)</A></H3>
<P>For example, when I come to using the <SAMP>`make dist'</SAMP> rule.
<H3><A NAME="FOOT24" HREF="autobook_95.html#DOCF24">(24)</A></H3>
<P>The GNU standard is distributed from
<A HREF="http://www.gnu.org/prep/standards.html">http://www.gnu.org/prep/standards.html</A>.
<H3><A NAME="FOOT25" HREF="autobook_96.html#DOCF25">(25)</A></H3>
<P>This is for
Autoconf version 2.13.  Autoconf version 2.50 recommends
<CODE>AC_CONFIG_COMMANDS</CODE>.
<H3><A NAME="FOOT26" HREF="autobook_98.html#DOCF26">(26)</A></H3>
<P>This is a sort
of callback function which will be called by the <CODE>make</CODE> rules
generated by Automake.
<H3><A NAME="FOOT27" HREF="autobook_100.html#DOCF27">(27)</A></H3>
<P>By default, GNU <CODE>tar</CODE> can create non-portable archives in
certain (rare) situations.  To be safe, Automake arranges to use the
<SAMP>`-o'</SAMP> compatibility flag when GNU <CODE>tar</CODE> is used.
<H3><A NAME="FOOT28" HREF="autobook_101.html#DOCF28">(28)</A></H3>
<P>Probably numbered 1.5.
<H3><A NAME="FOOT29" HREF="autobook_106.html#DOCF29">(29)</A></H3>
<P>There has been some debate in the Autoconf
community about extending Autoconf to allow new directories to be set on
the <CODE>configure</CODE> command line.  Currently the consensus seems to be
that there are too many arguments to <CODE>configure</CODE> already.
<H3><A NAME="FOOT30" HREF="autobook_107.html#DOCF30">(30)</A></H3>
<P>The most common way being to simply
set <CODE>prefix</CODE>.
<H3><A NAME="FOOT31" HREF="autobook_107.html#DOCF31">(31)</A></H3>
<P>This example assumes the use of GNU tar
when extracting; this is standard on Linux but does not come with
Solaris.
<H3><A NAME="FOOT32" HREF="autobook_114.html#DOCF32">(32)</A></H3>
<P>These names come from <CITE>Gulliver's Travels</CITE>.

<H3><A NAME="FOOT35" HREF="autobook_132.html#DOCF35">(35)</A></H3>
<P>Windows does permit a program to use a
forward slash to separate directories when calling routines such as
<SAMP>`fopen'</SAMP>.  However, Windows users do not expect to type forward
slashes when they enter file names, and they do not expect to see
forward slashes when a file name is printed.
<H3><A NAME="FOOT36" HREF="autobook_156.html#DOCF36">(36)</A></H3>

<P>Not essential but will be slower
without this option, see <A HREF="autobook_71.html#SEC71">10.2.1 Position Independent Code</A>.
<H3><A NAME="FOOT39" HREF="autobook_160.html#DOCF39">(39)</A></H3>
<P>HP-UX being the most notable
exception.
<H3><A NAME="FOOT40" HREF="autobook_167.html#DOCF40">(40)</A></H3>
<P>As I
always like to say, `from BeOS to Windows!'.  And yes, I do think that
it is a better catchphrase than `from AIX to Xenix'!
<H3><A NAME="FOOT41" HREF="autobook_167.html#DOCF41">(41)</A></H3>
<P>Use <SAMP>`AM_PROG_LIBTOOL'</SAMP>

into your distribution.
<H3><A NAME="FOOT46" HREF="autobook_185.html#DOCF46">(46)</A></H3>
<P>This is very different to the way
errors are managed when writing a custom loader for libltdl. Compare
this section with <A HREF="autobook_177.html#SEC177">Loader Errors</A>.
<H3><A NAME="FOOT47" HREF="autobook_188.html#DOCF47">(47)</A></H3>

and both Ksh and the Bourne shell on Solaris.
<H3><A NAME="FOOT53" HREF="autobook_220.html#DOCF53">(53)</A></H3>

<H3><A NAME="FOOT65" HREF="autobook_251.html#DOCF65">(65)</A></H3>
<P>In general, a stub function will
satisfy the linker's requirements to resolve an undefined symbol at
link time, but has no functionality of its own.  In this context, the
stubs do have some boilerplate code to pass execution flow into the
correct full function in the DLL.
<H3><A NAME="FOOT66" HREF="autobook_253.html#DOCF66">(66)</A></H3>
