|

default, <small>GDB</small> will be compiled if the Guile libraries are
|
||
|
|
installed and are found by <samp>configure</samp>. You can use the

<code>--with-guile</code> option to request Guile, and pass either the Guile

version number or the file name of the relevant <code>pkg-config</code>
|

program to choose a particular version of Guile.

<dt>iconv</dt>
|
||
|
|
<dd><p><small>GDB</small>’s features related to character sets (see <a href="Character-Sets.html#Character-Sets">Character Sets</a>) require a functioning <code>iconv</code> implementation. If you are
|
||
|
|
on a GNU system, then this is provided by the GNU C Library. Some
|
||
|
|
other systems also provide a working <code>iconv</code>.
|
||
|
|
</p>
|
||
|
|
<p>If <small>GDB</small> is using the <code>iconv</code> program which is installed
|
||
|
|
in a non-standard place, you will need to tell <small>GDB</small> where to
|
||
|
|
find it. This is done with <samp>--with-iconv-bin</samp> which specifies
|
||
|
|
the directory that contains the <code>iconv</code> program. This program is
|
||
|
|
run in order to make a list of the available character sets.
|
||
|
|
</p>
|
||
|
|
<p>On systems without <code>iconv</code>, you can install GNU Libiconv. If
|
||
|
|
Libiconv is installed in a standard place, <small>GDB</small> will
|
||
|
|
automatically use it if it is needed. If you have previously
|
||
|
|
installed Libiconv in a non-standard place, you can use the
|
||
|
|
<samp>--with-libiconv-prefix</samp> option to <samp>configure</samp>.
|
||
|
|
</p>
|
||
|
|
<p><small>GDB</small>’s top-level <samp>configure</samp> and <samp>Makefile</samp> will
|
||
|
|
arrange to build Libiconv if a directory named <samp>libiconv</samp> appears
|
||
|
|
in the top-most source directory. If Libiconv is built this way, and
|
||
|
|
if the operating system does not provide a suitable <code>iconv</code>
|
||
|
|
implementation, then the just-built library will automatically be used
|
||
|
|
by <small>GDB</small>. One easy way to set this up is to download GNU
|
||
|
|
Libiconv, unpack it inside the top-level directory of the <small>GDB</small>
|
||
|
|
source tree, and then rename the directory holding the Libiconv source
|
||
|
|
code to ‘<samp>libiconv</samp>’.

at <a href="http://tukaani.org/xz/">http://tukaani.org/xz/</a>. If the LZMA library is available in

<p>GNU MPFR is used to emulate target floating-point arithmetic during
