<p><a name="index-g_t_0040value_007bGDBN_007d-reference-card-3296"></a><a name="index-reference-card-3297"></a>The <span class="sc">gdb</span> 4 release includes an already-formatted reference card, ready
|
|
for printing with PostScript or Ghostscript, in the <samp><span class="file">gdb</span></samp>
|
|
subdirectory of the main source directory<a rel="footnote" href="#fn-1" name="fnd-1"><sup>1</sup></a>. If you can use PostScript or Ghostscript with your printer,
|
|
you can print the reference card immediately with <samp><span class="file">refcard.ps</span></samp>.
|
|
|
|
<p>The release also includes the source for the reference card. You
|
|
can format it, using TeX, by typing:
|
|
|
|
<pre class="smallexample"> make refcard.dvi
|
|
</pre>
|
|
<p>The <span class="sc">gdb</span> reference card is designed to print in <dfn>landscape</dfn>
|
|
mode on US “letter” size paper;
|
|
that is, on a sheet 11 inches wide by 8.5 inches
|
|
high. You will need to specify this form of printing as an option to
|
|
your <span class="sc">dvi</span> output program.
|
|
|
|
<p><a name="index-documentation-3298"></a>
|
|
All the documentation for <span class="sc">gdb</span> comes as part of the machine-readable
|
|
distribution. The documentation is written in Texinfo format, which is
|
|
a documentation system that uses a single source file to produce both
|
|
on-line information and a printed manual. You can use one of the Info
|
|
formatting commands to create the on-line version of the documentation
|
|
and TeX (or <code>texi2roff</code>) to typeset the printed version.
|
|
|
|
<p><span class="sc">gdb</span> includes an already formatted copy of the on-line Info
|
|
version of this manual in the <samp><span class="file">gdb</span></samp> subdirectory. The main Info
|
|
file is <samp><span class="file">gdb-8.3.0.20190709-git/gdb/gdb.info</span></samp>, and it refers to
|
|
subordinate files matching ‘<samp><span class="samp">gdb.info*</span></samp>’ in the same directory. If
|
|
necessary, you can print out these files, or read them with any editor;
|
|
but they are easier to read using the <code>info</code> subsystem in <span class="sc">gnu</span>
|
|
Emacs or the standalone <code>info</code> program, available as part of the
|
|
<span class="sc">gnu</span> Texinfo distribution.
|
|
|
|
<p>If you want to format these Info files yourself, you need one of the
|
|
Info formatting programs, such as <code>texinfo-format-buffer</code> or
|
|
<code>makeinfo</code>.
|
|
|
|
<p>If you have <code>makeinfo</code> installed, and are in the top level
|
|
<span class="sc">gdb</span> source directory (<samp><span class="file">gdb-8.3.0.20190709-git</span></samp>, in the case of
|
|
version 8.3.0.20190709-git), you can make the Info file by typing:
|
|
|
|
<pre class="smallexample"> cd gdb
|
|
make gdb.info
|
|
</pre>
|
|
<p>If you want to typeset and print copies of this manual, you need TeX,
|
|
a program to print its <span class="sc">dvi</span> output files, and <samp><span class="file">texinfo.tex</span></samp>, the
|
|
Texinfo definitions file.
|
|
|
|
<p>TeX is a typesetting program; it does not print files directly, but
|
|
produces output files called <span class="sc">dvi</span> files. To print a typeset
|
|
document, you need a program to print <span class="sc">dvi</span> files. If your system
|
|
has TeX installed, chances are it has such a program. The precise
|
|
command to use depends on your system; <kbd>lpr -d</kbd> is common; another
|
|
(for PostScript devices) is <kbd>dvips</kbd>. The <span class="sc">dvi</span> print command may
|
|
require a file name without any extension or a ‘<samp><span class="samp">.dvi</span></samp>’ extension.
|
|
|
|
<p>TeX also requires a macro definitions file called
|
|
<samp><span class="file">texinfo.tex</span></samp>. This file tells TeX how to typeset a document
|
|
written in Texinfo format. On its own, TeX cannot either read or
|
|
typeset a Texinfo file. <samp><span class="file">texinfo.tex</span></samp> is distributed with GDB
|
|
and is located in the <samp><span class="file">gdb-</span><var>version-number</var><span class="file">/texinfo</span></samp>
|
|
directory.
|
|
|
|
<p>If you have TeX and a <span class="sc">dvi</span> printer program installed, you can
|
|
typeset and print this manual. First switch to the <samp><span class="file">gdb</span></samp>
|
|
subdirectory of the main source directory (for example, to
|
|
<samp><span class="file">gdb-8.3.0.20190709-git/gdb</span></samp>) and type:
|
|
|
|
<pre class="smallexample"> make gdb.dvi
|
|
</pre>
|
|
<p>Then give <samp><span class="file">gdb.dvi</span></samp> to your <span class="sc">dvi</span> printing program.
