GDB can use the Expat XML parsing library. This library may be

can get the latest version from <A HREF="http://expat.sourceforge.net">http://expat.sourceforge.net</A>.
|
||
|
|
The <TT>`configure'</TT> script will search for this library in several
|

standard locations; if it is installed in an unusual path, you can
|
||
|
|
use the <SAMP>`--with-libexpat-prefix'</SAMP> option to specify its location.

<H2> B.2 Invoking the GDB <TT>`configure'</TT> Script </H2>
|
||
|
|
<!--docid::SEC689::-->
|
||
|
|
GDB comes with a <TT>`configure'</TT> script that automates the process
|
||
|
|
of preparing GDB for installation; you can then use <CODE>make</CODE> to
|
||
|
|
build the <CODE>gdb</CODE> program.
|
||
|
|
<P>
|
||
|
|
|
||
|
|
The GDB distribution includes all the source code you need for
|
||
|
|
GDB in a single directory, whose name is usually composed by
|
||
|
|
appending the version number to <SAMP>`gdb'</SAMP>.
|
||
|
|
</P><P>
|
||
|
|

For example, the GDB version 6.8 distribution is in the

<TT>`gdb-6.8'</TT> directory. That directory contains:

The simplest way to configure and build GDB is to run <TT>`configure'</TT>
|
||
|
|
from the <TT>`gdb-<VAR>version-number</VAR>'</TT> source directory, which in
|
||
|
|
this example is the <TT>`gdb-6.8'</TT> directory.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
First switch to the <TT>`gdb-<VAR>version-number</VAR>'</TT> source directory
|
||
|
|
if you are not already in it; then run <TT>`configure'</TT>. Pass the
|
||
|
|
identifier for the platform on which GDB will run as an
|
||
|
|
argument.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|

|

<TABLE><tr><td> </td><td class=smallexample><FONT SIZE=-1><pre>cd gdb-6.8

||
|

./configure <VAR>host</VAR>

||
|

make
|
||
|
|
</FONT></pre></td></tr></table></P><P>
|
||
|
|
|
||
|
|
where <VAR>host</VAR> is an identifier such as <SAMP>`sun4'</SAMP> or
|
||
|
|
<SAMP>`decstation'</SAMP>, that identifies the platform where GDB will run.
|
||
|
|
(You can often leave off <VAR>host</VAR>; <TT>`configure'</TT> tries to guess the
|
||
|
|
correct value by examining your system.)
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
Running <SAMP>`configure <VAR>host</VAR>'</SAMP> and then running <CODE>make</CODE> builds the
|
||
|
|
<TT>`bfd'</TT>, <TT>`readline'</TT>, <TT>`mmalloc'</TT>, and <TT>`libiberty'</TT>
|
||
|
|
libraries, then <CODE>gdb</CODE> itself. The configured source files, and the
|
||
|
|
binaries, are left in the corresponding source directories.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
<TT>`configure'</TT> is a Bourne-shell (<CODE>/bin/sh</CODE>) script; if your
|
||
|
|
system does not recognize this automatically when you run a different
|
||
|
|
shell, you may need to run <CODE>sh</CODE> on it explicitly:
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
<TABLE><tr><td> </td><td class=smallexample><FONT SIZE=-1><pre>sh configure <VAR>host</VAR>
|
||
|
|
</FONT></pre></td></tr></table></P><P>
|
||
|
|
|
||
|
|
If you run <TT>`configure'</TT> from a directory that contains source
|
||
|
|
directories for multiple libraries or programs, such as the
|
||
|
|
<TT>`gdb-6.8'</TT> source directory for version 6.8,
|
||
|
|
<TT>`configure'</TT>
|
||
|
|
creates configuration files for every directory level underneath (unless
|
||
|
|
you tell it not to, with the <SAMP>`--norecursion'</SAMP> option).
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
You should run the <TT>`configure'</TT> script from the top directory in the
|
||
|
|
source tree, the <TT>`gdb-<VAR>version-number</VAR>'</TT> directory. If you run
|
||
|
|
<TT>`configure'</TT> from one of the subdirectories, you will configure only
|
||
|
|
that subdirectory. That is usually not what you want. In particular,
|
||
|
|
if you run the first <TT>`configure'</TT> from the <TT>`gdb'</TT> subdirectory
|
||
|
|
of the <TT>`gdb-<VAR>version-number</VAR>'</TT> directory, you will omit the
|
||
|
|
configuration of <TT>`bfd'</TT>, <TT>`readline'</TT>, and other sibling
|
||
|
|
directories of the <TT>`gdb'</TT> subdirectory. This leads to build errors
|
||
|
|
about missing include files such as <TT>`bfd/bfd.h'</TT>.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
You can install <CODE>gdb</CODE> anywhere; it has no hardwired paths.
|
||
|
|
However, you should make sure that the shell on your path (named by
|
||
|
|
the <SAMP>`SHELL'</SAMP> environment variable) is publicly readable. Remember
|
||
|
|
that GDB uses the shell to start your program--some systems refuse to
|
||
|
|
let GDB debug child processes whose programs are not readable.

<H2> B.3 Compiling GDB in Another Directory </H2>
|
||
|
|
<!--docid::SEC690::-->
|
||
|
|
<P>
|
||
|
|
|
||
|
|
If you want to run GDB versions for several host or target machines,
|
||
|
|
you need a different <CODE>gdb</CODE> compiled for each combination of
|
||
|
|
host and target. <TT>`configure'</TT> is designed to make this easy by
|
||
|
|
allowing you to generate each configuration in a separate subdirectory,
|
||
|
|
rather than in the source directory. If your <CODE>make</CODE> program
|
||
|
|
handles the <SAMP>`VPATH'</SAMP> feature (GNU <CODE>make</CODE> does), running
|
||
|
|
<CODE>make</CODE> in each of these directories builds the <CODE>gdb</CODE>
|
||
|
|
program specified there.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
To build <CODE>gdb</CODE> in a separate directory, run <TT>`configure'</TT>
|
||
|
|
with the <SAMP>`--srcdir'</SAMP> option to specify where to find the source.
|
||

(You also need to specify a path to find <TT>`configure'</TT>
|
||
|
|
itself from your working directory. If the path to <TT>`configure'</TT>
|
||
|
|
would be the same as the argument to <SAMP>`--srcdir'</SAMP>, you can leave out

the <SAMP>`--srcdir'</SAMP> option; it is assumed.)

For example, with version 6.8, you can build GDB in a
|
||
|
|
separate directory for a Sun 4 like this:

When <TT>`configure'</TT> builds a configuration using a remote source
|
||
|
|
directory, it creates a tree for the binaries with the same structure
|
||
|
|
(and using the same names) as the tree under the source directory. In
|
||
|
|
the example, you'd find the Sun 4 library <TT>`libiberty.a'</TT> in the
|
||
|
|
directory <TT>`gdb-sun4/libiberty'</TT>, and GDB itself in
|
||
|
|
<TT>`gdb-sun4/gdb'</TT>.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
Make sure that your path to the <TT>`configure'</TT> script has just one
|
||
|
|
instance of <TT>`gdb'</TT> in it. If your path to <TT>`configure'</TT> looks
|
||
|
|
like <TT>`../gdb-6.8/gdb/configure'</TT>, you are configuring only
|
||
|
|
one subdirectory of GDB, not the whole package. This leads to
|
||
|
|
build errors about missing include files such as <TT>`bfd/bfd.h'</TT>.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
One popular reason to build several GDB configurations in separate
|
||
|
|
directories is to configure GDB for cross-compiling (where
|
||
|
|
GDB runs on one machine--the <EM>host</EM>---while debugging
|
||
|
|
programs that run on another machine--the <EM>target</EM>).
|
||
|
|
You specify a cross-debugging target by
|
||
|
|
giving the <SAMP>`--target=<VAR>target</VAR>'</SAMP> option to <TT>`configure'</TT>.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
When you run <CODE>make</CODE> to build a program or library, you must run
|
||
|
|
it in a configured directory--whatever directory you were in when you
|
||
|
|
called <TT>`configure'</TT> (or one of its subdirectories).
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
The <CODE>Makefile</CODE> that <TT>`configure'</TT> generates in each source
|
||
|
|
directory also runs recursively. If you type <CODE>make</CODE> in a source
|
||
|
|
directory such as <TT>`gdb-6.8'</TT> (or in a separate configured
|
||
|
|
directory configured with <SAMP>`--srcdir=<VAR>dirname</VAR>/gdb-6.8'</SAMP>), you
|
||
|
|
will build all the required libraries, and then build GDB.
|
||
|
|
</P><P>
|
||
|
|
|
||
|
|
When you have multiple hosts or targets configured in separate
|
||
|
|
directories, you can run <CODE>make</CODE> on them in parallel (for example,
|
||
|
|
if they are NFS-mounted on each of the hosts); they will not interfere
|
||
|
|
with each other.

The specifications used for hosts and targets in the <TT>`configure'</TT>
|
||
|
|
script are based on a three-part naming scheme, but some short predefined
|
||
|
|
aliases are also supported. The full naming scheme encodes three pieces
|
||
|
|
of information in the following pattern:
|
||
|
|
</P><P>

|
||
|
|
</FONT></pre></td></tr></table></P><P>
|
||
|
|
|
||
|
|
For example, you can use the alias <CODE>sun4</CODE> as a <VAR>host</VAR> argument,
|
||
|
|
or as the value for <VAR>target</VAR> in a <CODE>--target=<VAR>target</VAR></CODE>
|
||
|
|
option. The equivalent full name is <SAMP>`sparc-sun-sunos4'</SAMP>.

</P><P>
|

|
|
|

|
|
The <TT>`configure'</TT> script accompanying GDB does not provide
|
||
|
|
any query facility to list all supported host and target names or
|
||
|
|
aliases. <TT>`configure'</TT> calls the Bourne shell script
|
||
|
|
<CODE>config.sub</CODE> to map abbreviations to full names; you can read the
|
||
|

script, if you wish, or you can use it to test your guesses on
|

abbreviations--for example:
