| <h3 class="section">27.19 <span class="sc">gdb/mi</span> File Commands</h3> |
| |
| <p>This section describes the GDB/MI commands to specify executable file names |
| and to read in and obtain symbol table information. |
| |
| <h4 class="subheading">The <code>-file-exec-and-symbols</code> Command</h4> |
| |
| <p><a name="index-g_t_002dfile_002dexec_002dand_002dsymbols-3065"></a> |
| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <pre class="smallexample"> -file-exec-and-symbols <var>file</var> |
| </pre> |
| <p>Specify the executable file to be debugged. This file is the one from |
| which the symbol table is also read. If no file is specified, the |
| command clears the executable and symbol information. If breakpoints |
| are set when using this command with no arguments, <span class="sc">gdb</span> will produce |
| error messages. Otherwise, no output is produced, except a completion |
| notification. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <p>The corresponding <span class="sc">gdb</span> command is ‘<samp><span class="samp">file</span></samp>’. |
| |
| <h5 class="subsubheading">Example</h5> |
| |
| <pre class="smallexample"> (gdb) |
| -file-exec-and-symbols /kwikemart/marge/ezannoni/TRUNK/mbx/hello.mbx |
| ^done |
| (gdb) |
| </pre> |
| <h4 class="subheading">The <code>-file-exec-file</code> Command</h4> |
| |
| <p><a name="index-g_t_002dfile_002dexec_002dfile-3066"></a> |
| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <pre class="smallexample"> -file-exec-file <var>file</var> |
| </pre> |
| <p>Specify the executable file to be debugged. Unlike |
| ‘<samp><span class="samp">-file-exec-and-symbols</span></samp>’, the symbol table is <em>not</em> read |
| from this file. If used without argument, <span class="sc">gdb</span> clears the information |
| about the executable file. No output is produced, except a completion |
| notification. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <p>The corresponding <span class="sc">gdb</span> command is ‘<samp><span class="samp">exec-file</span></samp>’. |
| |
| <h5 class="subsubheading">Example</h5> |
| |
| <pre class="smallexample"> (gdb) |
| -file-exec-file /kwikemart/marge/ezannoni/TRUNK/mbx/hello.mbx |
| ^done |
| (gdb) |
| </pre> |
| <h4 class="subheading">The <code>-file-list-exec-source-file</code> Command</h4> |
| |
| <p><a name="index-g_t_002dfile_002dlist_002dexec_002dsource_002dfile-3067"></a> |
| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <pre class="smallexample"> -file-list-exec-source-file |
| </pre> |
| <p>List the line number, the current source file, and the absolute path |
| to the current source file for the current executable. The macro |
| information field has a value of ‘<samp><span class="samp">1</span></samp>’ or ‘<samp><span class="samp">0</span></samp>’ depending on |
| whether or not the file includes preprocessor macro information. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <p>The <span class="sc">gdb</span> equivalent is ‘<samp><span class="samp">info source</span></samp>’ |
| |
| <h5 class="subsubheading">Example</h5> |
| |
| <pre class="smallexample"> (gdb) |
| 123-file-list-exec-source-file |
| 123^done,line="1",file="foo.c",fullname="/home/bar/foo.c,macro-info="1" |
| (gdb) |
| </pre> |
| <h4 class="subheading">The <code>-file-list-exec-source-files</code> Command</h4> |
| |
| <p><a name="index-g_t_002dfile_002dlist_002dexec_002dsource_002dfiles-3068"></a> |
| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <pre class="smallexample"> -file-list-exec-source-files |
| </pre> |
| <p>List the source files for the current executable. |
| |
| <p>It will always output both the filename and fullname (absolute file |
| name) of a source file. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <p>The <span class="sc">gdb</span> equivalent is ‘<samp><span class="samp">info sources</span></samp>’. |
| <code>gdbtk</code> has an analogous command ‘<samp><span class="samp">gdb_listfiles</span></samp>’. |
| |
| <h5 class="subsubheading">Example</h5> |
| |
| <pre class="smallexample"> (gdb) |
| -file-list-exec-source-files |
| ^done,files=[ |
| {file=foo.c,fullname=/home/foo.c}, |
| {file=/home/bar.c,fullname=/home/bar.c}, |
| {file=gdb_could_not_find_fullpath.c}] |
| (gdb) |
| </pre> |
| <h4 class="subheading">The <code>-file-list-shared-libraries</code> Command</h4> |
| |
| <p><a name="index-g_t_002dfile_002dlist_002dshared_002dlibraries-3069"></a> |
| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <pre class="smallexample"> -file-list-shared-libraries [ <var>regexp</var> ] |
| </pre> |
| <p>List the shared libraries in the program. |
| With a regular expression <var>regexp</var>, only those libraries whose |
| names match <var>regexp</var> are listed. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <p>The corresponding <span class="sc">gdb</span> command is ‘<samp><span class="samp">info shared</span></samp>’. The fields |
| have a similar meaning to the <code>=library-loaded</code> notification. |
| The <code>ranges</code> field specifies the multiple segments belonging to this |
| library. Each range has the following fields: |
| |
| <dl> |
| <dt>‘<samp><span class="samp">from</span></samp>’<dd>The address defining the inclusive lower bound of the segment. |
| <br><dt>‘<samp><span class="samp">to</span></samp>’<dd>The address defining the exclusive upper bound of the segment. |
| </dl> |
| |
| <h5 class="subsubheading">Example</h5> |
| |
| <pre class="smallexample"> (gdb) |
| -file-list-exec-source-files |
| ^done,shared-libraries=[ |
| {id="/lib/libfoo.so",target-name="/lib/libfoo.so",host-name="/lib/libfoo.so",symbols-loaded="1",thread-group="i1",ranges=[{from="0x72815989",to="0x728162c0"}]}, |

| (gdb) |
| </pre> |
| <h4 class="subheading">The <code>-file-symbol-file</code> Command</h4> |
| |
| <p><a name="index-g_t_002dfile_002dsymbol_002dfile-3070"></a> |
| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <pre class="smallexample"> -file-symbol-file <var>file</var> |
| </pre> |
| <p>Read symbol table info from the specified <var>file</var> argument. When |
| used without arguments, clears <span class="sc">gdb</span>'s symbol table info. No output is |
| produced, except for a completion notification. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <p>The corresponding <span class="sc">gdb</span> command is ‘<samp><span class="samp">symbol-file</span></samp>’. |
| |
| <h5 class="subsubheading">Example</h5> |
| |
| <pre class="smallexample"> (gdb) |
