| Building <span class="sc">gdb</span> requires various tools and packages to be available. |
| Other packages will be used only if they are found. |
| |
| <h3 class="heading">Tools/Packages Necessary for Building <span class="sc">gdb</span></h3> |
| |
| <dl> |
| <dt>ISO C90 compiler<dd><span class="sc">gdb</span> is written in ISO C90. It should be buildable with any |
| working C90 compiler, e.g. GCC. |
| |
| </dl> |

| <h3 class="heading">Tools/Packages Optional for Building <span class="sc">gdb</span></h3> |

| <dl> |
| <dt>Expat<dd><a name="Expat"></a><span class="sc">gdb</span> can use the Expat XML parsing library. This library may be |
| included with your operating system distribution; if it is not, you |
| can get the latest version from <a href="http://expat.sourceforge.net">http://expat.sourceforge.net</a>. |
| The <samp><span class="file">configure</span></samp> script will search for this library in several |
| standard locations; if it is installed in an unusual path, you can |
| use the <samp><span class="option">--with-libexpat-prefix</span></samp> option to specify its location. |
| |
| <p>Expat is used for: |
| |
| <ul> |
| <li>Remote protocol memory maps (see <a href="Memory-Map-Format.html#Memory-Map-Format">Memory Map Format</a>) |
| <li>Target descriptions (see <a href="Target-Descriptions.html#Target-Descriptions">Target Descriptions</a>) |
| <li>Remote shared library lists (see <a href="Library-List-Format.html#Library-List-Format">Library List Format</a>) |
| <li>MS-Windows shared libraries (see <a href="Shared-Libraries.html#Shared-Libraries">Shared Libraries</a>) |
| </ul> |
| |
| <br><dt>zlib<dd><a name="index-compressed-debug-sections-2297"></a><span class="sc">gdb</span> will use the ‘<samp><span class="samp">zlib</span></samp>’ library, if available, to read |
| compressed debug sections. Some linkers, such as GNU gold, are capable |
| of producing binaries with compressed debug sections. If <span class="sc">gdb</span> |
| is compiled with ‘<samp><span class="samp">zlib</span></samp>’, it will be able to read the debug |
| information in such binaries. |
| |
| <p>The ‘<samp><span class="samp">zlib</span></samp>’ library is likely included with your operating system |
| distribution; if it is not, you can get the latest version from |
| <a href="http://zlib.net">http://zlib.net</a>. |
| |
| <br><dt>iconv<dd><span class="sc">gdb</span>'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>On systems with <code>iconv</code>, you can install GNU Libiconv. If you |
| have previously installed Libiconv, you can use the |
| <samp><span class="option">--with-libiconv-prefix</span></samp> option to configure. |
| |
| <p><span class="sc">gdb</span>'s top-level <samp><span class="file">configure</span></samp> and <samp><span class="file">Makefile</span></samp> will |
| arrange to build Libiconv if a directory named <samp><span class="file">libiconv</span></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 <span class="sc">gdb</span>. One easy way to set this up is to download GNU |
| Libiconv, unpack it, and then rename the directory holding the |
| Libiconv source code to ‘<samp><span class="samp">libiconv</span></samp>’. |
