Building GDB requires various tools and packages to be available. Other packages will be used only if they are found.
GDB is written in ISO C90. It should be buildable with any working C90 compiler, e.g. GCC.
GDB 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 http://expat.sourceforge.net. The configure script will search for this library in several standard locations; if it is installed in an unusual path, you can use the --with-libexpat-prefix option to specify its location.
Expat is used for:
GDB will use the ‘zlib’ library, if available, to read compressed debug sections. Some linkers, such as GNU gold, are capable of producing binaries with compressed debug sections. If GDB is compiled with ‘zlib’, it will be able to read the debug information in such binaries.
The ‘zlib’ library is likely included with your operating system distribution; if it is not, you can get the latest version from http://zlib.net.
GDB’s features related to character sets (see Character Sets) require a functioning
iconv implementation. If you are
on a GNU system, then this is provided by the GNU C Library. Some
other systems also provide a working
If GDB is using the
iconv program which is installed
in a non-standard place, you will need to tell GDB where to find it.
This is done with --with-iconv-bin which specifies the
directory that contains the
On systems without
iconv, you can install GNU Libiconv. If you
have previously installed Libiconv, you can use the
--with-libiconv-prefix option to configure.
GDB’s top-level configure and Makefile will
arrange to build Libiconv if a directory named libiconv appears
in the top-most source directory. If Libiconv is built this way, and
if the operating system does not provide a suitable
implementation, then the just-built library will automatically be used
by GDB. 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 ‘libiconv’.
