This defaults to the +@file{gdb} subdirectory of @samp{datadi} (which can be set using +@code{--datadir}). + +@item --with-relocated-sources=@var{dir} +Sets up the default source path substitution rule so that directory +names recorded in debug information will be automatically adjusted for +any directory under @var{dir}. @var{dir} should be a subdirectory of +@value{GDBN}'s configured prefix, the one mentioned in the +@code{--prefix} or @code{--exec-prefix} options to configure.

See http://www.nongnu.org/libunwind/index.html for +details. + +@item --with-system-readline +Use the readline library installed on the host, rather than the +library supplied as part of @value{GDBN}. + +@item --with-system-zlib +Use the zlib library installed on the host, rather than the library +supplied as part of @value{GDBN}. + +@item --with-expat +Build @value{GDBN} with Expat, a library for XML parsing. (Done by +default if libexpat is installed and found at configure time.) This +library is used to read XML files supplied with @value{GDBN}. If it +is unavailable, some features, such as remote protocol memory maps, +target descriptions, and shared library lists, that are based on XML +files, will not be available in @value{GDBN}. If your host does not +have libexpat installed, you can get the latest version from +`http://expat.sourceforge.net'. + +@item --with-libiconv-prefix@r{[}=@var{dir}@r{]} + +Build @value{GDBN} with GNU libiconv, a character set encoding +conversion library. This is not done by default, as on GNU systems +the @code{iconv} that is built in to the C library is sufficient. If +your host does not have a working @code{iconv}, you can get the latest +version of GNU iconv from `https://www.gnu.org/software/libiconv/'. + +@value{GDBN}'s build system also supports building GNU libiconv as +part of the overall build. @xref{Requirements}. + +@item --with-lzma +Build @value{GDBN} with LZMA, a compression library. (Done by default +if liblzma is installed and found at configure time.) LZMA is used by +@value{GDBN}'s "mini debuginfo" feature, which is only useful on +platforms using the ELF object file format. If your host does not +have liblzma installed, you can get the latest version from +`https://tukaani.org/xz/'. + +@item --with-mpfr +Build @value{GDBN} with GNU MPFR, a library for multiple-precision +floating-point computation with correct rounding. (Done by default if +GNU MPFR is installed and found at configure time.) This library is +used to emulate target floating-point arithmetic during expression +evaluation when the target uses different floating-point formats than +the host. If GNU MPFR is not available, @value{GDBN} will fall back +to using host floating-point arithmetic. If your host does not have +GNU MPFR installed, you can get the latest version from +`http://www.mpfr.org'. + +@item --with-python@r{[}=@var{python}@r{]} +Build @value{GDBN} with Python scripting support. (Done by default if +libpython is present and found at configure time.) Python makes +@value{GDBN} scripting much more powerful than the restricted CLI +scripting language. If your host does not have Python installed, you +can find it on `http://www.python.org/download/'. The oldest version +of Python supported by GDB is 2.4. The optional argument @var{python} +is used to find the Python headers and libraries. It can be either +the name of a Python executable, or the name of the directory in which +Python is installed. + +@item --with-guile[=GUILE]' +Build @value{GDBN} with GNU Guile scripting support. (Done by default +if libguile is present and found at configure time.) If your host +does not have Guile installed, you can find it at +`https://www.gnu.org/software/guile/'. The optional argument GUILE +can be a version number, which will cause @code{configure} to try to +use that version of Guile; or the file name of a @code{pkg-config} +executable, which will be queried to find the information needed to +compile and link against Guile. + +@item --without-included-regex +Don't use the regex library included with @value{GDBN} (as part of the +libiberty library). This is the default on hosts with version 2 of +the GNU C library. + +@item --with-sysroot=@var{dir} +Use @var{dir} as the default system root directory for libraries whose +file names begin with @file{/lib}' or @file{/usr/lib'}. (The value of +@var{dir} can be modified at run time by using the @command{set +sysroot} command.) If @var{dir} is under the @value{GDBN} configured +prefix (set with @code{--prefix} or @code{--exec-prefix options}, the +default system root will be automatically adjusted if and when +@value{GDBN} is moved to a different location. + +@item --with-system-gdbinit=@var{file} +Configure @value{GDBN} to automatically load a system-wide init file. +@var{file} should be an absolute file name. If @var{file} is in a +directory under the configured prefix, and @value{GDBN} is moved to +another location after being built, the location of the system-wide +init file will be adjusted accordingly. + +@item --enable-build-warnings +When building the @value{GDBN} sources, ask the compiler to warn about +any code which looks even vaguely suspicious. It passes many +different warning flags, depending on the exact version of the +compiler you are using. + +@item --enable-werror +Treat compiler warnings as werrors. It adds the @code{-Werror} flag +to the compiler, which will fail the compilation if the compiler +outputs any warning messages. +@end table @node System-wide configuration @section System-wide configuration and settings |
