You can run the @code{configure} script from any of the
subordinate directories in the @value{GDBN} distribution if you only want to
configure that subdirectory, but be sure to specify a path to it.
For example, with version @value{GDBVN}, type the following to configure only
the @code{bfd} subdirectory:
@smallexample
@group
cd gdb-@value{GDBVN}/bfd
../configure @var{host}
@end group

You should run the @code{configure} script from the top directory in the
source tree, the @file{gdb-@var{version-number}} directory. If you run
@code{configure} 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 @code{configure} from the @file{gdb} subdirectory
of the @file{gdb-@var{version-number}} directory, you will omit the
configuration of @file{bfd}, @file{readline}, and other sibling
directories of the @file{gdb} subdirectory. This leads to build errors
about missing include files such as @file{bfd/bfd.h}.

Make sure that your path to the @file{configure} script has just one
instance of @file{gdb} in it. If your path to @file{configure} looks
like @file{../gdb-@value{GDBVN}/gdb/configure}, you are configuring only
one subdirectory of @value{GDBN}, not the whole package. This leads to
build errors about missing include files such as @file{bfd/bfd.h}.
One popular reason to build several @value{GDBN} configurations in separate
directories is to configure @value{GDBN} for cross-compiling (where
