Update gdb's configure instructions
gdb's README and configure instructions in the manual are quite out of date. They mention options that haven't existed for many years, among other things. This patch attempts to modernize the instructions somewhat. It is not exhaustive, just an improvement -- more could be done. Perhaps even a couple of the nodes should simply be removed and replaced by references to the Autoconf manual. The README file seems to have been generated from the Texinfo at some point in the past. I did not continue this, but instead edited it separately. gdb/ChangeLog 2018-09-29 Tom Tromey <tom@tromey.com> * PROBLEMS: Rewrite. * README: Update. gdb/doc/ChangeLog 2018-09-29 Tom Tromey <tom@tromey.com> * gdb.texinfo (Requirements): Mention C++, GNU make.

If you get other compiler errors during this stage, see the `Reporting

Bugs' section below; there are a few known problems.

||||
|
||||
GDB requires an ISO C (ANSI C) compiler. If you do not have an ISO
|
||||
C compiler for your system, you may be able to download and install
|
||||
GDB's `configure' script has many options to enable or disable
|
||||
different features or dependencies. These options are not generally
|
||||
known to the top-level `configure', so if you want to see a complete
|
||||
list of options, invoke the subdirectory `configure', like:
|
||||
|
||||
/berman/migchain/source/gdb-VERSION/gdb/configure --help
|
||||
|
||||
(Take note of how this differs from the invocation used to actually
|
||||
configure the build tree.)
|
||||
|
||||
GDB requires a C++11 compiler. If you do not have a
|
||||
C++11 compiler for your system, you may be able to download and install
|
||||
the GNU CC compiler. It is available via anonymous FTP from the
|
||||
directory `ftp://ftp.gnu.org/pub/gnu/gcc'. GDB also requires an ISO
|
||||
C standard library. The GDB remote server, GDBserver, builds with some
|
||||
non-ISO standard libraries - e.g. for Windows CE.
|
||||
|
||||
GDB uses Expat, an XML parsing library, to implement some target-specific
|
||||
features. Expat will be linked in if it is available at build time, or
|
||||
those features will be disabled. The latest version of Expat should be
|
||||
available from `http://expat.sourceforge.net'.
|
||||
|
||||
GDB uses GNU MPFR, a library for multiple-precision floating-point
|
||||
computation with correct rounding, to emulate target floating-point
|
||||
arithmetic during expression evaluation when the target uses different
|
||||
floating-point formats than the host. MPFR will be linked in if it is
|
||||
available at build time. If GNU MPFR it is not available, GDB will fall
|
||||
back to using host floating-point arithmetic. The latest version of
|
||||
GNU MPFR should be available from `http://www.mpfr.org'.
|
||||
GDB can optionally be built against various external libraries.

These dependencies are described below in the "`configure options"
