'gdb --configuration' does not mention if GDB was built with curses. Since b5075fb68d4 (Rename to allow_tui_tests, 2023-01-08) it does show --enable-tui (or --disable-tui), but one might want to know if GDB was built with curses independently of the availability of the TUI. Since configure.ac uses AC_SEARCH_LIBS to check for the curses library, we do not get an automatically defined HAVE_LIBCURSES symbol in config.in. We do have symbols defined by AC_CHECK_HEADERS (HAVE_CURSES_H, etc.) but it would be cumbersome to use those in print_gdb_configuration because we would have to check for all 6 symbols corresponding the 6 headers listed. This would also increase the maintenance burden if support for other variations of curses are added. Instead, define 'HAVE_LIBCURSES' ourselves by adding an 'action-if-found' argument to AC_SEARCH_LIBS, and use it in print_gdb_configuration. While at it, remove the condition on 'ac_cv_search_waddstr' and set 'curses_found' directly in 'action-if-found'.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
