As discussed here [1], do some re-work in the "set debuginfod commands".
First, use "set debuginfod enabled on/off/ask" instead of "set
debuginfod on/off/ask". This is more MI-friendly, and it gives an
output that makes more sense in "info set", for example.
Then, make the show commands not call "error" when debuginfod support is
not compiled in. This makes the commands "show" and "show debuginfod"
stop early, breaking gdb.base/default.exp:
Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/default.exp ...
FAIL: gdb.base/default.exp: info set
FAIL: gdb.base/default.exp: show
- Make the "debuginfod enabled" setting default to "off" when debuginfod
support is not compiled in, and "ask" otherwise.
- Make the setter of "debuginfod enabled" error out when debuginfod
support is not compiled in, so that "debuginfod enabled" will always
remain "off" in that case.
- Make the setter of "debuginfod verbose" work in any case. I don't
see the harm in letting the user change that setting, since the user will
hit an error if they try to enable the use of debuginfod.
- I would do the same for the "debuginfod urls" setter, but because
this one needs to see the DEBUGINFOD_URLS_ENV_VAR macro, provided by
libdebuginfod, I made that one error out as well if debuginfod
support is not compiled it (otherwise, I would have left it like
"debuginfod verbose". Alternatively, we could hard-code
"DEBUGINFOD_URLS" in the code (in fact, it was prior to this patch,
but I think it was an oversight, as other spots use
DEBUGINFOD_URLS_ENV_VAR), or use a dummy string to store the setting,
but I don't really see the value in that.
Rename debuginfod_enable to debuginfod_enabled, just so it matches the
setting name.

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.
