--- Comment #6 from Pádraig Brady <P at draigBrady dot com> ---
As per the mail linked in comment #1 I see this when sourcing commands, where
the breakpoint commands aren't run unless an interactive prompt is displayed
first. I.E. if I pass `--eval-command='source breakpoint_file_with_commands'
--eval-command=run` the commands associated with a breakpoint aren't run, while
if I issue the "run" from the interactive prompt they are.

            Bug ID: 19149
           Summary: Message when guile is required but not available  is
                    not clear
           Product: gdb
           Version: 7.10
            Status: NEW
          Severity: normal
          Priority: P2
         Component: guile
          Assignee: unassigned at sourceware dot org
          Reporter: yuri at tsoft dot com
  Target Milestone: ---

I have gdb-7.10 built without the GUILE option (which is the default) on
FreeBSD. Qt4 project (.pro) automatically runs the following command that
fails:

> $ gdb --nx --batch --quiet -ex 'set confirm off' -ex "save gdb-index $DESTDIR" -ex quit 'xxx'
> Exception caught while booting Guile.
> Error in function "open-file":
> No such file or directory: "/usr/local/share/gdb710/guile/gdb/boot.scm"
> gdb: warning: Could not complete Guile gdb module initialization from:
> /usr/local/share/gdb710/guile/gdb/boot.scm.
> Limited Guile support is available.
> Suggest passing --data-directory=/path/to/gdb/data-directory.
> usage: save gdb-index DIRECTORY


gdb error message should say: "guile is required for the operation <whatever>,
but gdb hasn't been built with guile support. Please choose an option
--with-guile to build gdb with guile support."

People have to deal with a lot of interacting systems, that is why error
message should be as clear and informative as possible.

[Bug mi/10079] Commands attached to a breakpoint do not execute in MI mode

It turned out to be very easy.

I went to <build>/gdb/testsuite and typed

    make check

With this "top.c" update, there is one extra failure :

FAIL: gdb.threads/schedlock.exp: other threads ran - unlocked

The whole picture looks like this:

Latest X86 FSF :

		=== gdb Summary ===

# of expected passes		13400
# of unexpected failures	74
# of expected failures		41
# of known failures		61
# of unresolved testcases	3
# of untested testcases		7
# of unsupported tests		8

Latest X86 FSF with "top.c" update :

		=== gdb Summary ===

# of expected passes		13399
# of unexpected failures	75
# of expected failures		41
# of known failures		61
# of unresolved testcases	3
# of untested testcases		7
# of unsupported tests		8

Hello Nik,

> Have you run the testsuite against this change?

No I did not. Can you give me a brief instruction, 
please, on how to run DejaGnu tests against FSF X86 GDB ?

I run all kind of tests against GDB, but all these setups
are different from native X86 FSF.

Thanks,
-- Maxim

Have you run the testsuite against this change?

Yes, it seems to work fine. Only, it did not apply directly.

I had to modify it like this :

So what should be done now ? Is it going to be applied against the top of the
