Color codes in GDB-GUD

Color codes in GDB-GUD

[Florian Lindner]

Hello,

when working with gdb, started using M-x gdb with -annotate=1 I have color codes ^Z^Z everywhere, like:

^Z^Z\x1a\x1a/home/florian/precice/src/mapping/PetRadialBasisFctMapping.hpp:803:31382:beg:0x11668d9

How can I get rid of them?

gdb 7.12.1 / Emacs 25.1.1

Best Thanks,
Florian

Does it help to invoke "M-x gud-gdb RET" instead?

Hello,

that does seem to fix that issue.

However:

- clicking on the fringe to set a breakpoint does not work anymore
- gdb-many-windows seems to be unavailable.

What is the difference between gdb and gud-gdb?

Thanks,
Florian

Of course, because gud-gdb doesn't support this fancy new stuff.  If
you want those features, then invoke GDB with "M-x gdb RET", but do
NOT add the -annotate=1 option to the GDB command line.  Instead,
leave the command line as Emacs offers, i.e "gdb -i=mi", and only edit
the name of the program you want to debug, if needed.  The -i=mi part
activates an alternative method of communicating with GDB that doesn't
need the annotations, and that ^Z^Z^Z^Z stuff is produced by
annotations.

gud-gdb is the old gdb command, which uses annotations; gdb is a new
command which uses the GDB/MI interface for communicating with GDB,
and supports new GUI features in the Emacs GDB front-end.

You need to decide whether you want annotations or the new GUI
features; they cannot be had together.

Ah, thanks. I read in all docs to use annotate=1, now it works.

Next step is to tell gdb-mi.el not to fuck with my windows (make windows dedicated, randomly create new frames).

Best,
Florian

I don't think you can, gdb-mi.el usurps the frame in which you invoke
it and makes its windows dedicated on purpose.  For best results make
its frame maximized.

My suggestion is to run gdb-mi in a separate frame, so that your other
frame(s) are left intact, as much as possible.
