Starting the GDB server (#adhd problems lol)

[Corbin]

Hey all,

I'm trying to set up GDB so I can follow stack traces, but I have completely forgotten how to do this :S

I have my engine set up to compile with -g so it can generate these. I'm using dc-tool IP GUI V2 to send the
ELF to dcload-IP 1.0.5. While it normally works fine, trying to set the option to start the GDB server in dctool-gui v2
doesn't actually seem to do anything.

Now, I know for a fact I got this working before, it's just been so long and my ADHD just makes me forget everything
I learn.

So, this is what my console output looks like right now:

Starting a GDB server on port 2159

waiting for gdb client connection...

And it just hangs there. Dreamcast shows black screen. Shouldn't there be another window or something that
should be starting? Or do I need to use a different dc-tool IP GUI (I'm using v2)?

Thanks guys <3

I'd assume that you need to start up GDB in a terminal to connect to localhost on port 2159 (at least in that example that you showed).

I've never used any GUIs for dc-tool, but that seems like it would hopefully be the logical next step.

Thanks, I got it all figured out!!

So now GDB works great, but I'm trying to install Insight. I've copied Insight to:

\opt\toolchains\dc\kos\utils\dc-chain\insight-6.8-1

Did a ./configure, worked great.

Attempting to Make it gave me these errors:

Any ideas? It doesn't seem too helpful in figuring out what went wrong here. . . Thanks!

I've never messed around with Insight (never messed around with GDB for Dreamcast stuff period), but it looks like it's failing trying to build documentation for libbfd.

Unfortunately, I haven't messed with it to know what to do to fix it. My initial instinct would be to try to get it so it doesn't build the documentation, since I'm sure you don't actually need libbfd's documentation to run Insight. How you'd go about that, I don't know. Perhaps someone else could share their insight on the topic (hooray for bad puns?).

Okay, quick solution for anyone else running into trouble -- I went to:

opt\toolchains\dc\kos\utils\dc-chain\insight-6.8-1\bfd\doc\

Opened up elf.texi, and the line (should be 11):

@subsubsection @code(bdf_elf_find_section)

Just change that line to:

@subsection @code{bfd_elf_find_section}

Seems to run fine, but now I have that stupid bfd_set_cacheable problem, I seem to remember it being referenced somewhere on here... ^_^
