debugger / strace / emacs

[Matthias Schmidt]

Hi *,

I've managed to build emacs 24.5 on minix 3.3 with some slight modifications. When i start the program nothing happens. Not even a coredump. Simply nothing. The --version and --help flags churn out there output, but no screen shows up if i start without parameters or files to edit. I've build it with this configure line:

CFLAGS=-O0 ./configure --without-pop --with-x-toolkit=no --without-all --build=x86_64-unknown-netbsd

Besides this i had to apply these patches ( just to get it build for now, not a long-term solution ):

- remove movemail-build from lib-src/Makefile

- null-implement network_interface_list and network_interface_info in src/process.c

Now I'm desperately looking for a debugger plus something like strace. Or is there another way to nail this down I have overlooked?

Or is there a emacs-guru on the list helping me to troubleshoot the lisp part of the show ...?

cheers,

Matthias Schmidt

As of last fall, MINIX3 has a trace(1) system call tracer. It is part of the latest development snapshot:

I'm afraid I cannot help with your other questions..

Hi David,

and thanks for the super-fast reply! Having a systemcall tracer is a good thing, but i doubt that i can narrow down my problem by tracing systemcalls.

Having no userland-debugger makes me really wonder how i am supposed to port or develop applications on minx. And aren't applications the reason for operating systems?

To keep it short: First things first: Debuggers and Editors to get things going.

@all: Are there people working on the llvm debugger for minix?

cheers,

Matthias
