[Magic-dev] gdb & ddd

[cfk]

Dear Tim:
    A year ago, you were kind enough to point out the use of gdb or ddd to step through some of the magic code. This morning, I went back through my notes and I found:

ddd wish
run
set argv {-w}
set argc 1
source /usr/local/lib/magic/tcl/magic.tcl

I can do that and get the magic window up on my screen.

At this point, I want to try to break at the main loop that services commands so I can loop at execution of things like box, paint and others. But, unfortunately, my notes (normally quite good) leave out this all-important last step.

Additionally, I would like to step through the startup code again in main.c that services initbeforeargs, doargs and initafterargs.

I am hoping you might be willing to process a paragraph or so and help me get back to where I can single step through magic with ddd.

With Respect, Charles
