arc argv problems

arc argv problems

[Lee]

I am doing all of this on linux gdb build 
gdb-6.5.50.20060823

I dumbed down my script for demo purposes here
I even downloaded some sample .gdbinit files and they
did not work either

I am not sure if this is a bug, or user error

.gdbinit
#-----------------------------------------------
set prompt # 

define alf
     printf "%d\n", $argc
end

define u
        if $argc == 0
                x/10i $_
        end
        if $f $argc == 1
                x/10i $_
        end
        if $argc == 1
                x/10i $arg1
        end
        white
end

edircpr:/gdb/gdb-6.5.50.20060823/gdb # vi ~/.gdbinit

 #:  u
Invalid type combination in equality test.

Notice how the $argc isnt correct, and even changes
sometimes

I also can not do anything like if $argc == 2 etc as I
get the invalid type errors.

my goal with the script here is that I can ofcourse
tell how may args were passed to my user defined
function and work with said args

I have also tried using $ARGC etc, but I think the
correct one to use is $argc $argv

Any suggestions ?

Also I have not found any good scripting references
specific to gdb.  While it is very similar to other
things, there are things that work special like printf
that are close but not the same.

Thanks
Lee

Your GDB appears to be very, very broken.  I get completely different
results using the same gdbinit, which look correct.

You appear to have edited out your platform.  Where are you running
this?

$argc and $arg0 and $arg1.

It's all in the GDB manual.  Search for $argc.
