Problems with building [gdb 6.0]

Problems with building [gdb 6.0]

[Roland Zerek]

Hi,

I am writting this letter after few times I was trying to build gdb 6.0 from
sources. The environment is as follows:
*) operating system: winXP home edition
*) compiler: gcc 3.2 (CYGWIN 2.249.2.5)

It goes quite well for some time and then throws problems. Although I
understand messages,  I have no idea of how to solve problems reported. The
log of gdb build can be found at http://rolandz.fm.interia.pl/gdblog.html

Please anyone help me... TIA

Try building in a directory with no spaces in the pathname.  I don't
konw if that's supposed to work, but judging from the error messages,
it looks like it doesn't.

It should work but it is a frequent cause for complaint on cygwin, not
for anything to do with cygwin, but because most people on UNIX don't use
directories with spaces and so there are unknown assumptions in the build
process.  Of course, Windows loves to use directories with spaces in them.

And, btw, that's not a valid cygwin version number.  You can find the
version by typing 'uname -s'.

How about adding some blurb along these lines to INSTALL?

Output the filename ,the function name and the line number after returning from a function call

[murugesan]

Hello all,
	As you all know gdb outputs the filename ,the function name and the
line number after returning from a function call.
But this does not happen when a function has a parameter as another
function.

That is,
# gdb a.out
gdb> break main
gdb> s
     .
gdb> bt
     fun
     main
gdb> s
     .
     .

main (Argc=1, Argv=0x7e9f081c) at openssl.c:236
This is getting printed when returning from fun.
But this does not happen in the following case.

eg: 

fun(ret_val())
{
}

Here when returning from ret_val 
main (Argc=1, Argv=0x7e9f081c) at openssl.c:236 is not getting printed.
Instead it just enters fun function without returning main.

If it is the case ( that it will not return to main )
then my "bt" might have printed

ret_val
fun
main

But this does not happened for this case. Just it gave me

ret_val
main
Is there any way to make the gdb to output the filename ,the function
name and the line number after returning from functions that has another
function has parameter.

Thanks in advance for the help.

Regards,
Murugesan

Did you use the 'finish' command to return from the function call? Or do
you just do a 'next'? This might make a difference.

Re: Output the filename ,the function name and the line number after returning from a function call

[murugesan]

Thanks Bob.

I haven't explained much about my requirement.
Ofcourse finish does what you said.
Bud what I am doing is that

# gdb -x command | tee output
where command contains 1000000 number of "s" in it
So that I will get the flow from the beginning of the program to the end
including where I give the input...
So the output should contain the funs that has been called and returned.
The program MAY contain several such functions and I cannot point where
it occurs.

Thanks again for the reply and expecting the same again.

Re: Output the filename ,the function name and the line number after returning from a function call

[murugesan]

Thans for the reply Bob.
I haven't specified my requirement.

# gdb -x command | tee output

where command contains 1000's of "s" so that I can get all the output to
a file.
Ofcourse finish worked the way you said.
The problem is that there MAY be more functions like this.
I need to specify it in the file command

Thanks again for the reply and expecting the same again.
