Short gdb question.

Short gdb question.

[eric_justin_allan]

Is this the right place to suggest that gdb be upgraded for cygwin. If 
not where could I suggest that? If this is an acceptable place then can 
I add here that if you guys do upgrade gdb that I was hoping you could 
make it a bit more detailed maybe make it to show a bit more information 
about crashes. An example is that I m working with a linked list and 
when the program crashes gdb prints out and only prints out the words 
below this text. I am left clueless about the error.

Program received signal SIGABRT, Aborted.
0x7ffe0304 in ?? ()

This happens only with SIGABRT, AFAIK. You can work around it by setting 
a breakpoint on "_abort" which will catch the problem before the stack 
gets lost in windows-land.

For SIGSEGV (usually an unintentional error), gdb usually does the right 
thing and gives you the offending stack trace.

...and find out that the above behavior will not change in any way in the
new version of gdb.

Incidentally, I just resigned as the gdb maintainer for Windows.

Anyone else want to take on the mantle?

Alright if I download and compile it can I just mv gdb.exe into /bin and 
overwrite gdb.exe?

use
./configure --prefix=/
make
make install

and it should end up in the right place

I actually usually use

./configure --prefix=/usr


and everything ends up in the correct place

I always put stuff like this in ~/apps/$APP_NAME-$VERSION and add the 
appropriate bits to PATH, LD_LIBRARY_PATH and MANPATH... then later when 
I decide to upgrade/change/revert it's a simple matter of changing 
environment veriables...

It has already been stated that the configure prefix should be stated
as --prefix='' to avoid
