Change to allow MSVC2012 x64 build

simongemm...@gmail.com (gemmell) — Tue, 30 Apr 2013 02:55:34 UT

I'm compiling using VisualStudio 2012 for x64.
It compiled OK for the most part except for:
1>ClCompile:
1> crash_generation_app.cc
1>crash_generation_app.cc(365) : error C2065: 'GWL_HINSTANCE' : undeclared
identifier
HINSTANCE instance = (HINSTANCE)GetWindowLong(wnd, GWL_HINSTANCE);
According to the docs <[link]>GetWindowLong

minidump-2-core

bruce.daw...@gmail.com (Bruce Dawson) — Wed, 24 Apr 2013 00:24:52 UT

I'm trying to use minidump-2-core on some of the breakpad crash files from
our Linux builds and I'm not having much luck. gdb doesn't seem to like
them. The core file loads into gdb and it says a few encouraging things,
but mostly discouraging things:

No symbol table is loaded. Use the "file" command.

Dumping Breakpad Symbols From PDB

heartsb...@mindless.com (Jake Shadle) — Tue, 23 Apr 2013 14:02:32 UT

tl;dr PDB Dumping 1 hr -> 10 seconds
So I was really annoyed with how slow it took to create symbols from a
Microsoft PDB, using a ~500MB PDB it was taking up to an hour on my quite
beefy (32GB, 32CPU, SSD) machine at work. When I would break inside
randomly it was ALWAYS either doing an de/allocation for string data of

Missing some function and source file names.

jha...@gmail.com — Mon, 22 Apr 2013 23:01:59 UT

When we run mindump_stackwalk on our dump files the output is missing some
function and source file names for our modules. To throw a number out
there, say 50% of the function and source file names will show up for
module "x" but the rest will be missing and we just get an address (50% is
a bit arbitrary, it varies quite a bit).

google-breakpad fails to compile on OS X 10.8

c...@github.com (Corey Johnson) — Wed, 03 Apr 2013 16:29:57 UT

I've followed the directions
at [link]
but they google-brakepad fails to compile.
The first errors can be fixed by updating Breakpad.xcconfig to use "SDKROOT
= macosx10.8" and removing the GCC_VERSION vars. But then the gtestmockall

build breakpad using cygwin

huhang...@gmail.com (dot) — Mon, 01 Apr 2013 08:35:01 UT

Hi, guys, I've installed cygwin and copy whole directory of google-breadpad
to home/dot/.
But when I input "./configure & make" in cygwin, it stops and prints error
like this:
$ /home/dot/google-breakpad/conf igure: line 18: $'\r': command not found
/home/dot/google-breakpad/conf igure: line 33: syntax error near unexpected

How to use breakpad to analyse crash in shared objects

bvdhr...@gmail.com (Dhruva Bv) — Tue, 19 Mar 2013 01:06:37 UT

I used the example code as mentioned in the google breakpad sample and I
was able to figure out how to analyse crash dumps. But all I was able to do
was to find the location if it was in main executable. I am unable to
figure out if a crash happens in .so file although I am able to figure out
which shared object crashed I am unable to pinpoint location. Can somebody

crashes related to com.googlecode.google-breakpad

jarrett.stree...@gmail.com (Jarrett Streebin) — Thu, 07 Mar 2013 16:37:09 UT

Hi, I'm on a Mac Pro Retina and a few days ago one of my Steam games
stopped loading and the crash report suggested it was thread 15 (not sure
if those are random or now) and that com.googlecode.google-breakpad was to
blame. I've tried completely uninstalling Chrome and all google code I can
find but I can't get the error to stop. Any tips on fully removing google

linux-gate showing up twice on a call stack

I have a batch of Linux crashes where linux-gate.so is showing up twice on
the call stack. The top of the call stack looks like this:

non-optimized x86_64 dump_syms taking a long time

m...@thefoundry.co.uk (Mark Final) — Tue, 26 Feb 2013 15:23:43 UT

Hi all,

Granted, this is about running a non-optimized build of Breakpad, but
bear with me for the moment.

I do currently have debug builds of Breakpad tools running against
debug builds of our products (it's just the way it's been set up,
rather than a must have). I've seen on a number of Windows 7 build

x86 dump_syms on x64 ELF files?

bruce.daw...@gmail.com (Bruce Dawson) — Thu, 21 Feb 2013 19:28:14 UT

I'm hitting an assert when using our x86 Linux version of dump_syms on x64
Linux ELF files. Specifically FindSectionByName asserts because nsection ==
0, and nsection comes from elf_header->e_shnum where elf_header is a
pointer to Elf32_Shdr.

I couldn't find anywhere in the documentation where it explicitly states

OOP on Snow Leopard

m...@thefoundry.co.uk (Mark Final) — Thu, 21 Feb 2013 19:22:26 UT

Hi all,
Does anyone have Breakpad (latest SVN revision) working on OSX Snow Leopard
with an OOP crash server?
I realise Snow Leopard is getting on now, but it's something we were
testing today.
I'm just asking before I delve deeper.
Thanks,
Mark

I am trying the check google-breakpad<[link]>using MFC dialog based application. But I could not compile the project and

follow ?
