Overview
For Linux crash reporting, BugSplat recommends using Crashpad. Crashpad is the latest open source crash reporting tool built by Google and is the successor to the popular Breakpad crash reporter and allows you to submit minidumps to a configured URL after a crash occurs in your product.
Before continuing with the tutorial please review our myUbuntuCrasher sample application
Tutorial
The first step in integrating with Crashpad is to ensure that your system has all the required dependencies. These dependenices include git, python, llvm and clang++. The following snippet will download and install all the dependencies on an Ubuntu system:
1
sudo apt-get install git
2
sudo apt-get install python
3
sudo apt-get install llvm
4
sudo apt-get install clang

Next, you will need to build and integrate Crashpad with your application. For a step by step guide on how to build and integrate Crashpad please see this doc.
Once you've built and integrated Crashpad you will need to ensure that your application is built with symbolic information and a build identifier. Symbolic information is required in order to map the stacktrace in the minidump to function names and line numbers in your application's source. A build identifier is required so that minidump_stackwalk can match modules loaded at runtime with the corresponding .sym file.
When specifying the Crashpad libraries libbase.a must be the last library argument specified otherwise your code will not compile.
If you are building with clang++, specify the -g flag to ensure the output executable contains symbolic information for debugging. Additionally when building with clang++ you must pass the -Wl,--build-id argument in order to ensure the linker creates a build identifier in the output executable. The following script from myUbuntuCrasher demonstrates how to link the Crashpad libraries and output an executable with symbolic information using clang++:
1
#!/bin/bash
2
source exports.sh
3
​
4
clang++ -pthread $PROJECT_DIR/main.cpp \
5
  $CRASHPAD_DIR/lib/libclient.a \
6
  $CRASHPAD_DIR/lib/libutil.a \
7
  $CRASHPAD_DIR/lib/libbase.a \
8
  -I$CRASHPAD_DIR/include \
9
  -I$CRASHPAD_DIR/include/third_party/mini_chromium/mini_chromium \
10
  -o$OUT_DIR/$MODULE_NAME \
11
  -g \
12
  -Wl,--build-id

Finally, you will need to use the Breakpad tools dump_syms and symupload in order to generate and upload .sym files to BugSplat. Instructions on how to build these tools can be found here.
Once you've built dump_syms and symupload the following script will generate symbols and upload them to BugSplat:
1
#!/bin/bash
2
source exports.sh
3
​
4
export SYM_FILE=$OUT_DIR/$MODULE_NAME.sym
5
​
6
$CRASHPAD_DIR/tools/dump_syms $PROJECT_DIR/out/$MODULE_NAME > $SYM_FILE
7
$CRASHPAD_DIR/tools/symupload $SYM_FILE "https://$BUGSPLAT_DATABASE.bugsplat.com/post/bp/symbol/breakpadsymbols.php?appName=$BUGSPLAT_APP_NAME&appVer=$BUGSPLAT_APP_VERSION"
Copied!
It's important that you re-upload symbols each time you build your application otherwise BugSplat will not be able to generate function names and line numbers for the crash report. Symbols should be uploaded using a new version for every build to ensure that your crashes are processed quickly.
If you've set everything up correctly, your crash report should look like this:
