How to build accountsservice

How to build with debug symbols

First, get the source code for accountsservice:

mkdir accountsservice
cd accountsservice
apt-get source accountsservice
cd accountsservice-0.6.55/

To create a debug build:

DEB_BUILD_OPTIONS='nostrip noopt debug' debuild -b -uc -us

Install like this:

sudo dpkg -i ../*.deb

How to build with address sanitizer (ASAN)

The instructions that I found here don't work on accountsservice. (I get lots of linker errors like undefined reference to __asan_report_store8', presumably because libasanhasn't been included in the link step.) But I was able to successfully create an ASAN build by modifyingsrc/meson.build` like this:

diff --git a/src/meson.build b/src/meson.build

Then run the same commands as before to build and install:

sudo dpkg -i ../*.deb
