samu: subcommand failed

There is a fix: In
clients/chromecast/libtizchromecast/src/tizchromecast.cpp, both appearances of
boost::bind (&tizchromecast::new_cast_status, this, _1, _2)); need to be changed to
boost::bind (&tizchromecast::new_cast_status, this, boost::placeholders::_1, boost::placeholders::_2));, see this patch.

Steps to Reproduce

Build tizonia on Arch Linux from this recipe from the latest git clone with

CFLAGS='-O2 -s -DNDEBUG' \
CXXFLAGS='-O2 -s -DNDEBUG -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security' \
export SAMUFLAGS=-j1
arch-meson tizonia-all-git build
samu -v -C build

Expected behavior:

Succeeding build.

Actual behaviour:

Failing build with above error.

Reproduces how often:

Each time.

Versions

Current git.

Installation Method Used

Trying to build from source.
