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.
