watchping

Description

Building from sources

git clone https://github.com/jbwong05/watchping.git
cd watchping
mkdir build
cd build
cmake ..
make

The CMAKE_BUILD_TYPE variable can also be set to Debug using -DCMAKE_BUILD_TYPE=Debug if a debug version is required.

Installation

git clone https://github.com/jbwong05/watchping.git
cd watchping
mkdir build
cd build
cmake ..
make
sudo make install

By default the install path is set to /usr/local/bin. This can be changed by setting the CMAKE_INSTALL_PREFIX using -DCMAKE_INSTALL_PREFIX=<dir> if another directory is preferred.

Uninstallation

sudo make uninstall
