Libusermetrics is a project on Launchpad (https://launchpad.net/libusermetrics). To grab a copy use the command:
$ bzr branch lp:libusermetrics
To succesfully build libusermetrics there are a few packages required. The easiest way to get them is to use the packaging build dependencies:
$ sudo apt-get install devscripts equivs cmake
$ sudo mk-build-deps --install --tool "apt-get -y" --build-dep debian/control
Libusermetrics is built using cmake. To make life simpler, you can use the included wrapper script:
$ ./build
This will run cmake in the directory
../${BRANCH_NAME}-build
You can also ask it to create an Eclipse project as follows:
$ ./build -e
The next step is to build the source and run the tests:
$ cd ../libusermetrics-build/make (-j8)
$ make check
To install libusermetrics just use the normal make install command:
$ make install
This will install the libusermetrics input / output libraries, storage service, and header files to the configured installation location (/usr/local by default). If you install to a non-standard location, keep in mind that you will probably need to properly set the PKG_CONFIG_PATH environment variable to allow other applications to build against libusermetrics, and LD_LIBRARY_PATH to allow applications to find the libusermetrics libraries at runtime.
