nyx-lib

Summary

Open webOS Platform Portability Layer

Description

Nyx is the platform portability layer used to isolate the remainder of Open webOS from dependencies on the hardware and core OS upon which it is running. It is implemented as a shared library that exposes a uniform client API and that expects to call into a series of platform-dependent modules that implement the API for a particular device.

This is the repository for nyx-lib, the shared library.

How to Build on Linux

Dependencies

Below are the tools and libraries (and their minimum versions) required to build nyx-lib:

  • cmake (version required by openwebos/cmake-modules-webos)
  • gcc 4.6.3
  • glib-2.0 2.32.1
  • make (any version)
  • openwebos/cmake-modules-webos 1.0.0 RC5
  • pkg-config 0.26

Building

Once you have downloaded the source, enter the following to build it (after changing into the directory under which it was downloaded):

$ mkdir BUILD
$ cd BUILD
$ cmake ..
$ make
$ sudo make install

The directory under which the files are installed defaults to /usr/local/webos. You can install them elsewhere by supplying a value for WEBOS_INSTALL_ROOT when invoking cmake. For example:

$ cmake -D WEBOS_INSTALL_ROOT:PATH=$HOME/projects/openwebos ..
$ make
$ make install

will install the files in subdirectories of $HOME/projects/openwebos.

Specifying WEBOS_INSTALL_ROOT also causes pkg-config to look in that tree first before searching the standard locations. You can specify additional directories to be searched prior to this one by setting the PKG_CONFIG_PATH environment variable.

If not specified, WEBOS_INSTALL_ROOT defaults to /usr/local/webos.

To configure for a debug build, enter:

$ cmake -D CMAKE_BUILD_TYPE:STRING=Debug ..

To see a list of the make targets that cmake has generated, enter:

$ make help

You may also specify the values for NYX_MODULE_DIR and NYX_MODULE_MOCK_DIR from command line. For example:

$ cmake -D NYX_MODULE_DIR:PATH=$HOME/nyx/modules ..
$ make
$ sudo make install

The default settings are extracted from the variables nyx_module_dirand nyx_module_mock_dir in nyx.pc.

Uninstalling

From the directory where you originally ran make install, enter:

$ [sudo] make uninstall

You will need to use sudo if you did not specify WEBOS_INSTALL_ROOT.

Generating Documentation

Nyx generates two sets of documentation, reflecting that fact that the APIs it presents to application and module writers are different.

The tools required to generate the documentation are:

  • doxygen 1.7.6.1
  • graphviz 2.26.3

Once you have run cmake, enter the following to generate the documentation:

$ make docs

To view the generated HTML documentation, point your browser to either of the following

Documentation/nyx/module_api/html/index.html
Documentation/nyx/client_api/html/index.html

in your build directory.

To install the generated documentation, enter:

$ [sudo] make install-docs

The documentation will be installed to usr/share/doc/nyx/module_api/htmland usr/share/doc/nyx/client_api/html under the tree defined by the value of WEBOS_INSTALL_ROOT (or its default).

You will need to use sudo if you did not specify WEBOS_INSTALL_ROOT.
