It defines a minimal yet extensible +C API for plugin code and a format for plugin "bundles". See +<http://lv2plug.in> for more information. + +This package contains specifications (C headers and Turtle files), +documentation generation tools, and example plugins. + +Building and installation requires only Python 2.6. Building the documentation +requires Doxygen. + + +Installation +------------ + +A typical build looks something like this: + + ./waf configure --prefix=/foo + ./waf + sudo ./waf install + +or, for packaging: + + DESTDIR=/home/packager/lv2root ./waf install + +For help on the other available options, run: + + ./waf --help + +The bundle installation directory can be set with the --lv2dir option, e.g.: + + ./waf configure --lv2dir=/foo/lib/lv2 + +Configuring with `--lv2-user` will install bundles to the user-local location. + + +Packaging +--------- + +Specification bundles are both a build-time and run-time dependency of programs +that use LV2. Programs expect their data to be available somewhere in +`LV2_PATH`. + +See <http://lv2plug.in/pages/filesystem-hierarchy-standard.html> for details on +the standard installation paths. + +Do not split up LV2 bundles, they are self-contained and must remain whole. +Other than that, things may be split to suit distribution needs. For example, +separate packages for specifications, tools, and plugins, may be good idea. + + +Header Installation +------------------- + +By default symbolic links to headers in bundles are installed to `INCLUDEDIR`. +If symbolic links are a problem, configure with `--copy-headers` and copies +will be installed instead. + +Headers are installed in two paths, the universal URI-based style: + + #include "lv2/lv2plug.in/ns/ext/urid/urid.h" + +and the newer simple core style: + + #include "lv2/urid/urid.h" + +Projects are encouraged to migrate to the latter style, though note that this +style of include path may only be used by official LV2 specifications. + + +Documentation +------------- + +Configuring with the --docs option will build the documentation for all the +included specifications if Doxygen is available. For example: + + ./waf configure --docs + ./waf + +Specification documentation is also availabe online at <http://lv2plug.in/ns>. |
