Develop PVR addons with new cmake build system
#61
yes, cause you should point it (cmake) to the game.libretro build system, not $HOME/workspace/xbmc/project/cmake/addons

I followed the OP. how can I point to the game.libretro build system? cmake .. doesn't work:

Code:
CMake Error at CMakeLists.txt:8 (find_package):
  By not providing "Findkodi.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "kodi", but
  CMake did not find one.

  Could not find a package configuration file provided by "kodi" with any of
  the following names:

    kodiConfig.cmake
    kodi-config.cmake

  Add the installation prefix of "kodi" to CMAKE_PREFIX_PATH or set
  "kodi_DIR" to a directory containing one of the above files.  If "kodi"
  provides a separate development package or SDK, be sure it has been
  installed.

also there's something wrong with -DCMAKE_INSTALL_PREFIX=$HOME/workspace/xbmc/addons

instead of

Code:
$ ls addons/
drwxrwxr-x 67 garrett garrett 4096 Mar 23 01:29 ./
drwxrwxr-x 17 garrett garrett 4096 Mar 22 21:09 ../
drwxrwxr-x  3 garrett garrett 4096 Mar  4 17:39 audioencoder.xbmc.builtin.aac/
drwxrwxr-x  3 garrett garrett 4096 Mar  4 17:39 audioencoder.xbmc.builtin.wma/
...
drwxrwxr-x  3 garrett garrett 4096 Mar 22 19:50 game.libretro/
drwxrwxr-x  3 garrett garrett 4096 Mar 22 19:50 game.libretro.nestopia/

i get

Code:
$ ls addons/
drwxrwxr-x 67 garrett garrett 4096 Mar 23 01:29 ./
drwxrwxr-x 17 garrett garrett 4096 Mar 22 21:09 ../
drwxrwxr-x  3 garrett garrett 4096 Mar  4 17:39 audioencoder.xbmc.builtin.aac/

...
drwxrwxr-x  3 garrett garrett 4096 Mar 22 19:50 lib/
drwxrwxr-x  3 garrett garrett 4096 Mar 22 19:50 share/

Code:
$ find addons/lib/

.. nothing wrong, everything is behaving as it should.

to do standalone builds you have to pre-supply the kodi bindings and cmake helpers. make install of kodi does this, so does sudo apt-get install kodi-xxx-dev if you use the ubuntu ppa. you also need to supply kodi-platform for most addons.

you get those lib and share directories cause you do not set PACKAGE_ZIP. that changes the install format from a normal linux install (which you are seeing) to a scheme suitable for zip files. you can do 'make addon-package' and you'll get the addon zipped and ready for install in addon browser (for sticking in a repo).

I'm trying to supply the kodi bindings to cmake

-DCMAKE_PREFIX_PATH=$HOME/kodi gives me the missing kodi-config.cmake error

-DCMAKE_PREFIX_PATH=$HOME/kodi/usr/local locates kodi-config.cmake but can't find kodiplatform-config.cmake

is there a second variable i need to provide kodi-platform or should I be pointing CMAKE_PREFIX_PATH somewhere other than the usr/lib folder of kodi's make install destination?

in standalone builds, everything behaves as "normal" software builds. the build system looks for its dependencies, by default with /usr and /usr/local prefixes.

in those prefixes you have to supply a 'make install' of kodi, and a 'make install' of kodi-platform, or provide the files through other means (e.g. apt-get).

if you do not want to stick them on your system/in those prefixes, you build and install kodi and kodi-platform with another prefix. e.g. $HOME/kodi and then supply that to the addon build system as a prefix.

it seems you haven't set the prefix for kodi, but rather the DESTDIR. you can use that if you want, but then you have to adjust the prefix path accordingly (in your case the prefix is $HOME/kodi/usr/local).

k, think I got it. can you check https://github.com/kodi-game/game.libret.../Readme.md section "Building stand-alone" real quick?

Out of interest, what are the benefits of the new build system? Will Kodi itself be moving to this cmake based build system as well?

Also on the windows platform, the previous projects included the post build event to copy the deliverables into the kodi addons folder (when project was part of kodi solution). The first post mentions to create the post build event ourselves, which is easy enough, but what about making the cmake generated visual studio projects include the post build events automatically, is that possible to do?

1) a single build system for all platforms
2) decoupled repositories
3) once everything is done, binary addons will be just like other addons
- hosted in a repo
- updateable completely on their own

yes, you can do that as a post-build step in the project. i do that in my fork

The build system is written for packaging/deployment and not for development. But on win32 you can simple change the path of CMAKE_INSTALL_PREFIX to the addons directory of your Kodi installation/development checkout and the addon directories will automatically be generated there.
Always read the online manual (wiki), FAQ (wiki) and search the forum before posting.
Do not e-mail Team Kodi members directly asking for support. Read/follow the forum rules (wiki).
Please read the pages on troubleshooting (wiki) and bug reporting (wiki) before reporting issues.

because my system is quite a bit different than upstream; all addons are built inline with the main build system since my fork is all cmake. they need to build equivalent functionality in their system.

Did you clone them addons in /home/leatherface/Compile/xbmc/pvr-addons? Doesnt look like it.

I cloned the new addons from kodi-pvr repository and have tried outside xbmc dir with same results.
