ok, my fault. i executed cmake manually before which led to this issue.

[hd789]

install kodi-platform, https://github.com/xbmc/kodi-platform.
you also have to execute the install target of kodi to get the cmake helpers and addon bindings installed.

The link didn't work because of an extra dot at the end. https://github.com/xbmc/kodi-platform

Helllo @wsnipex

I'm trying to adapt your below (quoted) instructions to my case, but am running into an error, most likely because the installation of Kodi that I compiled is installed to /opt/KODI.d (not in /usr or /usr/local).

Code:

cd /home/carel/src/kodi/kodi-platform
cmake -DCMAKE_INSTALL_PREFIX=/usr # or /usr/local, which is the default
make && sudo make install

cd /home/carel/src/kodi/pvr.vdr.vnsi
cmake -DCMAKE_INSTALL_PREFIX=/usr # must match kodis prefix
make && sudo make install

Here are my details:

Code:

/home/jdoe/KODI.d/xbmc-master/   # Source code for Kodi v15b2/Isengard.
/home/jdoe/KODI.d/kodi-platform-master  # Source code for the Kodi Platform
/home/jdoe/KODI.d/pvr.stalker  # Soure code for the pvr.stalker addon
/opt/KODI.d # The directory under which my compiled Kodi has been installed.

Here is the problem:

Code:

$ cd /home/jdoe/KODI.d/kodi-platform-master && cmake -DCMAKE_INSTALL_PREFIX=/opt/KODI.d

Code:

CMake Error at CMakeLists.txt:11 (find_package):
  By not providing "Findplatform.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "platform",
  but CMake did not find one.

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

    platformConfig.cmake
    platform-config.cmake

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

What adjustments to your instructions above (both parts) do I need to make for my case? I've tried a few things, but with no luck.

I thank you in advance!

as of lately OS platform specific stuff has been split out of kodi-platform into https://github.com/Pulse-Eight/platform
So, you need to install this lib first as well.

Ah, okay. Thank you!
Adding that extra step (which I pre-pended to your original instructions below), solved the issue.

Code:

cd /home/carel/src/kodi/platform-master # Obtained from here: https://github.com/Pulse-Eight/platform
cmake -DCMAKE_INSTALL_PREFIX=/usr # or /usr/local, which is the default
make && sudo make install

cd /home/carel/src/kodi/kodi-platform
cmake -DCMAKE_INSTALL_PREFIX=/usr # or /usr/local, which is the default
make && sudo make install

cd /home/carel/src/kodi/pvr.vdr.vnsi
cmake -DCMAKE_INSTALL_PREFIX=/usr # must match kodis prefix
make && sudo make install

You're always very helpful @wsnipex, and I appreciate it. Thank you.

I'm having a problem with the platform library. It used to build fine using the command:

Code:

cmake -DCMAKE_BUILD_TYPE=Debug \
      -DCMAKE_INSTALL_PREFIX=$HOME/kodi \
      ..

However, now CMake reports:

Code:

CMake Error at CMakeLists.txt:45 (install):
  install TARGETS given no ARCHIVE DESTINATION for static library target
  "platform".

I got platform to build using:

Code:

cmake -DCMAKE_BUILD_TYPE=Debug \
      -DCMAKE_INSTALL_PREFIX=$HOME/kodi \
      -DCMAKE_INSTALL_LIBDIR=$HOME/kodi/lib \
      -DCMAKE_INSTALL_LIBDIR_NOARCH=$HOME/kodi/lib \
      ..

But when I try to build kodi-platform, I get this error:

Code:

CMake Error at CMakeLists.txt:41 (message):
  -L/home/garrett/kodi//home/garrett/kodi/lib -lplatform;-lpthread

The problem is in the installed platform.pc pkgconfig file. it looks like

Code:

prefix=/home/garrett/kodi
libdir=/home/garrett/kodi//home/garrett/kodi/lib
includedir=/home/garrett/kodi/include
DEPENDENCIES=-lpthread

Name: platform
Description: Platform support library 1.0
Version: 1.0
Libs: -L${libdir} -lplatform
Cflags: -I${includedir}

Do i need to use a different CMake command, or is there a problem figuring out the lib directory?

[wsnipex]

I just commited the fix to platform: https://github.com/Pulse-Eight/platform/...6911c80580

[garbear]

you rock. still seeing the same cmake error with kodi-platform (although with a correct path now):

Code:

CMake Error at CMakeLists.txt:41 (message):
  -L/home/garrett/kodi/lib -lplatform;-lpthread

[nyceyes]

The issue-11 'Platform' fix that @wsnipex just fixed (btw, I created that now-resolved issue), seems different than your still lingering 'kodi-platform' issue.

I'm of course interested in this, too (for my Fedora based compiles of stalker pvr).

[wsnipex]

garbear, can you provide full output? Did you clean kodi-platform after the libplatform fix?

[ironic_monkey]

mixing lists and strings somewhere.

sorry, traveling over the weekend. here's the cmake output

this is again something stupid with libplatform. Like notspiff said, its mixing lists and strings:
in lib/platform/platform-config.cmake:

Code:

else(WIN32)
  set (platform_LIBRARY "-L/usr/lib/x86_64-linux-gnu -lplatform")
endif(WIN32)
set (platform_LIBRARIES ${platform_LIBRARY} "-lpthread")

try to change it to:

Code:

else(WIN32)
  set (platform_LIBRARY "-L/usr/lib/x86_64-linux-gnu -lplatform")
endif(WIN32)
set (platform_LIBRARIES "${platform_LIBRARY} -lpthread")

[garbear]

good news! i made the change, ran cmake again, and got this output:

Code:

CMake Error at CMakeLists.txt:41 (message):
  -L/home/garrett/kodi/lib -lplatform -lpthread

Hm... that looks right, yea? So the error must be caused by something else. I deleted everything and started fresh - kodi, platform, kodi-platform, all the add-ons, and the entire cmake install prefix

Now things are working correctly, even without your change applied. Something must have been stale (or possibly I forgot a git pull --rebase was was using a really old repo) as kodi-platform builds and installs now. thanks again!

doh
some issues simply solves themselves
