HOw to add a vdr - plugin to LE build?

Hi there - i am currently playing around with LE 8.0 build-system.
I'd like to add a certain plugin for vdr to the distribution/image - how is that being done?
Or how can i manage to crosscompile the plugin for that specific Architecture?

I'd like to push this - i would like to get vdr-plugin-epg2vdr running on my LE 8 on Wetek.

How can i achieve that?

Build-Environment is available

Hi - i don't have it yet - but i am on my way - even if i continue my investigation - would be nice if some one (re)points me just in case i am wrong.

Here is what i did so far:
in packages/addons/addon-depends/vdr-plugins i created a folder vdr-plugin-epg2vdr that contains
a package.mk:

When issuing "scripts/build vdr-plugin-epg2vdr" this gets the current(latest) plugin-source (Tagged ones have gone yesterday ) and starts trying to compile it.

I needed to patch the source a little bit - some includes were not located well (uuid, zlib)
I also needed to create packages for libarchive and jansson (required by the plugin)

Currently linking fails with:

i have no clue what to do with the lto_wrapper stuff and i don't understand why he does not find python

I'd like to push that again - any ideas about the lto-wrapper?

You don't need the mysql-server to run on the box itself - my use case would be a wetek play 2 with vdr and epg2vdr on it, and the mysql-daemon is running on my backend-server (nas)

Build - dir was freshly checked out two days ago and the vanilla image built fine.

if you think it helps, i will setup a fresh vm for that and try again For compatibility reasons i need to stick to Krypton atm

Quote from CvH

then you are at the wrong branch, current Krypton is 8.2

As stated in wiki i did:

git clone https://github.com/LibreELEC/LibreELEC.tv.git

and 

git checkout 8.2.3

...

Anyway - i jut setup a plain VM and am currently building the image (Master) - after that i will try again with the additional packages

Sure - still building the image - i ran out of space and had to reconfigure the mount (nfs-share) - i will report

Ok - back again - what i did:

- cloned the git - as described here

pre-downloaded the tools

PROJECT=Generic ARCH=x86_64 tools/download-tool

started (and finished) building an initial (vanilla) image

PROJECT=Generic ARCH=x86_64 make image

works fine upt to here.

i then added jansson.mk as a package - it is required for epg2vdr

xxxx@libreelec:/develop/http://LibreELEC.tv/packages/addons/addon-depends$ ls -l jansson/

insgesamt 4

-rw-rw-r-- 1 xxxx xxxx 1428 Mär 6 2017 package.mk

jansson-package.txt

that builds fine with :

xxxx@libreelec:/develop/LibreELEC.tv$ PROJECT=Generic ARCH=x86_64 scripts/build jansson

i then created a package for epg2vdr:

xxxx@libreelec:/develop/LibreELEC.tv/packages/addons/addon-depends/vdr-plugins/vdr-plugin-epg2vdr$ ls -linsgesamt 4-rw-rw-r-- 1 xxxx xxxx 2003 Mär  7  2017 package.mk

epg2vdr-package.txt

the build fails with:

xxxx@libreelec:/develop/LibreELEC.tv$ PROJECT=Generic ARCH=x86_64 scripts/build vdr-plugin-epg2vdr

It seems python is "missing" - but i would assume that the build-instructions for epg2vdr need to be tweaked to match a cross-compiling - environment?

whoops - that was quick - but unfortunately the version of epg2vdr you took needs tinyxml2 - Version2 - that fails with the packages included LE (Version 1 only!?!)

I am around the python-stuff though - the Makefiles for epg2vdr need to be tweaked to use pkg-config. i recognized that in some directories of packages there are also patches - are those patches applied automatically or how does that work? For the time beeing i would need to patch the epg2vdr-plugin's Makefile to compile .... -

right now i am cleaning up everything and start the initial build from scratch - i ended put with the lto - errors ....

Hi again - as stated above - i started over (cleaned everything), took a snapshot of the VM, then tried to build the the package again.

I am currently trying to get 1.1.91 to be build (just for the records) - so your two commits.

Here is what happens:

lutz@libreelec:/develop/LibreELEC.tv$ PROJECT=Generic ARCH=x86_64 scripts/build vdr-plugin-epg2vdr
BUILD    vdr-plugin-epg2vdr (target)
TOOLCHAIN    make (auto-detect)

Compile xml ...

xml.c:53:13: error: 'class tinyxml2::XMLElement' has no member named 'SetText'
element->SetText(value);
^
xml.c: In member function 'tinyxml2::XMLNode* cXml::appendElement(const char*, int, tinyxml2::XMLNode*)':
xml.c:64:13: error: 'class tinyxml2::XMLElement' has no member named 'SetText'
element->SetText(value);
^
make[1]: *** [Makefile:87: xml.o] Error 1
make: *** [Makefile:117: hlib] Error 2
lutz@libreelec:/develop/LibreELEC.tv$

The error "has no member named 'SetText' ... indicates that it uses Old- Version of tinyxml2 - see here for example.

I found that under packages/textproc there are two tinyxml's - neither seems suitable to me - what to do?

Quote from Schreibwaise

Yes, those patches get applied automagically when the package is being built. The patch file name needs to obey to some naming scheme, however: It needs to start with the name of the package and needs to end with ".patch". And the patch needs to apply with "-p1". Just have a look at patches of some other package to get the idea.

Unfortunately I cannot help with your other issues; but I'm following this thread as I'm a VDR user myself. Thanks for working on this!

Works like charm - Thx

Patch #1 for fixing Makefile and lib/Makefile (python-config to be replaced by pkg-config ...) put under
