No logs to be posted in the forum please. Post at a public Pastebin type site and then provide the link back here.

Maybe provide a bit more information on what your question is. Detail the steps you have already taken that led you to that point.

[AlirezaTorabi]

OK cool.

So %100 as in "[100%] Linking CXX executable kodi.bin" compile and then linking fails to build "kodi.bin" and I've a feeling this is to do with GCC and STL and/or static library linking...

I'm following: https://github.com/xbmc/xbmc/blob/master...ADME.linux

So as the stock gcc on CentOS is "gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11)" I've manually added:
"gcc (GCC) 7.1.0" &

The main issue I think is these two static libraries:

-- Found TinyXML: /usr/local/lib/libtinyxml.a (found version "2.6.2")
-- Found TagLib: /usr/local/lib/libtag.a (found version "1.11.1")

During linking.
I've tried to have them both between -Wl,--whole-archive ... -Wl,--no-whole-archive
with no joy...

[wsnipex]

tinyxml seems to be the problem indeed.
can you try with the exact same version we use on our build servers?
http://mirrors.kodi.tv/build-deps/source...2_2.tar.gz

If that doesn't help, a try would be to turn off the gold linker: -DENABLE_LDGOLD=OFF

edit: and your libpcre version might need an update as well

[AlirezaTorabi]

Success:
[100%] Built target kodi
gmake[1]: Leaving directory `/home/alireza/xbmc/kodi.build'

This "TinyXML" works. Still being detected as:
-- Found TinyXML: /usr/local/lib/libtinyxml.a (found version "2.6.2")

I'm able to link with the default "ld.gold".

Sure I needed to update libpcre as well:
-- Found PCRE: /usr/local/lib/libpcrecpp.so (found version "8.41")

@wsnipex Thanks!
