Using Arch ARM, I am unable to build 17.4 due to the following error near the very end of the build (shown below). I have been building kodi on the RPi2 like this since version 17 without problems... I am even able to build 17.4rc1 without issue. It is just 17.4 (final) that causes this problem.

Note that I rebuilt the system's libcrossguid with the -fPIC switch before I starting the kodi build, but it still errors out as shown. Am I misinterpreting the error? Is the error telling me I need to add -fPIC to my CFLAGS/CXXFLAGS when building kodi not libcrossguid?

Thanks for any insights.

Code:

_CPU=cortex-a7
cmake -DCMAKE_INSTALL_PREFIX=/usr \
    -DCMAKE_INSTALL_LIBDIR=/usr/lib \
    -DCMAKE_PREFIX_PATH=/opt/vc \
    -DCORE_SYSTEM_NAME=rbpi \
    -DWITH_CPU="$_CPU" \
    -DENABLE_EVENTCLIENTS=ON \
    -DENABLE_OPENGL=OFF \
    -DENABLE_X11=OFF \
    -DENABLE_VAAPI=OFF \
    -DENABLE_VDPAU=OFF \
    -DLIRC_DEVICE=/run/lirc/lircd \
    ../"xbmc-$pkgver-$_codename"/project/cmake

  make && make preinstall

Ah, I see now the error means that the kodi build itself requires the -fPIC switch (successfully built it without modifying the system's libcrossguid package... what changed between 17.4rc1 and 17.4 (final) that requires -fPIC and is it expected?

Not sure what that error is about, but for Raspbian, I do not compile/make a separate package for libcrossguid anymore, I use this cmake flag to build it, it works for 17.4 final:
-DENABLE_INTERNAL_CROSSGUID=ON

See if that works for you.

@rascas - I get the same error strangely with your switch and without the libcross package installed:

Code:

...

Which gcc version are you using ? If 7.X it might be the problem, but I am not an expert on that so I am afraid I can help you much more.

[graysky]

Yes, Arch ARM uses a pretty packages including gcc (currently 7.1.1 I believe).

Delete the build dir before rebuilding. It seems to have found a previously compiled version of that lib, so it won't be compiling it again.

I did but it is still there suggesting it's getting build by the package. The solution for building with the internal version is to add -fPIC to the CFLAGS and CXXFLAGS before building:

Code:

CFLAGS+=" -fPIC"
CXXFLAGS+=" -fPIC"

Now I can remove the dependency of the external libcrossguid altogether. Thank you for the suggestion.
