unable to make gkk on RPi w. Stretch and bluez 5.50

[krimp]

I have all the latest (as pr 15-nov-2018) dis-upgrades and updates on an RPi3 w. Stretch and have installed Bluez-5.50. The make of gkk gives the output shown below.
Any help would be appreciated.

Is this a build of the code straight from GitHub, or has it been modified in any way?

The errors don't add up. I'm seeing an error in which ggk::registerObjects() is unable to find ggk::DBusObject::generateIntrospectionXML, but earlier in the log it says ggk::DBusObject::generateIntrospectionXML is unable to find a Logger. So clearly that introspection method it is present.

This tells me it's a bit deeper than what it appears. A clue is that one of those mentions of generateIntrospectionXML are actually:

ggk::DBusObject::generateIntrospectionXML(int)
and
ggk::DBusObject::generateIntrospectionXML[abi:cxx11](int)

To the compiler, those are two different functions. I'd never seen that [abi:cxx11] mangling before, so I did some digging which led to GCC's dual ABI support in gcc 5.1. From what I understand, this shouldn't impact you since you're building the library and the application with the same version of gcc. However, this sentence struck a note:

This discovered an issue when building software using the new C++ ABI with clang, which builds against the new ABI (as instructed in the GCC header file), but does not know about the abi_tag attribute. This results in problems such as (for example) any function in a library with a std::string return type will be mangled with a [abi:cxx11] ABI tag.

...which looks like a very good description of the problem you're seeing. Are you somehow mixing gcc/clang on your installation? Possibly with symlinks in /usr/bin (...or something?)

I'm grasping because I can't reproduce it locally.

No modifications done to the code or mix with clang that I'm aware of . Initially I had Jessie on the RPi3, but was not able to compile gkk with glib 2.19 (make complained about the g_auto()). Seeing that other had succeeded using gkk on Stretch, I upgraded from Jessie to Stretch (and got glib 2.24 iirc ). Could it be that my issues are related to the upgrade from Jessie to Stretch?

JFYI, I compiled the latest version successfully on a Raspberry Pi v3, with CentOS 7 Linux and Bluez 5.50.

The problem with this version is that I get the error ERROR: Unsupported response event type: 0x0011 (Authentication failed event), and then it loses the connection. This happens only with iOS devices, not with Android.

I've not opened an issue because I've already one open and don't want to stress our developer! 😃

So, that's the reason I'm still using the 5.43 which works pretty well, except for the error in #9.

You might try having it compile with clang instead of gcc. Try:

export CC=/usr/bin/clang
export CXX=/usr/bin/clang++
make distclean
./configure && make

If this works, it's not a solution, but a workaround.

I'm unable to test this, not having access to that development environment any longer (which is why I've been slow/unable to respond to issues, hoping folks will help each other out.)

Did a recap: Initially I cloned the gkk git when I had Jessie on the RPi. Got some issues with the m4, and "google" adviced me to run autoreconf -f -i. Then I was able to do the make, but stumbled into the g_auto() issue. Then upgraded to Stretch...

Your comment regading the symlink made me think that maybe the autoreconf did something with some files in gobbledegook .

Today I deleted completely the gobbledegook directory and did a fresh clone. Now everything works as it should.

Thank you very much for your help, and for an amacing library package.

Glad you got it working.
