The hello world service and test do not run.

After building a fresh image with bitbake agl-demo-platform-crosssdk, installing the sdk and sourcing the sdk environment file, here are the following steps taken 

git clone https://github.com/iotbzh/helloworld-service.git helloworld_gg
cd helloworld_gg
mkdir build
cd build
cmake  -DBUILD_TEST_WGT=TRUE ..
make
make widget

It should be noted that there are discrepancies within the documentation - for example

http://docs.automotivelinux.org/guppy/docs/apis_services/en/dev/reference/afb-test/the-test-widget.html#build-the-test-widget

The example shown uses -DBUILD_TEST_WIDGET=TRUE, however the correct option is the one shown in the description above -DBUILD_TEST_WGT=TRUE, which would not produce a test widget file following the former example.

This produces 2 .wgt files

scp agl-service-helloworld*.wgt root@up2.lan:~

The result of the installation and running the helloworld service is the following:

intel-corei7-64:~# afm-util install agl-service-helloworld.wgt 
{
  "added":"agl-service-helloworld@1.0-aa001d2"
}
intel-corei7-64:~# afm-util start agl-service-helloworld@1.0-aa001d2
ERROR:  cannot-start

This results in the following helloservice.log

It turns out that the generated systemd service points to a non-existent .so file, and therefore this has to be fixed by editing the conf.d/wgt/config.xml.in line13 (found by sbogdanov):

<param name="lib/afb-helloworld.so" value="local" />

into 

<param name="lib/afb-helloworld-skeleton.so" value="local" />

 After cleaning and rebuilding the hello world service widget, scp-ing to the board and installing, the service seems to be running:

intel-corei7-64:~# afm-util install agl-service-helloworld.wgt 
{ 
  "added":"agl-service-helloworld@1.0-aa001d2-dirty" 
} 
intel-corei7-64:~# afm-util start agl-service-helloworld@1.0-aa001d2-dirty 
2181 
intel-corei7-64:~#

Installing the test widget seems to go fine, however running it - does not:

intel-corei7-64:~# afm-util install agl-service-helloworld-test.wgt 
{
 "added":"agl-service-helloworld-test@1.0-aa001d2-dirty"
}
intel-corei7-64:~# afm-util start agl-service-helloworld-test@1.0-aa001d2-dirty
ERROR: cannot-start

The failing test service reports this log: hellosvc_test.log
