Datalayer: Assertion during when create Client

[MAE]

I had tried to use the sample for datalayer in the sdk. I was able to connect to virtual core and do some stuff. After that i want to use it in my own application.

But it didn't work: I get the Assertion, shown in the picture below. I try it on the same virtual machine, connected to the same virtual core with the same connection string.

When i try in the meantime to connect with the adapted datalayer example it works. But not with my aplication.

Call of CreateClient

Has Anybody an idea or Solution?

I had stripped down my program to few files.

Steps to reproduction:
1.) Copy file in your ubuntu and extract it and go to folder
2.) Adjust location of sdk in ./CMake/CntrlX/CMakeLists.txt (line 11: "set (BASE_DIR_SDK ~/com.boschrexroth.sdk.control-1.4.2/public)")
3.) cd CMake
4.) mkdir build
5.) cd build
6.) cmake ..
7.) make
8.) cd CntrlX
9.) export LD_LIBRARY_PATH=/home/dev/com.boschrexroth.sdk.control-1.4.2/public/bin/zmq/linux-gcc-x64/release:/home/dev/com.boschrexroth.sdk.control-1.4.2/public/bin/comm.datalayer/linux-gcc-x64/release       (!!! when neccessary adjust path)
10.) ./gcode_cntrlx
11.) you got the error

Output:
* find out which device file has to be used
ERROR: no file /sys/class/uio/uio0/name found

Sometimes it's so easy....

The variable "comm::datalayer::DatalayerSystem datalayer" must be alive the whole time. Not only in context of method.

Create a member in the class and it works.
