BuildFailed Error: Cannot build C++ SDK Helloworld with qibuild - c++

Question

I'm trying to install NaoQI C++ SDK on Linux 18.04.1 (VirtualBox). I followed this installation instruction: http://doc.aldebaran.com/2-1/dev/cpp/install_guide.html
My problem is in Part E. Step.3, when I'm trying to run "qibuild make"
I get this error while I'm trying to build the helloworld example:
CMakeFiles/testhelloworld.dir/testhelloworld.cpp.o: In function

Please, help me if you have any idea about what the problem is. Thank you!

Answer 1

I had the same problem with Fedora 29... After some hours of search I found that adding set(CMAKE_CXX_FLAGS "-D_GLIBCXX_USE_CXX11_ABI=0") to the CMakeLists.txt file fixed the problem.
I found the solution here:
gcc using c++11 standard even though 98 explicitly specified

Answer 2

Most probably you have an ABI incompatibility issue, due to the transition to C++11. You are using Ubuntu 18.04, which compilers are configured to link with modern C++ libraries, but the toolchain is compiled with former ABIs, and does not enforce compiler flags to ensure compatibility.
To workaround this, either:
Set compiler flags to make sure you don't link against C++11 libraries (if someone knows them, please share).
Compile for the robot instead of your machine, by using the cross-toolchain instead of the Linux toolchain.
Use Ubuntu 12.04, as told in the installation guide.
By the way, in the C++ installation guide, subsection E.4, it says to compile the example under core/sayhelloworld. Here you compiled the example under core/helloworld.
