HelloWorldExampleTCP example build failed on ARM64 platform

[shdx2046]

Is there an already existing issue for this?

• I have searched the existing issues

Expected behavior

The HelloWorldExampleTCP demo can be built on x86 machine. It should also be built successfully on ARM64 platform.

Current behavior

When building on it locally on ARM64 platform (gcc version is 7.5.0 in my case), I got the error "reference to 'option' is ambiguous" .

Steps to reproduce

Pull the latest Fast DDS repo.
Build the demos with below commands in a newly created build folder in the examples/cpp/dds path.

cmake ..
cmake --build .

Fast DDS version/commit

2.8.1

Platform/Architecture

Other. Please specify in Additional context section.

Transport layer

TCPv4

Additional context

Ubuntu 18.04 ARM64
GCC version: 7.5.0

The build error can be resolved by replacing line 30 "namespace option = eprosima::option;" with "using namespace eprosima;"

Hi @shdx2046,

According to our CONTRIBUTING.md guidelines, Ubuntu 18.04 with gcc 7.5.0 is not an officially supported platform, so I am moving this issue to the proper discussion forum.
