Compilation Error with RTT_CLI

[ran]

Hi, 

I'm trying to add RTT_CLI to my application  : 

//enable rtt cli
NRF_CLI_RTT_DEF(m_cli_rtt_transport);
NRF_CLI_DEF(m_cli_rtt,"rtt_cli:~$ ",&m_cli_rtt_transport.transport,'\n',CLI_EXAMPLE_LOG_QUEUE_SIZE);
ret_code_t ret = nrf_cli_init(&m_cli_rtt, NULL, true, true, NRF_LOG_SEVERITY_INFO);
APP_ERROR_CHECK(ret);

When compile, I'm getting : 

Any Ideas ? 

[ran]

resolved by moving the define out of a function scope
