[lttng-dev] Issues compiling User Space Tracing examples from documentation

[John O'Sullivan]

Hi ,
I am trying to use some user space tracing, following the example shown here:
https://lttng.org/docs/v2.10/
In the section Trace a user application, I am using the sample provided
--------------------------
hello-tp.h

#undef TRACEPOINT_PROVIDER
#define TRACEPOINT_PROVIDER hello_world

#undef TRACEPOINT_INCLUDE
#define TRACEPOINT_INCLUDE "./hello-tp.h"

#if !defined(_HELLO_TP_H) || defined(TRACEPOINT_HEADER_MULTI_READ)
#define _HELLO_TP_H

#include <lttng/tracepoint.h>

TRACEPOINT_EVENT(
    hello_world,
    my_first_tracepoint,
    TP_ARGS(
        int, my_integer_arg,
        char*, my_string_arg
    ),
    TP_FIELDS(
        ctf_string(my_string_field, my_string_arg)
        ctf_integer(int, my_integer_field, my_integer_arg)
    )
)

#endif /* _HELLO_TP_H */

#include <lttng/tracepoint-event.h>
-------------------------


With
------------------------------
hello-tp.c

#define TRACEPOINT_CREATE_PROBES
#define TRACEPOINT_DEFINE

#include "hello-tp.h"
--------------------

As soon as I compile

gccarm -c -I <path to my includes>  hello-tp.c
In file included from hello-tp.h:27:0,
                 from hello-tp.c:4:
/...../usr/include/lttng/tracepoint-event.h:56:28: fatal error: ./hello-tp.h: No such file or directory
 #include TRACEPOINT_INCLUDE
                            ^
compilation terminated.

I am cross compiling for arm using a buildroot based environment.
Any suggestions?

regards

John O'Sullivan
