Hi,
I tried to use tracepoints with UST but i have a problem when it comes
to compile my code...
for a better understanding, i gave it a try with the tracepoint exemple
from the UST manual, replacing my_channel with ust and it gives the same
thing.
Here is the content of the problematic file :
1 #include <ust/tracepoint.h>
2
3 DECLARE_TRACE(ust_myevent, TPPROTO(int v, char *st), TPARGS(v, st));
Here is the error :
tp.h:3: error: expected ‘)’ before ‘(’ token
tp.h:3: error: expected ‘)’ before ‘(’ token
tp.h:3: error: expected ‘)’ before ‘(’ token
tp.h: In function ‘register_trace_ust_myevent’:
tp.h:3: error: ‘probe’ undeclared (first use in this function)
tp.h:3: error: (Each undeclared identifier is reported only once
tp.h:3: error: for each function it appears in.)
tp.h: At top level:
tp.h:3: error: expected ‘)’ before ‘(’ token
tp.h: In function ‘unregister_trace_ust_myevent’:
tp.h:3: error: ‘probe’ undeclared (first use in this function)
I've got some difficulties understanding the nested macros behind
DECLARE_TRACE, and i can't see why such an error is triggered, so if
anyone has a clue i'd really appreciate it.
I'm using the git version of UST, and here's my output of gcc --version:
gcc (Debian 4.4.4-1) 4.4.4
Thanks in advance
Regards
Sylvain
