[ltt-dev] compiling tracepoints in UST

[sylvain.geneves@inrialpes.fr (Sylvain Geneves)]

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
