What tree/branch is this developed against? I'm getting the following with Linus' latest and tip tree: builtin-c2c.c: In function ‘perf_c2c__process_sample’: builtin-c2c.c:68:20: error: request for member ‘func’ in something not a structure or union builtin-c2c.c:69:36: error: request for member ‘func’ in something not a structure or union builtin-c2c.c: In function ‘perf_c2c__read_events’: builtin-c2c.c:81:2: error: passing argument 1 of ‘perf_session__new’ from incompatible pointer type [-Werror] In file included from builtin-c2c.c:6:0: util/session.h:52:22: note: expected ‘struct perf_data_file *’ but argument is of type ‘const char *’ builtin-c2c.c:81:2: error: too many arguments to function ‘perf_session__new’ In file included from builtin-c2c.c:6:0: util/session.h:52:22: note: declared here -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
