Hi Steven, I just realised that the patches are against v1.1.1, not the master branch. Let me know if it's not OK. I've some issues building v1.1.1. swig -Wall -python -noproxy ctracecmd.i parse-events.h:676: Error: Syntax error in input(3). Which is, probably, this 'bool' variable of type filter_arg_boolean struct filter_arg { enum filter_arg_type type; union { struct filter_arg_boolean bool; <<<< 676 struct filter_arg_field field; struct filter_arg_value value; struct filter_arg_op op; struct filter_arg_exp exp; struct filter_arg_num num; struct filter_arg_str str; }; }; Is this a known problem? -ss ^ permalink raw reply [flat|nested] 7+ messages in thread
