pebble sdk - error: expected identifier before '_Bool' -

-

i had following code when dealing sync tuple:

static void sync_tuple_changed_callback(const uint32_t key, const tuple* new_tuple, const tuple* old_tuple, void* context) {   persist_write_bool(key,new_tuple->value->bool); }

however, tried building (in cloud pebble), , got error:

../src/main.c: in function 'sync_tuple_changed_callback': ../src/main.c:25:44: error: expected identifier before '_bool'

what's going on?

there no bool member of value union - best bet use uint8 member instead, passing 1 true , 0 false:

static void sync_tuple_changed_callback(const uint32_t key, const tuple* new_tuple, const tuple* old_tuple, void* context) {   persist_write_bool(key,new_tuple->value->uint8 != 0); }

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
