Hi,
i don't know if this is the appropriate place to ask this, but i did
not see any mailing list/forum/irc channel or similar thing on the
protobuf-c project page so i thought i'd ask here. I realize that this
is a very long email, so i am extra grateful to anyone who actually
reads it. I am currently having problems with protobuf-c. When i
serialize the message structs that i created, some parts of them are
left out. case in point:
### BEGIN CODE ###
message Point {
repeated double parameters = 1;
optional Error error = 2;
}
message GaioQuery {
repeated Point points = 1;
}
message Message {
required int32 dialog_id = 1;
optional GaioQuery gaio_query = 2;
[...] (left out some stuff here)
optional Error error = 10;
}
### END CODE ###
Here, i created a GaioQuery containing 47 points each containing 5
parameters using the methods given by the protobuf-c message. I
confirmed with gdb that the values are present and correct right before
packing them into the byte buffer. On the other side, however, the
message looks like this:
dialog_id: 0
gaio_query {
points {
}
[repeats 46 times]
}
So, the parameters are not transmitted. I inspected the compilation logs
for protobuf-c and came up with the following errors:
### start configure log ###
[...]
configure: WARNING: google/protobuf/stubs/common.h: accepted by the
compiler, rejected by the preprocessor!
configure: WARNING: google/protobuf/stubs/common.h: proceeding with the
compiler's result

### end configure log ###
### start make log ###

So it appears that the protobuf-c self tests do not work and thus i
suspect the error in my program is a result of protobuf-c not working. I
have no idea why it does not work though and would really appreciate any
help with this.
Hope i did not bore you too much
