Error when deserializing message, buffer overrun, publisher in labview, subscriber in ubuntu machine.

edit

Hello,

I have the following setup. There are two machines, one arm device with Ubuntu in which I run the ros master and a subscriber, and one labview system which connects to that master and runs a publisher. The subscriber and publisher node are the basic ones from the ros tutorials.

When publishing, I get the following error on the subscriber's side:

[ERROR] []: Exception thrown when deserializing message of length [] from []: Buffer Overrun

if I have sent an empty message (empty string) or

[ERROR] []: Exception thrown when deserializing message of length [] from []: basic_string::_S_create

in case it is not empty.

I was able to find one related post here: #q42336. As I understand it might be an endianness problem and in fact the arm device is little endian while the other is big endian.

I think that the problem lies on the publisher's side, in which the length of the ros message is written big endian, as such a crash is produced on the subscriber which reads it little endian. How can this be solved?

Thank you for your time.
