[swift-users] Compiled and ran Swiften 3.0 on Beaglebone Black and "SendFile" example terminates randomly while transfer

[faisal alghamdi]

Hi Everyone,

I downloaded swiften 3.0 library on the beaglebone black. I installed
openssl lib and its dev headers. I installed all the boost library
component " libboost-all-dev "  and compiled the library using command
./SCons Swiften V=1

First thing while compilation I got an error because
3rdParty/LibMiniUPnPc/src/miniupnpc.c line:77 has a struct with the
name ip_mreqn . I noticed that when I compile on PC the problem does not
occur. However, I renamed the struct and recompiled again and everything
seemed ok and the compilation finished with no errors..

I ran two applications from the examples in Swiften directory
under /swift-3.0/Swiften/Examples/SendFile/ . These example applications
are "SendFile" and "ReceiveFile". I ran "./ReceiveFile JID PASS" example on
the beaglebone and on the other end I used swift client on PC to send a
file to be received by "ReceiveFile" on the beaglebone. I was able to
transfer files (10MB to 100MB files) with no single problem from linux PC
swift client to beaglebone "ReceiveFile" example.

The problem happens when I run the example "SendFile" from the beaglebone
to transfer file to the swift client on linux PC. The connection terminates
randomly while transfer. Sometimes after sending 3MB and some other times
after 20MB... So it's not clear why this happens I debugged using gdb and
here is the backtrace:
