how to run pquic with multipath plugins

[ak47for]

I try to run pquic with multipath, but meet many problems, could you pls give the basic command on how to run mpquic?

I have tried following cmd but it crash:

1. server side: ./picoquicdemo -P plugins/multipath/multipath_rr_cond.plugin -P plugins/multipath/multipath_rr.plugin

2. client side: ./picoquicdemo -p 4443 -P plugins/multipath/multipath_rr.plugin -P plugins/multipath/multipath_rr_cond.plugin 127.0.0.1

==crash log== Starting PicoQUIC server on port 4443, server name = ::, just_once = 0, hrr= 0, 2 local plugins and 0 both plugins local plugin plugins/multipath/multipath_rr_cond.plugin local plugin plugins/multipath/multipath_rr.plugin include multipath_cond.plugin... create memory manager for plugin be.qdeconinck.multipath.rtt create fixed block size memory manager Successfully inserted preplugin plugins/multipath/multipath_rr_cond.plugin include multipath.plugin... create memory manager for plugin be.qdeconinck.multipath.rr create dynamic memory manager Successfully inserted local plugin plugins/multipath/multipath_rr.plugin 13cdaad11dd1d5ac: Receiving packet type: 2 (initial), S0, Version ff00001d, 13cdaad11dd1d5ac: <13cdaad11dd1d5ac>, <8d0a8603a507a0a8>, Seq: 0, pl: 1206 13cdaad11dd1d5ac: Decrypted 1206 bytes 13cdaad11dd1d5ac: Crypto HS frame, offset 0, length 275: 0100010f030393df... 13cdaad11dd1d5ac: padding, 927 bytes

I think maybe I didn't get the right way to use it, could you pls show me how to run? thank you very much.

I test with following command and it crash too server: ./picoquicdemo -P plugins/multipath/multipath_rr_cond.plugin client: ./picoquicdemo -P plugins/multipath/multipath_rr_cond.plugin 127.0.0.1

have you executed make in every directory of plugins you used? I solved the Segmentation fault (core dumped) by doing so,

@ak47for Hi! I met the same problem. Have you solved it?

Did you meet the same problem(i.e. return path->send_mtu) and solve it by run make in every plugin under the plugins directory?

Hi! I met the same problem but after compiling plugins with llvm-6(clang-6.0 and llc-6.0), it worked without crash.
