Erros while "Make" the source code #40

Closed jonimessi closed 3 years ago

Get the following warnings while execute "Make"-command: bwctl.c:1934:26: warning: format specifies type 'unsigned long' but the argument has type 'int' [-Wformat] MSS_MIN, MSS_MAX); ^~~ bwctl.c:1926:28: note: expanded from macro 'MSS_MIN'

define MSS_MIN (28)

                       ^~~~

bwctl.c:1934:35: warning: format specifies type 'unsigned long' but the argument has type 'int' [-Wformat] MSS_MIN, MSS_MAX); ^~~ bwctl.c:1927:28: note: expanded from macro 'MSS_MAX'

define MSS_MAX (9 * 1024)

                       ^~~~~~~~~~

When I want to use bwctl -m ... the command does not work. It return error: iperf3: error - unable to set TCP/SCTP MSS: Invalid argument bwctl: local tool exited before expected with status=1

Is it possible that the error depend on the Warnings in the make-command?

Using bwctl Version 1.6.2-1 Running on FreeBSD 10.3 iperf3 Version 3.1.6

The warning in BWCTL is in a printf() called when the MSS value is invalid. It's harmless, but we'll try to get rid of it.

The error you're seeing at runtime came from iperf3, which is maintained by ESNet. I don't believe FreeBSD is one of the supported platforms, which may not be capable of setting MSS.
