Include time.h header compile errors

[Avramidis, Ilias]

Dear Xvisor Community,


I was wondering If you can help me with two issues that I am facing

I want to use some of the functions that the time.h header provides like the clock() and difftime().

I can see that you are including that header under the path: docs/examples/rpmsg_test.c

However, when I am using the same header under the path : commands/cmd_ping.c

I am getting errors during the compile process.

Is there any chance to help me with that, how I can include the time.h under the cmd_ping.c file?


Also, If I execute more that 2 pings I am receiving this bug:

Any idea how I can fix that?

Many thanks,
Kind regards,
Ilias

Hi Ilias,

The rpmsg_test.c is a user-space application to test RPMSG inside a Guest Linux
whereas cmd_ping.c is a Xvisor command linked with Xvisor binary. The Xvisor
vmm_wallclock.h provides similar functionality as user-space time.h so you can
explore using vmm_wallclock.h

Regarding the crash with 2 pings, can you share steps to reproduce this. I will
try to fix this at my end. I am suspecting some bug in the old lwIP
version we have
integrated in Xvisor.

Regards,
Anup

Sorry I missed to attach.

Basically the steps are:


1) Update IP address giving one from my local network

2) ping another Raspbian host on the local network

3) The first ping works fine

4) the Second in a raw, fails


Thanks!
