Might be easier to use if the OPEN option SELECTED the FIFO and named
pipes. That way the POPEN option will appear in the menus when FIFOs
are disabled.

After enabling 'FIFO and named pipe drivers' I was able to use popen()

dependency on this config?
Thank you!

So, in Kconfig, Example/popen should "depends on" FIFO and named pipe
drivers?

That is because you forgot to enable:

Remember: "git grep" is your friend!

Hi Alan!
Yes, this message pops up when trying to compile:
the problem seems to be in the apps/system/popen.
Should any other configuration be applied besides enabling the
popen()/pclose() functions?

Hi Gustavo,
Do you mean apps/examples/popen is not working?
I remember using popen() in the past to get the result of
other program output.
Best Regards,

Hello everyone!
I have some i2c devices connected to my ESP32 and I can
get their values by using the i2c get command from NuttX.
Now I need my app to extract the value from the response,
so I enabled the popen() and pclose() functions but it
still not possible to use them, is there any other config
that must be enabled? Even the popen example can't find
the method reference.
BR,
Gustavo.
