Hi! I've opened an issue on github about popen()/pclose() functions and 'FIFO and named pipes drivers' option dependecy: https://github.com/apache/nuttx/issues/11435 [https://opengraph.githubassets.com/2024b48250bb10d4358854e050b2313fb90bac648f5884ae80f495f4348981d2/apache/nuttx/issues/11435]<https://github.com/apache/nuttx/issues/11435> Make OPEN option select FIFO and named pipes configuration · Issue #11435 · apache/nuttx<https://github.com/apache/nuttx/issues/11435> When enabling open()/pclose() functions, in order to use them, 'FIFO and named pipes drivers' option must be enabled but there is no sign of its dependecy.

Gustavo, could you please submit a patch? Case you cannot, I can do it.

That way the POPEN option will appear in the menus when FIFOs are disabled.

Just like Nathan said... shouldn't appear it's dependency on this config?

Yes, this message pops up when trying to compile: [cid:ii_18c8a10674acb971f161] the problem seems to be in the apps/system/popen. Should any other configuration be applied besides enabling the popen()/pclose() functions? ________________________________ De: Alan C.

I remember using popen() in the past to get the result of other program output.

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. [cid:ii_18c8a10674bcb971f162] BR, Gustavo.
