Need Help: Solver Compilation error

avinashv20 · July 19, 2021, 13:23

Hello everyone. Hope you are doing well in these tough times. I have just started working on OpenFOAM-v2012 and while compiling a solver I am getting the following error:

/home/avinash/OpenFOAM/OpenFOAM v2012/ThirdParty/platforms/linux64/gcc-6.3.0/include/c++/6.3.0/x86_64-pc-linux-gnu/bits/os_defines.h:39:22: fatal error: features.h: No such file or directory
#include <features.h>
^
compilation terminated.

Can anyone help me solve this problem. Thank you.

You should look for features.h . May bit is at another place.

I don't know. I tried to compile my solver using 'wmake' command. And this is the error it keeps displaying.

Guess, the question should be, what compiler do you use for compilation? features.h header is glibc extension (according to https://stackoverflow.com/a/53412982).
