I am getting compilation error for posix_spawnp function on Android-ndk - android-ndk

I am using Ubuntu Linux and Android (android-ndk-r21d). When I am compiling my code with ndk-build, I am getting compilation error for posix_spawnp function call. I have included the header <spawn.h> for this function. I am unable to figure what compilation and Link flags I should use for this function in my Android.mk file. Is this function supported on Android-ndk ?

Cross-compile of CPython 3.8 fails at _socket module

I am trying to cross-compile CPython 3.8 using Android NDK toolchains with enabled _socket module but unfortunately compilation failes at:
../Modules/socketmodule.c:6739:5: error: invalid use of undefined type 'struct if_nameindex'
for (i = 0; ni[i].if_index != 0 && i < INT_MAX; i++) {

Whithout _socket module the whole cross-compilation works well, there are no errors.

Problem solved using the latest r23b version of Android NDK.

Building old version of Intel i40e driver on centOS errors

I'm trying to build an old version of the i40e driver for the Intel X710 NIC.
I have to use an old version of the driver because they removed a functionality I need.
The version I'm trying to use is i40e-1.5.23 from 10/5/2016.
If I try to build the latest version, I don't get any errors.
I have installed "Development Tools" packages so Kernel-Devel, gcc...
My current Kernel version is 3.10.0-693.21.1.el7.x86_64
My current CentOS version is 7.4.1708
I tried with different kernel/kernel header versions but still get the same error. I also tried with various version of the i40e driver.
In the readme of the driver it's written that the kernel and kernel header files must be the same version and I'm quite sure they are in my situation.
Here is the output when I try to make in the src folder of the driver :
make[1]: Entering directory '/usr/src/kernels/3.10.0-693.21.1.el7.x86_64'

It looks like the error is comming from kcompat.h.
I can't find any information on how to solve this problem elsewhere so that's why I created this post.
Any help is appreciated.

What can be the problem?

The problem is that the example assumes you're running Node 0.12, but you're running Node 0.10 (0.10.36 by the looks of it). There have been big (backward-incompatible) changes in the way addons are structured in Node 0.12.
Here's the 0.10-compatible version: https://github.com/joyent/node/blob/aa35564ca1c9f3854bc5f7983f2f00cb51f67ffe/test/addons/hello-world/binding.cc
An awesome package that will take care of a lot of the differences between Node versions is nan.

Any help will be great. I feel helpless. If you can suggest resources so I can learn to fix such errors on my own, that would be teaching me how to fish..

You have to include stdio.h in lib/test_readline.cc to define FILE.

Resources
