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++) {

^
../Modules/socketmodule.c:6753:62: error: dereferencing pointer to incomplete type
ni[i].if_index, PyUnicode_DecodeFSDefault, ni[i].if_name);

Whithout _socket module the whole cross-compilation works well, there are no errors.
Problem solved using the latest r23b version of 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 ?

I'm maintaining the aerospike package, a client SDK for the Aerospike No-SQL database. On Node.js versions up to and including v11.15.0 this package compiles and works fine. But starting with v12.0.0 I'm getting a compile time error when building the native add-on, that I haven't been able to resolve.
The error occurs in this function (slightly abbreviated):
void Aerospike(Handle<Object> exports, Handle<Object> module)
{
AerospikeClient::Init();
export("client", Nan::New<FunctionTemplate>(client)->GetFunction());
// more exports
}
NODE_MODULE(aerospike, Aerospike)
And the error I'm getting is:

The module uses the older C++ add-on API, not n-api. I'm using the latest version nan v2.13.2.
The error can also be seen in this Travis CI job: https://travis-ci.org/aerospike/aerospike-client-nodejs/jobs/523788617.
The full source code is here: https://github.com/aerospike/aerospike-client-nodejs/blob/2b9554d1158abda58c17cfbd0438d78f0212ef9e/src/main/aerospike.cc#L102
The correct signature for the second arg of NODE_MODULE is void InitializerFunction(Local<Object> exports[, Local<Value> module]) (ref). Handle was removed from v8; it's replacement is Local.
If you're not upgrading to N-API, NAN is a good way to avoid these changes.
When I try to compile android sample app of breakpad, I got this error and have no idea how to resolve it. I'm using Mac OSX 10.11 and android ndk r10e. Many Thanks in advance.

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.
Considering none of the code is my own, I feel helpless. It's an open source tool, and I can't use it.
This is the tool : http://www.gnucap.org/devel/gnucap-2013-04-23.tar.gz

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.
