# Future::AsyncAwait::ExtensionBuilder(3pm)

build-time support for extensions to "Future::AsyncAwait"

## NAME

"Future::AsyncAwait::ExtensionBuilder" - build-time support for extensions to "Future::AsyncAwait"

## SYNOPSIS

In *Build.PL*:

```
   use Future::AsyncAwait::ExtensionBuilder;
   my $build = Module::Build->new(
      ...,
      configure_requires => {
         ...
         'Future::AsyncAwait::ExtensionBuilder' => 0,
      }
   );
   Future::AsyncAwait::ExtensionBuilder->extend_module_build( $build );
   ...
```

## DESCRIPTION

This module provides a build-time helper to assist authors writing XS modules that provide extensions to Future::AsyncAwait. It prepares a Module::Build-using distribution to be able to make use of the `"Future::AsyncAwait"` extension API.

## FUNCTIONS

### write\_AsyncAwait\_h

```
   Future::AsyncAwait::ExtensionBuilder->write_AsyncAwait_h;
```

This method no longer does anything *since version 0.67*.

### extra\_compiler\_flags

```
   @flags = Future::AsyncAwait::ExtensionBuilder->extra_compiler_flags;
```

Returns a list of extra flags that the build scripts should add to the compiler invocation. This enables the C compiler to find the *AsyncAwait.h* file.

### extend\_module\_build

```
   Future::AsyncAwait::ExtensionBuilder->extend_module_build( $build );
```

A convenient shortcut for performing all the tasks necessary to make a Module::Build-based distribution use the helper.
