# ExtUtils::MM\_Cygwin(3perl)

methods to override UN\*X behaviour in ExtUtils::MakeMaker

## NAME

ExtUtils::MM\_Cygwin - methods to override UN\*X behaviour in ExtUtils::MakeMaker

## SYNOPSIS

```
 use ExtUtils::MM_Cygwin; # Done internally by ExtUtils::MakeMaker if needed
```

## DESCRIPTION

See ExtUtils::MM\_Unix for a documentation of the methods provided there.

- os\_flavor

  We're Unix and Cygwin.

- cflags

  if configured for dynamic loading, triggers #define EXT in EXTERN.h

- replace\_manpage\_separator

  replaces strings '::' with '.' in MAN\*POD man page names

- init\_linker

  points to libperl.a

- maybe\_command

  Determine whether a file is native to Cygwin by checking whether it resides inside the Cygwin installation (using Windows paths). If so, use ExtUtils::MM\_Unix to determine if it may be a command. Otherwise use the tests from ExtUtils::MM\_Win32.

- dynamic\_lib

  Use the default to produce the \*.dll's. But for new archdir dll's use the same rebase address if the old exists.

- install

  Rebase dll's with the global rebase database after installation.
