NAME ^

README.cygwin - Parrot under Cygwin

SYNOPSIS ^

Parrot builds out of the box under Cygwin after export PATH=`pwd`/blib/lib:$PATH

There are official cygwin parrot packages available via http://cygwin.com/setup.exe.

  parrot libparrot0 libparrot-devel parrot-perl6 parrot-languages

Some tweaks are needed for different names for the ffi to some dll's. See "loadlib DLL versioning"

Packages ^

You'll need the following Cygwin packages to run and build Parrot by your own.

Runtime requirements:

  libreadline6 ncurses libintl8 libgmp3 libgdbm4

Optional requirements:

  libicu38 libpq5 openssl

  for opengl: w32api opengl or libglut3 xorg-x11-base xorg-x11-bin-dlls

Build requirements:

  gcc make perl parrot readline libncurses-devel libgmp-devel
  libgdbm-devel pcre-devel

Optional build requirements:

  libicu-devel openssl-devel 

  for Cygwin/X opengl: freeglut libglut-devel xorg-x11-devel

Optional perl packages for testing:

  L<Test::TAP::HTMLMatrix> if you want to run the language smoke tests
  with C<make languages-smoke>.

  L<Test::Base> for some APL language tests.

  perl L<Moose> for smartlink

  perl L<Test::Perl::Critic> and L<Perl::Critic>
Cygwin subversion and perl
If you use SVN to get a copy of Parrot, you should use the Cygwin SVN and not the TortoiseSVN client to avoid build errors. Similarly you will need Cygwin Perl rather than ActiveState or Strawberry Perl.
icu
Note that ICU is now optional, you can build Parrot without it, by not installing it or asking Parrot to ignore it (--without-icu).
opengl
You can use the w32api and opengl packages for native Windows opengl support, or the freeglut package for the X Server.Configure.pl will detect freeglut if freeglut is installed and DISPLAY is set, otherwise it checks for w32api and opengl with GLUT. 
  Determining if your platform supports OpenGL.............yes, freeglut 3.4.
  Determining if your platform supports OpenGL...................yes, GLUT 3.
  Determining if your platform supports OpenGL............................no.
Required packages: 
  w32api opengl
or 
  freeglut libglut-devel xorg-x11-devel xorg-x11-base xorg-x11-bin-dlls
SDL
SDL references cygSDL-1-2-0.dll, which is only in cygports http://news.gmane.org/gmane.os.cygwin.ports.announce
aio
libaio-devel "Linux-native asynchronous I/O access" is not available for cygwin, and as the name says it will never be :)

BUILD ^

  export PATH=`pwd`/blib/lib:$PATH
  perl Configure.pl
  make
  make test # see PLATFORMS for known issues.
  make reallyinstall

TODO ^

Makefile tuning
Rename libparrot.dll to cygparrot0_8_2.dll and create an interim libparrot.dll.a 
  [perl #56998] [TODO]  rename cygwin dll to cygparrot$MAJOR_$MINOR_$PATCH.dll
  [perl #56562] [PATCH] root.in: add cygwin importlib
loadlib DLL versioning
Use cyg*-1.1.dll naming conventions instead of lib*.so.1.1 names for loadlib, the FFI.Thanks to the "Windows DLL Hell" and the impossibility of file hardlinks, windows dll names are versioned, so the loadlib function or the various pir's needs more logic.Either add the version to each loadlib call, and stem the version from POSIX versions within get_path(), or add an optional version argument to loadlib for win32. Or just fix all the pir's, which will be easier when exceptions work again.
Features
Threads, Events, and Signals are missing.
