## WINDOWS.H and WINDOWSX.H files for Windows version

Q:
  I downloaded the V C++ GUI package for Microsoft Windows from your website and attempted to compile and run the tutorial (TUTAPP.CPP), only to discover that it indirectly required two files named "WINDOWS.H" and "WINDOWSX.H". I don't have either of these files. Where can I get them?

  A:

  WINDOWS.H and WINDOWSX.H are the files that define the interface to the Windows API toolkit. All Windows apps require these files. They are usually provided with your compiler.

  ## Cygnus gcc-win32

  Q:
  Does V work with the Cygwin environment?

  A:

  The standard V distribution includes support for the latest Cygwin compiler (B20 at this writing). There is also occasional discussions of V on the Cygwin mail group.

  ## Missing files/libraries in X

  Q:
  I'm trying to compile your V libraries on Linux and seem to be missing some of the include files for X. The only subdirectories I have beyond include/X11 are Bitmaps and Pixmaps which aren't really include directories. For example, I'm missing the "Xaw" and "Xmu" directories to name a few. Could you direct me to where I could get the extra include files that I require to build the libraries?

  A:

  V assumes that X has been installed on your system in some place, usually something like /usr/X11 or /usr/X11R6 and other related spots. The standard X installation contains the X include files, X libraries, and others. V also needs the Athena widget set, Xaw, and other files. Some systems don't install these (especially Motif only systems), although most do. Almost always, if your system is running X, then the required files are probably there.

  Other that this general information, it is beyond my capability to provide more help about proper installation of X on your system. Check with your system administrator for help on that.

  ## OS/2 Version

  Q:
  Why is the OS/2 Version different or out of sync with the other V versions?

  A:

  The OS/2 version was written and is maintained by Jon Hacker. We do our best to keep versions in sync, but it is not always possible.

  ## Mac Version

  Q:
  When will a Mac version be available?

  A:

  I don't know. Probably never, unless someone volunteers to do the port. For some time, the Mac looked pretty dead, but perhaps the new iMac will be Apple's salvation. But to date, there has not been enough interest expressed for a Mac port. Volunteers?
