+ <question>
+ <p>What are all these <code>system-*</code> "virtual
+ packages" that are sometimes present, but that I can't
+ seem to install or remove myself?</p>
+ </question>
+ <answer>
+ <p>
+ Packages with names like <code>system-perl</code> are
+ placeholder packages. These do not contain actual files, but
+ merely serve as a mechanism for fink to know about programs
+ that have been installed manually outside of fink.
+ </p>
+ <p>
+ Starting with the 10.3 distribution, most placeholders
+ aren't even real packages that you can install and remove.
+ Instead, they are "Virtual Packages", package data
+ structures generated by the fink program itself in response
+ to a preconfigured list of manually installed programs. For
+ each virtual package, fink checks for certain files in
+ certain locations, and if they are found, considers that
+ virtual package "installed".
+ </p>
+ <p>
+ You can run the program <code>fink-virtual-packages</code>
+ (part of the fink package) to get a listing of exactly what
+ fink thinks is installed. Adding the <code>--debug</code>
+ flag will give lots of diagnostic information about exactly
+ what files fink is checking.
+ </p>
+ <p>
+ Unfortunately, there is no mechanism by which you can
+ install an arbitrary program yourself (outside of fink) and
+ have fink recognize that program rather than trying to
+ install its own version of it. It's just too difficult in
+ the general case to be able to check configure and compiler
+ flags, pathnames, etc.
+ </p>
+ <p>
+ Here are the most important virtual packages that fink
+ defines (as of fink-0.19.2):
+ </p>
+ <ul>
+ <li>system-perl: [virtual package representing perl]
+ <p>
+ Represents <filename>/usr/bin/perl</filename>, which is
+ part of the default OS X installation. This package also
+ provides <code>system-perlXXX</code> and
+ <code>perlXXX-core</code> according to the version X.X.X
+ of that perl interpreter.
+ </p>
+ </li>
+ <li>system-javaXXX: [virtual package representing Java X.X.X]
+ <p>
+ Represents the Java Runtime Environment, which is part of OS
+ X (and Apple's Software Update). See
+ <link url="http://www.apple.com/java";>Apple's Java
+ page</link> for more information.
+ </p>
+ </li>
+ <li>system-javaXXX-dev: [virtual package representing Java X.X.X development
headers]
+ <p>
+ Represents the Java SDK, which must be manually
+ downloaded from <link
+ url="http://connect.apple.com";>connect.apple.com</link>
+ (free registration required) and installed. If you have
+ updated your Java Runtime Environment, your SDK may not
+ be updated automatically (and may even be deleted!).
+ Remember to check for (and download and install if
+ necessary) the SDK after installing or upgrading your
+ Runtime Environment. See also <xref
+ chapter="comp-general" section="system-java">this FAQ
+ entry</xref>.
+ </p>
+ </li>
+ <li>system-java3d: [virtual package representing Java3D]</li>
+ <li>system-javaai: [virtual package representing Java Advanced Imaging]
+ <p>
+ Represent Java extensions for 3D graphics and image
+ processing, which must be manually downloaded from Apple
+ and installed. See <link
+ url="http://docs.info.apple.com/article.html?artnum=120289";>Apple'
+ webpage</link> for more information.
+ </p>
+ </li>
+ <li>system-xfree86: [placeholder for user installed x11]</li>
+ <li>system-xfree86-shlibs: [placeholder for user installed x11 shared
libraries]
+ <p>
+ Represent Apple's X11/XDarwin, an optional part of OS X
+ (X11User.pkg). These packages provide <code>x11</code>
+ and <code>x11-shlibs</code>, respectively. See
+ also <xref chapter="comp-packages"
+ section="cant-install-xfree">this FAQ entry</xref>.
+ </p>
+ </li>
+ <li>system-xfree86-dev [placeholder for user installed x11 development tools]
+ <p>
+ Represents Apple's X11/XDarwin SDK, an optional part of
+ OS X (X11SDK.pkg). This package provides
+ <code>x11-dev</code>. See also <xref
+ chapter="comp-packages"
+ section="cant-install-xfree">this FAQ entry</xref>.
