As a result, it is possible to -easily port many significant UNIX programs without the need for -extensive changes to the source code. This includes configuring and -building most of the available GNU software (including the development -tools included with the Cygwin distributions). Even if the -compiler tools are of little to no use to you, you may have -interest in the many standard UNIX utilities.

None of it -is shareware. You don't have to pay anyone to use it but you should be -sure to read the copyright section of the FAQ for more information on -how the GNU General Public License may affect your use of these -tools. If you intend to port a proprietary application using the Cygwin -library, you may want the Cygwin proprietary-use license. -For more information about the proprietary-use license, please go to -<ulink URL="http://www.redhat.com/software/tools/cygwin/">http://www.redhat.com/software/tools/cygwin/ -</ulink>.

We could have -done this by rewriting large portions of the source to work within the -context of the Win32 API. But this would have meant spending a huge -amount of time on each and every tool. Instead, we took a -substantially different approach by writing a shared library -(the Cygwin DLL) that adds the necessary UNIX-like functionality -missing from the Win32 API (fork, spawn, signals, select, sockets, -etc.). We call this new interface the Cygwin API. Once written, it -was possible to build working Win32 tools using UNIX-hosted -cross-compilers, linking against this library.</para> - -<para>From this point, we pursued the goal of producing native tools -capable of rebuilding themselves under Windows 9x and NT (this is -often called self-hosting). Since neither OS ships with standard UNIX -user tools (fileutils, textutils, bash, etc...), we had to get the GNU -equivalents working with the Cygwin API. Most of these tools were -previously only built natively so we had to modify their configure -scripts to be compatible with cross-compilation. Other than the -configuration changes, very few source-level changes had to be -made. Running bash with the development tools and user tools in place, -Windows 9x and NT look like a flavor of UNIX from the perspective of -the GNU configure mechanism. Self hosting was achieved as of the beta -17.1 release.</para> - -</sect1> - -DOCTOOL-INSERT-ov-ex-unix -DOCTOOL-INSERT-ov-ex-win -<sect1 id="highlights"><title>Highlights of Cygwin Functionality</title> -DOCTOOL-INSERT-ov-hi-intro -DOCTOOL-INSERT-ov-hi-win9xnt -DOCTOOL-INSERT-ov-hi-perm -DOCTOOL-INSERT-ov-hi-files -DOCTOOL-INSERT-ov-hi-textvsbinary -DOCTOOL-INSERT-ov-hi-ansiclib -DOCTOOL-INSERT-ov-hi-process -DOCTOOL-INSERT-ov-hi-signals -DOCTOOL-INSERT-ov-hi-sockets -DOCTOOL-INSERT-ov-hi-select -</sect1> -</chapter> |
