- What's New on Jun 18, 2013:
- Source code
for a (famous ?) block-game has been contributed by Mr. Soju TANAKA,
and it should work fine with either of GrWin/GrWinC under any compiler system supported by GrWin/GrWinC.
"The source code may be used and modified freely only for NON COMMERCIAL purposes."
- What's New on Jun 17, 2013:
- A release candidate RC3 for the official release of GrWin 1.1.0 is now available to download here.
Some new featuers are added.
See details in the User's Manual.
- What's New on July 27, 2011:
- New installer packages with some fixed bugs and improvements on installers have been
If you encountered some installation troubles on "GrWinC version 1.0.0" please try new one.
- What's New on July 21, 2011:
- Now that "GrWinC version 1.0.0" has been released as the direct descendant of the beta versions of
"GrWin Graphics Library" released so far, a toolkit, GrWinCTk, and installers for many compiler systems are available
GrWinC is a free systyem
composed of the grwnd.exe graphics server and library files of graphics routines for Fortran and C/C++ available under
many compiler systems
on Windows 7/Vista/Xp/2000/NT/Me/9x (x86, x64) platforms.
Using this system you can enjoy free graphics programming on Windows
even if you have no experience on Windows programming.
The builds 1.0.x (x is the build version) are of the first and the last official version 1.0 which supports 16-bit Windows such as Windows 9x/Me. If any serious bugs are found, another 1.0.x might be released, but there is no plan to extend the version. In 1.1.x or later, improvements of efficiency and/or adding more features are planned. Please be patient until then.
Bug reports are very appreciated. I however would make an apology in advance for not replying to every of your reports. Thank you.
The PGPLOT implementation with GrWin make you ready to use high level graphics routines, such as for graphs with hidden lines and/or contour diagrams, etc., in your application. The f2c is incorporated in each installer with prebuilt binaries for a system which do not have a corresponding Fortran compiler, such as Borland C++ Compiler 5.5, Digital Mars C/C++ Compilers, etc.. For the compiler systems GrWin supports having Fortran 9x counter parts, grwin.mod files built from a grwin.f90, by which you do not need to declare the GrWin routines and many parameters in your Fortran 9x source code, are automatically installed when each of the corresponding installers is performed.
The EPS (Encapsulated PostScript) is supported by GrWin, as one of output file formats among others, and so users can make high quality documentations using TeX systems, etc..
To install GrWinC 1.0.0 on your PC, download one of
the installers (*.msi)
appropriate for your system within
the Supported compiler systems,
and then double click the msi file obtained to launch the installer.
After the installation,
if the GRWINDIR environment variable is not appear with running the set command in a command prompt,
your system shoud be restarted.
On default, some build commands gw<xxx> for console applications and
gw<xxx>w for windows applications with <xxx>'s being file extentions are
installed in the system's bin directory,
e. g., C:\MinGW\bin for a typical MinGW system.
To build, for example, an executable dp.exe from a source file
the following command line applies:
> gwf90 dp
Users of other systems than those supported
can make binary files themselves using
the GrWinC toolkit.
Individual files in the toolkit can be accessed from
Chaotic motion of a double pendulum. (dp.f90)
- GrWinC 1.0.0 can be used freely for noncommercial uses.
- Redistribution of any beta release is prohibited after this release.
- For users to whom noncommercial uses are not approved, a shareware version of GrWin is now being prepared to open.
As well as GrWinC, GrWin also can be used freely for noncommercial uses with a free license for each qualified user.
A release candidate for such shareware version GrWin 1.1.0RC2 free for all is now available here.
- For commercial uses, details are available at Organization for Innovation and Social Collaboration.
*1 CAUTION: v1.9 might have a bug|
*2 The toolkit can be used to build binaries for Intel XE C++ & Fortran.|
*3 built with Visual Studio .Net 2003|
*4 built with Visual Studio 2008|
