RKWard on Windows
|This page has been marked as needing an improvement. This means the page is incomplete, badly structured or otherwise in need of significant improvements. Most importantly, a walkthrough for the installer is needed|
RKWard on Windows is still a very young project. We'd like to encourage you to give RKWard a try on Windows, but if you do, you should expect all sorts of issues, small and large. Please help us by reporting the problems you find.
(Please use the bug trackers to report issues. This section is only meant to document the major deficiencies.)
- The PHP-backend is very slow on Windows, and it may take several seconds for the "Submit"-button to become active in plugins.
Using the RKWard on Windows installer
You need to install R, KDE, and PHP before you can install RKWard.
A windows installer is available at http://cran.r-project.org/bin/windows/base/ .
Installation should be straightforward and does not require any special settings. In cases of doubt, extensive documentation is available from the same url.
Generic instructions for installing KDE on Windows are available at http://techbase.kde.org/Projects/KDE_on_Windows/Installation . For RKWard, proceed as follows:
- Download the KDE Windows installer and run it.
- Be sure to select MinGW4 as compiler mode on the third page of the installer.
- Install the following KDE packages:
- kdebase (in some versions of the installer, this is called kdebase-mingw or kdebase-apps and kdebase-workspace)
- (many additional packages will be installed, automatically).
A windows installer is available at http://www.php.net/downloads.php .
For the purpose of using RKWard, you only need the CLI-client. To install only that, chose "Do not setup a webserver" on the "Webserver Setup" page. On the Components page, you need to select Program/CLI Executable. No other items are needed for RKWard.
The RKWard installer itself is available at https://sourceforge.net/projects/rkward/files/Current_Stable_Releases/install_rkward_0.5.2.exe/download . In the installer you will need to specify the R and KDE installation directories.
Compiling RKWard from source on Windows
Using emerge (recommended)
- Set up emerge as detailed, here: http://techbase.kde.org/Getting_Started/Build/KDE4/Windows/emerge .
This should be all you need to fetch rkward and all dependencies (including R). Note that this will take several hours to complete.
- Currently this has only been tested with the MinGW(4) compiler. You are encouraged to try compiling using MSVC, but quite likely you will run into some problems. Report those on the mailing list, and we will take care of them.
- At times, compilation using emerge will fail. If the build fails on the R or RKWard packages themselves, let us know on the mailing list. If the build fails at an earlier stage (qt / kdelibs / kdebase), you may want to check http://winkde.org/pub/kde/ports/win32/dashboard/ to see whether this is a problem with your particular setup, or a general problem.
- It is not easily possible to re-use an existing R installation in this approach. Should this be a hard requirement, please use the precompiled package, or try the instructions for fully custom compilation, below.
Custom compilation (not recommended)
For info on compiling RKWard of Linux/BSD/similar systems see Building_RKWard_From_Source. The same information basically applies on Windows, once you have set everything up as detailed below.
You need to install KDE, R, and PHP as described above with these extra steps:
- In the KDE installer
- you have to select "Package Manager" Mode (and compiler mode "MinGW").
- install the additional packages "gcc-mingw", "cmake", and check the "Devel" box on "kdelibs-mingw" (a considerable number of further packages will be installed automatically).
- Download and install the latest R tools: http://www.murdoch-sutherland.com/Rtools/
Initial CMake run
When running CMake, you need the following parameters:
- Required, as kde4-config is currently buggy
- -G "MinGW Makefiles"
- Needed to tell CMake to use mingw-make
You may get an error complaining about sh.exe in your path during the CMake run. At this time, if you drop the -G "MinGW Makefiles" and re-run cmake, that seems to work.
Differences in running make
When usually you would write
on windows write
Should you get an error such as
No rule to make target `D:/kde/kde-mingw/lib/libQtDbus4.a'
although D:/kde/kde-mingw is not your installation directory, see this mail: http://mail.kde.org/pipermail/kde-windows/2009-April/003655.html .
