Since I'll be working 99% of the time on Linux, I'll have to post instructions on how to compile WeiDU under windows.

Setting up

Things to download:
- Download cygwin from
- Download Ocaml from (get the version for windows compiled using MinGW, not the one using Microsoft toolchain). Make sure you're using V3.10 or higher.
- Download Tcl/TK (version 8.4) from
- Download any recent Windows version of WeiDU (the latest from works fine)

Things to set up (note: these assume you use default paths, except where noted):
- Install ocaml. To do slightly less configuration, install it in C:\ocaml.
- Install Tcl/Tk.
- Double click setup.exe (the program used to install cygwin). When asked for packages, add the following ones to the standard selection (additional ones will be added automagically by the setup.exe program, to account for dependancies. This is expected):
- from archive: unzip, zip
- from devel: binutils, make, gcc
- from utils: upx
Note: do NOT install ocaml from the cygwin packages; install the one from instead.
- run once start -> programs -> cygwin -> Cygwin Bash shell, wait for it to do some processing, and then simply type ctrl-d to exit.
- Open C:\cygwin\home\something, where something is your Windows username (it should be the only directory in here anyhow). copy and unzip here your Windows WeiDU version (so that you end up with C:\cygwin\home\something\WeiDU\WeiDU.exe as a valid file)
- if present, delete C:\cygwin\home\something\WeiDU\tk83.dll
- if absent from the destination, copy C:\tcl\bin\tk84.dll to C:\cygwin\home\something\WeiDU


Download the latest source package from either beta location or stable location, according to the case.

unzip the source package to C:\cygwin\home\something (so that C:\cygwin\home\something\WeiDU\src\ is a valid file)
- run start -> Programs -> cygwin -> cygwin bash shell, and type the following commands:
- cd WeiDU
- find -exec touch {} \;
- make windows_zip

after a while, you'll end up with weidu, weigui and weinstall in c:\cygwin\home\something\WeiDU, and the Windows zip file in c:\cygwin\home\something.


Problem: Windows is complaining about `as' not being a valid command.
Cause: Sometimes installing tcl/tk will deteriorate your PATHEXT variable.
Check if this is the problem: start -> Run -> cmd.exe <enter> and run `echo %PATHEXT% '. Make sure it has the various Windows executable extensions (.COM;.EXE;.BAT etc.). If the variable only contains ".tcl", to fix you have to right click on My Computer, properties, advanced tab, Environment Variables, and change the user PATHEXT variable from ".tcl" to "%PATHEXT%;.tcl". After that, rebooting might be needed.
