Thanks Jan,

So many different ways. Before trying this I tried CEAN. It seems to work! I might be on my way.

Hi Bob,

I agree on the official way it was hit and miss for me to before I got it 

Step 1
If you have a pre-compiled version of YAWS you need to copy it in the lib 
directory of the your erlang runtime.

Step 2
Create a yaws config file for yaws and place it in the following directory

Step 3
Start a runtime in the following direcoty

Step 4
Start yaws

Step 5
Open explore and navigate to
This should open the YAWS documentation. simular to the web site. This 
indicates that yaws is working.

The steps in the other email is to compile yaws on a windows platfrom. It is 
steps from me when I update erlang runtimes or yaws versions.
If you need more information on it I will exlain it in more detail.

Hi Jan

Thanks for the response. I'm probably being really thick here but I don't 
have that much experience with the way these extensions are added to erlang. 
I didn't really understand much of what you said. The first reply you sent 
some files, unfortunately yaws.app was blocked. Your first email suggested 
it should just run so I copied yaws from the repository (which was 
pre-built) into lib, but how do I start yaws?

I'm about to start on a management console for my project and 
yaws/erlyweb/mnesia is a preferable approach but I also have a good set of 
Java API's to my erlang core and Java/Spring/MySQL is another approach. I 
don't know how much pain I will have to go through to get yaws etc working 
and build up enough knowledge to use it effectively. The fact that there was 
little response does worry me. The project needs to run on Windows, Linux 
and OSX but I develop on Windows because that's where I am most of the time. 
Sorry to ramble on, just thinking aloud. I'm sure it does work (in fact it 
does because the repository version runs in the special erl runtime) but 
right now I see a few individuals that have managed to get things working in 
their very individual ways. It would be 'nice' to have one official way that 
is properly explained and works.

If you could explain in a little more detail what each step does and how to 
perform it, it would be greatly appreciated.

Hi Bob

I have been using YAWS on the Windows platfrom for all my projects and
applications and it works well.

Here is a short list of steps to get yaws to comiple on a Windows box:

Compiling YAWS for Win32
1 Copy yaws-X.XX into lib directory of Erlang
2 Create the following files using the templates in the src direcory of YAWS
   - yaws_vsn.erl
   - yaws_generated.erl
3 Create the mime_types.erl file from mime_type_c.erl
   - Create a file charset.def in the src directory of YAWS
   - Compile mime_type_c.erl
   - Use the compiled mime_type_c:compile(). to generage mime_types.erl
4 Create yaws.app file
5 Create an Emakefile

I hope this helps.

Jan Jacobs
