Hi Archie.....

Few things

The euwingui dlls are 32 bit dlls, and while your system may be able to find them in euphoria/bin, but it will be able to find them in windows/Syswow64 and this is where you should place them on a 64 bit system. On a 32 bit system the should go in windows/system. Won't go into why now, google it if you want.

Second the path thing. IMHO the Eu environment variables are a a thing of the past and should be confined to history, and are entirely replacable by eu.cfg.

However, if you installed Eu with the installer, then you will have had a few environment variables added

Your %PATH% variable will have had c:\euphoria\bin added to it. This tells your system where to search when you enter a program. For instance you will be able to type eui from anywhere in your computer, and your system will be able to find it within c:\euphoria\bin. To check if it has been added, open up a command console (start/search box/ cmd), and type path or echo %PATH%. You should see the path enironment variable with the euphoria directory at the end.

The EUDIR and EUINC environment variables tell Euphoria where euphoria lives and where you are putting include files. The message

<0074>:: Errors resolving the following references: 
..\..\include\ewguties.ew (35): NULL 
return NULL ^ 

is an instruction for the interpreter to look in a very specific place. The error message is telling you it can't find it. The ..\ are instruction for one directory up, then go down into include and look for ewguties.ew. If your EUINC points to where you have some includes, it will look for these, by adding the instruction onto each of these - ie

c:\Euphoria\euwingui2\include\..\..\include 

in other words

c:\include 

as well as the current location - 2 up - then into include

(This is only one example of the search - it will go through the rest trying to find it)

A simple solution would be just to put the includes directly into c:\euphoria\include, which you have kind of alluded to, but not done. It will clutter the include folder up, but it will work.

This is why I believe the environment variables add confusion rather than helping. The EUDIR is always searched for the include folder, but then the eu.cfg should be used to specify other include folders for individual specific programs or specify them directly in your program, eg

include c:\Euphoria\euwingui2\include\ewguties.ew 

or if you use eu.cfg

-I  c:\Euphoria\euwingui2\include 
(or wherever you put the includes) 
and change the program to just look for the include, and not specify a path 

Hope this has given you some pointers

Cheers

Hi Chris,

I'd like to ask about the config file please.

Let's say i wanted to set up euwingui2 and use a config file, and that i was starting from scratch. I've installed OE using the installer, which set my path automatically to c:\Euphoria. I want to use config files from now on. At this point do i need to set any environment variables myself? For example, do i need to set up EUDIR and EUINC?

Now let's say i've unzipped euwingui2 to c:\Euphoria\euwingui2. There's a \bin subdirectory (with euconvert.dll, euwingui.dll, euconvert.e, and euwingui.ico in it) and an \include subdirectory (with euconvertinc.e, euwingui.ew, and ewguties.ew in it). Now if i'm going to be using a config file, do i still need to copy the dll's to \windows\sysWOW64? (BTW that means copy, right, not move from their original location - correct?) Do i need to move or copy any other files from \euwingui2 to anywhere else, or will the config file somehow take care of things from the files' original location? And finally, what should i put in the config file, and where should i save it to?

Sorry for the tedium, but once i understand this i'll be able to manage other downloads without having to ask again - i hope

TIA

Hi

Just a quick deviation from this subject - euwingui2 does NOT run with eu 4.05 - make sure you use eu 4.1. It's a dll interface thing again.

You can also delete \bin\euconvert.e - it is replaced by \include\euconvertinc.e (courtesy of Jim)

Cheers

Hi Chris

Thanks for your advice.
The story so far...

• My environment variables are: EUDIR = c:\Euphoria and PATH = c:\Euphoria\bin;
  
• I deleted EUINC - there was nothing in it, and i gather you said i don't need it; will Eu ever complain about there being no EUINC if i use cfg files from now on?
  
• i unzipped euwingui2 to c:\Euphoria\euwingui2
  
• i copied euconvert.dll and euwingui.dll (from c:\Euphoria\euwingui2\bin) to c:\Windows\sysWOW64
• i didn't copy any include files (euconvertinc.e, euwingui.ew, and ewguties.ew - from c:\Euphoria\euwingui2\include) to any other place (like c:\Euphoria\include)
  
• then i went to c:\euwingui2\demos and created eu.cfg. It's got:
  -I ..\bin
  -I ..\include
  Just that. Literally. No absolute path. No [interpret:windows]. Absolutely nothing else.
  
• then i tried to run c:\Euphoria\euwingui2\demos\button.exw
  
• i got an ex.err file with "C:\EUPHORIA\INCLUDE\euconvertinc.e:41 in function v3_c_func() a machine level exception..." (and other things) - but at least Euphoria found the includes, right?
  
  Can you tell from this whether i've set up Eu, euwingui2, and the cfg file correctly? And i am running Eu4.1 Is there anything else i should do??
  
  TIA

OH - Well done!

What did you replace AM=E_ATOM and SQ=E_SEQUENCE with?

I'm using the version that's available from here: http://openeuphoria.org/wiki/view/windows_download.wc
i downloaded the oE 4.1B2 Win64 installer. when saved, the file is named euphoria-4.1.0-x64.exe
i accepted all the default settings, and allowed the program to set the environment variables automatically
then i rebooted, saved euwingui2, and did the tweaks we've discussed in the past few days...

BTW, i did install Eu 4.0 first (to c:\Euphoria), again, using the installer provided and allowing it to change the environment. Then i used the uninstaller, and replaced it with Eu 4.1. I don't suppose i need to go back and mess with the registry, do i?? The manual talks about doing that, but i haven't through lack of confidence. Could that be the problem?

Cheers,
arch

Hi, yes, these are 32 bit dlls, so you must use 32 bit Eu, and it must be version 4.1.

Cheers
