Hi Dan,<div><br></div><div>OK, I understand: I have actually tried to build wxWidgets <i>after</i> installing Erlang.</div><div>I found some details to be a bit confusing:</div><div><br></div><div>When Erlang is built, there is no warning about a deprecated or absent version of wxWidgets. For me it's like everything was ready to go. Having found that it was not the case, I have tried to follow wxerlang instructions.</div>
<div><br></div><div>So, in the wxerlang build instruction it is said that the wxWidgets build should be static. Because the wxerlang driver has been built successfully and that it need a dynamic library, it didn't occurred to me that building wxWidgets and Erlang in the right order would solve the problem.</div>
<div><br></div><div>Anyway, thanks for letting me know this. I think it would be great if the build instructions could reflect that*, or if by default Erland is not built with wxWidgets support unless a correct static library is found.</div>
<div><br></div><div><br></div><div>Best Regards,</div><div>Cam</div><div><br></div><div>(*) that is, tell the user that on Mac OS X the wxWidgets system library will not be used, and that a fresh build must be made before building Erlang.</div>

On Mac OS X you will need to compile and install wxWidgets by yourself, before compiling erlang. The wxWidgets libs that are included with Mac OS X Leopard is old and is missing some things I require, (e.g. wxStyledTextCtrl which provides erlang syntax highlighting).<br>
<br>
See compiling instructions here:<br>

I've been working on a library that does much of what you describe. It<br>
wraps for the cross-platform GUI library 'wx' that appeared in R13A<br>
release of Erlang/OTP.<br>
<br>
<br>
Yes, I have tested that on Windows and it worked well.<br>
However, on Mac OS X it compiles but I get :<br>
<br>

I didn't find the origin of this problem.<br>
However, I searched and found the symbol was defined in the wxWidgets library included with Mac OS X (libwx_macud_gl-2.8.0.1.1.dylib). Why the library is not dynamically loaded is a mystery to me.<br>
<br>
<br>
<br>
This interface runs the UI as a separate process (a gen_server), it<br>
allows you to specify the application GUI in XML which makes it very<br>
easy to design/modify/update. It allows you to pass in a callback<br>
module to use for the UI issued commands. So it's pretty close to your<br>
design target.<br>
<br>
<br>
It looks very interesting.<br>
However, my application will need to use a widespread format, so any user that has basic skill in HTML can write simple extensions.<br>
<br>
<br>
The problem is that I only started development of this library less<br>
than a month ago, it's as yet unfinished, and as yet badly documented<br>
as it's a work in rapid progress.<br>
<br>
However you may wish to keep an eye on:<br>

I am interested in anything that touches close of far GUI and Erlang.<br>
I will have a look, thanks!<br>

Best,<br>
