digitalmars.D - Question about Derelict

reply Nils Hensel <nils.hensel web.de> writes:
Hi,

I finally decided to give Derelic a try to fool around a little in SDL. 
I downloaded Derelic 0.1 from DSource but when I try to import SDL I get 
following error message:

C:\dmd\src\derelict\sdl\events.d(220): cannot implicitly convert 
expression (-1) of type int to ubyte

I understand the problem but why was a constant with the value -1 
declared to be an unsigned integer in the first place? Why is such an 
error in the sources? Everybody must have problems with this declaration 
so in fact Derelict is useless in this state. And what is the workaround?

Regards,
Nils

Hi. For future reference, please post questions about derelict here http://www.dsource.org/forums/viewforum.php?f=19&sid=9311bf5994b3 229dedb8a3d4bbf07ae if possible. If you did not realize, Derilict 0.1 is sorely outdated, roughly a year old. The D compiler has been evolving ever since that time, and the 0.1 release doesn't work with the current D compiler. Your best bet is to get a hold of SVN here http://subversion.tigris.org/ and download the latest version of derelict from its repository. (http://svn.dsource.org/projects/derelict) More instructions can be found here http://www.dsource.org/site/svnclient.php just remember that you use svn.dsource.org/projects instead of svn.dsource.org/svn/projects. Goodluck!

by the ease downloading the archive on dsource ;-)

One of these days I'll get some new zip archives uploaded. Derelict has grown and evolved quite a bit since that 0.1 archive was posted. Until new release archives get posted (the only thing remaining to do before that happens is to implement the Linux scripts for the Build utility), the current version can always be checked out of svn. The "New Users" thread in the Derelict forums (http://www.dsource.org/forums/viewtopic.php?t=828) should go a long way toward getting you started.

It did, thanks. And by the way: Great Work! It's a pity though that Python didn't make it into derelict since it's an awesome language and would be a wonderful addition to any D app in need of scripting support. But maybe someday ... Best regards, Nils

You can always try lua, it is in the bindings project at dsource, and a derelict like version of it is here http://svn.dsource.org/projects/warbots/trunk/current/derelict/lua/ Maybe not as great as python, but it is something.

It will be there eventually, as I really want to use it myself.
