Simple question: anyone got derelict working with codeblocks ide 
(www.codeblocks.org)?

IDE supports D and works just fine, but i cant seem to get derelict 
working with it (i get plenty of undefined symbol errors when i try to 
complie sdl stuff with it).

Complier output. This is when compiling dmedia opengl tutorial:

Make sure the derelict modules are on your import path.

They should be. Because if i break paths, error goes like this:

//cut
main.d:2: module sdl cannot read file 'sdl.d'
//paste

So, i think something else is messed up here.

Ofcourse, i can build stuff in dos prompt (derelict works just fine 
there), but because i use codeblocks to write code, dropping to dos and 
compiling stuff feels bit clumsy.

Ah, of course. Missing symbols means the libraries aren't on the linker 
path. Make sure to add them in the project properties.

Had time to play it bit more today and had little progress.

Doesnt rant about symbols anymore, but now i get error:

-------------- Build: Release in sdl ---------------
Compiling: main.d
Error: unrecognized switch '-O2'
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings

It's called "-O2" in GDC, but in DMD it's instead called "-O"

If this was from the settings for the DMD compiler, it's a bug.

By default, Code::Blocks sets the compiler for D projects to be "GNU GDC 
Compiler" at project creation. When creating projects, make sure you 
select "Digital Mars D Compiler" if you are using DMD rather than GDC.

If you have created a project with the wrong compiler you can still 
switch the configuration by going, in the menu, to Project->Build 
Options. The dialog that pops up will have a tree on the left:

Project Name
     |
     |-- Debug
     |-- Release

Select "Project Name". On the right side is a drop down list named 
"Selected Compiler". If it is not set to "Digital Mars D Compiler", find 
it in the list and select it. Unfortunately, changing the compiler 
selection in the root configuration does not change it in the Debug and 
Release configurations. You will need to select each node and do the 
same thing.

I think the Derelict library uses "pragma(lib)" to
load the libraries (e.g. derelictUtil and derelictSDL)

This should work when doing a "one-pass" build/dmd from
the commandline, but when you are working with something
closer to the "Make" build analogy (like Code::Blocks does)
then it probably compiles the code in the first pass and
then links them together in a second link run. And it is
possible that this second run doesn't pick up on pragma(lib) ?


Try including the D libraries explicitly, in Code::Blocks ?
If this works OK, then you have run into this issue - which
is the same as what you get when running GDC and GNU Make.
(GDC does not support the pragma(lib), for linking libraries)

Code::Blocks uses the same model as C/C++, if that helps you.

Incorrect. None of the packages do that. Only the examples.

Sorry, my bad. And it seemed that the OP got it fixed anyway.

Um... this is a newsgroup for the D programming language.
You should ask this on a C++ newsgroup.
(But hint -- C++ is case-sensitive.  rolldice!=rollDice).
