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.

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.

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.

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

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.

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