Linker errors all over the place

Hello. I've been trying for ages to compile a test program with Derelict, but with no luck. Here is what I'm trying to compile:

This is a linker error, which means that Derelict is being found and compiled fine. It's apparently breaking down when it tries to link the resultant object files. So you're OK as far as compilation goes.

You didn't say it explicitly, but based on the info you gave I assume you are using DMD on Linux. If that is the case, drop the -UMB and try passing -op instead.

That's right, I should have said I'm on Linux. DMD iis version 1.010, if it makes a difference.

Anyway, -op instead of -UMB doesn't fix things, I just get similar errors:

Once I got Rebuild up and running the problem disappeared! You were really helpful. Thanks enormously.

I'm glad you were able to sort it out.

Im using DMD on Linux.
And im using Phobos, but those errors are only accuring if i import derelict.

I get such errors as kakbarnf, with bud and rebuild:
Sry i cant post them because then there are mysql errors, maybe cause the text is too long Laughing

Edit
It didnt work because there was a language specific letter in it. Here we go:

On Linux, you need to link with libdl for all derelict applications. Derelict uses it internally to load the shared libraries and neither DMD nor GDC link it by default.

EDIT: This was already mentioned in the documentation on loading (loading.html). But since it crops up from time-to-time, I've added a new section to the documentation front page, titled 'Dependencies'. Maybe more people will see it now. If not, I can now mock them and say it's in the docs *twice*!

Bringing my question here. I got the following error compiling simple application with BUD:

Error 42: Symbol Undefined _D8derelict6opengl2gl10DerelictGL4loadFAaZv

OS: XP
Core Lib: Tango

I just had the glXGetCurrentContext -related linker error. It turns out that Bu[il]d freaks out on the version statement, behind which import derelict.glx is hidden. The trick to fix it, is to add the glx.d file manually to the compile command. Works like a charm!

Hi,

I assume all of the output you posted is from a verbose run of Rebuild. It would be helpful if you could post the actual command line you use. Also, are you using Tango or Phobos?
