After succesful building of the Derelict libraries using: 'make
-flinux.mak DC=dmd', I am unable to compile the provided example
code:
http://svn.dsource.org/projects/derelict/branches/Derelict2/doc/index.html

They look like linker problems to me.

rdmd test.d -Iinclude/Derelict2/import/

test.o:(.data+0x10): undefined reference to
`_D8derelict6openal2al12__ModuleInfoZ'
test.o:(.data+0x18): undefined reference to
`_D8derelict6opengl2gl12__ModuleInfoZ'
test.o: In function `_Dmain':
test.d:(.text._Dmain+0x3d): undefined reference to
`_D8derelict6openal2al10DerelictALC8derelict6openal2al16DerelictALLoader'
test.d:(.text._Dmain+0x61): undefined reference to
`_D8derelict6opengl2gl10DerelictGLC8derelict6opengl2gl16DerelictGLLoader'
collect2: ld returned 1 exit status
--- errorlevel 1

gdc gave an different kind of error:
include/Derelict2/import/derelict/util/compat.di:64: Error:
identifier 'c_long' is not defined

Using a makefile generated errors similar to those for (r)dmd.

dmd 2.059

Solved, missed -of:
rdmd -Iinclude/Derelict2/import/
-Linclude/Derelict2/lib/libDerelictAL.a
-Linclude/Derelict2/lib/libDerelictUtil.a -ofderelict_test test.d

This is ofcourse enough:
rdmd -Iinclude/Derelict2/import/ -oftest test.d
(rdmd -Iinclude/Derelict2/import/ test.d FAILS)

Could anybody explain why an output file specification is necessary?
Or is this a bug?

I don't know, you should not need to specify the -of flag.

This is on Linux? Shouldn't it be something like

rdmd -Iinclude/Derelict2/import -L-Linclude/Derelict2/lib -L-lDerelictAL -L-lDerelictUtil -L-ldl test.d

?

Thnx, this works.

Though I was under the impression that the new Derelict2 hierarchy / d interface files in Derelict2/import reduced the neccesity for command line arguments, that is a Derelict related question.

Condsider this solved.

You may try to use --chatty and compare the output.

Well, it does. With all of the imports in a single directory, you don't need to specify multiple import directories. But you will always need to link with the libraries. The import directory doesn't affect that.
