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

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. -- /Jacob Carlborg

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.
