DMD looking for random file on disk when linking

Question

About 20 minutes ago, I tried to compile a project of mine, and it compiled and linked fine into an executable. I added three D source files, edited some code, and tried to recompile. It failed. That in and of itself is nothing peculiar. However, the build output was:

dub build "accord" "--build=plain"
Building package accord in F:\Development\accord\
Target derelict-util 2.0.0 is up to date. Use --force to rebuild.
Target derelict-glfw3 1.1.0 is up to date. Use --force to rebuild.
Target derelict-gl3 1.0.13 is up to date. Use --force to rebuild.
Building accord ~master configuration "application", build type plain.

I am using Mono-D. Any other project I try seems to compile perfectly. I have no idea why Dub is looking in my users directory for a source file. My JSON file is the standard fare generated by Dub with Derelict-Util (v2.0.0), Derelict-GL3 (v1.0.13), and Derelict-GLFW3 (v1.1.0) as dependencies. I have spent some time trawling the interwebs looking for a solution, but might have missed something. If I did, please just point me in the right direction. Thanks!

[EDIT]: I've identified the problem. The linker seems to think that I am building a library, and not an app. I don't know what I did to do that, but I don't know how to fix it. So, my question now is this: how to I change it back? Thanks.

[EDIT]: Nevermind. Changing the build type to executable did nothing.

[EDIT]: I tried using dub v0.9.22 (from v0.9.23) and it appears to link fine. I have no idea what's going on.

Answer 1

I suspect that the source files you added brought some hidden dependencies - go have a look for some imported 'Spirit' module, that should clearify why dmd (not dub(!) - it's dmd which fails to look for said import) can't find the file.

The C:\Users path seems to be a last resort where dmd looks for imported files.

[Edit] It's failing to link the entire thing whereas it should fail to compile all the stuff - that could be a hint either.
