How to solve linker errors using DSFML2 with D2 on Ubuntu?

I'm running 64-bit Ubuntu Linux with DMDv2.052, trying to get application working with DSFML2, but I keep running into linker errors.

I built the SFML and CSFML libraries using shared libs + release builds, and installed them, then built the DSFML bindings like this: 


me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/system$ dmd -m64 -lib *.d -of../../../lib/libdsfml-system.a 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/system$ cd ../window 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/window$ dmd -m64 -lib *.d -of../../../lib/libdsfml-window.a 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/window$ cd ../graphics 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/graphics$ dmd -m64 -lib *.d -of../../../lib/libdsfml-graphics.a 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/graphics$ cd ../audio 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/audio$ dmd -m64 -lib *.d -of../../../lib/libdsfml-audio.a

When trying to build a project to use them, I get the following errors: 


me@lappy486:~/devl/d/Gossamer$ dmd -m64 *.d game/*.d graphics/*.d -L"-L/home/me/devl/sfml2/bindings/d/lib -ldsfml-system -ldsfml-window -ldsfml-graphics -ldsfml-audio"

Can somebody help with this? I haven't been able to get it to work.

I don't know what's wrong, but I'd start by removing any complexities you can:

  1. Using .so in D is... "problematic", if possible, use static linkage.
  2. Try to build it in 32bit mode (64 bit is still alpha last I heard)
  3. Try and build a hello world app using the same lib setup.
  4. Don't do the link from DMD, do it explicitly via ld. (Compile something that already works in verbose mode to get a starting point for the command line you will need.)
