I have a static library (libDerelictSDL2.a) in 
/usr/lib/Derelict3. What I want to to is just link to that. My 
code does not use anything from it.

My .d file is icy.d.

I try to compile using:

a) dmd icy.d -I/usr/lib/Derelict3 -L-lDerelictSDL2
b) dmd icy.d -L-I/usr/lib/Derelict3 -L-lDerelictSDL2
c) dmd icy.d -L-lDerelictSDL2

None works, and the error is:



/usr/bin/ld: cannot find -lDerelictSDL2
collect2: ld returned 1 exit status
--- errorlevel 1

Why can't it find it? I have set the linker's path correctly (I 
think).

Try:

$ dmd icy.d -L-L/usr/lib/Derelict3 -L-lDerelictSDL2

You can also supply the library directly:

$ dmd icy.d /usr/lib/Derelict3/DerelictSDL2

Thank you very much!!

 $ dmd icy.d -L-L/usr/lib/Derelict3 -L-lDerelictSDL2

This works fine!

$ dmd icy.d /usr/lib/Derelict3/DerelictSDL2

This doesn't because dmd thinks that I'm talking about a .d file.

Hmm, that wasn't quite right, try this:

$ dmd icy.d /usr/lib/Derelict3/libDerelictSDL2.a

(Or whatever the full path to the library is)

I don't know why, but the dl library is needed. Thank you for 
your help.

This is most likely because Derelict uses dynamic loading of modules at
runtime.
