Not linking correctly with --compiler=ldc2 #146

Closed Kelet closed 11 years ago

Hello,

dub run works with my project which uses Derelict-SDL2. However, if I try to do dub --compiler=ldc2 run I get a linker error:

C:\Users\Kyle\Desktop\keleworld>dub --compiler=ldc2 run
Checking dependencies in 'C:\Users\Kyle\Desktop\keleworld'

collect2.exe: error: ld returned 1 exit status
Error: C:/mingw32/bin/gcc.exe failed with status: 1
Error: LDC compile run failed with exit code 1

Run 'dub help' for usage information.

I am using dub v0.9.19 on Windows 7. My dependencies in my package.json are as such:

"dependencies": {
    "derelict-sdl2" : "~master"       
}

I am trying to use LDC v0.12.0 using their Windows MinGW binaries (ldc2-0.12.0-mingw-x86.7z). These binaries require an up-to-date installation of MinGW. I use their suggested MinGW binaries from http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/gcc-4.8-dw2-release/i686-w64-mingw32-gcc-dw2-4.8.0-win32_rubenvb.7z/download

Here's the output of running the aforementioned command with -v

Is that using a modified package.json file for derelictSDL2? It's not normal that it tries to link against -lderelictSDL2 AFAICS (everything works for me, at least for the git HEAD version of DUB).

If you do have a modified version for building derelict-sdl separately, it appears that the generated library binary still needs to be copied to the MinGW lib folder, so that it becomes visible to LDC.

Kelet commented 11 years ago

Thanks for the information Ludwig --

I am not using a modified package.json for derelictSDL2; however, I did have

pragma(lib, "derelictSDL2.lib");

in my source code, which is obviously the offender. My SDL2 program seems to work without the pragma, so I suppose it's not necessary, but I had picked up the pragma from a tutorial on using Derelict-SDL2 and thus thought it necessary.

s-ludwig commented 11 years ago

Oh I see. Yeah that was necessary before Derelict was available as a DUB package AFAIK.
