I want to finally convert my project to windows. That means that I want to build it on windows and linux.

The problem is that I have one external c library 'glfw'. I thought that I would just link with it explicitly but actually I am not completely sure how.


So I just added a submodule, cloned glfw and build it as a shared library

lflags "deps/glfw/build/src/libglfw.so"


This is the eps/glfw/build/src folder:

-rwxr-xr-x 1 maik users 142K Mar 30 14:07 libglfw.so.3.2
-rw-r--r-- 1 maik users  18K Mar 30 14:07 Makefile


But If I try to build it with dub, i'll get "./bin/breeze_opengl: error while loading shared libraries: libglfw.so.3: cannot open shared object file: No such file or directory"

But as you can see it is in there. I get the same error with

lflags "deps/glfw/build/src/libglfw.so.3"
lflags "deps/glfw/build/src/libglfw.so.3.2"

Also the path seems to be correct because if I try to add a file that not exisit I get a different error
lflags "deps/glfw/build/src/doesnotexist.so"

/usr/bin/ld: cannot find deps/glfw/build/src/doesnotexist.so: No such file or directory
collect2: error: ld returned 1 exit status

Am I doing something wrong?

Try using Derelict based binding

http://code.dlang.org/packages/derelict-glfw3

I am already using the derelict binding but I want to explicitly link with the .a or .so c lib because I don't have a package manager on windows.

Okay I think I understand know what you mean, I think you meant I should use dynamic loading like this right?

DerelictGLFW3.load("deps/glfw/build/src/libglfw.so");

This works but I am not sure yet that I want to load it at the application level.

I was able to link with a static lib like this

dependency "derelict-glfw3" version="~>2.0.0"
subConfiguration "derelict-glfw3" "derelict-glfw3-static"
sourceFiles "deps/glfw/build/src/libglfw3.a"
libs "Xi" "pthread" "X11" "Xxf86vm" "Xrandr" "pthread" "GL" "GLU" "Xinerama" "Xcursor"
