 Posted: Tue Jan 11, 2011 8:44 pm Post subject: I'm lost with importing and linking... |
 |
|
I'm using DDT (eclipse plugin) and trying to use Derelict 2.
I've builded it as written in the documentation, and some files have been generated in DERELICT\lib and DERELECT\import
I typed this in complie options.
| Code: | -ID:\Jun\Programming\D\lib\Derelict\import
-ID:\Jun\Programming\D\lib\Derelict\lib\DerelictGL.lib
-ID:\Jun\Programming\D\lib\Derelict\lib\DerelictGLU.lib
-ID:\Jun\Programming\D\lib\Derelict\lib\DerelictSDL.lib
-ID:\Jun\Programming\D\lib\Derelict\lib\DerelictUtil.lib |
I compiled and got these errors.
| Code: | bin\OpenGLTest.obj(OpenGLTest)
Error 42: Symbol Undefined _D8derelict3sdl3sdl11DerelictSDLC8derelict3sdl3sdl17DerelictSDLLoader
bin\OpenGLTest.obj(OpenGLTest)
Error 42: Symbol Undefined _D8derelict6opengl2gl10DerelictGLC8derelict6opengl2gl16DerelictGLLoader

Error 42: Symbol Undefined _D8derelict6opengl3glu12__ModuleInfoZ
bin\OpenGLTest.obj(OpenGLTest)
Error 42: Symbol Undefined _D8derelict6opengl2gl12__ModuleInfoZ |
I think I'm doing wrong with linking lib files. Should I use dsss(if I should, please let me know how to use it)? please help me! |

you need add complier flag such as:
-L-ldl
-L-lDerelictGL
-L-lDerelictGLU
-L-lDerelictSDL
-L-lDerelictUtil |

Thank you for the reply! Actually, it did not work but you help me to find out what was missing with my build command.  |

whenever I try to add it always says: | Code: | | Error: unrecognized switch '-ldl' |
Any ideas? using Dmd2.
UPDATE Got it working. Had a screwy flag in my /etc/dmd.conf. |

I have a similar problem. I'm using Eclipse wich DDT,
I just pus in dmd.conf this :
... -I/usr/include/d/Derelict2/import -L-ldl -L-lDerelictGL -L-lDerelictGLU -L-lDerelictSDL -L-lDerelictUtil
I install Derelict2 from svn in /usr/include/d/Derelict2
I get this errors when i try to compile :
/usr/bin/ld: cannot find -lDerelictGL
/usr/bin/ld: cannot find -lDerelictGLU
/usr/bin/ld: cannot find -lDerelictSDL
/usr/bin/ld: cannot find -lDerelictUtil
collect2: ld returned 1 exit status
And the program is :
import std.stdio;
import derelict.sdl.sdl;
void main () {
writeln("Aja");
DerelictSDL.load();
}
So, why it can find the libs to link ??? |

Most likely because you didn't put the Derelict libraries on the link path. If that's the case, you need to tell the linker where to find them. I'm not a Linux user, but I assume it will be:
-L-L/path/to/libraries
Also, it's probably not a good idea to put all of that in DMD.conf. You'll have to update it every time you install a new version of DMD. Better to put it in the project settings.
Alternatively, you can use pragmas in the source code, using the full path to the libraries:
pragma(lib, "/path/to/libraries/libDerelictSDL.a");
In which case you don't need to add anything on the command line.

Thanks! Ok, I move it to proyect settings wichout any problem, and I actually i not have any problem wich Derelict SDL ( I can compile basic examples wichout any problems), but wich DerelictGL I have problems....
I try this :
| Code: |
import derelict.opengl.gl;
import derelict.sdl.sdl;
import derelict.util.compat;
void main () {
writeln("Aja");
DerelictGL.load();
}
|
And i get this gigant error/warring mensages from the linker :
| Code: |

For me looks like there a error linking wich OpenGL libs and/or I missed to install some opengl-dev package.
I'm compiling wich :
-I/usr/include/d/Derelict2/import -L-L/usr/include/d/Derelict2/lib/ -L-ldl -L-lglut -L-lGL -L-lGLU -L-lDerelictSDL -L-lDerelictUtil -L-lDerelictGL -L-lDerelictGLU
Note : Removing or adding -L-lglut -L-lGL -L-lGLU, not changes anything |

AutoAnswer:
OK, I find a previus post wich a similar problem.... (http://www.dsource.org/forums/viewtopic.php?p=26799&sid=ed338468d1d099d801f1d8e5d3c36a4f) So
1) I moved all .a lib files of Derelict to /usr/local/lib/derelict2/
2) I'm compiling wich : | Code: | | -I/usr/include/d/Derelict2/import -L-L/usr/local/lib/derelict2/ -L-ldl -L-lDerelictUtil -L-lDerelictSDL -L-lDerelictGL -L-lDerelictGLU |
3) I put this pragma : | Code: | | pragma(lib, "/usr/local/lib/derelict2/libDerelictUtil.a"); |
Now works wich dmd |

That's because you do not need to link to any of those libraries to use Derelict. Derelict loads the shared libraries manually, so you don't need to link with any of them on the command line at compile time. And GLUT has nothing to do with any of this anyway.

This is redundant. In 2), you are already passing DerelictUtil on the command line. You can remove this line and it should work.

I know, andlike I said, I have the same problem that is showed in aprevius post. DMD 2.052 have some strange problem linking, and wichout these pragma, not links well DerelictUtil.
I'm sorry that you not read my last line that said "Now works with dmd"...
In any case, thanks. |
