链接与gl3n错误

Question

当我尝试对OpenGL库作为

LANG=en dmd -debug -gc -unittest -D -Dd/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/ -w ~/Work/cognia/t_opengl.d -of/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/t_opengl

什么是_Dmodule_ref链接到我最小的程序

import gl3n.linalg; 
pragma(lib, "gl3n"); 
void main(string args[]) { 
} 

gl3n作为

dmd -debug -gc -unittest -D -Dd/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/ -w ~/Work/cognia/t_opengl.d -of/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/t_opengl 

它的错误？

Answer 1

_Dmodule_ref是druntime中的特殊符号。这里的问题很可能与当前工作目录中错误安装的druntime或object.d有关。

1）编译hello世界工作吗？如果没有，可能有助于重新安装dmd/druntime/phobos。

2）在名为object.d的gl3n应用程序所在的目录中是否有文件？如果是这样，请重新命名它，或者因为dmd可以在那里看到它并且感到困惑，因为它想让它作为一个自定义的druntime。
