鏈接與gl3n錯誤

Question

當我嘗試對OpenGL庫作爲

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

什麼是_Dmodule_ref鏈接到我最小的程序

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

gl3n作爲

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 

它的錯誤？

Answer 1

_Dmodule_ref是druntime中的特殊符號。這裏的問題很可能與當前工作目錄中錯誤安裝的druntime或object.d有關。

1）編譯hello世界工作嗎？如果沒有，可能有助於重新安裝dmd/druntime/phobos。

2）在名爲object.d的gl3n應用程序所在的目錄中是否有文件？如果是這樣，請重新命名它，或者因爲dmd可以在那裏看到它並且感到困惑，因爲它想讓它作爲一個自定義的druntime。
