d工具ddemangle.d不輸出DMD + GNU ld進行鏈接錯誤

Question

我試圖還原函數我的鏈接錯誤發生變化，如

dmd -debug -gc -unittest -D -Dd/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/ -w ~/Work/cognia/t_geometry.d -of/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/t_geometry 
/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/t_geometry.o:(.data+0x6d8): undefined reference to `_D4gl3n6linalg12__ModuleInfoZ' 
/home/per/.emacs.d/auto-builds/dmd/Debug-Boundscheck-Unittest/home/per/Work/cognia/t_geometry.o: In function `_D4gl3n6linalg16__T6VectorTfVi4Z6Vector19__unittestL103_7189FNaNbNfZv': 
/home/per/Work/cognia/gl3n/linalg.d:104: undefined reference to `_D4gl3n6linalg15__unittest_failFiZv' 
/home/per/Work/cognia/gl3n/linalg.d:105: undefined reference to `_D4gl3n6linalg15__unittest_failFiZv' 

通過在github上使用ddemangle.d從dtools回購作爲

same_command_as_above | ddemangle 

但我得到相同的輸出使用DMD 2.063.2和git master。

ddemangle.d不是uptodate？

更新：好的。謝謝！

same_command_as_above 2>&1 | ddemangle 

demangles大部分的消息，但不是全部。我想知道爲什麼。這裏有一些行

/home/per/Work/cognia/gl3n/linalg.d:1814: undefined reference to `void gl3n.linalg.__unittest_fail(int)' 
/home/per/Work/cognia/gl3n/linalg.d:695: undefined reference to `_D4gl3n6linalg19__T6MatrixTfVi2Vi2Z6Matrix6__initZ' 
/home/per/Work/cognia/gl3n/linalg.d:695: undefined reference to `_D4gl3n6linalg19__T6MatrixTfVi2Vi2Z6Matrix6__initZ' 
/home/per/Work/cognia/gl3n/linalg.d:1815: undefined reference to `void gl3n.linalg.__unittest_fail(int)' 

線索任何人？

Answer 1

確保您正在過濾程序發出的輸出流。錯誤通常寫入標準錯誤流，但上面的行僅過濾標準輸出流。

試着改變你的命令：

same_command_as_above 2>&1 | ddemangle 

2>&1將標準錯誤重定向到標準輸出，讓ddemangle篩選標準輸出和標準錯誤。

好的。謝謝！
