我正在尝试消除我的链接错误，例如

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/Work/cognia/gl3n/linalg.d:105: undefined reference to `_D4gl3n6linalg15__unittest_failFiZv'

通过使用ddemangle.dgithub 上的 dtools repo 作为

same_command_as_above | ddemangle

但我使用 DMD 2.063.2 和 git master 得到了相同的输出。

ddemangle.d 不是最新的吗？

更新：好的。谢谢！

same_command_as_above 2>&1 | ddemangle

破坏大部分消息，但不是全部。我想知道为什么。这里有几行

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

确保您正在过滤程序发出的输出流。错误通常写入标准错误流，但上面的行只过滤标准输出流。

尝试将您的命令更改为：

same_command_as_above 2>&1 | ddemangle

2>&1将标准错误重定向到标准输出，允许ddemangle过滤标准输出和标准错误。
