Bug 8554 – ddemangle is doing nothing on 64 bit linux

dmd <params> | ddemangle works on win xp, but for the same linker error ouput it does not for 64 bit arch linux with ddemangle OPTLINK (R) for Win32 Release 8.00.12 Copyright (C) Digital Mars 1989-2010 All rights reserved. http://www.digitalmars.com/ctg/optlink.html main.obj(main) Error 42: Symbol Undefined void main.IKlazz.accept!(int).accept(main.Visitor!(int).Visitor) --- errorlevel 1 on windows without ddemangle OPTLINK (R) for Win32 Release 8.00.12 Copyright (C) Digital Mars 1989-2010 All rights reserved. http://www.digitalmars.com/ctg/optlink.html main.obj(main) Error 42: Symbol Undefined _D4main6IKlazz13__T6acceptTiZ6acceptMFC4main14__T7VisitorTiZ7VisitorZv --- errorlevel 1 on linux with ddemangle ..main.o: In function `_Dmain': main.d:25: undefined reference to `_D4main6IKlazz13__T6acceptTiZ6acceptMFC4main14__T7VisitorTiZ7VisitorZv' collect2: error: ld returned 1 exit status --- errorlevel 1

I don't suppose there's any chance you were piping stdout instead of stderr by mistake?

This kind of thing could happen to me easily :) but in this case, considering that I posted output of dmd piped to ddemangle and printed, I think not - the output mangled, so it seems that ddemangle did not processed it, just forwarded. Unfortunately I don't have exact command I used and I can't replicate now, it was long time ago.

Did you try this: dmd <params> | ddemangle 2>&1 From your command-line, it looks like you're just piping stdout to ddemangle, and stdout, since it's not redirected, just gets passed through to the terminal unmodified.

I did not try it but it seems reasonable. If DMD/Linker outputs errors to stderr, then it makes sense.
