Hi, I'm trying to link object files from DMD.exe using Microsoft's linker (the one from VS2005), but it gives: D:\dmd>dmd -g -debug -c bla.d D:\dmd>link /OUT:"bla.exe" /DEBUG /PDB:"bla.pdb" /SUBSYSTEM:CONSOLE /MACHINE:X86 bla.obj Microsoft (R) Incremental Linker Version 8.00.50727.42 Copyright (C) Microsoft Corporation. All rights reserved. bla.obj : fatal error LNK1107: invalid or corrupt file: cannot read at 0x14AF I'm trying to do this in order to get a .pdb that VS can use for debugging. I have the impression that that the support for C7 debug information was removed from VS2005 (I remember the beta showed warnings "C7 will be removed!".) I didn't really expect the pdb-generation to work, but I thought the .obj's were standard? L.

L.Nope. DMD uses Intel's OMF format, Microsoft used to use OMF, but since the early 90's they use their own COFF format. Recent Linux stuff is ELF. Besides, every C++ compiler uses its own name mangling. It's a mess.

It's a mess.Where exactly does the name mangling come in? DMD mangles one way, so if microsoft's linker (would have) understood DMD/C's object files, it would simply have used the already mangled names, right? And the debugger just finds the right debug info for the current memory location. Would I perhaps only get mangled names in the debugger in that case? Does the debugger demangle the names, or does an obj contain both mangled and human-readable names? L.

Can't gcc (gdc) compile to COFF? If so, you could try using that compiler, which might work. But the name mangling might indeed bite you. -[Unknown]Hi, I'm trying to link object files from DMD.exe using Microsoft's linker (the one from VS2005), but it gives: D:\dmd>dmd -g -debug -c bla.d D:\dmd>link /OUT:"bla.exe" /DEBUG /PDB:"bla.pdb" /SUBSYSTEM:CONSOLE /MACHINE:X86 bla.obj Microsoft (R) Incremental Linker Version 8.00.50727.42 Copyright (C) Microsoft Corporation.

The problem is people keep creating new "standards" :-("people", riiiiight ; ) Even if the .objs were OK, I guess the MS linker would never be able to generate its .pdb files, since even MS's compiler had different flags for pdb/C7 debug info. Is PDB microsoft only / open ? L.
