The final executables do usually not contain debug infos, but they do contain the path of all object files that were linked. Debuggers will use these to get the debug infos from the object files. Also GDB will load debug infos from the executable. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Struggling to find out what needs changing to stop dsymutil failing. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

I don't understand - why should dsymutil be needed at all? It isn't needed for
gcc.
Au contraire - put the following in test.c:
int main()
{
return 0;
}
then:
$ gcc -v -g test.c -o test
or
$ clang -v -g test.c -o test
You'll notice the last command run by either is dsymutil test.

http://d.puremagic.com/issues/show_bug.cgi?id=4154 --- Comment #11 from Robert Clipsham rob...@octarineparrot.com 2011-06-05 21:50:05 BST --- I may have found what dsymutil is choking on, I can't be sure though - following the steps taken by gcc, then removing the object file it creates before running dsymutil causes dsymutil to complain that object file does not exist. Curious, I inspected the binary with a hex editor, and it appears ld left some information in there that dsymutil requires, a list of object files. It seems ld doesn't do this for dmd, so I suspect there's something else we're not outputting that's required, or some flag we need to pass to ld. I blame ld, as there is no mention of the object file(s) in themselves before linking. I'll hunt a bit further, I'm not sure how much I can do without more knowledge of what's going on. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

http://d.puremagic.com/issues/show_bug.cgi?id=4154 --- Comment #6 from Robert Clipsham rob...@octarineparrot.com 2011-06-04 00:56:44 BST --- I've run out of time to work on this for now, my initial commit is at https://github.com/mrmonday/dmd/commit/c7fed0fbe5319de507fd0afb4c574bdb4e54699f . The debug info can easily be fixed up in a hex editor, I'm struggling to find where dmd is outputting the incorrect info though. In the __debug_info section the abbrev_offset field is being set to the incorrect value. The workaround is to change it to zero in a hex editor, this is not the correct solution though, the correct offset needs to be inserted. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

http://d.puremagic.com/issues/show_bug.cgi?id=4154 --- Comment #7 from Robert Clipsham rob...@octarineparrot.com 2011-06-04 01:18:01 BST --- Actually, removing the offset seems to be the correct solution - it's what both gcc and clang do on OS X (despite it being contrary to what the DWARF spec states). I'll put together a pull request now. Another odd side effect seems to be that no debug info ends up in the resulting binary (only the object files), but again, this seems to be consistent with gcc and clang's output when using -g. I recall reading somewhere that Mach-O uses a separate file for debug information, it could be related to this. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Unfortunately dsymutil exploded violently when I tried to get it working, so I didn't add it into dmd's builder. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
