I ran across this on RH 7.2, gcc 2.96 (same as you Walter)

I get "undefined reference" errors when I compile the following code:



int main(char[][] argv)
{
  switch(argv[0])
  {
  case "asdf":
  case "jkl":
    return 1;

  case "qwerty":
    return 2;

  default:
    return 0;
  }
}



I compiled it with:
    dmd -c dmd_bug2
    cc -lphobos -lpthread dmd_bug2.o -o dmd_bug2

What is the undefined reference to?

_d_switch_string and _d_array_bounds.

I originally came across this error when I tried to link my large app (ported from DLI) and got to the linking phase.  In that larger app, I have lots (100 or more) of such errors, many of which seem to be link problems to phobos.  Some other ones seem to be internally implemented functions, like _aaIn _aaGet _init_TypeInfo_Aa and such.

I don't get it. They're in the library, and they're found on my system.

I'm confused, too.  I can find the symbols with grep.  I do get "bad
relocation symbol" warnings, as well.  (sigh)  I guess I'll copy it all (by
hand, unfortunately).

On RH7.2, gcc 2.96, I get these errors:



dmd_bug2.o: In function '_Dmain':
dmd_bug2.o(.gnu.linkonce.t_dmain+0x30): undefined reference to
'_d_switch_string'
dmd_bug2.o: In function '_array_dmd_bug2':
dmd_bug2.o(.gnu.linkonce.t_array_dmd_bug2+0x14): undefined reference to
'_d_array_bounds'
collect2: ld returned 1 exit status



On RH9, gcc 3.2.2, I also get this error (first, before the others):



/usr/bin/ld: /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libphobos.a(gc.o): bad relocation section name '.rel.gnu.linkonce.t_d_new? '




BTW, /etc/dmd.conf doesn't seem to work for me so far...so I'm having to add -I<phobosPath> to my dmd commands.

I've tried to build a new libphobos.a from the sources, t osee if that would clear up the problem.  I ran into a couple of problems.

* FIXED: the makefile mentions "deh2.d", which doesn't exist, so I deleted it
* FIXED: the makefile has the wrong location for DMD, so I changed that to just
"dmd"
* COULDN'T FIX: outbuffer.d calls vsnprintf, which doesn't seem to be defined in
any source file I can find

I'm really appreciating your continued hard work, Walter. Russ

All right, but it never tries to add it to libphobos.a!

Ok.

vnsprintf is part of the C runtime library. It should be in c.stdio.d

Thanks!

Ok, I've been stepping through this thing, trying to link something together. Walter, is this src/phobos the directory you built libphobos.a from?  I'm having a heck of a time trying to get things to work.

Right now, I'm stuck on deh.c, line 528.  I'm getting a few errors.  First of all, gcc seems to gripe about that __stdcall modifier; I tried commenting it out and got a little further, but I don't know if we need to leave it in.

Then, on line 535, I get "'_EBP' undeclared"

Any fixes for these?

Thanks again,
    Russ

Oops, I think that's the wrong file. I'll try & get the right one.
