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

_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. -- The Villagers are Online! villagersonline.com .[ (the fox.(quick,brown)) jumped.over(the dog.lazy) ] .[ (a version.of(English).(precise.more)) is(possible) ] ?[ you want.to(help(develop(it))) ]

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).

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.

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

All right, but it never tries to add it to libphobos.a!
* FIXED: the makefile has the wrong location for DMD, so I changed that to
just
"dmd"
Ok.
* COULDN'T FIX: outbuffer.d calls vsnprintf, which doesn't seem to be
defined in
any source file I can find
vnsprintf is part of the C runtime library. It should be in c.stdio.d
I'm really appreciating your continued hard work, Walter.
Thanks!
