Yo --
I'm trying to compile the following source:
int main(char[][] args)
{
return 0;
}
And I get a couple of unresolved externals:
$ dmd main.d
gcc main.o -o main -lphobos -lpthread -lm -Xlinker -L/opt/dmd/lib
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/../../../crt1.o(.text+0x18): In
function `_start':
: undefined reference to `main'
main.o(.gnu.linkonce.t_assert_4main+0x11): In function `_assert_4main':
: undefined reference to `_d_assert'
collect2: ld returned 1 exit status
As far as I can tell, I'm following the documentation pretty closely. Does
anyone know what I'm doing wrong?

It looks like libphobos.a is not being found. Did you put it in /usr/lib ?

you need something like: dmd main.d -I~/dmd/src/phobos

John <John_member pathlink.com> I've got that in my dmd.conf: [Environment] DFLAGS=-I/opt/dmd/src/phobos -L-L/opt/dmd/lib I don't think the problem is of the nature 'can't find some file.' It gets to the linking stage, and when it throws everything together, there are some unresolved externals. If it couldn't find some file I'm sure it would complain specifically about that. -- John In article <pan.2004.02.09.23.31.43.879205 yahoo.ca>, Ant says...On Mon, 09 Feb 2004 23:16:45 +0000, John wrote:It's finding it -- it would say 'could not find -lphobos' when it couldn't.

This is what happens when I change dmd.conf so that it can no longer find libphobos.a: /usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/../../../../i686-pc-linux-gnu/bin/ld: cannot find -lphobos So I'm rather positive that it's finding libphobos.a normally... -- John In article <c0a4p0$64a$1 digitaldaemon.com>, Walter says...Those unresolved symbols are in libphobos.a.

Okay, I think I've got at least some part of it fixed. Apparently, when linking with static libraries (I'm pretty sure dynamic libraries don't have this problem), the order in which they're given to the linker is important. By default, D executes gcc main.o -o main -lphobos -lpthread -lm -Xlinker -L/opt/dmd/lib Whereas libphobos needs to be placed before main.o. When I run GCC myself and rearrange things to look like gcc -L/opt/dmd/lib -lphobos -lpthread -lm -Xlinker main.o -o main Then I'm down to one unresolved external: main.o(.gnu.linkonce.t_assert_4main+0x11): In function `_assert_4main': : undefined reference to `_d_assert' So it looks like now it's finding main -- but obviously I'm still having trouble with _d_assert. Is this also part of libphobos? Is there a debug library I need to link against to get _d_assert?

_d_assert is defined by module std.asserterror, and it should be in the
library.
(To find where names are defined, the following is very handy:
cd \dmd\src\phobos
grep -r d_assert *.d
)

Walter wrote:_d_assert is defined by module std.asserterror, and it should be in the library. (To find where names are defined, the following is very handy: cd \dmd\src\phobos grep -r d_assert *.d )
Just a minor clarification: the command should be grep -r d_assert . With -r (recurse), grep takes directories as arguments. You can pass it files as arguments, but it won't recurse into directories unles you give them on the command line. Russ

Linux grep does work like that, you're right, but the win32 grep that I wrote works like the former <g>. In any case, grep is an underappreciated utility.

One more addition grep -rn d_assert . gives line numbers also very handy :).
