Hi there,

Is this a problem with gcc3.2, or with the dli sources?  I've heard there's problems in libc with gcc3.2 relating to errno, but didn't really understand the thread :-)

gilescpc2# make
make -C phobos
make[1]: Entering directory `/usr/local/src/dli-0.1.2/phobos'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/usr/local/src/dli-0.1.2/phobos'
./dli test.d -unittest
phobos/libphobos.so: undefined reference to `errno'
collect2: ld returned 1 exit status
./test hello arguments

make: *** [testfoo] Error 127

Since errno is implemented as a macro on many C compiler systems, referencing "errno" from D code will rarely work. Therefore, use instead the function getErrno() which is defined in phobos/errno.c, which essentially translates the macro into something usable by D.

**I** didn't use errno! :-)  It doesn't appear in the source either.. it appears to be a linker error when compiling with dli itself - even if I try to compile "hello_world.d" without referencing 'errno' at all, it pops up with a complaint about errno.  See the original comment - I got the error immediately after typing "make" within the dli sources.

eg:

gilescpc2# cat hello_world.d
import string;

int main(char[][] args)
{
   printf("Hello world!\n");
   return 0;
}

gilescpc2# ./dli hello_world.d
phobos/libphobos.so: undefined reference to `errno'
collect2: ld returned 1 exit status
gilescpc2# pwd
/usr/local/src/dli-0.1.2

I suggest switching to the DMD linux version.

ah.. now i'm getting results.. thanks :-)

Quick question - how does one build it from source?  There don't appear to be any makefiles or anything.  I'd be interested in creating a gentoo package out of it.

So far as I know, Walter has released DMD Linux in binary form only (except for the front end?).  I think a gentoo ebuild would be great too, but it would have to be a binary only package (which is completely feasible).

A future Redhat RPM and Gentoo ebuild (and perhaps other distribution packages) would be a great form of publicity for the D language, I think.  I really hope this happens soon.

By the way, has anyone tried DMD Linux on FreeBSD yet (using the linux compatibility layer)?

Later,

John

That's correct.

I  fully support the D community integrating D in with GCC!

Not yet that I know of.

I think he really met packaging up your binary etc as a RPM for ease of
installation.
RPM is one of the standard install techniques for Linux, it is separate from GCC
etc.  For an Alpha/Beta product I'm not sure if this is necessary, I found DMD
linux to be very easy to get working.
If someday in the future, you sell a commercial DMD Linux distribution you would
really need to address this. I'm sure many of the smart folks in this forum
would be glad to give their assistance with this.

Ok, I see.
