Makefile references port.c.o correctly. Any ideas?

Thanks

Hi Sumit!

I really have no idea what's going on here.

memicmp() should not be called on FreeBSD. Instead an implementation is provided in dmd/root.c, line 793.

HtmlNamedEntity is defined in dmd2/entity.c. It looks like the entire file is missing.

How do you compile ldc?

Stupidly it would appear. Had cmake trying to build shared. All good now, sorry about the noise

Yeah, shared libs do not work yet.

Made more progress with the build and install but now I am seeing issues with linking libphobos.

import std.stdio;

void main() {
writeln("hello");
}


Fails to link on FreeBSD with

I see it here:

Has druntime linked correctly in the phobos build? Would really like some guidance on how to debug this further.

Thanks

That should read "would really appreciate some guidance on how to debug this further" ;-).

Early mornings eh...
