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?

Regards

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...
