Running the latest 2.061 compiler on my Mac, I have a simple program that
imports std.stdio, does a bit of math and then writeln's a result. It compiles
and runs fine on my Linux box. On the Mac, I'm getting:
dmd -w -O -inline -noboundscheck p001.d
Undefined symbols for architecture x86_64:
"_D4core5bitop3bsrFNaNbmZi", referenced from:
_D3std5array17__T8popFrontTAyaZ8popFrontFNaNbNeKAyaZv in p001.o
_D3std5array16__T8popFrontTAaZ8popFrontFNaNbNeKAaZv in p001.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
Demangling these:
_D4core5bitop3bsrFNaNbmZi
pure nothrow int core.bitop.bsr(ulong)
_D3std5array17__T8popFrontTAyaZ8popFrontFNaNbNeKAyaZv
pure nothrow @trusted void
std.array.popFront!(immutable(char)[]).popFront(ref immutable(char)[])
_D3std5array16__T8popFrontTAaZ8popFrontFNaNbNeKAaZv
pure nothrow @trusted void std.array.popFront!(char[]).popFront(ref char[])
Interestingly, I'm not even calling using popFront directly in the program.
It was working with a previous version of the compiler (2.060). I'd installed
the latest since I was getting issues with a program that actually uses
popFront and thought perhaps the newer version would address this issue. It
appears there be dragons in this area.
Yell if there's additional information you require. A skeleton of the program
I have is:
import std.stdio;
immutable auto N = 10;
auto func(int n) {
auto d = N / n;
return n * d * (d + 1)/2;
}
void main() {
writeln(func(2)+func(7)-func(14));
}
