In C++, you get essentially the same thing from g++:
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../../lib/crt1.o: In function
`_start':
(.text+0x20): undefined reference to `main'
collect2: ld returned 1 exit status
Lot of people come here because they want a compiler+language better than C++
:-)
If you compile this:
void main() {
writeln("Hello world");
}
Since some time dmd shows an error fit for D newbies:
test.d(2): Error: 'writeln' is not defined, perhaps you need to import
std.stdio; ?
Probably many Python/JS/Perl/PHP/etc programmers that may want to try D don't
know what a linker is. When they want to develop a large multi-module D program
they must know something about how a linker works. But D has to scale down to
smaller programs too, where there are only one or very few modules, written by
not experts of C-class languages. In this situation more readable error
messages, produced by dmd that catches a basic error before the linker, is
probably useful.
Couldn't have written this one better ;-)
