Can't run unit tests on Win7 64-bit?
I have a super simple D file that looks like this:
unittest{
import std.stdio;
writeln("hello");
}
On OSX Mavericks I run "rdmd --main -unittest test.d" and I get a
nice "hello" and everything is well.
On Win7 64-bit I run "> rdmd --main -unittest test.d" and rdmd
seems to hang. It never outputs "hello", and it doesn't terminate.
Is this a mistake on my part? Or just an annoying bug?

It's true that it *can* be used to check that the unittests cover all cases, but that's far from its only use. - Even if checking unittests were its only *practical* use, it would be arbitrary to program in a restriction explicitly. I believe that the _common_ use case for -cov is to check the coverage of your unit tests, in which case you'd also need to use -unittest (that's what is _normally_ meant when talking about code coverage). However, there's nothing stopping you from using it when running your program normally. Moreover, does DMD have a Win64 (either runs on or compiles for) version? Or is it just the normal Win32 version, running on your 64-bit system? It would be useful if we could find out the circumstances in which this bug bites. As far dmd itself goes, only a 32-bit binary exists, and Walter has no plans to create 64-bit version. In terms of compiling with dmd, Linux got 64-bit compilation (when you use -m64) with the latest release, but there are a number of things which will need to be sorted out before dmd will be able to compile 64-bit programs on Windows (including having a 64-bit linker). - Jonathan M Davis

Would you care to enlighten the rest of us on what code you were using that requires those extra switches? Yeah. That's weird. If you want to run the unit tests, you use -unittest. If you want code coverage, you use -unittest and -cov. If you want documentation, you use -D, but it has no relation to -unittest and -cov, and it isn't necessarily a good idea to build your code with -D normally because of the effects that version(D_Ddoc) could have on your code, and there are a number places in druntime and Phobos which won't result in valid code if you build with -D (until it's fixed in the next release so that druntime and Phobos' documentation is versioned with version(StdDoc) instead). So, _needing_ all three of those flags seems just plain wrong. If you're using -cov, you probably want -unittest, but -D has no relation to the others and shouldn't be necessary for _anything_ other than generating documentation. - Jonathan M Davis

I am running the dmd2 compiler on my Win7 64 bit machine and everything appears to work except the -cov switch. i cannot seem to generate a .lst file. any ideas? thanks dan mcleran

never mind, i got it. i had to pass the switches: -D -unittest -cov life is hard. it's even harder when you're dumb.
