simple dub question - avoiding creating a vibed project
Hi.

sample code extract from the website).

Re: What exactly shared means?
On Saturday, 3 January 2015 at 23:11:08 UTC, Jonathan M Davis via Digitalmars-d-learn wrote: Ideally, you would never cast away shared, and it would be cast away for you by the compiler in sections of code where it can guarantee that it's safe to do so (that was part of the idea behind synchronized classes). But that's incredibly difficult to do, particularly in a useful way, so we don't currently have it. And yes, that sucks, and we definitely want to fix it, but I still think that it's far better than having everything be shared by default like you get in languages like C++ and Java. Efficient automatic synchronization is difficult, yes. You can try to tie groups of entities to a lock, but that will only work in some scenarios. To me it sounds like having everything shared by default is the most conservative (safest) approach, and that it would make sense to put restrictions on parameters when you need more performance. If D's approach should make sense the compiler would allowed to elide atomics on members of an object the reference to the object is not marked as shared. That can easily go horribly wrong. I am also not overly happy with D making TLS default. That means new threads instantiate a lot of unused memory if the workload is heterogeneous (different threads do different type of work). TLS only make sense for things that all threads need.

This is what's known as cross compiling and is not currently supported by DMD at this time. Any alternatives? You might be able to lightly tweak ldc to do it: I was able to cross-compile druntime/phobos, their unit tests, and some small sample apps on a linux/x86 host to run on a linux/ARM target. The problem isn't really the D compiler so much as the other needed tools and environment. Dmd and the other D compilers are automatically configured to use your system linker and link against the system's C standard library. Well, optlink or the Microsoft linker on Windows don't know how to link for linux or OS X! So you have to set up linkers and C libraries for every other OS you want to build for on Windows. It's possible: the Android NDK can be installed on Windows with Cygwin and compile C/C++ code for the various Android architectures. But none of the D compilers have gone to all the trouble to provide that cross-compiling support out of the box for all the various OSs they support. It's easier to just run each OS in a VM on top of Windows, as Colin said.

Conditional functions
Is it possible to use static if in a template structure to have
some member functions only for specific types?
E.g.:
struct Foo(T)
{
...
T get() { ... }
static if(isMutable!T)
{
void set(T x) { ... }
}

Well, if you don't like the choice of TLS by default, then you're going to be unhappy with shared and its related issues regardless. Personally, I think that having TLS be the default is a fantastic improvement over C++ and that it results in much cleaner and safer code, especially since the vast majority of code only lives on one thread anyway if you're dealing with threads cleanly. But it's definitely true that what we're up to is an experiment in how to handle TLS and shared storage, and by no means have we gotten it perfect. - Jonathan M Davis

What is wrong?
You druntime installation is bad due to some cruft left from a
previous
install (the installer obviously needs some work). If you used
an installer,
then uninstall dmd, make sure that it's completely removed, and
then reinstall
it.
If you installed it manually, then make sure that you blow away
druntime's
import directory and then restore it with the current version
of those files.

I am having this issue now. What else would I need to do other
than uninstall and reinstall D on Windows to get it working? I
tried that and it's not fixed it. Importing std.random in my own
module which is in the project directory fails to find the symbol
while importing std.algorithm works fine. Importing std.random in
main.d works fine as well.
