With the caveats that the linked post is almost 14 years old, I 
can't try this command myself, and the ldc solution is probably 
preferable if you can get it to work - if you want to compile 
with dmd and use the strip command, this might help you (the OP

https://forum.juce.com/t/how-to-build-dylib-exporting-only-wanted-symbols/2180

He suggests doing:

strip -u -r -s FILE_CONTAINING_EXPORTS_LIST MY_DYLIB.dylib


It looks straight forward that way - thx

You *might* be able to compile with 
--link-defaultlib-shared=false to use the static 
phobos+druntime... but with shared libs it prefers shared and 
might not allow this. Probably worth a try.


Otherwise I'd try to just add the phobos so to your sandbox 
somehow. or the rpath set to current directory and putting them 
in your correct directory may also work. I don't know how that 
works on Mac but on Linux it is passing... `-L-rpath -L.` or 
something like that when compiling... I can't find my notes on 
this but something like that.


I think figuring out how to add phobos to the sandbox is probably 
the best option as I'm sure it won't be the last dylib I need to 
load.


Anyone else done this? Pointers welcome.

Thx that's really helpful.

I've hit a snag with LDC. After serveral hours of searching and 
reading I think it's coming down to sandboxing and needing to 
deploy libraries in a place that excel can find them.


The library DMD creates just references 
/usr/lib/libSystem.B.dylib and Excel can load my dylib.


LDC on the other hand additionally references:

@rpath/libphobos2-ldc-shared.95.dylib (compatibility version 
95.0.0, current version 2.0.95)
@rpath/libdruntime-ldc-shared.95.dylib (compatibility version 
95.0.0, current version 2.0.95)


So Excel complains that it can't load my library - presumably 
because libphobos2 and libdruntime are not in the sandbox.ly


Can anyone (either tell me how to fix this) or give me pointers 
pls? (I'm current reading up on DYLD_LIBRARY_PATH (shouldn't use 
that), sandboxing on Mac, and rpaths)


I suppose a solution that allows the additional libraries to be 
put in a subdirectory of my library would be idea as then I can 
deploy that within the sandbox.

Is it possible to suppress standard lib and dlang symbols in dylib (macos)

2021-03-11 Thread David via Digitalmars-d-learn
I thought it would be fun to convert some old C++/C quant utils 
to D. I'm starting with a simple library that I call from vba in 
Excel on macos:



module xlutils;

import core.stdc.string : strlen, strcpy;
//import std.conv : to;
//import std.string : toStringz;
import core.stdc.stdlib : malloc, free;

extern (C) double addDD_D(double a, double b) {return a + b;}
...


which results in:

nm -gU libxlutils.dylib
3f10 S __D7xlutils12__ModuleInfoZ
3e44 T _addDD_D
3ebc T _addrC
3e84 T _freeP
3e9c T _strcpyCC
3e6c T _strlenC_L


If I import `to` and `toStringz` I get more symbols than will fit 
in my shell output. E.g.


000318bc T

Hi, yes, good question, yes I did - my first cut using the

myself.


So some questions I'm asking myself -

What people's heuristics for switching methods say from, some 
sort of pool to another approach - e.g. linked list of pages? At 
the page level does a bitmap allocator make more sense?


Knuth (it seems) was under the impression that a third of memory 
is wasted by fragmentation, aka the 50% rule - that doesn't seem 
likely, does anyone measure these things?


How does one go about choosing a set of pool sizes?

Given that virtual pages are not necessarily physically 
contiguous are some of the considerations that inspired the buddy 
system no longer relevant.


I should also say I'm aiming for a single thread longish running 
process (one +  working days) that I anticipate could use a good 
chunk say 100GB or so on occasion but I'd like to be more 
efficient than java in terms of memory reuse - past experience 
was I had to reboot my workstation a few times a day as it did 
something really horrible (I don't know what).

Re: Address of an array

2016-10-27 Thread David via Digitalmars-d-learn

A dynamic array looks something kind of like this:

struct DynamicArray(T)
{
size_t length;
T* ptr;
}

So, if you take the address of a dynamic array, you're 
basically taking the address of a struct on the stack, whereas 
the address in ptr is the address in memory where the data is 
(be it GC-allocated memory, malloc-ed memory, or a static array 
on the stack somewhere).


Similarly, if you have a class reference, and you take its 
address, you're taking the address of the reference, not the 
class object that it points to. e.g.


class MyClass
{
string foo;
}

MyClass mc;
auto addr = 

addr is the address of mc on the stack, whereas mc itself is 
null.

Game Development Using D

2016-05-21 Thread David via Digitalmars-d-learn

Hi,

I want to try to create a game using D. I'm a complete newbie 
though (other than having C/C++ experience). Where would I start? 
Does D have an openGL binding? I am assuming I'll need to 
leverage a good amount C APIs? Any list of these that would be 
useful it a game setting?


Obviously this all depends on *how* much work I want to do. 
Ideally, I'd like a collection of tools that will get me roughly 
the equivalent of what XNA provides.


Re: Programming a Game in D? :D

2014-08-31 Thread David via Digitalmars-d-learn

Hi,
About 2 month ago I started learning modding for minecraft with 
the Forge API
I was reading through a lot of classes of minecraft and even no 
it might not seem like, I learned a freking lot about how games 
work and stuff and improved my programming skill a lot (Yes for 
Java but also overall)
So now, I want to come back to my own game with a lot of 
questions :P
So first of all, I'm not sure if D is really the best choice for 
me. Since its just pretty hard for begginers like me without any 
tutorials and anything to come up with a game. Then what language 
should it be? It should have a big community around and be a good 
language for games (fast) and it should not be called C++.
And I know you told me it would be a better idea to get going 
first with easier tools like gamemaker or something like that, 
but I seriously don't want to come up with something big anyway 
and if i fail completly I don't mind.
And finally, (now thats going far away from the actual point and 
maybe thats even the wrong forum for that) how is wrapping 
working? lets say I wrote a method methodA in Java in ClassA and 
wanted to use MethodA in D, how would I go about doing this?

Hi, not too sure if there's still someone reading this post, but 
i do have another question. So, I heared so much good stuff about 
D, it's powerfull, fast the syntax is nice, but well, why is D 
actually not used for common games yet? (I mean I know about some 
smaller projects, but nothing big)

Hi David,

Learning programming, learning D and learning 3D are 3 
significant endeavours.
You might want to begin with http://www.basic4gl.net/ which 
will get you going with 3D, quite a topic in itself.

Then learn D regardless :)


So, I'v used Blender for a half year or sth. and I think I can 
make a little area :)
As far as I know, I do now need a graphic and physics engines, 
1 of the graphic APIs and for sure my programming stuff and 
here I'm stuck :D


And I still can't install Mono-D :( if I try I just get a 
whole bunch of errors that any packages couldn't be found, 
don't know if I'm doing sth. wrong

(I probably do :P)


I would STRONGLY advise to go with a ready engine like Unity.

You still have to learn a lot before you  will have just 
building blocks to create a game like loading and rendering 3D 
models, a gameplay framework etc etc.


Start with Unity, lean how to make a game there. Learn how to 
programm gameplay there and after that, when you see what is 
needed before even being able to make a game, only then try to 
make things from scratch. Use C# in Unity too as it is similar 
to D so you will have easier transition when necessary.


Ok, now I just wonder wich Engine. (I know everybody hates the
discussion about the best engine.) CryEngine, UDK, Unity or a
less known Engine?

I'll be honest, perhaps I risk being misunderstood, but the 
questions you are asking denote a lack of even basic knowledge 
about the subject, so I really think you should do some good 
amount of research before even trying to write something on 
your own.




Well, I really don't have a lot of knowledge but I don't know 
where to start.
The Problem is just that there is sooo much stuff in the internet 
and it's kinda hard to get some knowledge.


Have you tried at least some free tools that allow you to 
script stuff and have simple stuff displayed on screen? I'm 
talking about stuff like Construct 2, GameMaker, RPGMaker, 
zGameEditor... even map editors like the ones from Blizzard 
(WarCraft 3 : TFT or StarCraft 2)?


So, i made a very little game with delphi Genesis3D and an Editor 
i don't remember about 2 years ago, but i don't know if i really 
knew what i was doing there :P

actually not. you don't even need to register at all. just go 
to http://monodevelop.com and get ur XS without all this fancy 
mobile stuff.


So I installed that Xamarin studio (hope i had to), what to do 
with the mono D thing now?

don't know hot to install it :P

Ok so I installed DDT for eclipse now but have a problem :D
First the imports are changed, std.studio is now std.stdio (or 
its something completly else)
And if I try to run the file now it says that the exe file of my 
file doesn't exsist wich I actully thought I creat by clicking on 
run?

In Java it was just pressing run.. :/

Programming a Game in D? :D

2014-05-22 Thread David via Digitalmars-d-learn
Hey, I'm really new to D, and pretty new to programming overall 
too,
But I want to make a 3d Game, (just sth. small). I really like D 
and want to do it in D, but in the Internet there is no shit 
about programming a game in D ^^

Is there any engine written in D?
For example the CryEngine is for C++, so I would have to write a 
wrapper?
So, how do I write a wrapper? I would need a wrapper for DirectX 
too right?

Are there any wrappers ore Engines for D i can use?
btw. I know I dont write that in 1 day ^^
Are there any tutorials or sth. on Programming a Game in D?
S I just wanna come as far to have a little Cube where i 
can run around on with a few phisics :) so just the startup to 
load a world and so on

Thanks in advance :)
And sry my english sucks :D


Re: DMD Deimos || GDC Deimos?

 I'd like to use GLFW from Deimos, but I couldn't get it to work (DMD
 said it cannot use libglfw.a) and I've read somewhere that only GDC can
 use these DLLs directly (with a D header, but that's still better than
 hooking the methods). So do I need GDC for that or not? And would you
 actually recommend it?
 
 On a side note, getting GDC to work is a bitch. I had to copy around
 several DLLs (like libiconv-2.dll) and it's now working only with the
 libgcc_s_sjlj-1.dll copied right next to my application's exe. What am I
 doing wrong?
 
 This is really frustrating :/



I have a 10 month old glfw3.dll

https://github.com/Dav1dde/BraLa/tree/master/lib/win

Since glfw didnt change much (that was already at release), this is
probably enough for you. Simply pass the glfw3.lib to the compiler and
make sure glfw3.dll is reachable in runtime.

But you can also build your own using cygwin (that's how I made it) and
use implib for format conversion.
