Re: linker @ meaning and how to compile static libs

Re: Struct inheritance
So why not just use classes? I've understood it as there may be a performance gain by using structs over classes, and in my program Point and Coordinate are used heavily. The other big difference is value vs. reference type. You can use alias this to achieve something like struct inheritance.

Re: Casting the Result of splitter() into a string array
If you want to convert a range to an array, use std.array.array This is a constant source of confusion and it also is a crappy design to use a function in a totally different module for this purpose imho. Can't these Result types get an eval() method and/or be made implicitly convertible to an array where appropriate? The C++ matrix library Eigen uses this approach and it works out fantastically. a*b returns an object representing this expression. If I do want to use this I write 'auto c=a*b;'. If I want the result I can explicitly use its eval() method (which is especially useful inside a bigger expression) or something like 'Matrix c=a*b;' which also evaluates the expression.

Re: Link with C static library
Should I change my C compiler? Or, there is another way to covert static library from COFF to OMF?? coff2omf should work, but unfortunately it isn't free. coffimplib is free, but can only convert import libraries. You may try to use objconv: http://www.agner.org/optimize/#objconv Though it doesn't work in all cases. Compiling with dmc solves the issue but is often tedious cause headers are different etc. Easiest solution if you can't do it statically is to use dlls.
Re: Link with C static library
I used it to convert static library, and it says the input library is not import library. That's coffimplib. coff2omf is in the Extended Utilities Package which is sold for 15$. Many existing C libraries are not written as dynamic libraries. Some C libraries can be compiled as DLL, but in performance critical application, such as games, they must use static link to increase performance. I hope there is a good solution for linking C static libraries. Well maybe Walter will give away coff2omf (and maybe obj2asm too) for free some day to solve this problematic situation. As I said, either you buy coff2omf, try objconv or compile with dmc.

Re: template magic
2. What is the reason for Phobos defining param funcs as template params? Correct me if I'm wrong but there's no way to pass an arbitrary function to a function in a type-safe way. If you use pointers and casts you can't check if the passed function meets certain requirements (parameters, return type, attributes, etc.) 3. What is the meaning of 'alias f'? How does it work? This is a totally enigmatic feature for me. Seems it allows placing anything of any type as template param. http://digitalmars.com/d/2.0/template.html#TemplateAliasParameter It allows you to pass any D symbol. As the name already suggests, think of it as being a template-local alias to a symbol passed in the instantiation (but note that you can also pass literals as arguments to alias parameters).

How do you not pass them in a safe manner? If you are casting things, of course you don't get type safety. Yep, I was talking about non-template functions. Only way to pass an arbitrary function is via void*

Use derelict2 from svn and xfBuild. Then you just need to tell dmd where derelict is via -I I'd have thought that, since D interfaces so well with C, just using C libraries wouldn't require specific wrapper libraries, but it seems an automated method for converting C headers to D isn't currently possible? Derelict does a lot more, it hides all the nasty handling of different OpenGL versions that might be installed along with extension loading. To my knowledge there are several tools to convert C headers to D import modules: - htod, which is crappy. Since it's based on dmc, it nearly always complains about header files and the like; it doesn't translate preprocessor conditional compilation to versions or static if and almost always messes something up (const or whatever, can't remember) - SWIG, which I haven't tried yet for that purpose. But I think it will have the same problem with preprocessor conditional compilation. - c2d, don't know how good it works: http://dsource.org/projects/visuald/browser/trunk/c2d - bcd, which is obviously abandoned: http://www.dsource.org/projects/bcd

Since you are doing a ~= it probably tries to alter that value and crashes.
You should use something like SDL_LoadBMP(cast(char*)(path ~ \0)) if you
really wanted to convert it manually.

Good luck with that. DLLs are no problem but static libraries are another story. objconv has never done the job for me. I'm surprised that it worked in your test. And compiling the code with dmc is a real PITA. Maybe dmd will finally switch to COFF output in the course of 64Bit transition but even then the 2 different compilers might generate incompatible code. There is a linker named Unilink though, which is reportedly able to link OMF and COFF files out of the box. But it doesn't even have a homepage, only an ftp server that's hard to find. Plus it's closed source so you can't assess whether it will continue to be developed, if it becomes commercial one day etc. For what it's worth, using GDC and GCC/MingW (TDM), I was able to build and debug a D/C/C++ mixed executable. I had to use GDB (though WinGDB works just dandy), but the downside is I'm not using Visual D (unless Visual D supports GDC??), nor DMD. DMD seems that it would be more supported and stable right now than GDC, which seems to play catch up. I worry that, as a user of GDC, hitting a compiler bug, would take longer to get an official fix for, than it would for DMD. GDC shares the frontend with dmd, so it will benefit from any FE bug fixed there. Regarding the glue code, it is currently maintained by Iain alone. He tends to be quite active though.

Re: how to reduce a debug symbol error?
First: are you compiling *all* modules with -gc rather than -g? Ah ok, somehow I was mislead into thinking that the gdb patches allow you to use -g. It works now though line numbers are more messed up than I'm used to from cv2pdb + VS. There I only have the usual problems with mixins but here it even jumps around senselessly if I just do a step over. Don't know if this has to do with -gc or Descent. To do that, I recommend you unleash DustMite on your source: https://github.com/CyberShadow/DustMite. You'll need a script that can test for the bug too, you can pass a command file to gdb and grep for the relevant failure, alternatively if you can get the failure when using dwarfdump/objdump that may be easier. Yeah need to test that tool soon.
Re: Dynamic multidimensional arrays
If you want it to by dynamic all the way, you need to put the dimensions in the parens like above. Personally, I _never_ put them in the brackets, even when the dynamic array has just one dimension. It's just simpler to always put them in the parens and not worry about it. Maybe we should force the parens approach even for one dimension. At least dmd should give better diagnostics. It's damn hard to even find that syntax in the docs.
Re: translate a macro to D

The macro is supposed to define some constants. Just turn it into a function. If you assign it to an enum or use it as an initializer for global immutables it should be evaluated at compile-time.
Re: Declaring a D pointer to a C function
You should declare the function pointer without the extern(C).
Example:
alias int function(void* test) FTInitFunc;
extern(C) int foo(void* test){ }
FTInitFunc foo_ptr = foo;
This worked for me.
That's a bug.
template instance cannot use local 'f' as parameter to non-global template
Is this a bug? If not, how do you make it work?
void h() {}
class Bla
{
mixin wrap!h;
}
mixin template wrap(alias f)
{
void blub(alias g = f)()
{
}
}
void main()
{
Bla b = new Bla();
b.blub();
}

Re: Running DMD tests
Am 13.06.2011, 23:55 Uhr, schrieb Peter Alexander peter.alexander...@gmail.com: I'm trying to run the test suite for DMD, but I'm running into issues. Do I need to set up my environment differently to run dmd in development? How can I get around this? To quote IRC: In theory it's simple: go to dmd/test and run make. In practice you need to have druntime and phobos installed at the right places. I think if you clone dmd, druntime, and phobos and put them all in the same directory, then you build dmd, druntime, and phobos, then you should be able to run the test suite. you also need to have a dmd.conf that's not included with the suite : Ah, yeah, true. And since I remember I made my dmd.conf point to those places, maybe you don't need to have druntime and phobos there after all. But it's still a good idea to be able to get non-release druntime (and to some extent phobos) when playing with non-release versions of DMD.

Re: Declaring a D pointer to a C function
Is this going to be fixed any time soon? Allowing callbacks with D calling convention where a C callback is expected should be an error, and this is like the 10th time I've ran into this bug. http://d.puremagic.com/issues/show_bug.cgi?id=3797

As a workaround, is there a reason you need blub to be parameterized? I
mean, f is already part of the template.
Yep, a default function is passed to wrap and in most cases blub just
calls that one.
But sometimes I need blub to use a function other than the default one.

Don't know it this is the right answer or a possible bug but it does the
trick:
void h() { import std.stdio; write(h()); }
class Bla

mixin wrap!h;

mixin template wrap(alias f)
{
void blub(typeof(f) g = f)

Bla b = new Bla();

Thanks!
Unfortunately it doesn't work with more complex functions:
Error: arithmetic/string type expected for value-parameter, not cl_errcode
C function(cl_program program, uint param_name, ulong param_value_size,
void* param_value, ulong* param_value_size_ret)
Re: template instance cannot use local 'f' as parameter to non-global template
I've seen this error before... *searches memory and old code* Here you go: http://d.puremagic.com/issues/show_bug.cgi?id=3051 I think this is yet another issue. The inner template argument is not something on the stack but it is a template argument.

When downloading the pre-build libraries from the website I link them in using: You save yourself a lot of hassle if you just stick with dlls on Windoze. Converting prebuilt libs has never really worked for me. And compiling them with dmc is a nightmare. But creating an import library from a dll with implib worked really well so far no matter how the code was compiled.
