digitalmars.D.learn - Linking C and D
- monarch_dodra (31/31) Feb 27 2013 I'm trying to get the hello world of cross compiling working:
- Andrej Mitrovic (10/18) Feb 27 2013 The short story is you can't link GCC and DMD object files on
- monarch_dodra (3/21) Feb 27 2013 Thanks.
- Alexandr Druzhinin (5/19) Feb 27 2013 Under Windows I use dmc + dmd and gdc + gcc - all these combinations
- monarch_dodra (17/42) Feb 27 2013 TY. dmc works. Unfortunatly, I'm actually doing this to compile
- Alexandr Druzhinin (3/9) Feb 27 2013 IIRC, there is such switch, but I can't remember it, may be
- monarch_dodra (4/20) Feb 27 2013 I found a couple posts about that, but it doesn't seem to do
- jerro (4/25) Feb 27 2013 You could try using GDC and GCC instead. There are MinGW GDC
- Michael (6/6) Feb 27 2013 With Dmd you can use dmc directly.
- Michael (4/4) Feb 27 2013 Also C runtime can be statically compiled with your c/dll
I'm trying to get the hello world of cross compiling working:
main.d
//----
extern (C) void foo();
void main()
{
foo();
}
//----
foo.c
//----
#include <stdio.h>
void foo()
{
printf("hello world");
}
//----
I can't seem to get the executable to link correctly.
I'm using gcc and dmd on windows.
I'm building foo.c with:
gcc -c foo.c -o foo.obj
Then I build my exe with:
dmd foo.obj main.d
But I get:
OPTLINK (R) for Win32 Release 8.00.12

...Help ?

Unfortunatly, I'm actually doing this to compile "font" files into my D project. They can reach 2_000_000 lines, and weight in at over 100Mo of code. dmc seems to choke on these: //---- nbytes = 102000, ph_maxsize = 65520 Internal error: ph.c 1854 //---- dmc seems to start choking when my font files start to reach about 15 Mo. I suppose there's a switch somewhere, but I've never used dmc before, so all the switches are unknown to me. I guess I'll just have to learn (anybody know?).

With Dmd you can use dmc directly. Second way is: you can compile your code as dll library and then create import library with implib utility for win32, for win64 a import library can be used directly. First way works good, but I prefer second one. Both approaches for win32 and win64 works good enough and stable.

Also C runtime can be statically compiled with your c/dll library. You just need copy c dll and your d exe without additional dependencies. C dll can be prepared by visual c.
