I tried to create an example that more closely resembles what
is in LearningD (see
https://github.com/aldacron/LearningD/tree/master/Chapter09_Connecting%20D%20with%20C/clib). I created two files
clib.c
----------------
#include <stdio.h>
int some_c_function(int);
int some_c_function(int a) {
printf("Hello, D! from C! %d\n", a);
return a + 20;
}
and
dclib.d
-----------------
pragma(lib, `libclib.lib`);
extern(C) @nogc nothrow {
int some_c_function(int);
}
void main()
{
import std.stdio : writeln;
writeln(some_c_function(10));
}
------------------
I then ran
gcc -Wall -fPIC -c clib.c
gcc -shared -o libclib.dll clib.o
implib libclib.lib libclib.dll
That should be implib /system libclib.lib libclib.dll. I'm pretty
sure the /system option is required. (Also be sure you are not
mixing 32-bit or 64-bit libraries. I don't think implib works
with 64-bit.)
I'm getting an error on the implib command on my home computer.
Maybe running it on a different computer would work.
The LearningD book says that you should compile the libraries
with DMC on Windows, but I can't figure out how to generate a
shared library on DMC. I didn't get the implib error for what I
was working on before.
You won't need to use DMC if you're using implib.
I feel like getting stuff to work with Windows is always such a
hassle, but that's the only way I'll be able to use this stuff
at work.
It definitely is more difficult.
