What I am doing wrong?
I think there is something the D language does before starting main.
And the C language does not. Can I initialize the program correctly
manually? Or it is another problem altogether?
The D runtime does quite a lot before running D main. You would need to
a least initialize the runtime. Here's the C main function that is run
before D main:
https://github.com/D-Programming-Language/druntime/blob/master/src/rt/dmain2.d#L384
Here's the function to you can call to initialize the runtime from C:
https://github.com/D-Programming-Language/druntime/blob/master/src/rt/dmain2.d#L281
And to terminate:
https://github.com/D-Programming-Language/druntime/blob/master/src/rt/dmain2.d#L312
I'm not sure if all this work yet. Using a D shared library from a D
application, "statically" linked, should work on Linux 64bit. Don't know
if it works from a C application.
