I'm trying to use wkhtmltopdf[1] with D. I converted this
header[2] with little modification using htod tool which
resulted in this[3].
The libray is passed to link using:
pragma(lib, "wkhtmltox.lib");
(that file is in wkhtmltopdf\lib folder)
and the module imported with:
import pdf;
but it crashes right upon the start with a SEGFAULT:
void main()
{
wkhtmltopdf_global_settings * gs;
wkhtmltopdf_object_settings * os;
wkhtmltopdf_converter * c;
/* Init wkhtmltopdf in graphics less mode */
wkhtmltopdf_init(0);
}
toolset I'm using:
DUB version 1.8.1, built on Apr 29 2018
LDC - the LLVM D compiler (1.9.0):
based on DMD v2.079.1 and LLVM 5.0.1
built with LDC - the LLVM D compiler (1.9.0)
Default target: i686-pc-windows-msvc
Host CPU: skylake

What's likely the reason of the crash? mismatch between D and C
memory alignment?

You're missing const on a couple of the pointer parameters, but
if it segfaults on calling a function then my question is: is
wkhtmltox.lib a library that was generated to link to a dynamic
library (is there an associated .dll)? If so you need to ensure
that it is loaded and the function pointers are initialised.
