>From your question COM or header, I assumed you are only interested in windows. I also assume that you don't want to export functions defiend. So, I did the following: - removed PDFLIB_API and PDFLIB_CALL (point 1 in my previous message) - replaced the L".." defines by one to the char version (point 2)
The result from h2pas is attached. What needs to be done:
- add stdcall; behind all functions that had PDFLIB_API. Both in interface
and implementation part.
- if you are linking dynamically replace in the functions that had
PDFLIB_CALL in the implementation part
begin
{ You must implement this function }
end;
with
external 'name of the lib';
- as always, review the translation

In this case:
1) because h2pas doesn't use pascal macro's. A construct like #if
defined(WIN32) && !defined(PDFLIB_CALL)
#define PDFLIB_CALL __cdecl
#endif
can not be translated using pascal constants or functions. Cdecl is a
calling convention modifier.
2) afaik pascal doesnt support widestring constants. Therefor h2pas doesn't
understand
#define IFILTER_WCHAR_LONG_VERSIONSTRING L"4.0p7". In this case, the
string doesn't contain non-ascii characters and pascal will assign (convert)
correctly a ascii string to a widechar string. So you can just solve the
problem by
const IFILTER_WCHAR_LONG_VERSIONSTRING=IFILTER_LONG_VERSIONSTRING;

Anyone?
At least tell me why h2pas can not parse this header file, please.
