Hi,

Sorry guys, but it seems to me you both mix Harbour.dll
with general purpose dll libraries used by a system.

So, what difference do you see between Harbour.dll and "general puporse dll". Why Harbour.dll could not be a general puporse dll? What are requirements for dll to be a general puporse?


It's not the case. The problem is C standard Runtime
library. Each C compiler has its own dynamic CRTL designed
and compiled for that compiler. Harbour uses C Runtime
library extensivly. If I would like to create and use
Harbour dll which uses *dynamic C Runtime library" I will
not be able to do so - following your aproach.
And in fact I do this. My HbWxW uses Harbour dll AND
dynamic CRTL (Borland build).

Not sure I've got your idea well... I'll try to ask a two questions:

1) Can we link static C RTL to harbour.dll? I mean all C RTL functions like memcpy(), etc. will be inside inside harbour.dll, but not Borland's cc3250.dll. This way our harbour.dll will be "self contained" it will not depend on external borland's code.

2) If 1) is true, do we have any other problems to use BCC compiled harbour.dll with another C compiler?

OK, I see some problems here. Some functions depends on structures created by RTL, for example I guess we'll have GPF if we allocate memory using Borland's malloc() (from harbour.dll) and free it using Microsoft's free() (from main app). This should be solved by forcing main app to use .dll hb_xgrab(), hb_xfree().


Or do you want to have a "final word" again ?

No need for final word. Final solution would be better.

Perhaps more problems could by found, but I really think there is a solution for the problem. I used various .dll, for example: zlib.dll, libcairo.dll, libmysql.dll, ace32.dll, gtk, MrSID, etc, etc. I did not care that compiler it was compiled. I've used it from both GCC and Borland. Original binary distribution very ofter come with COFF import library (perhaps MSVC), but I've used Borland's implib.exe, and used created import library with success.


Best regards,
Mindaugas
