Hi Viktor
Sorry but I know nothing about pcode .dlls, hence
there is no support for it in hbmk2 (yet?). I can't
recall anyone doing any tests with this (besides me
a while back, but without any results)
If you need a tester to this I would be glad to help. I'm working with
windows + hbmk2 + mingw.
To do anything in this regard, first I should see
how pcode .dlls are supposed to work, linked, etc.
I also need to see if this is something Windows
specific or portable. The latter would certainly
make it more interesting to deal with.
I don't know if this is what you are talking about, but I could tell as a
high-level user what is the expected usage and behaviour if that be the
case. I just used pcode dlls in windows enviroment, so I don't know much
about their portability also, but I believe there shouldn't be any plataform
dependant issues below to hb_libload function in this case. I don't think
they can be a "build once run everywhere" solution, but they sure can be a
"code once run everywhere" solution.
In the meantime I'd suggest to consider to use
.hrb files instead. Unless there is the need to
include .c code in these pcode .dlls, they are
superior in all aspects, moreover they already work.
Yes, that can be very good, but I don't know anything about .hrb modules.
Are they compiled or interpreted in run-time? What is the usage? Is there
any limitations on .hrb modules (variable and function scope limitations,
class declaration limitations, mt limitations) compared to statically linked
prg modules beyond support to c code? Are there any examples or
documentation on repository ?
Thank you for answering.
Best regards
Leandro

Hello
I have an aplication based on pCode Dll funcionallity. It was written in
xHarbour + BCC55 and now I need to know how to build it hbmk2+MINGW. In
xHarbour we could choose between 3 dll entry-points by chosing between
maindll.obj, maindllh.obj or maindllp.obj and once linking the dll with
maindllp.obj one just had to libload the DLL to make all its symbols be
brought to the "host" vm, just like using clipper+blinker DLLs. I see
that hbmk2 have and option -hbdyn to build dlls, but how do I tell hbmk2
that I need a pCode DLL and not a self-contained or harbour dll?
Ahd how about the load procedings? Should it work the same way as in
xHarbour (just libload the DLL and its functions will be available) or is
there any other formality to fulfill?
We had to threatfully make a few changes on the xHarbour vm to make
libload() work properly but they were so few and small that I believe
they can have been already solved in Harbour once its vm seems to have a
stronger design.

Leandro Damasio
