Hi there
I'm trying to use the SWI_Prolog V5.2.13 foreign language interface with
Borland C++ Builder V5.0 and I'm having a few problems.
When I try to embed prolog into a c++ application I get the error:
[C++ Error] testProlog.cpp(30): E2268 Call to undefined function
'PL_inifialise'
I have used implib successfuly and libpl.lib has been added to the project,
I have set the environment path, both in Autoexec.bat and in the code. I
have set the calling conventions to standard in the project compiler options
(although I cannot find the multi thread switch). I've included SWI-cpp.h
and SWI-Prolog.h in that order.
I'm also trying to create a Prolog extension dll, also in Borland Builder
and having problems with that too. I've created a dll project and libpl.lib
has been imported into this project, calling convention set to standard and
I've included SWI-Prolog.h and SWI-Stream.h (with SWI-Stream.h included
first as stated in the documentation). This time the errors appear in
SWI-Prolog.h, these are the error messages I get. I'm using the Hello World
example from the docs.
[C++ Error] SWI-Prolog.h(533): E2138 Conflicting type modifiers
[C++ Error] ExtTst.cpp(8): E2303 Type name expected
[C++ Error] ExtTst.cpp(8): E2451 Undefined symbol 'hello'
[C++ Error] ExtTst.cpp(8): E2293 ) expected
[C++ Error] ExtTst.cpp(19): E2141 Declaration syntax error
Help with this would be greatly appreciated.
Thanks
Mark Bennett
