doesn't anybody know?

I think I've pulled off the first stumper of all the newsgroups :( As
far as I can tell, there seems to be no way to compile a .OBJ file in BC++
3.1 so that Turbo Pascal 7.0 can use it. There must be a way, right?

does TP7 reject an .OBJ file that is just barebones c++ code (the minimal
needed to make a running program)?

Are you trying to write C or C++?

What library functions are you calling?

Are you linking in TP7 with the C-libraries too?

Well, If I recall correctly, you can't use any global variables in the .obj
file. Use extern in the 'c' code to reference the variables created in the
Pascal Program.
I don't know why, but this worked for me.

I have personally done this, so if you give me a tiny example file of the
'C' and 'Pas' and email it, I will show you how in a few days. (After I
do it)

like

unit hello;

procedure somefunction:byte;

{$L something.obj}

imp;

begin
somfunction;
end;

All I did was write a simple function in c:

int square ( int x )
{
return x * x;
}

had a header file which just contained a forward declaration of the
function, a cpp file which had the function itself, compiled it into a .OBJ
file, tried to include into TP7.0 with {$L square.obj} and it said:

"invalid object file" (maybe: "invalid object file record")

Any ideas?

Try:

extern "C" {

int square ( int x ){

return (x*x);
}
}

Hope this helps,

You probably need to define your function as a C function, otherwise CPP
will mangle the name.
