Hi,
i tried to link a c function but had some problems:
a simple example:
in file cwrite.c
#include <stdio.h>
void writestringinc(void);
void writestringinc(void) {
puts("This string is written using c");
fflush( stdout );
}
compiled with c using
g++ -c cwrite.c
now, this is a test program in fpc:
Program testc;
{$linklib c}
{$L cwrite.o}
Procedure writestringinc; cdecl; external;
begin
writeln ('Written with Pascal');
writestringinc();
end.
both cwrite.o and testc.pp reside in the same directory.
compiling with fpc gives me this:
[EMAIL PROTECTED] c++progs]$ fpc testc.pp
Free Pascal Compiler version 1.9.1 [2003/11/14] for i386
Copyright (c) 1993-2002 by Florian Klaempfl
Target OS: Linux for i386
Compiling testc.pp
Linking testc
testc.o(.text+0x4a): In function `main':
: undefined reference to `writestringinc'
testc.pp(11,1) Error: Error while linking
Closing script ppas.sh
What am I doing wrong?
Another question: is fpc compatible with C++?
Thanks in advance,
Ciao, Dean
