what I meant was that p9p is used on unix-like systems.
with that in mind, what if i wanted to:
% cat a.cc
#include <iostream>
#undef _XOPEN_SOURCE
#define NOPLAN9DEFINES
#include <u.h>
#include <libc.h>
#include <draw.h>
#include <geometry.h>
int
main(void)
{
Point3 x = {1,0,1}, y = {0,1,1}, z;
z = add3(x,y);
std::cout << z.x << std::endl;
std::cout << z.y << std::endl;
std::cout << z.z << std::endl;
return 0;
}
% g++ -I$PLAN9/include -c a.cc && g++ -o a a.o $PLAN9/lib/libgeometry.a
% a
1
1
2
without the extern definitions?
sorry if i was harsh.
