I'm using MinGW for the compiler. Here's the header file, point.h: //type for a Cartesian point typedef struct { double x; double y; } Point; Point create(double x, double y); Point midpoint(Point p, Point q); And here's point.c: //This is the implementation of the point type #include "point.h" int main() { return 0; } linker error undefined reference to __chkstk_ms' Point create(double x, double y) { Point p; p.x = x; p.y = y; return p; } Point midpoint(Point p, Point q) { Point mid; mid.x = (p.x + q.x) / 2; mid.y = (p.y + q.y) / 2; return mid; } And here's where the compiler issue comes in. I keep getting: testpoint.c: undefined reference to 'create(double x, double y)' While it is defined in point.c. This is a separate file called testpoint.c: #include "point.h" #include
