I've got one header foo.h and two source files main.go and bar.go.

foo.hcontains two functions: foo(), bar()

In main.go I am calling C.foo(), in bar.go I am calling C.bar().

Both import pseudo-package "C" and #include "foo.h"

Although I added include guards to foo.h, I am getting the following error:

In function foo: /path/too/foo.h: multiple definitions of foo

Likewise for function bar()

How are you building your package? – JimB Jul 02 '18 at 12:56
`go build github.com/path/to/pkg/main` and all of those files are in `package main` edit: editing path to package main – daniel-scholz Jul 02 '18 at 13:07
i actually did that, i just commented incorrectly. – daniel-scholz Jul 02 '18 at 14:05
the error says you have "multiple definitions" when including `foo.h`, but a header should only have declarations. Check the contents of the header file. – JimB Jul 02 '18 at 14:10
the ```foo.h``` contains multiple headers, in particular some ```winnt.h``` and ```intrin-impl.h```, which are not defined by me – daniel-scholz Jul 03 '18 at 05:30
