I have a piece of cgo code which doesn't do much, but links a lot of
libraries in. As far as I can tell all my includes are there and they
shouldn't stomp on each other (they don't when compiled in C), however
with cgo I get the following weirdness:
$ go build
# mypkg
Undefined symbols for architecture x86_64:
"___DARWIN_NULL", referenced from:
__cgohack___DARWIN_NULL in _cgo_main.o
(maybe you meant: __cgohack___DARWIN_NULL)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
If I decide to be bold and #define __DARWIN_NULL in my Cgo preamble
(before "import C"), I get the following:
$ go build
# mypkg
./main.go:53:9: warning: '__DARWIN_NULL' macro redefined [-Wmacro-redefined]
/usr/include/sys/_types.h:52:9: note: previous definition is here
I'm a little bit stumped. How to debug the chain on #includes to get
to the bottom of this? Why is this not a problem elsewhere?
