the new commit, capi.cc add the <string.h> header for memcpy: https://github.com/chai2010/guetzli-go/commit/015096ec963d81cd19a45d241e272e141872be96

please try again. thanks

Thanks, it works. But there's another warning:

[chai2010]

you can try add the ldflag to the cgo.go's cgo comment:

#cgo linux LDFLAGS: -Wno-subobject-linkage

ps: it is not work on the windows(gcc version 5.1.0 (tdm64-1)). i don't know the reason.

patch are welcom!
