When
using -buildmode=c-archive or c-shared, and
when installing packages that use cgo, and
when those packages export some functions via //export comments,
then
for each such package, install a pkg.h header file that declares the
functions.
This permits C code to #include the header when calling the Go
functions.
This is a little awkward to use when there are multiple packages that
export functions, as you have to "go install" your c-archive/c-shared
object and then pull it out of the package directory. When compiling
your C code you have to -I pkg/$GOOS_$GOARCH. I haven't thought of
any more convenient approach. It's simpler when only the main package
has exported functions.
When using c-shared you currently have to use a _shared suffix in the
-I option; it would be nice to fix that somehow.
