topology can't be allocated in Go (Is this being maintained)?

[vsoch]

I just tried adding to my library, and:

mkdir -p /home/vanessa/Desktop/Code/compspec/compspec-go/bin
GO111MODULE="on" CGO_CFLAGS="-I/home/vanessa/Desktop/Code/compspec/compspec-go/lib/include" CGO_LDFLAGS="-L/home/vanessa/Desktop/Code/compspec/compspec-go/lib/lib -lhwloc" go build -ldflags '-w' -o /home/vanessa/Desktop/Code/compspec/compspec-go/bin/compspec cmd/compspec/compspec.go
# github.com/c0mm4nd/go-hwloc
vendor/github.com/c0mm4nd/go-hwloc/topology.go:22:36: _Ctype_struct_hwloc_topology can't be allocated in Go; it is incomplete (or unallocatable)
make: *** [Makefile:28: build] Error 1

From this https://forum.golangbridge.org/t/type-is-incomplete-or-unallocatable/33565 I think likely a pointer is needed somewhere? Also let me know if you are still maintaining this. Thank you!

Currently having this issue as well, going to investigate. I remember building this library a few months ago with no issue, so most likely this has to do with an updated library.

If I manage to get it working I'll create a fork and link it back here

Update: Forked the project with the struct allocation fix.

@0xffffa are you planning to contribute via PR here so we can use the upstream for our projects? Or are the changes not acceptable for adding here?

@0xffffa @c0mm4nd @vsoch @carmark In version 1.13 of Golang, it can be built perfectly. However, the latest version of Golang may encounter errors (go hwloc \ topology_windows.go: 335:59: cannot convert pid (variable of type HwlocPid) to type_Ctype_cwloc_pid_t), if unsafe is used The Pointer function will result in an error when converting (go hwloc/topology_windows.go: 20:36: _Ctype_struct_hwloc_topology can't be allocated in Go; it is incomplete (or unallocated)). Do you have any good methods?
