Problem with C.RTLD_NODELETE and C.RTLD_NOLOAD

[ManPython]

When trying run in VSC button.go then

..\..\..\..\..\bin\pkg\mod\github.com\kitech\[email protected]\dl.go:21:19: could not determine kind of name for C.RTLD_NODELETE
..\..\..\..\..\bin\pkg\mod\github.com\kitech\[email protected]\dl.go:20:19: could not determine kind of name for C.RTLD_NOLOAD
exit status 2
Process exiting with code: 1

Is this can be related with https://github.com/kitech/qt.go/issues/43 ?

In short, No.

The latest code already comment this two symbols: https://github.com/kitech/dl/blob/fa7e1b9bab3dc216669acf2215c8a88cb3675ddc/dl.go#L21

So just update kitech/dl is fine, go get -u github.com/kitech/dl

So how you get a old version package? seems go module do that?

The VSC automaticly downloaded all when "Lanch GO". In fact it is commented as in link in Go\src\github.com\kitech\dl . But not commented on Go\bin\pkg\mod\github.com\kitech\[email protected] Not sure why old version was downloaded.

I made experiment by replace new source code to this old version, but is no sense probably as bellow;

# github.com/kitech/qt.go/qtrt
..\qtrt\ffi_invoke.go:10:17: fatal error: ffi.h: No such file or directory
compilation terminated.
exit status 2
Process exiting with code: 1

Now the log from VSC is similar like https://github.com/kitech/qt.go/issues/43#issuecomment-522253177

Try disable go module support. Not test too much.

I create a PR updating the dl pinning in the go.mod (#52). I belive this solves the problem, as the current pinning points to an old version that requires this symbols from dlfcn.h.
