Solaris 11 and "error: no tap header could be found"

[noloader]

I'm working on an i86 based Solaris 11.3 machine. Running configure results in:

configure:15687: error: no tap header could be found

Inspecting config.log, it appears a Windows test or Linux test is triggering the failure (see below).

If I am parsing things properly, like bug reports and patches, Solaris patches were added several years ago around the 2.2 days. Confer, ​http://www.whiteboard.ne.jp/~admin2/tuntap/.

If Solaris is not supported, then please forgive my ignorance.

configure:15687: error: no tap header could be found

[Gert Döring]

If I remember right, you have to install the tun driver on Solaris first... as per the URL you found, ​http://www.whiteboard.ne.jp/~admin2/tuntap/, right at the top, section "TAP driver" .-)

The OpenVPN side of things has been merged, so if there is a tap driver installed, OpenVPN should find and use it without further patching needed. We do not have access to a most recent Solaris version, but from what I hear on the openvpn-devel, it should work nevertheless (we test on a older OpenSolaris? version).

[Gert Döring]

This is still somewhat of an itch. I tried OpenIndiana? 2019 recently, and while it has a package for the tap driver, that package is missing the header file - which can be copied from the package above. But really should be included.
