Building OpenVPN for Windows from Git using openvpn-build/generic fails

[Samuli Seppänen]

Building latest OpenVPN Git sources fails miserably:

socket.c: In function ‘socket_bind’:
socket.c:1120:7: warning: passing argument 4 of ‘setsockopt’ from
incompatible pointer type [enabled by default]
       if (setsockopt(sd, IPPROTO_IPV6, IPV6_V6ONLY, &v6only,

This is reproduceable on Ubuntu 14.04 64-bit configured using using the automated setup script .

On Ubuntu 12.04 that has an older mingw_w64 version there are additional issues, of which some (but not all) are fixed in the ​ patched versions of NSIS packages .

I reproduced this by creating openvpn-2.3_git.tar.gz using make dist-gzip and putting that to a webserver. Then I simply overrode the build parameters:

OPENVPN_URL="http://build.openvpn.net/downloads/temp/thomas/openvpn-2.3_git.tar.gz"\
INSTALLER_VERSION="903"\
OPENVPN_VERSION="2.3_git"\
./build-complete

The build-snapshot script should produce the same results (provided it works).

I'll take it. We'll benefit a lot from being able to build master snapshots for windows again :-)

[Gert Döring]

Now that was quite easily fixed, by letting d12fk and plaisthos do all the work :-)

Let's hope we'll see snapshot builds on the download area soon!

The "automatically publish Windows snapshot builds" is next on my todo, so we don't have to wait too long.
