I got as far as

Hi Brendon, do you have openvpn headers installed?
If so, what's the headers location?

I got past the headers issue. I found another issue with something about it. Fix is:

pkg install openvpn-devel-201725
mkdir /usr/include/openvpn
cp /usr/local/include/openvpn-plugin.h /usr/include/openvpn

The new issue ...
I looked at some of the endian.h files but they are all different. I'm not sure which one I should even attempt to make work. Any ideas?

Here's how I got it to work, this was back on pfSense 2.1 or 2.2 I think.

  • Install FreeBSD compatible with pfSense version
  • Install ports
  • Install openvpn-devel via ports
    WITHOUT_CHECK=yes make install
  • Install autotools
  • Download & Extract & cd into openvpn-otp
  • Compile
./autogen.sh
./configure --prefix=/usr/local CPPFLAGS="-I/usr/include/machine/ -I/usr/local/include/"
make
  • Copy src/.libs/openvpn-otp.so to pfSense, e.g. /usr/local/lib/openvpn-otp.so

Guys, I don't have time to test it on FreeBSD. If anyone has it 100% working, I'd be more than happy to accept a pull request that will add a FreeBSD HOWTO section to readme.md

@RNCTX commented on GitHub (Jun 20, 2018):

Stumbled on this via google. Got warnings during compile using suggestions in this reply about machine/ being deprecated in favor of sys/ (on FreeBSD 11.1-RELEASE). There is a hard-coded search path for /usr/include somewhere, because prefixing /usr/local as FreeBSD uses does not find the openvpn headers. Unfortunately the FreeBSD openvpn package does not include any pkgconfig files, so pkgconfig wouldn't help.

So my modified configure was...

./configure --with-openvpn-plugin-dir=/usr/local/lib/openvpn/plugins --prefix=/usr/local CPPFLAGS="-I/usr/include/sys -I/usr/local/include/"

after making a symlink to the header where the autoconf tools in this distribution want it...

ln -s /usr/local/include/openvpn-plugin.h /usr/include/openvpn-plugin.h

This is assuming that openvpn was installed from ports or the official FreeBSD pkg. The plugin directory above is the FreeBSD port/pkg default.

I built it successfully, but haven't tested yet. Here are the warnings...

Hey Robert,

I've done zero testing on FreeBSD, and while I still like the OS, I have no
free time to test that. I am sure somebody else had some success in it.
You're welcome to provide a fix via a pull request.

Regards,
Evgeny.
