Hi Frediano,

Sorry for such a belated reply. Life insists on keeping me away from
having fun with this. Thanks for making me realise I never posted to
the list.

Actually I tried the regsrv32 path but it fails for some reason I
can't understand (IIRC OS reported error level 3), that's why the
[1]relevant line is commented out. The lines below it (the ones that
execute dbconf.exe) aren't sucessful either, as I uderstand they also
try to register the driver with the ODBC manager. I copied all this
from old posts to this list.

Exactly, I managed to get iconv to get linked in by using the
win-iconv project but the [2]technique I used is too hacky and that's
why I haven't proposed it (hacky = too windows-specific and too
win-iconv-specific.)

Actually, I set up thing such that if openssl or iconv aren't
available the build doen'st fail and CMake proceeds to buld FreeTDS
with these features turned off. That's what's happening.

I have some work in progress to get iconv (GNU libiconv, win-iconv)
detected and linked in when using CMake by grabbing ideas and snippets
from multiple sources around the Net. Unfortunately a module that
performs such detection hasn't been added yet to CMake itself even
when people has been proposing it for something like the last seven
years.

If/when we add it to our CMakeLists.txt then it will find and link in
the win-iconv copy we already build on AppVeyor.

Ok, in fact 64 bit ODBC stuff can be completely borked because I
didn't care about ii at all, hoping to get the basic ODBC stuff
working at leats with one configuration first.

Thanks for your continued work on master. I see you are already
planning a second release this year. Wow.

While we are at the AppVeyor Window CI builds topic and now that the
needed files are alredy in the tree I'd like to suggest a remaining
step I described in a [3]comment to the Pull Request:

<quote>
Note: If/when this gets merged, an account needs to be created in
Appveyor by a GitHub FreeTDS organization member/owner (possibly using
GitHub credentials) and then project settings on Appveyor need to be
changed so it scans for the appveyor.yml file in the misc/ subdir
instead of the source tree root.

This would be the only Web UI action needed. Everything else can be
handled with the appveyor.yml file.
</quote>

Doing this would give us builds that are automatically triggered on
AppVeyor under the FreeTDS account from every new commit/PR (and
having the build results getting reported in the GitHub UI) without
having to rely on me manually rebasing my ramiro/appveyor branch on
master from time to time and getting these build/results under my
personal account/URL hierarchy.
