Hi Ari,<br>
<br>
I haven't tried to compile that with mono for quite a long time. I'll give<br>
it a try.<br>
<br>
However we did not follow the latest changes in the SWIG implementation<br>
with the bindings, so I'd try with an earlier version (ie. 1.3.39) to<br>
generate the wrappers.<br>
</blockquote>
I can confirm that I can compile the CSharp bindings on Linux with SWIG 1.3.40<br>
(and run the tests), but I get the same error as Ari with SWIG 2.0.X<br>
<br>
As far as I know, Java and Python bindings build and run equaly well with SWIG<br>
1.3.40 or 2.0.X (although there's a Unix makefile hack to have Python 3.2<br>
compat, conditionnaly applied with SWIG 1.3.40, that is no longer needed with<br>
SWIG 2.0.4 or later)<br>

Swig 1.3.39 seems questionable. Just look at the download amounts at sourceforge. 1.3.39 one download and 1.3.40 148 downloads per week.<br>
<br>
However, 1.3.39 does *not* put the PVINVOKE() method twice into the PVINVOKE.cs file.<span class=""><br>

May be we should consider including the generated<br>
wrappers in gdal instead of let the users to use different versions with<br>
different results.<br>

It would be good if we could have a common SWIG version that works for all the<br>
bindings. So currently it seems to be 1.3.40 ?<br>
<br>
Regarding putting the generated wrappers in SVN, that's already what we do for<br>
Python. We could also just include the generated wrappers in the tarballs.<br>

IMO "users" = people who use ready-made packages. Developers and packagers should be intelligent enough to use development tools. I don't like the idea of having generated files in source repositories. I'm also of the opinion that there should be a really good reason to use an old version of a common tool. And at least in my Linux (Mint, Maya - hmm, that seems already pretty old, I should upgrade) swig 2.0.11 is the current. But that's just me I guess.<br>
