I'm taking a crack at that right now. Seems doable.<br>
What C++ doesn't like at all is the implict cast from void* to <br>
something_else*, that need to be explicited in C++ as static_cast<>()<br>
<br>
Beyond those errors, a lot warnings which seem to be exclusively instances of<br>
-Wzero-as-null-pointer-constant. clang-tidy should be able to convert those.<br>

<br>
I think that an "invalid" operation would be a better fit for those. We don't <br>
want such objects to be confused with valid coordinate transformation<br>
"noop" is a valid operation when there is nothing to do except passthrough <br>
coordinates. If the PJ object you got is let's say a prime meridian, it is <br>
better if proj_trans() returns an error rather than the input values.<br>
(but that's just a detail)<br>
