Unresolved XML entities

[fcharp]

I've had this problem for a few days now. In order to try and avoid bugging you, I rebuilt NETMapnik with the following config:

• VS 2015 (14.024) Professional
• .NET 4.5.2
• x64
• Mapnik 3.100
• Boost 1.100

Building NetMapnik put up a fight, but it's all good now, and the various c# tests included in the snapshot are working. What's not working: when using Map.Load("foo.xml"), XML references are unresolved and throw an exception. Just to be clear: I tested the XML file with mapnik.dll and it worked fine. To make absolutely sure that it was not an external file issue, I tested this:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Map [
  <!ENTITY srs900913 "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs +over">]>
<Map srs="&srs900913;">
</Map>

Map.Load comes back with "failed to initialize projection with: '&srs900913;' ". If I replace the reference in "srs=" with the definition, it works. That seems to suggest that the parser is working, but not able to resolve references. Of course, I always live with the nagging doubt that I am missing something that's staring right at me :-). I thought that you may have an idea. Short of that, I am faced with rebuilding libxml2 in order to step through the code, which is not something I am really crazy about at this time.

P.S.: if I can get this resolved, I will be happy to send you the build for VS2015. Other than type conversion warnings, it seems to do the job.

Interesting, since entities are only supported if mapnik is built with libxml2.

Thank you so much for the reply. I feel bad for not digging deep enough in the blogs. Re: mapnik.dll. You are right: I was using the examples from mapnik-fork, which included a different dll. My bad again. I will go on with the pointers you gave me. Thanks for looking so diligently after the project.
