Not Matching C++ signature

[Alessandro Candini]

I'm using Mapnik 2.1 and I would like to generate my own slippy map with
generate_tiles.

But when I launch render_tiles function I get the following:

File
"/home/meeo/CanetaRepo/tmp/lta_arch/lta_proj/lta/generate_tiles.py",
line 136, in render_tiles
renderer = RenderThread(tile_dir, mapfile, queue, printLock, maxZoom)
File
"/home/meeo/CanetaRepo/tmp/lta_arch/lta_proj/lta/generate_tiles.py",
line 64, in __init__
mapnik.load_map(self.m, mapfile, True)
ArgumentError: Python argument types in
mapnik._mapnik.load_map(Map, unicode, bool)
did not match C++ signature:
load_map(mapnik::Map {lvalue}, std::string)
load_map(mapnik::Map {lvalue}, std::string, bool)

What does this mean?

Thanks in advance

You need to convert unicode into ascii string for the second argument :

```python
load_map(<your-map-object>, str(<path-to-map.xml>))
```
