Hi,

using
http://misspent.wordpress.com/2009/09/27/how-to-write-boost-python-converters/, I 
tried to write a converter for list to std::vector<T>  (In the example, T will 
be double).

The code (see converter.cxx) I wrote is still in early stage of
development (no check) but compiles fine on ubuntu oneiric with boost
python 1.46. I used it to create an std module. However, a simple test
(see test.py) does not work as exepted.

Did I misunderstood something or does boost have a special treatment for
the list object which bypasses converters ?


The problem is that your "print" function takes a std::vector by reference, and you've defined an rvalue converter, which will only match value or const reference arguments. In other words,

void print(std::vector<double> const & v) {...}

or

void print(std::vector<double> v) {...}

should work.  Everything else looks good.

HTH!
