Hi,
I have some strange behavior on win XP with VC 8.0 version and
boost::random library.
When I use variate_generator helper template with uniform_01 distribution,
I always get an compiler error. like as:
//code
boost::mt19937 rng(time(0));
boost::uniform_01<mt19937> u01(rng);
boost::variate_generator die401(rng,
u01);
//compile info
error C2039: 'input_type' : is not a member of
'boost::uniform_01<UniformRandomNumberGenerator>'
with
[
UniformRandomNumberGenerator=boost::mt19937
]
f:\my documents\visual studio
2005\projects\testboost\testrandom\testrandom.cpp(169) : see reference to
class template instantiation 'boost::variate_generator'
being compiled
with
[
Engine=boost::mt19937,
Distribution=boost::uniform_01boost::mt19937
]
Actually, the uniform_01 class doesn't declare a type named input_type in
uniform_01.hpp, because uniform_01 distribution can accept both
IntegerType and RealType UniformRandomGenerator. It seems that
variate_generator can not support the uniform_01.
However, I found the engine_helper struct be specialized for uniform_01 and
uniform_int_float in variate_generator.hpp. I got confused. It's
vc8.0compiler's bug?
How can I get a variate_generator for uniform_01 distribution?
Any feedback welcomed!!
Thanks.
