Hi
I've tried to use the random.hpp header using Visual Studio C++ 6.0, and it
does not
compile. I found a message thread in the mailing list about this on VC7,
where some work-arounds were suggested. Jens then asked for feedback, and I
didn't find any feedback, so here it is...
For example, in uniform_01.hpp there is
template<class UniformRandomNumberGenerator, class RealType = double>
class uniform_01
{
//////// cut
public:
#ifndef BOOST_NO_LIMITS_COMPILE_TIME_CONSTANTS
BOOST_STATIC_ASSERT(!std::numeric_limits<RealType>::is_integer);
#endif
/////// cut
And VC6 breaks on the BOOST_STATIC_ASSERT when instantiating a
uniform_01<mt19937>.
The following suggested work-around DOES compile.
BOOST_STATIC_CONSTANT(bool, TMPx =
!std::numeric_limits<RealType>::is_integer);
BOOST_STATIC_ASSERT(TMPx);
The following variation does NOT compile.
BOOST_STATIC_CONSTANT(bool, TMPx =
std::numeric_limits<RealType>::is_integer);
BOOST_STATIC_ASSERT(!TMPx);
The following suggested work-around does NOT compile.
typedef std::numeric_limits<RealType> TMPlimit_t;
BOOST_STATIC_ASSERT(!TMPlimit_t::is_integer);
So far, so good you say. Just implement the first work-around.
However, I tried to instantiate uniform_01<mt19937, int> with this
work-around enabled. And guess what? VC6 does compile this STATIC_ASSERT as
well!
Just to test, I tried to use
BOOST_STATIC_ASSERT(std::numeric_limits<RealType>::is_integer);
This actually gives an error C2059: syntax error : '>', in both cases where
RealType is an int or a double...
So, as far as I can see, there is no point in having these static_asserts
enabled on VC6, and I am defining BOOST_NO_LIMITS_COMPILE_TIME_CONSTANTS
before including random.hpp.
All the best
