[gecode-users] FloatVar with Gecode 3.7.1

[Sam Yoffe]

Hi Christian,

Many thanks for the quick response. Yeah, too bad! If Vincent has any suggestions, I would be happy to hear them and try to get something going. Otherwise, am I best using something like quotients for now until 4.* hits the (metaphorical) shelves?

Best,
Sam

I realise this is a fairly old question so I'm sorry if this has recently been answered elsewhere, but I can't seem to find any answers which are not several years old. I would like to use floating point variables with gecode. I found floatvars over on google code, but their install instructions seemed to be for gecode 2.2 whereas I would like to continue using 3.7.1 if possible. I couldn't seem to get the same installation method to work, even when building from source with the --enable-float-vars flag. I also found Gecode::FlatZinc::AST::FloatVar and managed to get it to compile, but I couldn't do much with it. Also, it seems to require an integer in its constructor, is this just an identifier? I found several references in old threads to the Boost libraries, which I don't currently have installed. Is this required?
