Compiling QuantLib v1.9 results in error: class ‘QuantLib::GaussianWalk’ does not have any field named ‘DistributionRandomWalk’

Here's the compiler output:

Yes, it looks like there's a missing template parameter in the name of the base class in the initialization list. Strange, though. The release was tested with at least 3 or 4 different versions of g++ and clang and none complained. Which one are you using?

[aloupos]

Thanks so much for looking into it!

Ok, the oldest version I checked was gcc 4.8. The commit above should have fixed this on the 1.9.x branch. Can you check it out or download it from the green button on https://github.com/lballabio/QuantLib/tree/v1.9.x and test it? (You'll also need to run ./autogen.sh before ./configure)

[aloupos]

Indeed it does! Thanks very much for the speedy fix.

[lballabio]

No problem, thanks for the heads-up.
