#11315 assigned Bugs

Compilation warnings created by boost::polygon::operators

Reported by: lopresti@… Owned by: Andrii Sydorchuk
Milestone: To Be Determined Component: polygon
Version: Boost 1.58.0 Severity: Problem
Keywords: Cc:


When I compile (attached) with Clang and enable "-Wall -Werror", the compilation fails with "template argument uses unnamed type". See attached "warnings.txt" for complete output.

This took me a little while to track down, since the error occurs on a call to "*" using primitive types (!).

I am not sure this is really a bug in boost::polygon, and I am not sure how to fix it if it is, but I thought I would report it anyway.

I found this report looking for a similar problem with compiling KiCad? which uses the boost::polygon library. The issue / solution is that using unnamed types in a template argument was illegal using older C++ standard. Using C++0x, it is allowed. So.. you can compile this without warning / error by adding -std=C++0x to the clang++ call.
