Also are you using bjam to build or are you using CMake? It also looks like you're using it in your own application. It would be great if you can post a minimal example that would help me better diagnose the problem. > And: > > In file included from >

I think 0.9-devel has been developed with the -Wall option, but this one looks like you're using the -pedantic option (is that correct?). I'll try building/running the tests with -Wall on 0.8.1 and see if I can reproduce. Also, do you mind filing issues on https://github.com/cpp-netlib/cpp-netlib/issues so that we can track the progress on this? Thanks for reporting Stephane! -- Dean Michael Berris about.me/deanberris |
