On Solaris, activating C++11 standard switch the compiler into a completely different mode: * Mangling is different * C++ runtime is the GNU one, delivered as part of SolarisStudio 12.4 (Sun C++ runtime is no longer supported)
This is why the flag -std=c++11 must be passed to the link step to enable compiler to select the correct runtimeā¦ Marc On 28/09/15 21:20, "cmake-developers on behalf of Brad King" <cmake-developers-boun...@cmake.org on behalf of brad.k...@kitware.com> wrote: >On 09/28/2015 02:34 PM, Stephen Kelly wrote: >>> Steve?
