c++11 support

Hello, everyone!

I succeeded to build the OpenCascade v7.3.0 using various compilers (VS2010-VS2017, GCC4.8, GCC4.4) in various modes and everything finished great. However, when I tried to build my application (which previously used v6.9) with the v7.3.0 one, everything worked great on newer MS compilers, but, I hit errors with GCCs, which say I need to build with c++11 support enabled.

Does the latest OpenCascade sources require partial c++11 support or I'm using wrong the framework?

Best regards,

Hi, Nenad,you can find the

Hi, Nenad,

you can find the necessary information in the documentation (https://dev.opencascade.org/doc/overview/html/occt_dev_guides__upgrade.html)

Upgrade to OCCT 7.0.0
Porting of user applications from an earlier OCCT version to version 7.0.0 requires taking into account the following major changes.

Building OCCT now requires compiler supporting some C++11 features. The supported compilers are:

MSVC: version 10 (Visual Studio 2010) or later
GCC: version 4.3 or later
CLang: version 3.6 or later
ICC: version XE 2013 SP 1 or later
When compiling code that uses OCCT with GCC and CLang compilers, it is necessary to use compiler option -std=c++0x (or its siblings) to enable C++11 features.
