[SOLVED] C++11 string Error

[philippb]

Hi Guys,

I have a problem with running Kratos. The error message is the following:

Code: [Select]

|  /           |             
 ' /   __| _` | __|  _ \   __|
 . \  |   (   | |   (   |\__ \
_|\_\_|  \__,_|\__|\___/ ____/
           Multi-Physics 3.3.0
Traceback (most recent call last):
  File "test.py", line 3, in <module>
    model_part = ModelPart("a")
Boost.Python.ArgumentError: Python argument types in
    ModelPart.__init__(ModelPart, str)
did not match C++ signature:
    __init__(_object*)
    __init__(_object*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)
    __init__(_object*)

The input file is just a dummy input file.
It looks to me like the error is c++11 related.
The compilation of Kratos and all of the modules worked without any problems.

Thanks for your help and best regards,
Philipp

Hi,

Recently we moved to C++11, not officially, but we are moving there step by step. Did you included the comment in configure.sh for the C++11?:

Code: [Select]

-DCMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -msse3 -std=c++11"         \
Remember that Boost should be compiled with C++11 too.

Additional questions:

• Which version of gcc are you using?
• Which version of Boost are you using? Rememeber that we are just supporting until Boost 1.59

Hi,
Thanks for your reply!
I recompiled Boost (Version 1.55) and Kratos with C++11 enabled, but unfortunately I still get the same error.
GCC is version 5.3.0

Do you have another idea?

Best regards,
Philipp

Try with Boost 1.59 and tell me.

mmm

version 1.55 is already pretty recent i don't think that the error comes from that.

be sure to remove the whole /libs directory when you compile/install

Recompiling boost (1.55) with C++11 and recompiling kratos (with deleted /libs directory) did the trick.
Thanks for your help!
