Failure to generate with castxml for c++11 type within orogen

[vbargsten]

In a ROCK installation, I am using a c++11 type within a struct and get an error such as

In file included from /usr/lib/gcc/x86_64-linux-gnu/6.3.0/../../../../include/c++/6.3.0/tuple:35:
    /usr/lib/gcc/x86_64-linux-gnu/6.3.0/../../../../include/c++/6.3.0/bits/c++0x_warning.h:32:2: error: This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
    #error This file requires compiler and library support \
     ^
    1 error generated.

when building an orogen component using this type. I found that it works when calling castxml with "-std=c++11". I tried to set TYPELIB_CASTXML_DEFAULT_OPTIONS using export and using Autobuild's package.define method, but the option is not respected. Hard-coding the option into typelibs ruby bindings for calling castxml works.

Hi @vbargsten. So far, orogen itself has unfortunately no way to specify the C++ standard it should be using on the command line and/or through the orogen file. This would be a welcome addition (hint hint ... ;-))

It will automatically "switch" to C++11 if one of the used libraries (through using_library) uses it and specifies the standard in its pkg-config file.
