Hi Andreas,
I'm no expert in that field but somebody who is might take a look at http://gcc.gnu.org/wiki/Cxx11AbiCompatibility and http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53646
thank you for these insightful (and admittedly frightening) links. Given these discussions, mixing compilation units compiled with -std=c++11 and -std=c++98 looks risky indeed. It seems that the problem can be avoided only by compiling the whole C++ code base consistently with one kind of -std argument. But I wonder how do Linux distributions do that? For example, if Qt5 uses C++11, does it mean that Qt5 must not be linked to programs compiled with -std=c++98? This is hard to believe.
As far as I understand the above deal mainly with issues within the standard library which might not be a problem when relying on the genode toolchain but could for the lx_hybrid platform.
I agree. But how should we go about this?
Cheers Norman
