Hi, I recently ran into an issue related to two compilers giving different values for __GXX_ABI_VERSION [1]. The two compilers were gcc 5.1, which reported '1008', and clang 3.6, which reported '1002'. The issue is that a library (wxWidgets) produces a fatal runtime error if there is a mismatch between the __GXX_ABI_VERSION of the compiler used to build the library, and the compiler used to build the application using the library. What I'd like to know is: - what exactly does __GXX_ABI_VERSION signify? - why do gcc 5.1 and clang 3.6 report different values? - is the library's behaviour (of producing a fatal runtime error upon a mismatch) appropriate? Thanks, Nate [1] http://thread.gmane.org/gmane.comp.lib.wxwidgets.general/83315
