 Hello,
 
 i'm trying to build the recent master branch of the crash utility and
 not able to build eppic extension. 
Hi Alex,
Thanks for the report, it's the same on my machine, I forgot this..
Seems that it doesn't support gdb-10.2 currently.
I've cc'd Luc, who is its maintainer.  Any information about this?
Thanks,
Kazu

 Exactly the same problem is occurring on s390 architecture.
 
 I find it's very weird that a C library like eppic is including a C++
 header from GDB.
 
 gdb-10.2/gdbsupport/common-defs.h is a C++ header containing includes of
 other C++ headers like cstdlib, array etc. Furthermore, it contains C++
 templates !
 
 Has anybody tested this ? Maybe i'm doing something wrong :/
 Would appreciate any hint how to fix this. So far i haven't figured out
 howto fix this and we depend on eppic extension.
 
 
 Thanks
 Regards
 Alex
