================================================================= Package Settings ================================================================= sys-block/thin-provisioning-tools-0.1.5-r1 was built with the following: USE="(consolekit) (multilib) (policykit)" ABI_X86="64"
I switched the compiler to gcc-4.7.3 and the package compiled.
Same problem here: gcc-4.6.3 compilation failed gcc-4.7.3 compilation works
So it seems that sys-block/thin-provisioning-tools-0.2.1 depends on gcc-4.7.x. But what can be done to give the user of the ebuild a helping hand - - add a dependency to the ebuild? - add a message if the current compiler is not >=gcc-4.7 and die - do both of the above? OR - let the ebuild check for available compilers and select gcc-4.7 if available otherwise die with a message? GREPing around in the tree lets me find samples for the first two proposed additions, e.g. innoextract-1.4 or nvidia-cuda-sdk-2.02.0807.1535

I can confirm that gcc 4.7.3 needs to be active, otherwise you get "cc1plus: error: unrecognized command line option '-std=c++11'"
*** Bug 477440 has been marked as a duplicate of this bug. ***
Created attachment 353748 [details, diff] minimally intrusive patch to pass -std=c++0x instead of -std=c++11 in CXXFLAGS patching it to pass -std=c++0x instead (attached) works; tested with gcc 4.6 only. I have no clue if gcc 4.3, 4.4, or 4.5 supports enough; earlier ones will obviously not (that is upstream's choice by using the newer version of C++). Also, the ebuild is currently hostile to patches: it does not call epatch_user nor let the implicit call happen.
+ 16 Aug 2013; Patrick Lauer <patrick@gentoo.org> + thin-provisioning-tools-0.2.1.ebuild: + Add gcc version check #476910 This should avoid compile-time failures for now. Better fixes welcome ...
Proposal of changing compilation from -std=c++11 to -std=c++0x of Comment #12 seems to me a less intrusive way of working this around : this will allow thin-provisioning-tools to be used with stable gcc.

Yes, but you should probably keep a version check; just from knowing what features the different gcc releases support, I doubt that gcc 4.3 will successfully compile this package, even though that's the first gcc version that does accept the -std=c++0x flag. I'm away from my gentoo system for quite a while, so I can't test whether gcc 4.5 and/or 4.4 work.
Everything looks to be fine in version 0.2.7 which in now in Portage.
