Bug#784655: can't rebuild casablanca with newer libstdc++6 (sid)

[Gianfranco Costamagna <costamagnagianfranco@yahoo.it>]

Hi Matthias,

thanks for the quick reply

>are you running sid, or stretch?

in plain sid the package doesn't build at all, in order to trim down the differences I started from a Stretch clean pbuilder environment, and upgraded stuff until I got the problem.



>is the testsuite rebuilt after the new libstdc++ installed? if yes, is the
>libstdc++-5-dev package upgraded as well?


yes, of course the testsuite has been rebuilt, if that matters, I'm compiling with "-std=c++11" flag

so, to resume
starting from stretch, enabling sid repository
apt-get install libstdc++6 libstdc++-5-dev

The following extra packages will be installed:
gcc-5-base libasan2 libatomic1 libcilkrts5 libgcc-5-dev libgcc1 libgomp1 libitm1 liblsan0 libmpx0 libquadmath0 libtsan0 libubsan0


fetch casablanca and try to build.

/casablanca/Release/tests/functional/streams/fstreambuf_tests.cpp:158: error: Failure in OpenForReadDoesntCreateFile2: CHECK_EQUAL(static_cast<int>(std::errc::no_such_file_or_directory), _condFound.value()) where static_cast<int>(std::errc::no_such_file_or_directory)=2 and _condFound.value()=0




>please can you distill down a test case?

the test case seems pretty generic

utility::string_t fname = U("OpenForReadDoesntCreateFile2.txt");
VERIFY_THROWS_SYSTEM_ERROR(OPEN<char>(fname, std::ios_base::in | std::ios_base::binary ).get(), std::errc::no_such_file_or_directory);
std::ifstream is;
VERIFY_IS_NULL(is.rdbuf()->open(fname.c_str(), std::ios::in | std::ios_base::binary));

isn't this something generic?


(sorry I don't undestand too much g++ code, moreover I'm using an embedded UnitTestpp because the Debian one is too outdated)

cheers,

G.
