Hi Pavel,

Thanks for reporting this issue. Assuming you configure your system with the ./configure script, for the patch to have any effect, the EXV_HAVE_GXXCLASSVISIBILITY compiler define must be set. That's the case if the visibility support is not explicitely disabled with the --disable-visibility configure option and if the compiler has a -fvisibility-inlines-hidden option (see below).

Does the Sun compiler indeed have this option?

AC_MSG_CHECKING([whether to enable g++ visibility support])
AC_ARG_ENABLE(visibility,
    [  --disable-visibility    do not use g++ visibility support ],
    GXX_VISIBILITY=$enableval, GXX_VISIBILITY=yes)
AC_MSG_RESULT($GXX_VISIBILITY)
if test "$GXX_VISIBILITY" = "yes"; then
    AX_CXX_CHECK_FLAG(-fvisibility-inlines-hidden,[],[],[GXX_VISIBILITY=yes],[GXX_VISIBILITY=no])
    if test "$GXX_VISIBILITY" = "yes"; then
        CXXFLAGS="${CXXFLAGS} -fvisibility=hidden -fvisibility-inlines-hidden" 
        AC_DEFINE(HAVE_GXXCLASSVISIBILITY,1)
    fi
    if test "$enable_shared" = "yes"; then
        AC_DEFINE(HAVE_DLL)
    fi
fi

Hi,
studio does not have the -fvisibility* options, however it may ignore them, so I guess that's how the HAVE_GXXCLASSVISIBILITY parameter got enabled.
The equivalent flag to fvisibility-hidden is -xldscope=hidden

from what I gathered, -fvisibility-inlines-hidden does not have an equivalent in Studio
