# HG changeset patch # User Bryan Hundven <bryanhundven@gmail.com> # Date 1306822450 25200 # Node ID 2b8da144f6a51d1f82f53cd7e564c0dc59f190f0 # Parent 94a989d4e73b60775a1bfcfb0fc05790017f165d config/cc: CC_STATIC_LIBSTDCXX 'depends on' CONFIGURE_has_static_libstdcpp Hide the staticaly linked libstdc++ option if the static libstdc++ is not present, detected at configure time. Add a blind option that says whether static linking is possible at all. It defaults to 'y', but depends on the needed CONFIGURE_* options. For now, it only depends on static libtdc++, but new dependencies can be easily added. Hide the global static toolchain option behind this new option.
