Sorry but this bug isn't fixed at all: it is possible to keep libgstreamer1.0-dev installed when installing libc++-dev now, but it's still impossible to actually use it because libunwind-dev (the not-llvm version libgstreamer1.0-dev depends on) is still uninstalled and then any attempt to use libgstreamer via pkg-config result in
Package 'libunwind', required by 'gstreamer-1.0', not found and it still can't be used. I have no idea about it but it remains impossible to use libc++ and gstreamer on the same system which is a rather bad limitation. If anybody has any suggestions for a workaround, they would be very welcome, TIA! VZ
