When emerging gstreamermm-1.8.0 on my ~amd64 gentoo system, it fails with the error messages:

../gstreamermm/iterator.h: In member function ‘void Gst::IteratorBase<CppType>::swap(Gst::IteratorBase<CppType>&)’:
../gstreamermm/iterator.h:427:39: error: cannot convert ‘GValue {aka _GValue}’ to ‘const GValue* {aka const _GValue*}’ for argument ‘1’ to ‘void g_value_copy(const GValue*, GValue*)’
   g_value_copy(other.current, &current);
                                       ^

This particular bug has been filed and patched upstream however the fix did not work so good when cherry-picked with gcc-6.4.0 in my experience. Would you please try it ?

dev-cpp/gstreamermm-1.8.0 is no longer in the Gentoo tree. dev-cpp/gstreamermm-1.10.0 builds fine with gcc-7.3.0-r1.

Please close this bug.
