It seems to be a problem with 'old' gcc 5.x libraries. GCC 5.x is *old* but seeing that Ubuntu supports Xenial for five years, i.e. until 2021, I guess we need to fix this. Newer compiler version are able to make the same inference as I did above by themselves. > Please fix this or give me a hint for additional compiler options. Just pushed 5e74e1b7940e32b2a6f387410755149d21672a4f to fix this. There are no other occurences of <> in any of the C++ code. > Many thanks in advance. You're welcome.
