I can't easily use GCC 6x in Fedora 26 because it's been built upon GCC 7x. I don't even know if it's possible without rebuilding a lot of packages.\r\nI will try to downgrade GCC and all dependencies as soon as I have some free time.\r\n\r\nIn the meantime I will try to ask on some Eigen3 mailing list or discussion group if someone is willing to take a look into the problem.\r\n\r\nThanks."}}
