I've updated ports to -r484783 and an amd64 -> armv7 poudriere-devel/qemu-user-static cross-build is in progress. devel/cmake completed fine, overall about 63 ports have. The 1 port failure is not tied to qemu-arm-static issues. It will be hours before lang/gcc8 would finish. There are somewhat over 70 ports to go overall. So far so good. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
