ecm-7.0.4.tar.bz2 is not the "release tarball" that WraithX is referring to. There are four links on that page labelled "source code". Below them is one labelled "release tarball". That is the one that contains configure and install-sh. It compiles successfully for me.

I refer to all such compressed-tarchives of e.g. my Mlucas code as "release tarballs" - but finally got the one named so under the 4 you mention, building now. Thx!

Update: Build/test/install completed successfully, but a timing-comparison for the same input and bounds shows a 10x performance hit vs 1 core of my old Haswell - Ugh. I expected "only" a 4-5x hit based on similar comparative timings for the GMP gcd on GIMPS-wavefront-sized inputs.
