Building for zen platform.
Erling D. Andersen
./configure --enable-threading=pthreads zen
as far as I recall. But now that does not work since I get the build errors below. Should I just build for AMD64 and will that give me the best performance on recent AMD CPUs?

Sorry to hear about your trouble. The configuration command you gave:
./configure --enable-threading=pthreads zen
should certainly work. And while I don't currently have access to AMD
hardware on which to test, there isn't anything architecture-specific
about running configure with those arguments.
Perhaps more importantly, however, judging from your configure output,
it appears you are not using a github clone or an official github
release; the latest version that I have released is 0.5.0. I'm guessing
you are using a version managed by AMD, and so I can't vouch for its
current working state.
If you would like to continue using the AMD version, I suggest you
contact their support staff and/or open an issue at the AMD github site.
Otherwise, I suggest you try a git clone from our github site [1]. (The
head of the 'master' branch is stable and safe for general use, as it
almost always is. I encourage people to use clones since they are much
easier to update than an official release.)

Hi Erling,
Could you share the details on this CPU ? log seems to indicate failure to detect a zen based CPU
