Error compiling 29.7b1 on Arch Linux

[graysky]

I am getting errors relating to HWLOC_OBJ_L4CACHE when building on Arch Linux as shown below. Any thoughts as to what I can do to circumvent?

I modified linux64/makefile like this in order to get the build to work... perhaps I am not quite there yet with it?

Are you attempting to compile mprime v29.7b1? If so, are you unable to use the precompiled images available at https://www.mersenneforum.org/showpo...1&postcount=1?

(Why people routinely omit the name of the software they're asking about or other significant information is a continual puzzle. Or launch a new thread instead of posting in an existing thread about the software of interest, which would reduce the ambiguity.)

Yes, the URL to the source is: http://www.mersenne.org/ftp_root/gim...7b1.source.zip

The precompiled version works, but I maintain both the binary and from-source PKGBUILDs for Arch Linux. I'd like to offer users the option to run one they compile from source.

Download hwloc 2.0.3

That fixed it, thank you. For whatever reason, Arch is currently shipping hwloc v1.11.11 :/
