This can be perfectly normal. The .la files are not necessary. > $ ls /usr/lib/x86_64-linux-gnu/libnuma.* > /usr/lib/x86_64-linux-gnu/libnuma.a /usr/lib/x86_64-linux-gnu/libnuma.so.1 > /usr/lib/x86_64-linux-gnu/libnuma.so So you now do actually have everything you should need. Strange. If -lnuma still isn't found, /usr/lib/x86_64-linux-gnu is not in your standard search path (which would be odd, but possible. Do you by any chance try this on a multi-arch installation with i386 being the default (so that the numa library that is x86_64 cannot be linked, and you would need to install the corresponding i386 library instead - not that I would suggest that). > Of course, it would help to eventually understand why -lnuma also > comes into the liking sequence. True. From the configuration script and the absence of the .la file I would think it needs to be something else than that. On a single machine (like a workstation or laptop), I found that _not_ using hwloc can actually be an advantage anyway in some circumstances (multiple MPI jobs _not_ all tied to the first core).
