I finally reproduced here. Based on the ornl platform script, you're configuring with LDFLAGS=-static and then building with make LDFLAGS=-all-static. Surprisingly, this works fine when building vanilla hwloc, but it breaks inside OMPI. The reason is that OMPI doesn't pass LDFLAGS=-static to hwloc's checks. Inside the vanilla hwloc, the libnuma related checks properly use the static libnuma:
configure:9786: checking for set_mempolicy in -lnuma configure:9811: gcc -o conftest -static conftest.c -lnuma -lpthread >&5 /usr/bin/ld: cannot find -lnuma collect2: ld returned 1 exit status Inside OMPI, there's no -static so it uses libnuma.so: configure:65582: checking for set_mempolicy in -lnuma configure:65607: gcc -o conftest -O3 -DNDEBUG -finline-functions -fno-strict-aliasing -pthread conftest.c -lnuma -lnsl -lutil -lm >&5 configure:65607: $? = 0 configure:65616: result: yes So I think I am passing the ball to Jeff to look at this :) But there's something I am not sure about here: Inside OMPI, passing LDFLAGS=-static seems to mean that "we want to build static libs but they can depend on dynamic libs". Inside hwloc, it means "we want fully static binaries (with no dynamic dependencies)". Is one considered "more standard" than the other? If OMPI is right, is there a way to pass -all-static to libtool at configure time? (putting it inside LDFLAGS breaks configure). If yes, we could try to detect this flag in the hwloc configure and adapt our checks. But I am not sure I want to go there...
