I'm trying to do a out-of-tree build of DPDK 2.0.0 (with make -C and O=), but failing with errors such as In file included from [...]/lib/librte_eal/common/include/rte_eal_memconfig.h:40:0, [...] rte_malloc_heap.h:39:26: fatal error: rte_spinlock.h: No such file or directory Looking in the include/ directory in my build directory, I see a lot of invalid symlinks to things like rte_spinlock.h: lrwxrwxrwx 1 ska users 99 May 4 14:33 rte_spinlock.h -> ../[...]/dpdk/lib/librte_eal/common/include/arch/x86/rte_spinlock.h and I believe that this is caused by my use of multiple mounts: I have my home directory and the source code on NFS, while the build directory is on local disk (under a build/-symlink from my home directory). So using ../ relative to the build directory will actually end up on the local disk, and not work. I guess it should be possible to workaround this by building somewhere else, but perhaps there is some patch to be made in mk/? Any pointer to where to look? // Simon
