Re: [OMPI devel] [PATCH] Open MPI on ARMv5

2012-05-02 Thread Evan Clinton
What I mean to say is that, as far as I can tell, in Open MPI's configure stuff there's a switch based on what it detects the host processor as (and this detection could be overridden by specifying the --host= thing); this is probably not the best way to do it. (sorry for the double-post again, da

Hello Mike, could you please compile with enabled verbosity: make V=1 The missing symbols belong to libz which is a dependency library of ompi/contrib/vt/vt/extlib/otf/otflib/libotf.la - i.e. libotf.la should contain the following line: dependency_libs='-L -lz' If not, Libtool seems to be b
