Even on a 40 core system it looks right and works for me: CC shared_glapi_libglapi_la-entry.lo CC shared_glapi_libglapi_la-mapi_glapi.lo CC shared_glapi_libglapi_la-stub.lo CC shared_glapi_libglapi_la-u_current.lo CC shared_glapi_libglapi_la-u_execmem.lo CC shared_glapi_libglapi_la-table.lo CC glapi_libglapi_la-glapi_gentable.lo CC glapi_libglapi_la-entry.lo CCLD shared-glapi/libglapi.la GEN .libs/install-mesa-links In any case, I'll send a patch to not put install-mesa-links in .libs, or maybe actually make the links rule depend on the links themselves if I can figure out how. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
