I think what confuses me is that keep talking about a single binary, but clearly there is this separate vddk DSO, and there is talk of plugins. So it seems to me that multiple files are involved already?
nbdkit is a standalone binary that happens to be able to load plugins from a well-known path, eg nbdkit-vddk-plugin.so. nbdkit knows the path for plugins, and there's a wrapper allowing it to get local plugins even when it's still in the build directory. Adding another file would mean another path (or overloading the meaning of the plugin path) and just makes the whole thing more fragile and complex. Having said all that, what would also solve this is either an API for updating LD_LIBRARY_PATH after the program has started; or making setenv ("LD_LIBRARY_PATH",...) DTRT*; or some kind of dlopen() variant which takes a library path as an extra parameter. Rich. * “Why does setenv ("LD_LIBRARY_PATH") not work?” has several stackoverflow answers. Apparently even the JDK has to work around this by re-execing. https://www.google.com/search?q=setenv+%22LD_LIBRARY_PATH%22+site:stackoverf... -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-builder quickly builds VMs from scratch http://libguestfs.org/virt-builder.1.html
