Re: [Libguestfs] [nbdkit PATCH v5 4/4] vddk: Drive library loading from libdir parameter.

Unfortunately this series doesn't work with the real VDDK library :-( I see: nbdkit: debug: vddk: config_complete nbdkit: debug: dlopen shim prefix set to /home/rjones/tmp/vddk-6.7.3/vmware-vix-disklib-distrib/lib64 Then a little bit later during VDDK initialization it fails with: nbdkit: debug: VixDiskLib: Could not load default plugins from /home/rjones/tmp/vddk-6.7.3/vmware-vix-disklib-distrib/lib64/libdiskLibPlugin.so: Cannot open library: libcrypto.so.1.0.2: cannot open shared object file: No such file or directory. I was curious if the replacement dlopen() was being called at all, and it is certainly called from plugins/vddk/vddk.c: nbdkit: debug: dlopen: /home/rjones/tmp/vddk-6.7.3/vmware-vix-disklib-distrib/lib64/libvixDiskLib.so.6 flags=2 It's also called from VDDK itself: nbdkit: debug: dlopen: /home/rjones/tmp/vddk-6.7.3/vmware-vix-disklib-distrib/lib64/libdiskLibPlugin.so flags=257 but it's not being explicitly called for libcrypto.so because immediately after the above message I see the error: nbdkit: debug: VixDiskLib: Could not load default plugins from /home/rjones/tmp/vddk-6.7.3/vmware-vix-disklib-distrib/lib64/libdiskLibPlugin.so: Cannot open library: libcrypto.so.1.0.2: cannot open shared object file: No such file or directory. So I guess libcrypto is actually loaded from a DT_NEEDED entry: $ eu-readelf -d /home/rjones/tmp/vddk-6.7.3/vmware-vix-disklib-distrib/lib64/libdiskLibPlugin.so | grep NEEDED NEEDED Shared library: [libpthread.so.0] NEEDED Shared library: [libstdc++.so.6] NEEDED Shared library: [libdl.so.2] NEEDED Shared library: [libcrypto.so.1.0.2] NEEDED Shared library: [libssl.so.1.0.2] NEEDED Shared library: [libexpat.so] NEEDED Shared library: [libz.so.1] NEEDED Shared library: [libvmacore.so] NEEDED Shared library: [libvmomi.so] NEEDED Shared library: [libvim-types.so] NEEDED Shared library: [librt.so.1] NEEDED Shared library: [libgcc_s.so.1] NEEDED Shared library: [libc.so.6] NEEDED Shared library: [ld-linux-x86-64.so.2] which I suppose doesn't actually go through dlopen ...
