Subject: [PATCH] Debian multiarch support
Harald Hoyer ab65ae
Harald Hoyer ab65ae
Another solution could be searching in directories found at
Harald Hoyer ab65ae
/etc/ld.so.conf.d/*.conf or adding a new parameter. Here is a patch
Harald Hoyer ab65ae
which adds a new --libdirs parameter, and also a new inst_libdir_file
Harald Hoyer ab65ae
function which will try to expand metacharacters on each lib
Harald Hoyer ab65ae
directory:
Harald Hoyer ab65ae
Harald Hoyer ab65ae
    inst_libdir_file "libdevmapper-event-lvm*.so"
