Re: [Libguestfs] [PATCH] appliance: Fix searching for shared libraries on usr-merged Debian systems

If /lib is a symlink to usr/lib, paths to shared libraries as determined by ld.so may differ from dpkg's file lists. We turn the filename search pattern into a glob expression by prefixing it with a '*', so the required packages are found again: $ dpkg -S /lib/x86_64-linux-gnu/libpcre2-8.so.0 dpkg-query: no path found matching pattern /lib/x86_64-linux-gnu/libpcre2-8.so.0 $ dpkg -S */lib/x86_64-linux-gnu/libpcre2-8.so.0 libpcre2-8-0:amd64: /usr/lib/x86_64-linux-gnu/libpcre2-8.so.0 --- appliance/Makefile.am | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/appliance/Makefile.am b/appliance/Makefile.am index a213e12be4..6dd1df75a6 100644 --- a/appliance/Makefile.am +++ b/appliance/Makefile.am @@ -84,7 +84,7 @@ if HAVE_RPM QUERY_FILES_CMD := xargs rpm -qf --qf '%{name}\n' endif if HAVE_DPKG -QUERY_FILES_CMD := xargs dpkg -S | cut -d: -f1 +QUERY_FILES_CMD := sed -e 's,^/,\*/,' | xargs dpkg -S | cut -d: -f1 endif if HAVE_PACMAN QUERY_FILES_CMD := xargs pacman -Qo | sed -r 's/.* is owned by ([^ ]+) .*/\1/'
