Re: [libvirt] [PATCH] wireshark: Install to generic plugin directory

There has been a report on the list [1] that we are not installing the wireshark dissector into the correct plugin directory. And in fact we are not. The problem is, the plugin directory path is constructed at compile time. However, it's dependent on the wireshark version, e.g. /usr/lib/wireshark/1.12.6/plugins/

This is rather unfortunate, because if libvirt RPMs were built with one version, but installed on a system with newer one, the plugins are not really loaded. This problem lead fedora packagers to unify plugin path to: /usr/lib/wireshark/plugins/ Cool! But this was enabled just in wireshark-1.12.6-4. Therefore, we must require at least that version. And while at it, on some distributions, the wireshark.pc file already has a variable that defines where plugin dir is. Use that if possible. 1: https://www.redhat.com/archives/libvirt-users/2015-October/msg00063.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- libvirt.spec.in | 6 ++++-- m4/virt-wireshark.m4 | 7 ++++++- 2 files changed, 10 insertions(+), 3 deletions(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 9dff994..469bfca 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1170,7 +1170,7 @@ virtualization capabilities of recent versions of Linux (and other OSes). %package wireshark Summary: Wireshark dissector plugin for libvirt RPC transactions Group: Development/Libraries -Requires: wireshark +Requires: wireshark >= 1.12.6-4 Requires: %{name}-client = %{version}-%{release} %description wireshark @@ -1561,6 +1561,8 @@ rm -f $RPM_BUILD_ROOT%{_libdir}/libvirt/connection-driver/*.a %endif %if %{with_wireshark} rm -f $RPM_BUILD_ROOT%{_libdir}/wireshark/plugins/*/libvirt.la +mv $RPM_BUILD_ROOT%{_libdir}/wireshark/plugins/*/libvirt.so \ + $RPM_BUILD_ROOT%{_libdir}/wireshark/plugins/libvirt.so %endif # Temporarily get rid of not-installed libvirt-admin.so @@ -2279,7 +2281,7 @@ exit 0 %if %{with_wireshark} %files wireshark -%{_libdir}/wireshark/plugins/*/libvirt.so +%{_libdir}/wireshark/plugins/libvirt.so %endif %if %{with_lxc} diff --git a/m4/virt-wireshark.m4 b/m4/virt-wireshark.m4 index 47204ed..199317e 100644 --- a/m4/virt-wireshark.m4 +++ b/m4/virt-wireshark.m4 @@ -28,7 +28,12 @@ AC_DEFUN([LIBVIRT_CHECK_WIRESHARK],[ dnl Check for system location of wireshark plugins if test "x$with_wireshark_dissector" != "xno" ; then if test "x$with_ws_plugindir" = "xcheck" ; then - ws_plugindir="$libdir/wireshark/plugins/$($PKG_CONFIG --modversion wireshark)" + ws_plugindir="$($PKG_CONFIG --variable plugindir wireshark)" + if test "x$ws_plugindir" = "x" ; then + dnl On some systems the plugindir variable may not be stored within pkg config. + dnl Fall back to older style of constructing the plugin dir path. + ws_plugindir="$libdir/wireshark/plugins/$($PKG_CONFIG --modversion wireshark)" + fi elif test "x$with_ws_plugindir" = "xno" || test "x$with_ws_plugindir" = "xyes"; then AC_MSG_ERROR([ws-plugindir must be used only with valid path]) else -- 2.4.10 -- libvir-list mailing list libvir-list(a)redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
