Since systemd 209, the various systemd helper libraries are gathered in a single libsystemd, and libsystemd-login is only built when systemd is built with compat libraries support. Since commit https://github.com/systemd/systemd/commit/4de282c "build-sys: drop libsystemd-{id128,daemon,login,journal}.so compat libs" (2016-02-12), these compat libraries are no longer available. This commit checks for both libsystemd and libsystemd-login to ensure we can build on both older and newer systemd versions. https://bugs.freedesktop.org/show_bug.cgi?id=94209 --- configure.ac | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index ca9a15b..de72ea2 100644 --- a/configure.ac +++ b/configure.ac @@ -84,9 +84,16 @@ PKG_CHECK_MODULES(ALSA, [alsa >= 1.0.22]) if test "$with_session_info" = "auto" || test "$with_session_info" = "systemd"; then PKG_CHECK_MODULES([LIBSYSTEMD_LOGIN], - [libsystemd-login >= 42], + [libsystemd >= 209], [have_libsystemd_login="yes"], [have_libsystemd_login="no"]) + if test "$have_libsystemd_login" = "no"; then + # for backward compatibility with older systemd versions + PKG_CHECK_MODULES([LIBSYSTEMD_LOGIN], + [libsystemd-login >= 42], + [have_libsystemd_login="yes"], + [have_libsystemd_login="no"]) + fi if test x"$have_libsystemd_login" = "xno" && test "$with_session_info" = "systemd"; then AC_MSG_ERROR([libsystemd-login support explicitly requested, but some required packages are not available]) fi -- 2.5.0 _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/spice-devel
