[libvirt] [PATCH] build: fix build with autoconf 2.59

Commit 350583c8 broke development on a RHEL 5 box, where the ancient Autoconf 2.59 lacks AS_VERSION_STRING. Rather than backport the complex awk script that newer autoconf uses for true strverscmp comparisons from the shell, it was easier to just open-code a shell case statement. * configure.ac (qemu_version): Open-code a replacement for AS_VERSION_CHECK. --- Pushing under the build-breaker rule. 'make' still failed: util/virfile.c: In function 'virFileLoopDeviceAssociate': util/virfile.c:580: error: 'LO_FLAGS_AUTOCLEAR' undeclared (first use in this function) But at least I got past the './autogen.sh' failure. configure.ac | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/configure.ac b/configure.ac index ba5a3cd..d650626 100644 --- a/configure.ac +++ b/configure.ac @@ -1121,8 +1121,11 @@ if test "$with_qemu:$with_yajl" = yes:check; then else [qemu_version_sed='s/.*ersion \([0-9.,]*\).*/\1/'] qemu_version=`$QEMU -version | sed "$qemu_version_sed"` - AS_VERSION_COMPARE([$qemu_version], [0.15], - [], [with_yajl=yes], [with_yajl=yes]) + case $qemu_version in + [[1-9]].* | 0.15.* ) with_yajl=yes ;; + 0.* | '' ) ;; + *) AC_MSG_ERROR([Unexpected qemu version string]) ;; + esac fi fi fi -- 1.7.11.4
