Re: [libvirt] [PATCH V3 1/2] libxl: drop support for Xen < 4.6

Since Xen 4.6 contains a pkgconfig file, drop the now unused code that falls back to using LIBVIRT_CHECK_LIB in the absence of pkgconfig file.

- dnl pkgconfig file not found, fallback to lib probe - if test "x$with_libxl" = "xno" ; then - with_libxl="$old_with_libxl" - - dnl LIBXL_API_VERSION 4.4.0 introduced a new parameter to - dnl libxl_domain_create_restore for specifying restore parameters. - dnl The libxl driver will make use of this new parameter for specifying - dnl the Xen migration stream version. Specify LIBXL_API_VERSION to trigger - dnl an error if there is too old xenlight - libxlold_CFLAGS="$CFLAGS" - CFLAGS="$CFLAGS $LIBXL_API_VERSION" - LIBVIRT_CHECK_LIB([LIBXL], [xenlight], [libxl_ctx_alloc], [libxl.h], [fail="1"]) - CFLAGS="$libxlold_CFLAGS" - - if test $fail = 1; then - AC_MSG_ERROR([You must install the libxl Library from Xen >= 4.4 to compile libxenlight driver with -lxl]) - fi - fi
