However, this format actually does not use libxml [*]. Since this is the only user of libxml2 in whole QEMU tree, we can drop all libxml2 checks and dependencies too. It is even more: --enable-parallels configure option was the only option which was silently ignored when it's (fake) dependency (libxml2) isn't installed. Drop all mentions of libxml2. [*] Actually the basis for libxml use were introduced in commit ed279a06c53 ("configure: add dependency") but the implementation was never merged: https://lore.kernel.org/qemu-devel/70227bbd-a517-70e9-714f-e6e0ec431be9@openvz.org/ Signed-off-by: Michael Tokarev Reviewed-by: Stefan Hajnoczi Message-Id: <20220119090423.149315-1-mjt@msgid.tls.msk.ru> Tested-by: Philippe Mathieu-Daudé Reviewed-by: Philippe Mathieu-Daudé [PMD: Updated description and adapted to use lcitool] Reviewed-by: Thomas Huth Signed-off-by: Philippe Mathieu-Daudé Signed-off-by: Alex Bennée Message-Id: <20220121154134.315047-5-f4bug@amsat.org> Reviewed-by: Vladimir Sementsov-Ogievskiy Message-Id: <20220124201608.604599-9-alex.bennee@linaro.org> --- meson.build | 6 ------ block/meson.build | 3 +-- meson_options.txt | 2 -- scripts/checkpatch.pl | 1 - scripts/ci/org.centos/stream/8/x86_64/configure | 1 - scripts/coverity-scan/coverity-scan.docker | 1 - scripts/coverity-scan/run-coverity-scan | 2 +- scripts/meson-buildoptions.sh | 3 --- 8 files changed, 2 insertions(+), 17 deletions(-) diff --git a/meson.build b/meson.build index 5f43355071..82db1e7e74 100644 --- a/meson.build +++ b/meson.build @@ -453,11 +453,6 @@ if not get_option('linux_io_uring').auto() or have_block required: get_option('linux_io_uring'), method: 'pkg-config', kwargs: static_kwargs) endif -libxml2 = not_found -if not get_option('libxml2').auto() or have_block - libxml2 = dependency('libxml-2.0', required: get_option('libxml2'), - method: 'pkg-config', kwargs: static_kwargs) -endif libnfs = not_found if not get_option('libnfs').auto() or have_block libnfs = dependency('libnfs', version: '>=1.9.3', @@ -3496,7 +3491,6 @@ summary_info += {'bzip2 support': libbzip2} summary_info += {'lzfse support': liblzfse} summary_info += {'zstd support': zstd} summary_info += {'NUMA host support': config_host.has_key('CONFIG_NUMA')} -summary_info += {'libxml2': libxml2} summary_info += {'capstone': capstone_opt == 'internal' ?
