This is done by changing the default build type from\n\"release\" to \"debugoptimized\". Since the latter using O2, we can using\nextra cflags to override that back to O3, which will make little real\ndifference for actual debugging.\n\nFor real debug builds, the user can still do \"meson --buildtype=debug ...\"\nand to remove the debug info \"meson --buildtype=release ...\" can be used.\nThese are all standard meson options.\n\nThe advantage of having debug builds by default using meson settings is\nthat we can then add checks for ABI compatibility into each build, and\ndisable them if we detect that the user has turned off the debug info.\n\nSigned-off-by: Bruce Richardson <bruce.richardson@intel.com>\n---\n meson.build | 8 +++++++-\n 1 file changed, 7 insertions(+), 1 deletion(-)", "diff": "diff --git a/meson.build b/meson.build\nindex b7ae9c8d9..3b7a2e7de 100644\n--- a/meson.build\n+++ b/meson.build\n@@ -7,10 +7,16 @@ project('DPDK', 'C',\n \tversion: run_command(find_program('cat', 'more'),\n \t\tfiles('VERSION')).stdout().strip(),\n \tlicense: 'BSD',\n-\tdefault_options: ['buildtype=release', 'default_library=static'],\n+\tdefault_options: ['buildtype=debugoptimized',\n+\t\t\t'default_library=static'],\n \tmeson_version: '>= 0.47.1'\n )\n \n+# for default \"debugoptimized\" builds override optimization level 2 with 3\n+if get_option('buildtype') == 'debugoptimized'\n+\tadd_project_arguments('-O3', language: 'c')\n+endif\n+\n # set up some global vars for compiler, platform, configuration, etc.\n cc = meson.get_compiler('c')\n dpdk_conf = configuration_data()\n", "prefixes": [ "v3", "1/7" ] }
