Microsoft CRT defines Windows-specific secure alternatives to standard library functions and triggers warnings when "insecure" functions are used [1]. However, calling code already has all necessary checks around those functions, so these warnings are not useful for DPDK. MinGW provides its own CRT without this issue.

It is probably a consequence of building more libraries for Windows. config/meson.build | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/config/meson.build b/config/meson.build index c02802c18..a3154e29c 100644 --- a/config/meson.build +++ b/config/meson.build @@ -279,6 +279,11 @@ if is_windows add_project_arguments('-D__USE_MINGW_ANSI_STDIO', language: 'c') endif + # Disable secure CRT deprecated warnings for clang + if cc.get_id() == 'clang' + add_project_arguments('-D_CRT_SECURE_NO_WARNINGS', language: 'c') + endif + add_project_link_arguments('-lws2_32', language: 'c') # Contrary to docs, VirtualAlloc2() is exported by mincore.lib -- 2.25.1
