[edk2] [PATCH] CryptoPkg/OpensslLib: Suppress format warning with extra flag.
Posted by Long Qin 6 years, 11 months ago
Under a certain [outdated] GCC482 compiler, the new-added "-Wno-format"
flag will not take effect, and break the x86_64 build.
This is one known issue in some Ubuntu/GCC-4.8.2 environment, which will
overwrite "-Wno-format" with some default setting.  see more information
and discussion from:
  https://gcc.gnu.org/ml/gcc-help/2014-03/msg00003.html
  https://wiki.ubuntu.com/ToolChain/CompilerFlags
This patch adds one extra "-Wno-error=format" for gcc x86_64 builds to
suppress this warning.
