当我尝试编译C源代码时，包括＆＃34; sgx-lib.h＆＃34;头文件，使用gcc，它弹出以下错误：
In file included from src/trusted/service_runtime/nacl_test_injection_main.c:9:0:

cc1: all warnings being treated as errors
gcc标志如下：
'-fPIE', '-m64', '-Wall', '-pedantic', '-Wextra', '-Wno-long-long', '-Wswitch-enum', '-Wsign-compare', '-Wundef', '-fdiagnostics-show-option', '-fvisibility=hidden', '-Werror', '-Wno-variadic-macros', '--param', 'ssp-buffer-size=4', '-O2', '-static', '-fno-stack-protector', '-Isrc/trusted/service_runtime/opensgx/include', '-Isrc/trusted/service_runtime/opensgx/share/include', '-Isrc/trusted/service_runtime/opensgx/libsgx/include', '-fPIC', '-fvisibility=hidden', '-std=gnu11', '-nostdlib'
有谁知道error: function types not truly compatible in ISO C [-Werror=pedantic]的原因是什么？
顺便说一下，如果我删除-pedantic标志，那么一切都很好。
谢谢！
