错误：函数类型在ISO C中不真正兼容[-Werror=pedantic]

当我尝试使用gcc编译包含“sgx lib.h”头文件的C源代码时，它会弹出以下错误：

 In file included from src/trusted/service_runtime/nacl_test_injection_main.c:9:0:

gcc标志如下所示：

'-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'

是否有人知道导致

错误的原因：函数类型在ISO C中不真正兼容[-Werror=pedantic]

顺便说一句，如果我去掉

-pedantic

标志，一切都可以正常编译

谢谢

它指向每个函数的第二个参数，其中只有两个是

const

。另一种可能性是，每个函数定义之间的

struct sockaddr

在某种程度上是不同的？我认为这就是原因：
