c++ - Compilation error: "stddef.h: No such file or directory" -


whenever try compile code ends error:

    in file included /usr/include/wchar.h:6:0,              /usr/lib/gcc/i686-pc-cygwin/4.9.2/include/c++/cwchar:44,              /usr/lib/gcc/i686-pc-cygwin/4.9.2/include/c++/bits/postypes.h:40,              /usr/lib/gcc/i686-pc-cygwin/4.9.2/include/c++/iosfwd:40,              /usr/lib/gcc/i686-pc-cygwin/4.9.2/include/c++/ios:38,              /usr/lib/gcc/i686-pc-cygwin/4.9.2/include/c++/ostream:38,              /usr/lib/gcc/i686-pc-cygwin/4.9.2/include/c++/iostream:39,              test.cpp:1:     /usr/include/sys/reent.h:14:20: fatal error: stddef.h: no such file or directory     #include <stddef.h>                 ^     compilation terminated.

the code trying compile is:

#include <iostream> using namespace std;  int main() {     cout << "hello world! :d";     return 0; }

the error because gcc-core package , gcc-g++ not of same version. either downgrade 1 of them solve problem or update both libraries. updating both libraries recommended way.
