c++ - Netbeans 和 C++ 安装

Question

我在使用 Netbeans 7.4 和 Cygwin 4.x 编译我的 C++ 程序时遇到了一个小问题。我已经完成了 netbeans 教程中的所有操作。我已经安装了 gcc、gdb、g++ 和 make 编译器。一切都在 Netbeans 属性中正确设置，每条路径。但是我仍然遇到同样的问题，我不知道这是什么问题。我正在尝试从 Netbeans 编译 Hello 示例。请帮我。这是错误日志:

在上次更新到 2.830(参见 setup.exe 版本)后，cygwin 也遇到了这个问题。我使用的是 64 位版本。要验证我们是否有同样的问题，请尝试使用 g++ usgin cygwin 终端手动编译一些超简单的东西。

我检查过:

$ echo -e "#include <iostream>\n int main() { return 0; }" | g++ -xc++ -

得到:

In file included from /usr/include/sys/reent.h:14:0,
                 from /usr/include/wchar.h:6,
                 from /usr/lib/gcc/x86_64-pc-cygwin/4.8.1/include/c++/cwchar:44,
                 from /usr/lib/gcc/x86_64-pc-cygwin/4.8.1/include/c++/bits/postypes.h:40,
                 from /usr/lib/gcc/x86_64-pc-cygwin/4.8.1/include/c++/iosfwd:40,
                 from /usr/lib/gcc/x86_64-pc-cygwin/4.8.1/include/c++/ios:38,
                 from /usr/lib/gcc/x86_64-pc-cygwin/4.8.1/include/c++/ostream:38,
                 from /usr/lib/gcc/x86_64-pc-cygwin/4.8.1/include/c++/iostream:39,
                 from <stdin>:1:
/usr/include/sys/_types.h:72:20: fatal error: stddef.h: No such file or directory
 #include <stddef.h>
                    ^
compilation terminated.

我注意到这里有两个gcc的文件夹 C:\cygwin\lib\gcc\x86_64-pc-cygwin\4.8.1 C:\cygwin\lib\gcc\x86_64-pc-cygwin\4.8.2

和 g++ --version 给出 4.8.2

运行 Cygwin 的最新 Setup.exe 并查找已安装的数据包显示 gcc-core 和 gcc-g++ 的版本不匹配:

gcc-core = 4.8.2-1
gcc-c++ = 4.8.1-3

我将 gcc-core 降级到 4.8.1-3 并解决了这个问题。
