Question

我使用Netbeans 7.4和Cygwin 4.x来编译我的C ++程序时遇到了问题。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。在Netbeans属性，每条路径中都可以正确设置所有内容。但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之后，也遇到了cygwin的这个问题（请参阅setup.exe版本）。我使用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终端编译一些超级简单的东西。

我查了一下：

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

得到了：

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文件夹 C：\ cygwin的\ LIB \ GCC \ x86_64的-PC-cygwin的\ 4.8.1 C：\ cygwin的\ lib中\ GCC \ x86_64的-PC-cygwin的\ 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降级为4.8.1-3并解决了问题。

Netbeans和C ++安装
