Netbeans和C ++安裝

Question

我在使用Netbeans 7.4和Cygwin 4.x編譯C ++程序時遇到了一個小問題。 我已經完成了與netbeans教程一樣的所有操作。 我已經安裝了gcc，gdb，g ++並制作了編譯器。 在Netbeans屬性中的每條路徑中，所有內容均已正確設置。 但是我仍然遇到同樣的問題，我不知道這是什么問題。 我正在嘗試從Netbeans編譯Hello示例。 請幫我。 這是錯誤日志：

在最后一次更新到2.830（請參閱setup.exe版本）之后，cygwin也遇到了此問題。 我正在使用64位版本。 要驗證我們是否存在相同的問題，請嘗試使用g ++ usgin cygwin終端手動編譯一些超級簡單的東西。

我檢查了：

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

並得到：

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.

我注意到這里有兩個gcc文件夾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提供4.8.2

運行Cygwin的最新Setup.exe並查找已安裝的數據包，表明gcc-core和gcc-g ++的版本不匹配：

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

我將gcc-core降級為4.8.1-3，並修復了該問題。
