FC5中关于gcc的问题
我的系统是FC5，装了gcc-4.1.1-51.fc5，在网上查了一下这个包里有Various compilers (C, C++, Objective-C, Java, ...)多种编译器。但是在安装sqlite时，编译阶段发生错误如下。请问为什么？

[解决办法]
装了gcc-4.1.1-51.fc5，在网上查了一下这个包里有Various compilers (C, C++, Objective-C, Java, ...)多种编译器。
你这个说法错了.
#rpm -qi gcc
Summary : Various compilers (C, C++, Objective-C, Java, ...)
//可能你看到的就是这个说明. 但gcc 只能编译C code
#rpm -qi gcc-c++
Summary : C++ support for GCC
故你还要安装 package gcc-c++
